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.
• The Talkback mic is activated two different
ways: 1) by pressing Talkback in the Control
Room section, 2) by pressing a foot pedal con-
nected to the Talkback jack in the rear of the
console.
• Talkback audio is sent to the Phones/Cue
Mixes when pressing Talkback or depressing
the foot pedal, or to the Studio monitor system
when pressing Talkback to Studio.
Left/Right LED Ladders (Master Meters)
• Located above the Talkback Mic.
• Indicates the signal level of whatever is se-
lected in the Control Room section.
• When Solo is selected, the Master Meters indi-
cate the level of the combined soloed channels.
• When Mono is selected in the Control Room
section, both Left and Right meters indicate
the mono level.
