Introducing the Allen & Heath GL28 GL2800M 00M The monitor application has grown dramatically in recent times with the evolution of multiple wedge and stereo in-ear systems which can quickly exceed the mix capability of all but the most expensive consoles. The GL2800 GL2800M 00M adds a fully featured yet affordable dedicated monitor console to the popular GL Series live sound range.

The Input Channel INSERT CHANNEL INPUT Balanced XLR input pin 2 hot. Accepts mic or line level signals. For unbalanced sources use a cable or adapter that connects XLR pin 3 to pin 1. INPUT CHANNEL PREAMP 54dB gain range with 20dB pad to accept signals from -60dBu to +14dBu nominal. Press PAD for hot signals up to +34dBu max. Press HPF to switch in a 12dB/octave 100Hz lo cut filter.
The 16 Channel Mix Sends The GL2800 GL2800M 00M features 16 mixes (aux sends). These are used for combinations of stage wedge and in-ear monitor sends. The controls are colour coded in pairs to quickly identify each mix. The mixes may be configured as mono or stereo, and pre or post the channel trim fader according to your requirement.

Use this to adjust the overall sound of the mix, for example to satisfy the preference of a performer using in-ears, or to notch out wedge speaker feedback when an outboard EQ is not available.
The Engineer’s Monitor System The GL2800 GL2800M 00M provides three independent engineer’s monitor outputs. By setting configuration switches the engineer can listen to each mix the way the performer hears it.

The Engineer’s Toolbox The GL2800 GL2800M 00M provides a comprehensive combination of facilities to help the monitor engineer set up and keep control of the multiple wedge/in-ear stage environment. Includes the engineer’s monitors, headphones sockets, talkback section, built-in oscillator/noise test generator, mute group masters and the global settings configuration switches.

GL2800M Operating Tips The following is a collection of brief application notes, hints and tips to help the operator to get the most out of the uniquely capable GL28 GL2800M 00M live sound monitor mixing console. They are written as a concise reference to spark your imagination to creatively and effectively deal with the many challenges faced in modern day mixing.
Using the Oscillator / Noise Generator The GL28 GL2800M 00M includes a useful signal generator able to produce a pure 1kHz sine wave tone, or a pink noise test source. This is invaluable in testing the system components and setting up correct gain structure. The generator can be routed independently to the various console outputs. OSC/NOISE MIN MAX PINK NOISE 1kHz OSC A ON Use the 1kHz tone to line up the connected equipment.
Polarity POLARITY Refers to the positive (+) and negative (-) wires of a loudspeaker or balanced audio connection. The console input channels and mix masters include POLARITY switches which reverse the + and – input connections.
Stage wedge speakers The type and position of the floor wedge speakers used for stage monitoring are critical to both meeting the performers needs and keeping stage noise under control. Use a speaker designed for the monitor application and with adequate power handling for the type of show. Know the directional response of the microphones being used as this can determine the optimum position of the speakers to minimise feedback.
TALKBACK MIC Monitoring many mixes The GL2800M GL2800M provides a dual AFL monitoring system so you can check the stage wedge mixes in your own floor wedge, and check the in-ear mixes using your own IEM system or the console headphones. Before starting, decide which mixes are to feed each type of monitor and then configure the GLOBAL SETTINGS switches accordingly.
