GL4000 21 buss live sound console 40 mic/XLR channels (no stereo channels except returns)
This mixer looks, feels and performs like a true workhorse. Like its siblings in the GL range, we built GL4000 to be equally at home in the front-of-house position or in monitor land. We also packed in a really serious set of live recording tools (someone always wants a tape of the show don't they?)
Although we've certainly been generous with the feature set, we were determined to make GL4000 really simple to use, so anyone with reasonable mixing skills should be able to use one to run a world-class show with a bit of practice. Our efforts have been rewarded by the sight of so many GL4000s succeeding in high-profile roles where you'd normally expect to find something costing 10 times more.
Dual Functionality
GRP/Aux Mode switches reverse aux faders with the group and L&R faders giving up to 10 monitor sends with inserts on 100mm faders. A Centre Mode switch converts the 100mm C fader to engineer's listen wedge control with insert
8 Audio Groups
Assigned from paired routing buttons and pan from channels. Groups access LR & M busses and have XLR outputs with inserts. Groups have 4 segment led pre-fade meters and 12 segment, 3 colour peak reading meter access plus VU meters in meterbridge on outputs
10 Auxiliary Sends
10 auxiliaries switchable pre/post fade in blocks: 1-4, 5-8, 9-10. Aux 10 can control the direct out. Aux masters have pre-fade metering, faders and mutes.
Auxes 1-4 have matrix link switches to allow groups, LR & M access to the aux buss. All auxes have inserts and XLR outputs and can be controlled by the main faders if desired
Left Right and Mono busses
Available from channels and groups. LR & M have 12 segment, 3 colour peak reading meter access plus VU meters in bridge. GL4000 also includes secondary L&R output with level and pre/post fader select on TRS jacks (can swap with the aux 9-10 XLR outs with inserts)
11x4 Matrix
Fed from the groups and the LR & M busses. Matrix outputs are on XLRs with inserts. Aux link switches feed the matrix into the aux buss for expanded sends from all the console sections
8 Mute Groups
8 master mute group buttons with single / multi mode and preview facility. Groups are edited ‘off-line’ and channels can be made ‘safe’. Input channels, auxes, groups, and LRM sections all have ‘soft’ mute buttons
4 Band EQ plus HPF
Separate controls for sweep and cut/boost on all sections. Mid bands have switchable Q. HPF is swept from off-20-400 Hz
Trim pots
The channel direct outputs and group outputs can be controlled by trim controls, selectable pre / post fader. ideal for recording applications
Balanced XLR & Inserts
Gold plated connectors and separate balanced send and return inserts [TRS] on channels, auxes, groups, and LRM busses
PAFL system
Stereo PFL with trim. Quicksolo (‘solo-in-place’) with last solo / mix toggle facility. Channels can be made solo ‘safe’
128 Mute Patches
Show control of 128 patch memories with midi interface and display. Patch recall can be manual or auto increment
Talkback
Talk to the groups, auxes, matrix and LRM outputs. +48V and trim control for mic
Engineer’s Toolbox
2 headphone, wedge and local monitor controls, - 20dB ‘dim’ when TB active. Stereo / mono selection, direct outs and groups can be ‘trimmed’ for recording
Lamps
2 XLR lamp sockets are provided
PSU
RPS11 300W 3U rack mounting supply. Optional RPSD2 1U dual supply combiner allows 2 PSU’s 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 and pre EQ. Isolate pre-fade aux from channel mute.
