PREOWNED - $7500 LIST! - FULLY TESTED - SILVER - INCLUDES ORIGINAL BOX/PACKING, MANUAL POWER CABLE, SILVER/BLACK/RED DECORATIVE PANELSPerformer s1200The powerful stereo amplifierThis impressive stereo power amplifier leads even the mostdemanding speakers to soundscapes beyond your expectations. With a poweramplification of 2 x 520 W (4 ?) [2 x 550 W (2 ?); 2 x 300 W (8 ?)], thiscompletely analog amplifier easily controls any loudspeaker.Thanks to the VOLTAiR technology the performance of thes1200 is detail-rich, vivid, honest and plain simply beautiful.Individual designIn addition to the choice of the basic color black, red orsilver, there are three more options for each to customize the Performer s1200to individual design preferences with the black, red and silver decorativepanels included in the scope of delivery.The decorative panels adhere with the help of a strongneodymium magnet. No tools are required to exchange them.Better safe than sorryThe Performer s1200 has a protection circuit against DCvoltage and against overheating. If direct current (DC) is detected, theoutput stage switches off automatically and the Protect LED lights up red.To protect the s1200 against the unlikely event ofoverheating, a temperature sensor at the heatsinks continuously monitors thetemperature of the device. The TEMP LED lights up yellow when the Performers1200 is getting too hot. As a result of this the output stage is switched off and thefans run on high-speed until the device has cooled down.Freedom of choiceThe Performer s1200 features a stereo pair of XLR and RCAinputs. This makes it compatible with all preamps on the market without the useof adapters. The stereo input can be selected via the Input Select switch onthe rear panel.Trim to fitWith reference to the Performer s1200, “fit” meansadapted. You can adapt the input sensitivity in 0.5 dB steps from 0dB to -5.5 dB. In contrast to a panorama potentiometer in a preamplifier, thistrim switch is the more audiophile solution. The optimal operating range of theloudspeakers and preamplifier can be perfectly adjusted this way.Power to the speakersThe loudspeaker binding posts can accommodate banana plugsas well as a stranded wire with a diameter of up to 4 mm. Thus, any common typeof speaker cable can be used. However, we do not recommend connecting a speakerwith less than 2 ohms impedance.Trigger meThe standby mode of the power amplifier can be switched onand off using the AMP CTL connection between a preamplifier such as theDirector Mk2.To do this, connect the 3.5 mm phone jacks with a cable with3.5 mm mono or stereo jack plugs. Thanks to its 12 V trigger input, third partypreamps can also switch the Performer s1200’s standby mode on and off.A class of its ownConventional solid-state power amplifiers tend to operate ina critical range of the built-in components – this results in unpleasantharmonical artifacts. Tube power amplifiers also distort at their limit buttheir characteristically behavior softens this roughness and harshness.Non the less this is a falsified representation of the soundimage. Thanks to VOLTAiR Technology, the Performer s1200 can process muchhigher levels without even coming near to a critical range. All componentsconstantly operate in the optimal range. The result is a very pleasant, naturaland relaxed sound experience. Enjoy your music in every detail and without anylistening fatigue.Full powerThe Performer s1200 features individual amplification stagesfor voltage and power amplification, which ensures a perfect operating of theclass-AB amplifier circuit.Thanks to each stage’s own negative feedback path, it isruled out that feedbacks from the loudspeaker are interacting with the inputstage – this way the SPL VOLTAiR Technology can play out its full performance.Keep coolInside the Performer s1200, six fans usually do nothing atall, because 90 % of the heat is passively dissipated via massive heat sinks.Should it nevertheless become really loud for a really longtime, the processor-controlled fans remain virtually inaudible at only 19 dB(A).During power-up, the fans of the Performer s1200 brieflyrotate