Helix C Series amplifiers are pure HighEnd. The Class A preamplifier is fed by hand-selected Mosfet transistors, of which there are 32 in this 4-channel amplifier. With an attenuation factor of over 1000, this amp keeps the cone of any speaker perfectly under control. A regulated power supply keeps the power constant regardless of the car's system voltage, with an operating range of 9-16 volts. The Start&Stop compatible terminal stays on at up to 6 volts so the music doesn't cut out at traffic lights.
The optional HDM ( Helix Digital Input Module ) module provides direct digital audio input to the amplifier.
- Regulated DC-/DC power supply with start-stop capability down to 6 volts supply voltage
- Ultra low-noise and ultra low-distortion driver stages in class A confi guration
- Microprocessor-based monitoring of amplifi er status including temperature-dependent fan
control
- Extremely stable output stages comprising eight hand-selected MOSFET transistors per channel
for exceptional sound quality & performance
- Integrated active crossover with highpass, lowpass and bandpass filters
- Input Mode switch for flexible routing of the input signals
- Cutting-edge BurrBrown D/A converters with 32 bit resolution in combination with the
optional HDM2 module
- Massive 24-carat gold-plated power and speaker terminals
- Quad-layer PCB with extra-solid 70μ copper traces for lowest possible losses and SMD
