Digital Audio Converters

Analog to Digital (ADC), and Digital to Analog (DAC) Audio Converters

Why, when and where do you need them?

  • You just purchased a new LCD or Plasma TV (Digital Output) and you need to get the sound through your Stereo System (Analog Input)? You need a DAC!

 • Your new digital speaker system (Digital Input) won’t work with your old stereo receiver (Analog Output) You need an ADC!

 • You have run out of digital inputs on your new home theater system and you want to connect your MP3 player that only has a digital audio output. You need a (DAC)!

What are these things?!

Digital to Analog Audio Converters (DAC's) convert either LPCM or Bitstream digital audio on Coax or Optical Toslink to Stereo Left/Right Audio.

Analog to Digital Audio Converters (ADC's) convert Stereo Left/Right analog audio into LPCM Digital Audio for either Coax or Optical Toslink Input.
