We originally set out to create a compact, flexible 8-group mixer on a 4-group budget. Once we’d met that seemingly impossible design brief, we even managed to include mute groups and a 12x2 matrix, giving you really serious control and output capability at a sensible cost.
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. With the press of a few switches it’s a thoroughbred monitor mixer with 8 aux mixes on 100mm faders. How’s that for bang for your buck?

We offer 4 versions so that customers can choose the one best suited.

A - All mono channels (2 stereo returns above the masters)
--------------------------------------------------------------------------------
B - 4 full stereo channels to right of masters
--------------------------------------------------------------------------------
C - 4 full stereos to extreme right
--------------------------------------------------------------------------------
D - 8 full stereos to right of masters
