DIGITAL TRIM
• Pressing the DIGITAL TRIM button assigns
the channel V-Pots to become digital trim
(digital input level) controls.
• Functionally located immediately after the A/D
converter in the signal path for channels 1–48.
• When using digital I/O cards, for channels
25–48, there is no A/D converter, so the digi-
tal trim is simply the first control in the signal
path after the card.
• Digital Trim is a recallable function, unlike
the analog Trim control. It can be automated
or stored in a snapshot.
• Digital Trim is the only input trim control for
channel inputs 25–48.
Talkback Mic
• Located just above the LEVEL TO TAPE and
DIGITAL TRIM buttons.
