HELIX HDM 2 - C FOUR

Do it digitally – ready for high-res audio

With the HELIX Digital Input Module (HDM) your HELIX amplifier accomplishes the perfect transition to the digital world.

It extends our amplifiers with an integrated HDM slot by two optical digital stereo inputs and enables completely interference-free and ground-isolated signal transmission in best possible quality right into the amplifier. The module can handle digital audio signals up to a sampling rate of 96 kHz losslessly via fiber optics cable and converts them back to the analog level via two cutting-edge BurrBrown DA converters.

But that's not all – in order to get the very last bit of performance out of the amplifier and avoid even the slightest influence of its input stage, the SPDIF Direct In function can be used to route the audio signal from the HDM module directly and without any detours to the output stages of the amplifier.

This makes your HELIX amplifier absolutely future-proof and perfectly equipped for the combination with our digital signal processors.

Features

  • Two optical digital inputs in SPDIF format inclusive SPDIF Direct In switches
  • SPDIF Direct In function allows to route the audio signals from the HDM module directly to the amplifier output stages for optimized sound performance
  • Cutting-edge BurrBrown DA converters with 32 Bit resolution
  • Accepts digital audio signals up to 96 kHz sample rate
  • Including device-specific side panel

Nice headlight. Minor wiring flaw.
Great looking lights. They come wired incorrectly. You will have to changes the pins around so the high beam and low beams come on when the switch is in the correct position. Or you can just have high beams on when the low is select and vice versa.

They look good but don't work properly
The headlights are bright no doubts about that. The fitment is not the greatest fits ok on one side but not the other side so good now for the most important part. The functionality is sketchy i spent hours trying to get the blinkers functioning correctly without any luck. Pretty cool looking but they have not worked out all the kinks
