Allen & Heath GL2800 Series
24, 32, 40, 48 and 56 channels

The Allen & Heath GL2800 is an 8-bus dual function analogue mixing
console designed for professional audio applications. Whether mixing FOH,
monitors or both, recording live or in the studio, installed in a busy
venue, out on the road touring, or earning its keep in rental stock, the
GL2800 provides the perfect solution.
Dual Functionality
Allen & Heath have taken their pioneering dual functionality a leap
further with new capability for multi-output and personal monitor mixing.
10 Auxes include a dedicated stereo aux for creating stereo recording
or monitor feeds, or new applications such as sending to a mix of two
reverbs. As a monitor console, you get up to 14 mixes such as 8 wedges
and 3 stereo IEM, complete with dedicated engineer's monitor using the
M fader. With up to 56 input channels you can handle any festival or gig
at FOH or on stage with no controls redundant in any mode.
Performance
Their new 74dB range, extended headroom mic preamp can handle the widest
range of signals you are ever likely to encounter. Switch between XLR
mic and TRS line sources, or plug into the XLR only to handle mic or line
level stage sources up to a massive +34dBu. From the new low-noise mix
amp through responsive 4 band EQ to the differential balanced +26dBu outputs,
with its individual card and solid copper bar grounding, every stage has
been carefully designed to ensure optimum gain structure and the best
sonic performance possible
12x4 Matrix
A matrix with such capability is a major addition to any console at
this price point. Fed from the 8 groups and L, R and M mixes, each matrix
includes an external trimmable input with smart auto-switching to accept
common mono, stereo or independent sources. Use just two standard jack
cables to patch across from the stereo channel mic preamps to add stereo
ambience to two stereo recording or monitor mixes. Nothing is wasted as
the stereo channels may still be used as returns or line inputs. In monitor
mode, the matrix provides a quick way to create studio quality IEM mixes
with ambience and 'more me' control. You even get matrix talkback and
mono or stereo monitoring, perfect for keeping in touch with the performers.
Stereo Capability
Responding to the demands of modern mixing, the GL2800 is equipped with
plenty of stereo functionality. Aux 9-10 has dedicated level and pan control
complete with mute and stereo monitoring. Listen to the matrix in mono
or stereo, create an LCR mix from the LR and M buses, and add no fewer
than 6 stereo line sources using the full feature stereo channels and
2 extra short fader dual stereo returns in the master section.
A well equipped Toolbox
Engineers will be pleased to discover the many thoughtful touches that
make the GL2800 a joy to use. Take for example, the recessed channel pre/post-EQ
switches, the 3 headphones outputs including a small jack earpiece socket,
the talk latch mode for using a switched handheld talkback mic, the built-in
oscillator / pink noise generator with patchable output, extensive metering
and much more.
