IT IS FULLY FUNCTIONAL AND IN PERFECT CONDITION AS PHOTOS SHOWN ! ( RETAIL NEW:$1,899)OVERVIEW:Native DSD and PCM Conversion, Studio-Quality Naturalism, and Trademarked Jitter Reduction Equate to Stellar Sound: U.S.A.-Built Benchmark DAC 3 B Also Features Harmonic CompensationWant a reference DAC stripped to the core to keep costs manageable? Meet the Benchmark DAC3 B, which sounds exactly like its more expensive sibling, DAC3 HDC. How? It uses the very same circuit board and audio path, and simply eliminates a few extra features – the headphone amplifier, volume control, and analog inputs – to focus on the task at hand. Bolstered by an ESS Technologies ES9028PRO chip, trademarked jitter attenuation system, and active second and third harmonic compensation, DAC3 B offers native PCM and DSD conversion to analog. Youll experience finite details, spot-on precision, impeccable timing, and absorbing immediacy. Benchmark, indeed.To make system integration easy, the American-designed and -built DAC3 B retains IR remote control (handset optional), 12 V trigger, and a programmable auto-on feature. It also adds a control-lock feature that turns off the remote control and locks the keypad to prevent tampering and accidental changes. The optional 1/2-width rack-mount faceplate allows the mounting of two units in a single 1-RU rack space. Benchmarks extended five-year warranty and our 100% Satisfaction Guarantee do the rest.Sonically Neutral Studio-Quality MonitoringAll Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. For this reason, DAC3 converters are ideal for critical reference-quality professional systems. Unlike many competing products, DAC3 is not designed to add euphonic coloration to the audio. Instead it is created to be as uncolored and natural as possible.Virtually Perfect Jitter Reduction With Trademarked UltraLock3 SystemThe lightning-fast UltraLock3 is an improved version of the UltraLock2 system and provides virtually perfect jitter attenuation. DSP processing is 32-bits, DSP headroom is 3.5dB, sample rate is 211 kHz, and jitter-induced distortion and noise is at least 140dB below the level of the music - well below the threshold of hearing. Benchmarks UltraLock3 system eliminates all audible jitter artifacts.High Headroom Features 3.5dB Excess for Coloration-Free PlaybackAll of the digital processing in DAC3 is designed to handle signals as high as +3.5 dBFS. Most digital systems clip signals that exceed 0 dBFS. The 0 dBFS limitation seems reasonable, as 0 dBFS is the highest sinusoidal signal level that can be represented in a digital system. However, a detailed investigation of the mathematics of PCM digital systems will reveal that inter-sample peaks may reach levels slightly higher than +3 dBFS while individual samples never exceed 0 dBFS. These inter-sample overs are common in commercial releases, and are of no consequence in a PCM system until they reach an interpolation process. But virtually all audio D/A converters use an interpolation process. The interpolation process is absolutely necessary to achieve 24-bit state-of-the art conversion performance. Unfortunately, inter-sample overs cause clipping in most interpolators. This clipping produces distortion products that are non-harmonic and non-musical . We believe these broadband distortion products often add a harshness or false high-frequency sparkle to digital reproduction. DAC3 avoids these problems by maintaining at least 3.5dB of headroom in the entire conversion system.Multi-Mode Asynchronous USB System Supports USB2.0 and DSDBenchmarks USB system supports USB Audio 2.0, DSD, and USB Audio 1.1. It will follow sample-rate changes initiated by the computer and/or the media playback software. In all modes, the USB communications are asynchronous in order to eliminate unnecessary sources of jitter. DAC3 has a low-jitter master clock that controls the transfer of audio data from the computer to the USB sub-system. The computer asynchronously transfers audio data to a buffer in DAC3. The contents of the buffer are then asynchronously transferred to the D/A conversion subsystem. This second asynchronous transfer eliminates any traces of jitter that accumulate as the data is transferred between the USB and conversion subsystems. No traces of jitter-induced distortion are measurable to Benchmarks measurement limits (better than -150 dBFS). So you can enjoy