Stereo/Octophonic digital-analogue converter

Ongoing project

I am working on creating a digital-analogue converter (DAC) with the ability to output up to 8 channels of audio. I wanted the ability to fully appreciate the many multi-channel classical music recordings I own and was inspired to build my own DAC after finding that 8-channel retail DACs are prohibitively expensive. The DAC will be housed in a Hi-Fi 2000 Slim line 2U case with 10mm thick aluminum front panel and a custom design.

Specifications

  • Digital inputs via USB, AES/EBU, S/PDIF and TOSLINK
  • Up to 8 channel outputs via XLR or RCA connectors
  • 120/240 VAC filtered power input
  • Digital LCD display and input switching
  • 1/4" TRS headphone output on front

Technology

2- to 8-channel switcher