at a higher speed to remove dust of themselves and surroundingcomponents.Sounds goodWith all devices of the Professional Fidelity series wedevelop not only according to plan, but also by ear. Many important componentsare installed on the circuit boards using Through-hole technology. This way wecan ensure that we can use the best sounding components.The VOLTAiR TechnologyThe 120V technology is our reference technology. The 120Vtechnology is unique in the world. It operates at a DC voltage of 120 volts.This is four times that of IC-based semiconductor op-amps. In our ProfessionalFidelity series, we refer to this unsurpassed technology as VOLTAiR technology.The highest possible audio quality requires the highestpossible audio operating voltage.The 120V technology works with +/-60 V. To be able to handlesuch a high voltage, we have developed special proprietary operationalamplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRAoperational amplifiers. This high voltage would destroy conventional components andoperational amplifiers.By the way, the “120V” in the name of the technology hasnothing to do with the local mains voltage from the mains power socket. This isabout the operating voltage inside the device with which the audio signals areprocessed.The mains voltage from the mains power socket is transformed to the requiredsecondary voltage in the device’s internal linear power supply with toroidaltransformer. Rectifiers convert this AC voltage into DC voltage required in theaudio device.VOLTAiR is a composition of the terms Volt and Air. Volt isthe unit for electrical voltage and Air stands for theunlimited space the music can breathe in.VOLTAiR symbolizes the perceived limitlessdynamics resulting from high audio voltage.ComparisonMost audio devices work with an internal operating voltageof +/-15 volts and can thus process a maximum input level of +21.5 dBu. If aDAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of themusic material would already cause overloads in the input stage of thedevice. All components in the audio device often operate at theirlimits. The result is an unsteady sound that causes stress and faster earfatigue.SPL devices with VOLTAiR technology can handle input levelsof +32.5 dBu thanks to the higher internal operating voltage of +/- 60 volts –thus offering 12 dB more headroom. All components consequently operatecontinuously in the optimum operating range. The result is a very pleasant,natural and relaxed sound experience. So you can enjoy your music in everydetail.VOLTAiR is that goodIn the lab, we pitted Phonitor xe against the bestaudio measurement system and found that Audio Precision could not measureVOLTAiR technology.Home is where the heart isThat’s why we manufacture all SPL devices in our own productionfacility in Niederkrüchten on the Lower Rhine, Germany.SpecificationsAnalog Inputs: XLR (balanced), RCA (unbalanced)Input impedance20 k?Input trimming0 dB to -5.5 dB in 0.5 dB stepsInput sensitivity10,5 dBuLoudspeaker Outputs: Binding posts with 4 mm ø cable hole(screwable) and banana plugOutput power (RMS, 2 ?)2 x 550 WHarmonic distortion (1 kHz, 2 ?)< 0,09 %Output power (RMS, 4 ?)2 x 520 WHarmonic distortion (1 kHz, 4 ?)< 0,09 %Output power (RMS, 8 ?)2 x 300 WHarmonic distortion (1 kHz, 8 ?)< 0,04 %Output voltage (Peak-to-Peak)160 VOutput voltage (RMS)54,6 VOutput impedance (20 Hz – 20 kHz)< 0,031 ?Frequency range (-3dB)10 Hz – 80 kHzAmplification gain26 dBDamping factor (1 kHz, 8 ?)> 290Noise (A-weighted)-123 dBInternal Linear Power Supply with Shielded ToroidalTransformerToroidal transformer1440 VAOperating voltage (Input stage)+/- 60 VOperating voltage (power stage)+/- 80 VOperating voltage for relays, LEDs, AMP CTL+ 12 VMains Power SupplyMains voltage (selectable, see fuse chamber)230 V AC / 50; 115 V AC / 60 HzFuse 230 VT 6,3 AFuse 115 VT 10 APower consumptionmax. 1440 VAIdle power consumption50 WStand-by power consumption< 0,3 WDimensions & WeightW x H x D (width x height incl. feet x depth)278 x 205 x 375 mm10.94 x 8.07 x 14.76 inchUnit weight25,1 kg55,3 lbsShipping weight29,1 kg64,2 lbsReference: 0 dBu = 0,775V.
