Mono Input
The MIC GAIN control (1) adjusts the sensitivity of both mic (XLR) and Line (1/
4” jack) inputs. Both inputs are electronically balanced, and are located on the
rear connector panel.
The PEAK LED (2) monitors two points in the audio path: pre-insert point and
post-EQ.
The 48V switch (3) applies 48V phantom power to the input XLR. An
adjacent 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 (4) reverses the phase of the input.
The HI-PASS switch (5) enables the high-pass filter.
The module insert point is pre-EQ, pre-fader. It is located on the rear connector
panel.
The EQ section (6) is four band, with shelving HF and LF, and swept peaking
high and low mid sections.
The HF and LF sections give +/-15dB cut/boost at 13kHz and 60Hz respec-
tively. The Lo-mid section gives +/-15dB cut/boost at 80Hz-1.9kHz. The Hi-mid
section gives +/-15dB cut/boost at 550Hz-13kHz.
The section is switched in by the EQ switch (7).
The signal in the module is turned on and off by the MUTE switch (8). An
adjacent LED illuminates when the module is muted. All outputs from the mod-
ule are muted, except for the Direct Output if its Pre button is depressed. The
PFL will still work whilst the module is muted.
Signal is sent to the AUX 1-6 busses via individual level pots (9). Aux 1 and 2
are both post-eq* pre-fade feeds. Aux 3 and 4 are jointly selectable, via the
PRE switch (10) 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 selected 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.
Post-fader signal level is controlled by a 100mm fader (11).
Signal for the mix and sub (sub applies to GB2R12-2 only) busses are routed
via the PAN pot (12). The pan pot positions the signal within the stereo image.
The signal can be sent to the stereo mix busses (13) and/or sub busses (14 -
GB2R12-2 only). Note that the sub busses are a stereo pair.
Note for GB2R 16 only. At first sight, being able to de-select the feed
to the mix busses (13) may seem pointless, but it allows the user to
route signal to the aux busses, and/or to use the Direct Outputs
post-fade, without routing to the main mix.
A signal LED (15), next to the fader, meters the post-EQ, pre-mute signal.
The PFL switch (16) feeds the pre-mute signal to the monitor outputs and
phones output. An adjacent LED indicates when the PFL is on.
