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, they are proud to present the new 4-bus 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 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 center 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. Plenty of hard work has gone into the design of the audio circuitry in this mixer, and with its amazing headroom and new ultra-quiet mix head amp, this is the best performance yet!
