Allen & Heath GL2800 overview

  • 1Description

The Allen & Heath GL series live sound reinforcement consoles exhibit the quality and detail synonymous with consoles that would render some live sound rigs over budget. The GL2800 is available in a 24, 32, 40, 48 and 56 input chassis to accommodate any mid-range sound reinforcement application.

The GL2800-32 is the 40 input version, complete with 40 line inputs, 40 microphone preamplifiers and 8-bus group routing. There is absolutely no shortage of routing possibilities with four dedicated stereo input channels, 10 auxiliary sends and a 12x4 routing Matrix section. Also featured are 1/4" phone TRS inserts on all input channels, auxiliary sends and stereo master output. Direct outputs via 1/4" phone connectors are provided on every input channel, enabling input signal to be routed directly to multitrack recorders, monitor mixers, etc.

Each input channel features a 4-band semi-parametric EQ, complete with In/Out switch. A HPF filter switch attenuates frequencies below 100Hz by 12dB per octave. The main output section consists of Left, Right and Mono outputs via balanced 3-pin male XLR connections. The combination of stereo and mono outputs allows the engineer to mix a stereo image while sending mono signals to subs or a separate center (or "C") channel mix.

The Allen & Heath GL2800 is a budget conscious, work-horse sound-reinforcement mixer designed to meet the needs in large clubs, houses-of-worship, theaters, halls, outdoor band shells, rehearsal studios, recording studios and anywhere a large format, quality sound-reinforcement mixer is needed.

Outstanding Performance
Allen & Heath circuitry provides exceptionally low residual noise from the mix head amplifier and output stages. Improved microphone preamplifiers maintain low noise and can except as much as +34dBu.
Stereo Line Inputs
Four dedicated stereo input channels provide dual L/R stereo line inputs, for a total of four stereo line level inputs.
Direct Microphone Outputs
Both stereo input channels also feature a mono microphone input with a standard 3-pin balanced XLR connection and a 1/4" phone microphone output. The microphone output is convenient for feeding ambient microphone signal to recorders, RTA measurement systems, etc.
12x4 Matrix Routing
The 12x4 Matrix is literally a mixer within a mixer. 4 output channels feature independent output level control and signal routing from any of the 8-sub groups, L/R stereo or Matrix External inputs (12x4). Applications include assisted listening mixes, additional monitor mixes, remote broadcasts, zone feeds, mono recording and stereo recording comps.
10 Auxiliary Sends
10 auxiliary sends provide adequate routing to external effects devices, monitors, etc.
8-Sub Group Outputs
8-sub groups are ideal for drum kit and background vocal comps. Individual channel feeds can be routed to multitrack recorders as well.
1/4" TRS phone inserts are located on all input channels, stereo mix output and sub-groups. The inserts enable direct, signal-loop routing to signal processors, monitor mixers, etc.
Direct Outputs
All input channels feature a direct output with a 1/4" phone connection. This allows for direct routing to large multitrack recorders, monitor mixers, etc.
System Link
An optional card provides the 37 pin D connectors necessary for integrating an additional GL2800. The Sys-Link allows the second mixer to operate as an input expander module.
Gooseneck Lamp Connections
Dual 4-pin male connections are provided for adapting gooseneck lamps.
