HELIX C FOUR- 4 channel SOUND QUALITY AMPLIFIER-HIGHEND BY AUDIOTECH FISCHER

Description: HELIX C FOUR 4 CHANNEL AMPLIFIERABSOLUTE AUDIOPHILE SOUND QUALITY BY AUDIOTECH FISCHERMADE IN GERMANY HERE IS YOUR CHANCE TO TRY THE AUDIOPHILE SOUND QUALITY, THIS AMPLIFIER PRODUCES AT A FRACTION OF PRICE. USED FOR A YEAR AND IN GREAT WORKING CONDITION TECHNICALLY. AMPLIFIER IS QUITE CLEAN AND ALL CONTROLS WORKS GREAT. UNFORTUNATELLY DUE TO MISHANDLING THE PLEXIGLASS HAS SOME LIGHT CRACKS WHICH ARE VERY COMMON WITH THESE AMPLIFIER DUE TO HOLDING THE AMPLIFIER FROM PLEXIGLASS RESULTS IN THIS SCENARION.THE PLEXIGLASS CAN BE ORDERED DIRECTLY FROM AUDIOTECH FISCHER DIRECTLY. @ 4 Ohms4 x 150 Watts- @ 2 Ohms4 x 220 Watts- @ 1 Ohm- - bridged @ 4 Ohms2 x 440 WattsMADE IN GERMANY HELIX C FOURAudiophile sound quality combined with impressive output powerThe C FOUR is a high-end 4-channel amplifier that has been designed down to the last detail for ultimate sound quality. Audiotec Fischer’s proprietary ultra low-noise and ultra low-distortion Class A driver stage feeds a total of 32 hand-selected MOSFET power transistors, resulting in an incredible damping factor of 1,000 for relentless control of every loudspeaker. The intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power independent of the cars battery voltage.In combination with the optionally available digital input module HDM 2, the C FOUR demonstrates the perfect transition to the digital era. The HDM 2 accepts digital audio signals up to 96 kHz sampling rate via its two optical inputs followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C FOUR is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.FeaturesExtremely broadband Class AB amplifier with eight selected MOSFET transistors per channel for exceptional sound quality - ideal for High-Resolution audioUltra low-noise and distortion-free power amp drivers in Class A technologyEnormous damping factor of 1,000 @ 4 Ohms for perfect speaker controlOptionally available HELIX Digital Input Module (HDM) to extend the amplifier with two optical digital inputs in SPDIF formatIntegrated, active crossover with highpass, lowpass and bandpassRegulated DC / DC switching power supply with Start-Stop capability down to 6V supply voltageMicroprocessor-based monitoring of amplifier status including temperature-dependent fan controlInput Mode switch for flexible routing of the input signalsCutting-edge BurrBrown D/A converters with 32 Bit resolution in combination with the optional HDM 2 moduleMassive 24-carat gold-plated power and speaker terminalsQuad-layer PCB with extra-solid 70μ copper traces for lowest possible losses and SMD (Surface Mounted Device) manufacturing technology Special features:Start-Stop capabilityThe switched power supply of the HELIX C FOUR assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.High-Resolution audioThe extremely broadband audio bandwidth of the amplifier ensures a lossless audio reproduction of High-Resolution audio content to provide the best possible sound in studio quality.Technical dataOutput power RMS ≤ 1% THD+N - @ 4 Ohms4 x 150 Watts- @ 2 Ohms4 x 220 Watts- @ 1 Ohm- - bridged @ 4 Ohms2 x 440 Watts- bridged @ 2 Ohms- Max. output power per channel*Up to 250 Watts RMS @ 2 OhmsAmplifier technologyClass ABInputs4 x RCA / Cinch1 x Remote InOptional via HDM 2 module:2 x Optical SPDIF (28 - 96 kHz)Input sensitivityRCA / Cinch 1 - 8 VoltsInput impedance RCA / Cinch7.5 kOhmsInput impedance highlevel- Outputs4 x Speaker outputOutput voltage RCA / Cinch- Signal converter for digital input- Frequency response10 Hz - 80,000 HzBass boost- Highpass15 Hz - 4,000 Hz adjustableLowpass15 Hz - 4,000 Hz adjustableBandpass15 Hz - 4,000 Hz adjustableSubsonic- Phase- Slope high- / lowpass12 dB/Oct.Slope subsonic / lowpass- Signal-to-noise ratio digital input- Signal-to-noise ratio analog input112 dB (A-weighted)Distortion (THD)< 0.007 %Damping factor> 1000Operating voltage9 - 16 Volts (max. 5 sec. down to 6 Volts)Idle current2400 mAOperating temperature range-40° C to +70° CFuse3 x 30 A LP-Mini-fuse (APS)Additional featuresActive, adjustable crossover, HDM slot, input mode switch, High-Resolution audio, Start-Stop capabilityDimensions (H x W x D)37.1 x 430 x 240 mm /1.46 x 16.93 x 9.45"
