Allen & Heath GX4816

The Allen & Heath GX4816 is a high-performance audio expander designed to enhance the input and output capabilities of SQ, Avantis, and dLive mixing systems, as well as the AHM-64 audio matrix processor. Housed in a 5U rack-mountable chassis, it offers 48 high-quality microphone preamps with individual phantom power indicators and 16 XLR line outputs, all operating at a pristine 96kHz sample rate.

For added flexibility, the GX4816 includes two DX ports, allowing connection to up to four DX expanders for further I/O expansion or integration with the ME personal mixing system. Its plug-and-play design ensures seamless setup via a single Cat5e cable, with automatic configuration and no need for manual IP addressing. This makes the GX4816 an ideal solution for professionals seeking to expand their audio infrastructure with reliable, high-quality connectivity.
