Meridien Serial Digital I/O Board

Audio Boards in the Meridien I/O Box

Two-channel
audio board
The SDI board provides physical inputs and outputs between the
video I/O board and a serial digital device. The board also contains
the circuitry for the Consumer Source button on the Video Input tool.
There are two different audio boards used to interface the IBM 6868
system to speakers and video decks depending upon the type of
system you order. Both boards are standalone boards and are not
attached to the video I/O board.
Eight-Channel Audio Interface Board
An optional eight-channel audio interface board (see Figure 2-4) links
the system to a separate eight-channel audio I/O device (Digidesign
888 I/O). The audio I/O device provides connections for up to eight
channels of digital audio or eight channels of analog audio.
Two-Channel Audio I/O Board
A two-channel audio I/O board (see Figure 2-5), normally used with
the Avid Xpress systems, provides connections for two channels of
digital audio, two channels of analog audio, and a microphone input.
