Allen & Heath GL2800M Overview

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 GL2800M-848 is a 48 input, 8-buss monitor console designed to address the needs of accurate stage and in-ear monitor mixing at a fraction of the cost. The mixer is capable of up to 16 simultaneous mixes globally assigned as mono or stereo with level and pan. Sound engineers benefit from actual wedge of IEM monitoring, for an accurate representation of what the talent hears.

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 GL2400M-848 is a budget conscious, work-horse monitor mixer designed to meet the needs in large clubs, houses-of-worship, theaters, halls, outdoor band shells, rehearsal studios, recording studios, etc.

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.
Up to 16 Monitor Mixes
16 mixes globally assigned as mono or stereo with level and pan settings.
Engineer Wedge or IEM Monitoring
Engineers won't have to subject themselves to headphone monitoring. Mix AFL is assignable to either wedge or IEM monitor, for an accurate representation of what the talent hears.
Four Mute Groups
Four assignable mute groups are provided for accurate channel control.
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.
Gooseneck Lamp Connections
Dual 4-pin male connections are provided for adapting gooseneck lamps.
