Allen & Heath GL2400 Series
16, 24, 32 and 40 Channel Options

Available in 16, 24, 32 and 40 channel frame sizes - all individual vertical PCB's and copper bus bar grounding - the GL2400 benefits from the latest audio circuitry with an extended preamp gain range of 74dB with input on XLR or jack, differential balanced +26dBu outputs, and a new ultra-quiet mix head amp design for optimum dynamic range.

Dual Functionality
As pioneers of dual functionality, Allen & Heath ensured that every detail of the concept has been carefully implemented in the GL2400. When mixing at Front of House, the mixer provides combinations of pre- and post-fade aux sends on a per-channel basis for stage mixes (post-fade control is essential for radio mics in a theater!) They give you the choice. For example, a pre-insert, pre-EQ option is available per channel for the direct outputs and aux sends.

As a monitor engineer, you'll be delighted to find all your available aux sends can be post fade and are controlled by fader masters with output mutes (so you can AFL mics before switching on), inserts and balanced XLR drive. And they give you an engineer's monitor wedge fader and XLR output.

Performance
They have redesigned their audio performance -the figures speak for themselves, but above all, it will satisfy the most demanding situations, whether it's a hot AV feed or XLR input where the maximum input capability is 34dBu! From their new low-noise mix amp through to the differential balanced 26dBu outputs, everything's been thoughtfully designed to ensure the best sonic performance possible, which is why they always insist on individual vertical PCB's and copper bus bar grounding.

Third Fader
There are three master faders on the GL2400. Their flexible M output allows you to create a center-fill or sub-bass mix from Aux 6 which means you can dial in exactly what you need from each channel. Naturally, it can be a mono sum of the LR mix, but it can also be configured as your monitor wedge output, and it has a balanced XLR and mute.

7x4 Matrix
The 7x4 matrix is a big feature for corporate AV work, specialized recording feeds and personal monitoring. They have provided a smart external input facility: plug into the external input on Matrix 1 and it's normalized to the other matrix mixes. Combine this with the mic out facility on the stereo input channels to provide an ambient mix for IEM. Each matrix output derives its mixes from the L&R busses, groups 1-4 (even in monitor mode) and the external input which has a pot control. Of course, each output has an illuminated mute switch.

Dual Stereo Channels
These two multi-function channels provide a mic and 2 stereo line inputs each. Use the channels as mic inputs while the 4 stereos are independently routed to LR, or combine stereo sources such as backing tracks and reverbs while the mics are patched elsewhere, or use conventional stereo channels while the second inputs provide additional returns and the mics patch into the matrix for ambience.
