Helix C FOUR
Helix C series amplifiers are pure HighEnd. The class A preamp feeds hand-selected Mosfet transistors, of which there are 32 in this 4-channel amplifier. The damping factor is over 1000, with this amplifier the cone of any speaker remains perfectly under control. The regulated power supply keeps the power the same regardless of the car system voltage in the operating range of 9-16 volts. The Start&Stop compatible terminal stays on even at a voltage of 6 volts so that the music does not stop even at traffic lights.
The optional HDM (Helix Digital input Module) module allows you to input audio directly into the amplifier digitally.
Specifications:
- 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 configuration
- Microprocessor-based monitoring of amplifier 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 HDMI2 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