the convenience of computer playback without compromise. The asynchronous USB system supports USB Audio 2.0 for high-resolution 192kHz and DSD playback. An asynchronous, driverless USB Audio 1.1 mode supports sample rates up to 96kHz. This USB mode can be selected from the front panel or from the remote control. The USB subsystem remains active when DAC3 is powered down to prevents interruptions to the computer playback operations and eliminate the need to reconfigure the computer every time the converter is turned on.Incredibly Low THD Via Quad 32-Bit Balanced ConversionFour balanced 32-bit D/A converters deliver audio to Benchmarks low-impedance current to voltage converters. The 4:1 redundancy reduces noise and distortion to beguiling levels. The conversion system at the core of DAC3 is superb and the analog circuits that follow the D/A converter carefully designed. The conversion system in DAC3 achieves a 6dB signal-to-noise improvement through the use of 4:1 summing. The ES9028PRO D/A is an 8-channel 32-bit converter. In DAC3, four channels are summed in the analog domain to form each of the two output channels. he 4:1 summing also improves the THD. The non-linearities in individual conversion channels are averaged across the four summed channels and incoherent non-linearities are attenuated by 6dB.Two Harmonic Compensation SystemsThe ES9028PRO chip has two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter. Benchmarks ultra-clean analog output stages allow these systems to be fully leveraged in DAC3. To Benchmarks knowledge, no other D/A converter has lower THD.Native DSD ConversionAll digital inputs on the DAC3 support native PCM or DSD conversion. From any input, DSD is transported with bit accuracy over DoP 1.1. DSD and PCM are both natively converted to analog. There are no DSD to PCM or PCM to DSD conversions to compromise the quality of the music. The DAC3 conversion system seamlessly switches between native PCM and native DSD conversion.Direct Connectivity to Power AmplifiersDAC3 converters are designed to directly drive power amplifiers and speakers. Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). This unique Benchmark feature optimizes the gain staging between the DAC and the power amplifier. When audio stages are properly matched, each component in the audio chain is able to operate at its optimum signal level, and system performance is significantly improved.Sample-Rate and Word-Length IndicatorsEver wonder why that 192 kHz 24-bit download on your computer just doesnt sound right? Your media player may be down-sampling to 44.1 kHz and/or truncating to 16-bits. Many computers and media players apply poor-quality sample rate conversion and truncation. Fortunately these problems can be eliminated with the selection a good frequency-agile media player. The sample-rate and word-length displays on the DAC3 confirm the proper operation of your media player.

DAC3 B - Reference Quality - Basic Features The DAC3 B is the basic D/A converter in Benchmark's DAC3 converter series. The DAC3 B is the ideal converter to use in front of Benchmark's HPA4 headphone amplifier or LA4 line amplifier. It is also ideal for many professional studio applications. It delivers the full performance of the flagship DAC3 HGC, but eliminates the volume control, the analog inputs, the mute and polarity controls, and the headphone amplifier. To make system integration easy, the DAC3 B retains IR remote control (handset optional), 12 V trigger, and the programmable auto-on feature. The DAC3 B adds a control-lock feature that turns off the remote control and locks the keypad to prevent tampering and accidental changes. The optional 1/2-width rack-mount faceplate allows the mounting of two units in a single 1-RU rack space. The DAC3 B sounds exactly like the DAC3 HGC because it uses the exact same circuit board and the exact same audio path. Benchmark has simply eliminated the unnecessary parts to deliver a stripped down race car of a converter. If you want a basic D/A converter that delivers the finest conversion available, the DAC3 B is for you. The DAC3 B is a 2-channel D/A converter featuring the new ESS Technologies ES9028PRO converter chip. The DAC3 converter has lower THD and THD+N noise than Benchmark's DAC2 converters. Benchmark's DAC1 and DAC2 D/A converter families have been the reference to which other converters have been compared. It is rare to find a converter review that does not draw comparisons to the DAC1 or the DAC2. Benchmark converters are in daily use at many of the world's finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar again ... the DAC3 defines a new reference. Reference Performance The DAC3 delivers outstanding musical detail and precise stereo imaging. It employs an advanced high-headroom digital filter design, and a high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock3™ jitter attenuation system. Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters. Four balanced 32-bit D/A converters are summed together to create each balanced analog output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC3 industry-leading performance. DAC3 vs. DAC2 The DAC3 builds upon Benchmark’s highly successful DAC2 product family. The DAC3 maintains the familiar DAC2 form factor and feature set, but adds the higher performance available from the new ES9028PRO D/A converter. The DAC3 offers the following improvements over the DAC2: Active 2nd Harmonic Compensation Active 3rd Harmonic Compensation Lower THD+N Lower passband ripple Improved frequency response Faster PLL lock times Faster switching between input signals DAC3 vs. DAC1 The DAC3 and DAC2 added these features that were not found on the DAC1: Asynchronous 192kHz USB Audio 2.0 32-bit D/A conversion system Word Length Display Sample Rate Display Direct DSD D/A Conversion Bi-Directional 12V Trigger Power Switch with Auto-On Function Digital Pass-Through High-Headroom DSP Additional I/O Native DSD Conversion All digital inputs on the DAC3 support native 192 kHz PCM or DSD64 conversion. From any input, DSD is transported with bit accuracy over DoP 1.1. DSD and PCM are both natively converted to analog. There are no DSD to PCM or PCM to DSD conversions to compromise the quality of the music. The DAC3 conversion system seamlessly switches between native PCM and native DSD conversion. DSD over DoP 1.1 is supported by many media players, and DSD downloads are now available from several sources. Sonically-Neutral Studio Monitoring All Benchmark converters are designed for maximum transparency. This transparency is absolutely essential in the studio monitoring chain. For this reason, DAC3 converters are ideal for critical reference-quality professional systems. Unlike many competing products, the DAC3 is not designed to add euphonic coloration to the audio. Instead it is designed to be as uncolored and natural as possible. Step Into the Studio When Benchmark's professional converters are used in hi-fi applications, studio-quality sound can be enjoyed in a home environment. Enjoy pure music without any coloration from the electronics. Hear the music exactly the way it was heard in the studio, and exactly the way the artists intended. Discover the natural, uncolored, analog sound of the DAC3. Sit in the Performance Space Transparent sound can go beyond replicating the studio experience. Recordings that have been produced with a natural and unprocessed sound can transport you to the performance space. But, this can only happen when the entire playback chain is selected for maximum transparency. This experience of being there cannot be created by systems that are designed to add warmth or euphonic color to the music. Retails for 1900.00$ on benchmarks website. This unit is like new condition. Has been tested and works great! Much more about this unit can be found on benchmarks website. I will also be including a good quality usb cable with the unit.

This feature disables the IR remote control and the front panel buttons.Digital Pass ThroughThe second coaxial input on the DAC3 can be reconfigured as a digital output. In output mode, any selected digital input (including USB) will pass through to the coaxial output. The digital pass through is bit-transparent and even supports DSD (DoP 1.1). Dolby digital and DTS formats can also be passed through to a surround processor.Bi-Directional 12 Volt TriggerBenchmark re-invents the 12 volt trigger. The trigger connection on the DAC2 can be used as an input, an output, or both. It is compatible with any common 12 volt trigger input or output. The trigger can be used to turn a power amplifier on or off automatically. The DAC3 will also respond to a 12 volt trigger to follow the actions of another audio component.Power SwitchThe power switch can place the DAC3 in standby, or full shut down. In full shut down, the unit will still respond to the trigger input and the IR remote control. Power consumption is less than 0.5 W in full shut down.Low Power ConsumptionThe DAC3 uses high-efficiency low noise power supplies and may be operated from any standard international voltage without adjustment. Power consumption is 12 W typical.Distributed Power RegulationTo achieve the lowest possible noise, the DAC3 uses distributed power supply regulation. Each critical subsystem has at least one dedicated low-noise voltage regulator.Awards

