About Audio Hardware
Avid systems includes the following three devices for sampling,
recording, and playing audio:
¥ Audio interface
¥ Pro Tools board
¥ Video Slave Driver
The audio interface, which is connected to the Pro Tools board, con-
verts analog or Audio Engineering Society/European Broadcast
Union (AES/EBU) digital audio (for example, audio from a videotape
or CD) to and from digital audio for the Pro Tools board.
The audio interface is connected to the Video Slave Driver and a black
burst generator reference signal which locks audio and video sam-
pling together to keep video and audio synchronized. The audio inter-
face is usually connected to an ampliÞer with speakers or a rack-
mountable speaker/ampliÞer unit for monitoring audio during
recording and playback.
Four-Channel Audio Interface
The standard four-channel audio interface has connectors for four
channels of analog audio input and four channels of output, which is
the maximum number of channels supported by Avid DNG systems.
Connectors are also provided for one input and one output channel of
AES/EBU digital audio.
