The DX88-P is a fixed installation I/O Expander for Allen & Heath 96kHz digital mixing systems. It provides 8 remote-controlled mic/line preamps and 8 line outputs. It connects to the mixer over a single Cat5 cable.

A second DX88-P, DX164-W, DX012 or DX168 can be connected via the DX B connection.

The DX88-P can be operated freestanding or rack-mounted using the optional DX88-P-RK19/X kit.
