All mono channels (2 stereo returns above the masters).

Dual Functionality
GRP/Aux Mode switches reverse aux master section with the group faders giving up to 8 monitor sends with inserts on 100mm faders. Another under panel switch converts the Mono control and XLR output to an engineer's listen wedge output

Frames Available
16, 24, 32, 40 channels available. A, B, C & D versions of each frame size provide choice of stereo configurations: A: all mono; B: 4 stereo to the right of master section; C: 4 stereo on outside right; D: 8 stereo to right of master section

8 Audio Groups
Assignable from paired routing buttons and pan from channels. Groups access LR busses via a pan control. Groups 5-8 have XLR outputs, 1-4 are to the mix only. All have inserts.
Optional 25-way D connector on rear panel can provide +4dBu outputs for all groups for recording purposes

8 Auxiliary Sends
8 auxiliary switchable pre/post fade in blocks: 1-4, 5-8. Aux masters are rotary controls. Auxes 1-4 have inserts and XLR outputs.
Auxes 5-8 have (TRS) outputs for FX sends; these provide XLR outputs with inserts when the GRP/Aux reverse switches are pressed

12 x 2 Matrix
2 matrix outputs (A & B) are fed from the groups and the LR busses and the stereo returns. They are controlled by 60mm faders, have AFL and are connected to the groups regardless of GRP/Aux mode. There is a balanced output option

4 Mute Groups
4 selector switches on input channels assign the mute groups. These are controlled by 4 large illuminated master mute buttons

4 Band EQ plus HPF
Seperate controls for sweep and cut/boost on mid bands. HPF @ 100Hz is switchable

Stereo Channels
The GL3300 can be ordered with 0, 4, or 8 stereo input channels. Mic or line source on either 2 XLRs or 2 TRS jacks with 20dB pad/sensitivity, separate gain and mono select controls for L & R, and 4-band EQ

2 Stereo Returns
TRS line inputs. 60mm fader control with pan & routing to group, L&R and the matrix

Engineer's Toolbox
Headphone and wedge monitor controls. 3 segment LED meters on input channels and 4 segment LEDs on GRP/Aux masters. 12 segment bar meter on L & R follows the PAFL system. Channels have direct outs (TRS) for recording.
2 track record/monitoring/replay. Talkback, with trim, possible to any of the 8 auxes

RPS11 300W 3U rack mounting power supply. RPSD2 1U dual supply combiner allows 2 PSUs to link up to the console for redundant supply backup, with monitoring

Configuration Options
Internal links to configure: individual aux sends as pre/post fader & pre EQ. Isolate pre-fade aux from channel mute. Pre-fade direct out. Mono out as pre-fade
