Audio BYPASS extension card

Audio BYPASS extension card

This small card is placed inside the computer and connected to Stream Alpha Plus PCI-E with a special cable, which sends the relay control signal. The card provides audio bypass mode synchronous with switching on/off the similar mode for pass-through video signal, ex. at computer power cutoff.

In this Stream ALPHA Plus PCI-E card operation design the sound is transmitted through standard computer Sound Blaster. There are plenty of sound cards on the market and it is not necessary to select the most advanced model. An on-board sound card can be also used. It is important however, that the sound card has only one Line In input.

If you intend to use TELE info with an external digital video stream source (except DV - IEEE-1394), make sure that the sound card does not have combined Line In and Mic In inputs.

Connector allocation:

  • Audio In: RCA x2 Line In (stereo)
  • Audio Out: RCA x2 Line Out (stereo)
  • Sound Card In: Phonejack Stereo, connects to computer sound card Line In
  • Sound Card Out: Phonejack Stereo, connects to computer sound card Line Out
