Product Description
Based on ALEEN-HEATH's successful GL2200, the 4-bus dual-function GL2400 is the latest generation of a classic mixer with 40 channels. Based on cutting edge technology, this piece was carefully tought-out in every minutiae so as to provide the best experience possible for the end-user. For instance, the mono output can be configured as LR sum, wedge, aux-fed sub or centre master. It also acts as a monitor with a huge amount of mixing application, like stereo recording, zone feeds, delay fill speakers and more.
