Stereo Input - GB2R 12-2 only

MIC GAIN (1) adjusts the sensitivity of the stereo pair of mix XLR inputs. They are
electronically balanced, and are located on the rear connector panel.
The 48V switch (2) applies 48V phantom power to the input XLRs. An adja-
cent LED indicates when the phantom power is on.
Don't connect microphones with the phantom power switched on. Only
switch the phantom power on or off with the output fader down.
The PHASE switch (3) inverts the phase of the left channel XLR.
The LINE level control (4) adjusts the signal level from the stereo pair of line input 1/
4" jacks on the rear connector panel. The line inputs are balanced.
The LINE TO MIX/LINE TO CHAN (5) switch works as follows:
When the switch is in the raised position (LINE TO MIX) the signals from the
line inputs are routed (via the line level control) directly to the main mix l &
r busses. The XLR mic inputs are routed through the channel. This, in effect,
gives an extra stereo return input.
When the switch is in the depressed position (LINE TO CHAN) the signals
from the line inputs are routed through the channel. The mic XLR inputs are
not used.
The L switch (6) routes the left input signal to both L and R channels in the module.
The R switch similarly routes the right input signal. Pressing L and R together mono
sums the input.
The PEAK LED (7), monitors both left and right signals pre-EQ.
The EQ section (8) has four bands, with shelving high and low frequencies and peak-
ing high-mid and low-mid bands.
The HF control gives +/-15dB cut/boost at 13KHz. The LF control gives +/-15dB cut/
boost at 60Hz. The HM control gives +/-15dB cut/boost at a centre frequency of
2.5kHz, and the LM control gives +/-15dB cut/boost at a centre frequency of 450Hz.
The EQ is switched in by the EQ switch (9).
The stereo signal in the module is turned on and off by the MUTE switch (10). An
adjacent LED illuminates when the module is muted. The PFL will still work whilst the
module is muted. The Line To Mix routing [see (5) above] is not affected by the MUTE
switch.
A mono sum of the signal is sent to the AUX 1-6 busses via individual level pots (11).
Aux 1 and 2 are both post-eq* pre-fade feeds. Aux 3 and 4 are jointly selectable, via
the PRE switch (12) to be pre-fade* or post-fade feeds. Aux 5 and 6 are post-fade
feeds*.
* Note: there is a dealer-implemented option to connect aux 1 and 2 feeds
as pre-eq pre fade. This would also affect aux 3 and 4 when they are se-
lected as pre-fade.
Aux 5 and 6 may be connected to follow aux3/aux4 pre/post routing.
The warranty is voided if these options are implemented by anyone other
than an Authorised Soundcraft Dealer.
The BAL control (13) allows the stereo image to be balanced between the left and
right channels within the module.
Post-fader signal level is controlled by a 100mm stereo fader (14).
The signal can be sent to the stereo mix busses (15) and sub busses (16). Note the
sub busses are a stereo pair.
A signal LED (17), next to the fader, meters the post-EQ, pre-mute signal.
The PFL switch (18) feeds a mono sum of the pre-mute signal to the monitor output
and phones output. An adjacent LED indicates when the PFL is on.
