Adjusting Channel Controls
Most PRE parameters can be changed with front
panel channel control switches; for a descrip-
tion of each switch, see “PRE Front Panel” on
page 5. Input Gain is changed with the
Gain/Param control (see “Adjusting Input Gain”
on page 16).
PRE channel controls can be applied to one or
more channels at a time.
To select one channel:
 Press the Select switch of the desired channel.
Selecting one channel deselects the previously
selected channel or channels.
To select multiple channels:
 Hold Shift and press the Select switch of any
channels you want to adjust.
When more than one channel is selected, meter-
ing, control states, and Gain/Param settings
reflect the activity of the leftmost channel of the
group.
Adjustments made to any selected channel are
made to all selected channels. See “Mixed State
Operating Mode While Editing Multiple Chan-
nels” on page 15.
To change a setting with a channel control switch:
1 Select one or more channels.
2 Press a channel control switch to change its
current 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 set-
tings.
Channel Control Switches
When multiple channels are selected, switch
modifications made to one selected channel are
automatically 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 chan-
nels will mirror each other.
To quickly select all channels, drag your
finger across all the Select switches.
Gain offsets are retained when multiple
channels are adjusted in Stand-alone mode,
but not in Pro Tools Remote mode.