Maybe some waiting time.Einmalige Chance!Näheres finden Sie auf der Webseite des Herstellers!Benchmark Media DAC3 HGCDer DAC 3 ist ein kleines Gerät, das vollständig die Funktionen eines Vorverstärkers (auch mit analogen Eingängen), Digital-Analog-Wandlers und Kopfhörerverstärker vereint - in Studioqualität.Zusammen mit dem passenden Endverstärker AHB2 hat man schon eine in Abmessungen kleine Highend-Anlage. Ausführung in Silber oder Schwarz. Es ist zusätzlich eine schwarze Fernbedienung (Remote) erhältlich. Technik des Benchmark DAC3Verringerung harmonische VerzerrungenHybride LautstärkeregelungUltraLock3™ Jitter VerringerungHigh-Headroom DSPMulti-Mode Asynchronous USB Audio SystemQuad 32-bit Symmetrischer D/A WandlerVerteilte Netzteil-RegelungenVerringerung harmonischer VerzerrungenDer verwendete ES9028PRO hat zwei unabhängige Systeme zur Verringerung harmonischer Verzerrungen, die fast vollständig die Verzerrungen der zweiten und dritten Oberwelle erreichen. Der Benchmark hat zudem ultra-saubere analoge Ausgangsstufen. Nach aktuellem Stand gibt es keinen anderen DAC mit niedrigeren THD Verzerrungen als der DAC3.HGC = Hybrid Gain ControlHGC ist Benchmarks einzigartiges Hybrid Gain Control system. Der DAC3 kombiniert eine aktive Verstärkungsregelung, ein passives Widerstandsnetzwerk, eine 32-bit digitale Verstärkungsregelung und eine fernbedienbare motorbetriebene Lautstärkeregelung. Die analogen Eingänge werden nicht digitalisiert und digitale Eigänge gehen nicht über eine analoge Lautstärkeregelung Digitaleingänge werden über ein 32 Bit DSP System gesteuert. Das DSP gewährleistet präzise L/R Balance, und eine präzise Stereo Abbildung,Das passive Widerstandsnetzwerk erlaubt verzerrungsfreie Verstärkungsregelung ohne die Dynamik zu begrenzenr. Widerstände optimieren die Verstärkungsfaktoren der Stufen zwischen dem DAC3 und dem Endverstärker. Diese Optimierung ist entscheidend für die erreichbare Gesamtqualität der Kette.UltraLock3™ Jitter Attenuation SystemUltraLock3™ erreicht die Phasengenauigkeit innerhalb von nur 6 ms. DSP Verarbeitung mit 32 bit, ein DSP Headroom von 3,5 dB, Eine sample rate von 211 kHz, und Jitter-bedingte Verzerrungen 140 dB unterhalb des Musiksignals - einfach nicht hörbar.High Headroom DSP - mit 3.5 dB Zusatz Digital HeadroomDie digitale Signalverarbeitung erlaubt eine Verarbeitung der Signale bis +3.5 dBFS. Die meisten Digitalprozessoren clippen Signale oberhalb von 0 dBFS. Die 0 dBFS Grenze scheimt hinreichend, da 0 dBFS das höchste Sinussignallevel im Signalprozessor ist .Eine genaue Untersuchung hat ergeben, dass in PCM-Systemen inter-sample peaks Werte von leicht über +3 dBFS erreichen können, auch wenn die einzelnen Abtastwerte niemals 0 dBFS überschreiten.Diese inter-sample overs sind allgemein häufig auf kommerziellen Aufnahmen zu finden, sind aber erst dann von Bedeutung, wenn ein Interpolationsprozess beginnt. Aber fast alle DACs nutzen aus verschiedensten Gründen Interpolationsprozesse.Inter-sample overs führen in den meisten Wandlern zum clipping. Das clipping erzeugt disharmonische, unmusikalische Verzerrungskomponenten. Benchmark gibt an , dass diese Verzerrungen eine harsche Wiedergabe oder unnatürlichen Hochtöne erzeugen. Durch den zusätzlichen 3,5 dB headroom werden diese Verzerrungen vermieden. Benchmark sieht darin einen großen klanglichen Fortschritt.Multi-Mode Asynchronous USB SystemBenchmarks USB system unterstützt USB Audio 2.0, DSD, and USB Audio 1.1. Der DAC3 hat eine Master Clock mit geringem Jitter. Der Computer tranferiert Daten im asynchronen Modus zum Buffer des DAC. Der Inhalt des Buffer wird dann widerum asynchron zum D/A System übertragen. diese zweite asynchrone Übertragung eliminiert alle Spuren von Jitter Keine Spuren von Jitterbedingten Verzerrungen sind mit der aktuellen