So you've got your entire audio system running Digital (Coax or Toslink) audio, but you've got one old piece of equipment with analog output that is gumming up the works? No problem! Just get the Monoprice Analog to Digital Audio Converter and bring your old equipment into the digital age! This compact little converter has a set of right/left RCA analog audio input jacks. It will simultaneously convert the analog audio into Coax and Optical (Toslink) Digital signals. You can connect either or both outputs to an appropriate digital audio input on a TV, AV receiver, or anything else. The converter has a digital sampling rate of 48 kHz and produces an LPCM stereo audio output signal. It is powered by a 5V DC power adapter, which is included. All the connectors are gold-plated. Note that this converter only works one way - Analog to Digital. It will NOT convert digital signals to analog! Monoprice has all the cables you need to use this converter!
