Dual-Function Function Live Sound 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 we are proud to present the new 4-buss dual-function GL2400 – the latest 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 7×4 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!
