Two-Channel Audio I/O Boards
NewsCutter Release 2.x now supports four channels and eight tracks
of audio. The new two-channel audio I/O boards are now calibrated
for –20 dB as opposed to –14 dB in earlier releases. Avid provides two
new boards so that you do not have to recalibrate the original
two-channel audio I/O board. Each board provides connections for
two channels of digital audio, two channels of analog audio, and a
microphone input. Use the microphone input on the lower
two-channel audio I/O board. The top two-channel audio I/O board
slot is not configured for microphone input.
n
After removing the original two-channel audio I/O board from the system,
return the board to Avid. If you do not return the original (–14-dB)
two-channel audio I/O board within 30 days, you will be invoiced for the
value of the board.
To identify the difference between the –14-dB and the –20-dB boards,
the boards should be marked with the following part numbers:
• –14 dB — 0030-00283-01
• –20 dB — 0030-03074-01
If you are upgrading from NewsCutter XP, your kit includes a new
Meridien I/O box. The new Meridien I/O box already includes 2
two-channel audio I/O boards calibrated to –20 dB.
To replace a two-channel audio I/O board:
1. Turn off the Avid Meridien I/O box and remove the power cord.
2. Put on an antistatic wrist strap and connect it to a metal ground
point on your Meridien I/O box.

To avoid static damage to your circuit board, take the proper
antistatic precautions before handling the board. Often a wrist strap
is provided with upgrade kits.
