The GefenTV Digital Audio Translator is a compact and convenient coaxial/TOSLINK audio converter that accepts an audio signal input through either coaxial (S/PDIF) or optical (TOSLINK) cable. Both outputs pass digital audio simultaneously. The GefenTV Digital Audio Translator can also act as an audio repeater unit effectively doubling the digital audio distance. The input can be switched from S/PDIF to TOSLINK using the slide switch on the input side. Connect a digital audio source to the input on the device (TOSLINK or Coax.) Take a lead from either or both output ports to audio equipment (such as an amplifier) using coaxial or TOSLINK (fiber) cable. Power the unit with the 5VDC power supply included. When power is applied the red power LED will light up.
