Here you can edit the input channel parameters.
1
PAD
When editing online, this will indicate “MIC” if the rear panel PAD (34 dB) switch is off, or “LINE” if the switch is on. When
editing offline, this will indicate “MIC” by default.
2
+48V indicator
When editing online, this will be dark if the rear panel +48V switch is off, or lit red if the switch is on. When editing offline
this will be dark.
3
INPUT GAIN
This edits the input gain value. Click the [-]/[+] buttons, or make changes in the dialog box that appears when you click the
value.
The range will depend on the setting of the PAD (34 dB) switch.
4
-2 dBFS (PEAK), -38 dBFS indicators
If an input signal of -38 dBFS or higher is detected, the [-38 dBFS] indicator will light green.
If the [-2 dBFS] (PEAK) indicator lights red, the input signal has reached the maximum allowable level. If excessive input
level is indicated, either reduce the output level of the connected source, or reduce the input level via the appropriate rear-panel
[PAD] (34 dB) switch or by using INPUT GAIN.
NOTE
• dBFS stands for “decibels full scale,” and indicates the digital audio level. 0 dBFS is the maximum level.
5
[EQ] button
This button opens the “INPUT EQ” dialog box, where you can edit the EQ that is provided on each input channel. This is the
same as the BLOCK screen’s “INPUT EQ” dialog box; refer to
page 20
for details.
6
[F.B. SUP] button
This turns the feedback suppressor on/off (MONO INPUT channels only). The on/off state of this button is linked with the
Feedback Suppressor check box in the MISC screen. For more about the Feedback Suppressor, refer to
page 29
