Since then, the GL3300 has won us a lot of friends in hire companies and multi-purpose venues by performing so many jobs so well. It's a powerful, easy to use front of house console. B: 4 full stereo channels to right of masters.

FEATURES:
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.

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 auxiliaries 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

12x2 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
Separate 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 (except 16 channel version - see Frames Available above). 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.

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