Messtechnik messbar (besser als -150 dBFS). Das ist State of the Art.Keine Treiber sind für MAC OS erforderlich, lediglich für 192 kHz and DSD muss ein Windows Treiber installiert werden. USB Audio 1.1 mode unterstützt Bitraten bis 96 kHz. Dieser USB mode kann gewählt werden, damit ist ein plug and play mit allen Betriebssystemen möglich.Quad 32-bit Symmetrisches Conversion SystemVier symmetrische 32-bit D/AWandler ergeben eine Wandlung von Strom zu Spannung mit niedriger Impedanz. Die 4:1 Redundanz verringert auch das Rauschen und die Verzerrungen. Durch die 4:1 Addition erreicht der DAC3 eine Verbesserung um 6 dB von Signal-Rausch-Abstand und THD.Phasen - SchalterAufnahmen mit verkehrter Phase können invertiert geschaltet werden.Home Theater BypassDer DAC3 kann in ein Heimkino integriert werden, dafür hatt er eine Durchschleif-FunktionDigital Pass ThroughDer zweite Coax-Eingang kann auch als digitaler Ausgang konfiguriert werden.Bi-Directional 12 Volt TriggerDer Trigger-Anschluß kann zum automatischen Ein/Aus von Geräten genutzt werden.NetzschalterDer Netzschalter schaltet in Standby oder Total-Aus. Auch im Total-Aus reagiert er noch auf Trigger oder Fernbedienung, der Stromverbrauch ist dann niedriger als 0,5 WNiedriger StromverbrauchDer DAC3 verbraucht im Betrieb nur 12 W .HPA2™ Kopfhörerverstärker auf ReferenzniveauDer DAC 3 hat zwei Kopfhöreranschlüsse und einen Verstärker mit hoher Stromlieferfähigkeit und 0-Ohm Impedanz.

This sonic transparency is absolutely essential in the studio monitoring chain.Benchmark converters have become a standard fixture in many of the worlds finest studios.Bring the Studio into Your Living RoomWhen Benchmarks professional converters are used in hi-fi applications, studio-quality sound can be enjoyed in a home environment. Enjoy pure music without any coloration from the electronics. Hear the music exactly the way it was heard in the studio, and exactly the way the artists intended.Discover the natural, uncolored, analog sound of Benchmark converters.Sit in the Performance SpaceTransparent sound can go beyond replicating the studio experience. Recordings that have been produced with a natural and unprocessed sound can transport you to the performance space. Close your eyes and get ready to be transported!The experience of being there can only happen when the entire audio chain is selected for maximum transparency.Benchmark DAC3 Product FamilyEach member of the DAC3 converter family is sonically identical, and they share identical performance specifications. Each model is built on the same circuit board, but the higher-priced models add additional features.DAC3 BDigital Inputs OnlyNo Volume ControlIdeal for use with a separate preamplifier such as the LA4 or HPA4Excellent choice for professional studio applicationsThe DAC3 B to HPA4 to AHB2 signal chain is our flagship HiFi system.The DAC3 B to LA4 to AHB2 signal chain provides the same performance when a headphone amplifier is not needed.DAC3 LIncludes all of the features found on the DAC3 BAdds our Hybrid Gain Control (combined analog and digital volume control)Adds two pairs of unbalanced inputsExcellent choice when the DAC will act as the system volume control.The DAC3 L to AHB2 signal chain is our second-best signal chain.An LA4 or HPA4 can be added to the chain to raise the performance to that of our flagship system.Volume control is bypassed when an LA4 or HPA4 is addedDAC3 HGCIncludes all of the features found on the DAC3 B and DAC3 LAdds our HPA2™ headphone amplifier.An LA4 or HPA4 can be added to the chain to upgrade the performance to the top tier.Volume control is bypassed when an LA4 or HPA4 is added DAC3 TechnologiesHarmonic CompensationHybrid Gain ControlUltraLock3™ Jitter Attenuation SystemHigh-Headroom DSPMulti-Mode Asynchronous USB Audio SystemQuad 32-bit balanced D/A Conversion SystemDistributed Power RegulationHarmonic CompensationThe ES9028PRO has two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter. Benchmarks ultra-clean analog output stages allow these systems to be fully leveraged in the DAC3. To the best of our knowledge, no other D/A converter has lower THD than the Benchmark DAC3.Hybrid Gain ControlHGC is Benchmarks unique Hybrid Gain Control system. The DAC3 combines active analog gain control, passive low-impedance attenuators, a 32-bit digital gain control, and a servo-driven volume control. All