• Ultra low-noise and distortion-free power amp drivers in Class A technology
• Enormous damping factor of 1,000 @ 4 Ohms for perfect speaker control
• Optionally available HELIX Digital Input Module (HDM) to extend the amplifier with two optical digital inputs in SPDIF format
• Integrated, active crossover with highpass, lowpass and bandpass
• Regulated DC / DC switching power supply with Start-Stop capability down to 6V supply voltage
• Microprocessor-based monitoring of amplifier status including temperature-dependent fan control
• 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 HDM 2 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 (Surface Mounted Device) manufacturing technology

Special features:

Start-Stop capability
The 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 audio
The 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.
