Allen and Heath GL2400-40 40-Channel Mixer

Manufacturer's Description for Allen and Heath GL2400-40 40-Channel Mixer

For 35 years, Allen & Heath has designed truly innovative mixers for the real world and has earned its enviable reputation for superior performance, functionality and build quality.

Building on the success of the industry-standard GL2200, Allen and Heath are proud to present the new 4-buss dual-function GL2400 - the next generation of a mixing classic.

This mixer is designed for professional applications. Whether mixing FOH, monitors, or both, recording live or in the studio, installed in a busy or house of worship, out on the road touring or earning its keep in rental stock, the GL2400 provides the perfect solution.

Engineered for modern engineering techniques, every detail in this mixer has been carefully thought out to provide the very best mixing experience. For example, the mono output can be configured as LR sum, wedge, or aux-fed sub or centre master. In Monitor mode, all six auxes are available on faders with mutes, inserts, meters and XLR drive. The new 7x4 matrix with ambient mic capability opens up a huge number of mixing applications, including stereo recording, zone feeds, delay fill speakers and stereo in-ear monitor mixes.

We have worked hard at the design of the audio circuitry in this mixer, and with its amazing headroom and new ultra-quiet mix head amp, we believe that this is our best performance yet!

Dual Functionality
As pioneers of dual functionality, we have ensured that every detail of the concept has been carefully implemented with no controls redundant in either mode. When mixing Front-of-House, the monitors can be set pre-insert as well as pre-EQ to prevent your house mix EQ and compression affecting the stage mix. Per channel aux switching means you can mix pre-fade with post-fade sends such as theatre radio mics and sound effects. As a monitor console, the aux masters get faders, inserts, mutes, meters and balanced XLR drive. You even get a fader controlled engineer' wedge feed. The Groups and LR mixes are still available to create yet more sends. In monitor mode the GL2400 can provide up to 10 mixes, for example 6 wedge and 2 stereo IEM.

Performance
Our new mic preamp has an extended 74dB gain range with massive headroom able to deal with the widest range of signals right up to +34dBu. From our new low-noise mix amp through responsive 4 band EQ to the differential balanced +26dBu outputs, every stage has been carefully designed to ensure optimum gain structure and the best sonic performance possible.

Third Fader
There are three master faders on the GL2400. Our configurable M fader lets you create an LR sum mono fill, an engineers monitor wedge feed, or a dedicated centre or sub-bass speaker mix from Aux 6 which means you can dial in exactly what you need from each channel. L, R and M each provide a dedicated meter, mute, AFL and balanced XLR output.

7x4 Matrix
The matrix is a big feature for corporate AV work, specialised recording and broadcast feeds, and personal monitoring. Smart auto-switching of the external inputs lets you add a common mono, stereo or independent sources to the matrix. Cross patch from the stereo channel mic breakpoints to add room ambience to your recording and IEM feeds.

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. True versatility in a tiny space... zZounds is an authorized dealer of Allen and Heath products.