inputs are controlled by the rotary volume control. This volume control moves in response to commands from the remote control. Analog inputs are never converted to digital, and digital inputs never pass through an analog potentiometer. Digital inputs are precisely controlled in the 32-bit DSP system. The DSP system preserves precise L/R balance, and precise stereo imaging, while avoiding any source of noise and distortion.Benchmarks unique passive output attenuators provide distortion-free gain reduction without reducing the dynamic range of the converter. The attenuators optimize the gain staging between the DAC3 and the power amplifier. This optimization is absolutely essential for maximizing the dynamic range of the entire playback system. Much of the success of the DAC1 and DAC2 converters can be attributed to the passive output attenuators. Musical details can be obscured by system noise whenever a preamplifier and power amplifier are improperly matched. The HGC system will make full use of your power amplifiers dynamic range. Experience new details in your favorite recordings.UltraLock3™ Jitter Attenuation SystemUltraLock3™ is an improved version of the UltraLock2™ system used in the DAC2 product family. UltraLock3™ locks with precise phase accuracy in only 6 ms. In contrast, the UltraLock2™ system required 400 ms. Both UltraLock™ systems provide virtually perfect jitter attenuation, but the lightning-fast lock time of the new UltraLock3™ will be appreciated by many of our users.DSP processing is 32-bits, DSP headroom is 3 dB, sample rate is 211 kHz, and jitter-induced distortion and noise is at least 140 dB below the level of the music - well below the threshold of hearing. Benchmarks UltraLock3™ system eliminates all audible jitter artifacts.High Headroom DSP - with 3.5 dB Excess Digital HeadroomAll of the digital processing in the DAC3 is designed to handle signals as high as +3.5 dBFS. Most digital systems clip signals that exceed 0 dBFS. The 0 dBFS limitation seems reasonable, as 0 dBFS is the highest sinusoidal signal level that can be represented in a digital system. However, a detailed investigation of the mathematics of PCM digital systems will reveal that inter-sample peaks may reach +3.01 dBFS while individual samples never exceed 0 dBFS. These inter-sample peaks are common in commercial releases, and are of no consequence in a PCM system until they reach an interpolation process. But, for a variety of reasons, virtually all audio D/A converters use an interpolation process. The interpolation process is absolutely necessary to achieve 24-bit state-of-the art conversion performance. Unfortunately, inter-sample peaks exceeding 0 dBFS cause clipping in most interpolators. This clipping produces distortion products that are non-harmonic and non-musical . We believe these broadband distortion products often add a harshness or false high-frequency sparkle to digital reproduction. The DAC3 avoids these problems by maintaining at least 3.5 dB of headroom in the entire conversion system. We believe this added headroom is a groundbreaking improvement.Multi-Mode Asynchronous USB SystemBenchmarks USB system supports USB Audio 2.0, DSD, and USB Audio 1.1. It is frequency agile, and will follow sample rate changes initiated by the computer and/or the media playback software. In all modes the USB communications are asynchronous in order to eliminate unnecessary sources of jitter.The DAC3 has a low-jitter master clock which controls the transfer of audio data from the computer to the USB sub-system. The computer asynchronously transfers audio data to a buffer in the DAC3. The contents of the buffer are then asynchronously transferred to the D/A conversion subsystem. This second asynchronous transfer eliminates any traces of jitter that accumulate as the data is transferred between the USB and conversion subsystems. No traces of jitter-induced distortion are measurable to our measurement limits (better than -150 dBFS). This truly represents the state-of-the art. Enjoy the convenience of computer playback without compromise. The Asynchronous USB system supports USB Audio 2.0 for high-resolution 192kHz, and DSD playback. No drivers are required for MAC operating systems. An easy-to-install driver adds 192 kHz and DSD capabilities to Windows operating systems.An asynchronous, driverless USB Audio 1.1 mode supports sample rates