FEATURES:• 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
• 32 mono channels
• 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
• Dual Stereo Channels
The GL4000 can be ordered with 0, 4 or 8 stereo input channels with dual inputs: XLR mic/line with insert and stereo (TRS) jack with width control, polarity reverse on right input signal and stereo PFL. A direct to L-R button routes the stereo line-in to the mix buss, allowing the channel to be used on the XLR input alone if desired. Either source can use the main channel with 4 band EQ and 10 auxiliary sends
• 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
