Item Description The DAC1 is a two-channel, 24-bit, 192-kHz Digital-to-Analog audio converter. It is, perhaps, one of the more significant recent advances in digital-audio conversion technology. Listening to audio from the DAC1 is an absolutely truthful experience. The distortion free output is so pristine you can now hear detail which was previously masked by jitter induced artifacts and distortion. If the recording was exceptional, you’ll hear it; if it wasn’t, you’ll hear that as well. The DAC1 is a 192-kHz converter, and will playback 192-kHz signals with a 52-kHz analog bandwidth. THD+N is an astonishing low -105 dB (0.00056%) measured at 0 dBFS, and -107 dB measured at -3 dBFS – at any playback frequency, at any sample rate, and with any degree of input jitter. The secret? UltraLock™ technology. Additional features include: phase-coherence between units, auto-detection and processing of pre-emphasized digital audio, and an ultrahigh performance HPA-2 headphone amplifier with dual outputs. The DAC1 has an internal, international toroidal power supply. The front panel level-control always adjusts the headphone output level. The front panel level-control can also be selected to adjust the output levels at the rear of the converter. Alternately, the output levels can be set at a fixed gain with precision, rear panel; 10-turn trim pots. The balanced output level range is +10 dBu to +29 dBu at 0 dBFS. The DAC1 is essential equipment for mastering and recording studios, broadcast facilities, even audiophile home stereo installations, and all locations that require uncolored monitoring.

Benchmark DAC 1 Pre combination pre amp headphone amp and 24 bit 192 khz digital to analog converter. Please note the USB input is limited to 24bit 96khz. Features fixed or variable analog unbalanced RCA and balanced XLR outputs as well as two 1/4 inch headphone jacks. Inputs include USB 2.0, optical toslink, 3 coaxial digital, and one pair of analog stereo RCA connectors. The front volume control is a fully analog high quality Alps brand. The headphones outputs are always variable while the rear balanced XLR and unbalance RCA outputs are selectable as fixed or variable. The versatility of the Benchmark is truly great. I used it in both a headphone setup and in my main home stereo system with excellent results. This is a Stereophile Class A recommend component as are each of its offspring. It offers a highly detailed and layered sound that competes well above its price point. Of all the Benchmark DAC 1 options. The PRE and HDR offer the most versatility and were the last versions of the DAC1 before being replaced by the DAC2. The HDR simply offers a remote control which the PRE does not. This unit is in excellent condition overall with no scratches or dings anywhere on it. The only thing I see that keeps it from being mint is the n in the analog input lettering is partially missing (see photos). Everything functions as it should and it sounds excellent. The original power cord is included. There is no documentation or original packaging but it will be securely packaged for shipping. I will accept offers above my initial listing price if you wish to purchase this before any bids are placed. Once a bid is placed this option will disappear. Please check my feedback and purchase with confidence. Thank you for your interest.

NOT USB MODELThis is the model without rack ears. Includes original box. paperwork/manual, power cord and BNC/RCA adapter.Benchmark DAC1The DAC1 is a reference-quality, 2-channel 192-kHz 24-bit audio digital-to-analog converter featuring Benchmark’s UltraLock™ technology. The DAC1 is designed for maximum transparency and is well suited for critical playback in studio control rooms and in mastering rooms. A compact and rugged enclosure makes the DAC1 an excellent choice for location recording, broadcast facilities, and mobile trucks.Made in the USABenchmark products are designed and manufactured in the USA.An Industry StandardBenchmarks award-winning DAC1 has become a standard in the finest recording studios and mastering rooms. Audio engineers rely of the accurate, uncolored, and precise sound of Benchmark DAC1 converters. The DAC1 is free from digital artifacts and its analog sound eliminates the fatigue that is caused by many digital devices. Audiophiles have also discovered the smooth and detailed sound of the DAC1, and it has become a centerpiece in may home listening rooms.International Power SupplyThe large internal power supply supports all international voltages and has generous margins for over and under voltage conditions. The power supply is sized to supply the demands of the HPA2™ headphone power amplifier when driving two sets of headphones.Calibrated or Variable Output LevelsThe front-panel gain control sets the output level of the headphone jacks. It can also be used to control the output level of the balanced XLR and unbalanced RCA analog outputs. A rear-panel switch selects Variable or Calibrated output levels. In the Calibrated setting, the rear-panel outputs are controlled by multi-turn calibration pots.Direct Interface to Power AmplifiersAll Benchmark DAC1 and DAC2 converters are designed to directly interface with power amplifiers and powered monitors. The XLR outputs are equipped with Benchmarks exclusive low-impedance passive output attenuators. These attenuators can be set in 10 dB steps to optimize the gain-staging between the DAC and the power amplifier. This important feature maximizes the signal to noise ratio of the entire playback system.Jitter-Immune UltraLock™Digital interconnect cables, electro-magnetic interference, and many other variables introduce jitter into the digital audio. Jitter presents a major problem to most D-to-A converters. Jitter is a type of clock error that, if not properly addressed, can cause the D-to-A to misfire. The result of these misfires is a non-musical, digital distortion.Many modern (and expensive) converters suffer from severe jitter-induced distortion. Jitter is NOT a problem for the DAC1, which achieves jitter immunity by utilizing Benchmarks proprietary UltraLock™ clock-recovery system.With the UltraLock™ clock-recovery system, the digital-to-analog conversion-clock in the DAC1 is totally isolated from the clock of the digital audio input. This clock-recovery topology outperforms even the most well-designed two-stage PLL designs. Using state-of-the-art Audio Precision testing equipment, no jitter-induced artifacts can be detected with the DAC1. Any signal that can be decoded by the AES/EBU receivers will be reproduced without the addition of any measurable jitter artifacts. The bottom line is this: Benchmark converters will consistently and faithfully deliver truthful audio with no jitter-induced artifacts, no matter what variables are present.

Benchmark DAC1 HDR Digital to Analog converter with Benchmark Remote control. This DAC is also a source selector and motorized volume control, replacing audio preamps or souce selectors in a high end audio system. The Benchmark is a studio reference piece with a lower noise floor and higher dynamic range than most of the consumer grade DACs. The Benchmark is in a different class than consumer products. in terms of jitter, digital artifact rejection, and analog conversion.I ran my CD player and digital streaming device connected digitally to the DAC1 HDR and switched sources using the DAC, eliminating my preamp. It even has an analog input for your tape deck or phono preamp. This DAC1 HDR is in excellent condition and probably one step away from being mint. This was nearly $2200 new.https://benchmarkmedia.com/collections/discontinued-products/products/benchmark-dac1-hdr-digital-to-analog-audio-converter Ships to the USA lower 48 states only and will require a delivery signature.
