Avid Technology DigiDesign PRE - Adjusting Input Gain; Muting Channels

Pro Tools | PRE Guide14
To change a setting with a channel control switch:
1 Select one or more channels.
2 Press a channel control switch to change its cur-
rent setting. For example, if the 48V LED is off,
pressing 48V will enable 48V phantom power
on all the selected channels. (48V can only be
enabled when input source is set for Mic input.
It is disabled as a choice when input source is
set for line or DI input.)
To return the selection to a single channel:
 Press Shift to disengage, then press the Select
switch of the individual channel you want to
edit.
Mixed State Operating Mode While Editing
Multiple Channels
A mixed state operating mode exists when you are
editing multiple channels simultaneously, and
some of the channels have different settings.
Channel Control Switches
When multiple channels are selected, switch mod-
ifications made to one selected channel are auto-
matically applied to all selected channels.
Gain/Param and Input Gain
If an offset exists between selected channels, the
offset will be maintained while moving the
Gain/Param control until you reach +69 dB gain
or 0 dB, at which point the selected channels will
mirror each other.
Adjusting Input Gain
To set input gain on a channel:
1 If the Gain/Param display currently shows a
MIDI channel, press MIDI. The display should
now show an input gain level.
2 Press the Select 1 switch (for example, for Mic
Input 1).
3 If the Source Mic LED is not lit, press Source
one or more times until the Mic LED is lit (so
that the Mic Input is active).
4 Rotate the Gain/Param control to change the in-
put gain level.
Muting Channels
To mute a channel:
 Press the Mute switch on each channel you want
to mute. To mute additional channels, press
their corresponding Mute switches. Meters re-
main active, and Channel Status controls can
still be changed.
To unmute a channel:
 Press Mute again.
Gain offsets are retained when multiple
channels are adjusted in Stand-alone mode,
but not in Pro Tools Remote mode.
To quickly mute all channels, drag your
finger across all the Mute switches.
