Details

The Allen & Heath GL2800-40 40 Channel Live Sound Mixer is a compact, dual function, LR, M, 8 group, 10 aux, 12x4 matrix console. It is a brand new dual-function mixer derived from our classic GL Series, the most popular mixers in the world for mid-range mixing applications. One glance at this new design will confirm that all our design experience and knowledge has been distilled into one amazingly capable console. Uniquely at this level, GL2800 is equipped with 10 auxiliary sends - including a dedicated stereo aux - and using the 12x4 matrix, provides the ideal solution for IEM and stereo recording. 8 audio groups and L,R and M busses are also provided, allowing for full dual functionality with 10 mixes with faders, inserts and XLR drive. And at the heart of this design is the new gain structure allowing a whopping 34dBu maximum input capability and a new ultra-quiet mix head amp section, delivering excellent audio performance. GL2800 is designed for use in any live sound application, including theatres, music venues, houses of worship, festivals, corporate AV, stadiums, etc. With its neat, intuitive layout and straightforward analogue technology, clean audio and high dynamic range, its performance easily rivals that of the best digital consoles.