up to 96 kHz. This USB mode can be selected from the front panel or from the remote control. The driverless USB Audio 1.1 mode allows quick plug-and-play connections to Windows, MAC, iOS, and Linux operating systems without installing drivers. Just plug in the USB, and the DAC3 becomes an available audio device.The USB subsystem remains active when the DAC3 is powered down. This prevents interruptions to the computer playback operations and eliminates the need to reconfigure the computer every time the converter is turned on.Quad 32-bit Balanced Conversion SystemFour balanced 32-bit D/A converters deliver audio to Benchmarks low-impedance current to voltage converters. The 4:1 redundancy reduces noise and distortion to levels that set new benchmarks. The conversion system at the core of the DAC3 is as good as it gets. The analog circuits that follow the D/A converter are carefully designed. Benchmark has leveraged its long history of building high-end analog audio equipment, in order to create an outstanding output stage.The conversion system in the DAC3 achieves a 6 dB signal to noise improvement through the use of 4:1 summing. The ES9028PRO D/A is an 8-channel 32-bit converter. In the DAC3, four channels are summed in the analog domain to form each of the two output channels.The 4:1 summing also improves the THD. The non-linearities in individual conversion channels are averaged across the four summed channels and incoherent non-linearities are attenuated by 6 dB.Diagnostic Tools - Sample-Rate and Word-Length IndicatorsEver wonder why that 192 kHz 24-bit download on your computer just doesnt sound right? Your media player may be down-sampling to 44.1 kHz and/or truncating to 16-bits. Many computers and media players apply poor-quality sample rate conversion and truncation. Fortunately these problems can be eliminated with the selection a good frequency-agile media player. The sample-rate and word-length displays on the DAC3 confirm the proper operation of your media player.Polarity SwitchYou may encounter recordings with inverted polarity. The DAC3 HGC and DAC3 L include a polarity switch to correct the problem.Home Theater BypassThe DAC3 can be integrated into a home theater system. Typically the DAC3 drives the left and right power amplifiers, and an analog feed from the home theater system is connected to either of the analog inputs on the DAC3. A programmable Home Theater Bypass function sets the pass-through gain to unity when the surround system is active. The DAC3 HGC and DAC3 L include an indicator light that is illuminated when bypass is active.Digital Pass ThroughThe second coaxial input on the DAC3 can be reconfigured as a digital output. In output mode, any selected digital input (including USB) will pass through to the coaxial output. The digital pass through is bit-transparent and even supports DSD (DoP 1.1). Dolby digital and DTS formats can also be passed through to a surround processor.Bi-Directional 12 Volt TriggerBenchmark re-invents the 12 volt trigger. The trigger connection on the DAC2 can be used as an input, an output, or both. It is compatible with any common 12 volt trigger input or output. The trigger can be used to turn a power amplifier on or off automatically. The DAC3 will also respond to a 12 volt trigger to follow the actions of another audio component.Power SwitchThe power switch can place the DAC3 in standby, or full shut down. In full shut down, the unit will still respond to the trigger input and the IR remote control. Power consumption is less than 0.5 W in full shut down.Low Power ConsumptionThe DAC3 uses high-efficiency low noise power supplies and may be operated from any standard international voltage without adjustment. Power consumption is 12 W typical.Distributed Power RegulationTo achieve the lowest possible noise, the DAC3 uses distributed power supply regulation. Each critical subsystem has at least one dedicated low-noise voltage regulator.HPA2™ Headphone Power AmplifierThe DAC3 features the HPA2™ - Benchmarks signature high-current, 0-Ohm headphone power amplifier. The HPA2™ is arguably the ultimate reference headphone power amplifier. It will deliver the full rated performance of the DAC3 to the headphones. The DAC3 has two 1/4 headphone jacks on the front panel. The performance of the HPA2™ remains consistent even when two headphones are being driven simultaneously.
