Allen & Heath GL2400 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 GL2400 is available in a 16, 24, 32 and 40 input chassis with a compact enclosure ideal for any custom, portable flight case.

The GL2400-24 is the 24 input version, complete with 24 line inputs, 24 microphone preamplifier's and 4-buss group routing. There is absolutely no shortage of routing possibilities with 2 stereo input channels, 6 Auxiliary sends and a 7x4 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 GL2400 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
2 stereo input channels provide dual L/R stereo line inputs, for a total of 4 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.
7x4 Matrix Routing
The 7x4 Matrix is literally a mixer within a mixer. 4 output channels feature independent output level control and signal routing from any of the 4-sub groups, L/R stereo or Matrix External inputs (7x4). Applications include assisted listening mixes, additional monitor mixes, remote broadcasts, zone feeds, mono recording and stereo recording comps.
6 Auxiliary Sends
6 auxiliary sends provide adequate routing to external effects devices, monitors, etc.
4-Sub Group Outputs
4-sub groups are ideal for drum kit and back ground vocal comps. Individual channel feeds can be routed to multitrack recorders as well.
Inserts
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 GL2400. 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.

    Allen & Heath GL2400 reviews

    GL2400-24 24-Input, 4-Buss Live Sound Console is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from GL 2400 Gets It Done I'm a TD at a college and chose the GL2400 to replace my 15 yr old Crest 24x4x2 that I use to mix small bands, acappella groups, and coffeehouse performers. I have an old GL2200 in another venue, but like many, I was initially concerned about the potential differences in quality and sound in a new 2400. No worries. The 2400 is at least as good, solidly built, and although it takes up only 3/4 of the footprint of the Crest, it's loaded with features. The mic preamps sound clean and warm, and the EQ does everything I ask of it without overkill. I haven't used the matrixing yet, but I can see it being very useful for recording and media patches. The console is marketed with optional gooseneck LED lamps that use a pair of 4 pin XLR connectors on the back of the deck. Not sold on the that very stark LED color yet, but the lamps angle out perfectly for the left/right input configuration. Great console!

    Rated 5 out of 5 by from Nice board for the money Right out of the box it is easy to use and set up. All controls are well laid out and their function is clear. Board is very quiet. I love the 6 busses, and the matrix for mixing monitors from the FOH console. All normaly used outputs are XLR, not TRS, so you dont need adapters or special cables for monitors or other sends. The only issue I have, and it is small, is that the mute and solo buttons are inverted from older consoles, so you have to relearn which to push when you want to solo a channel.
