ALLEN & HEATH DX88-P - Digital Mixing Systems Manual

Introduction

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.

information Update the mixing system to the latest available version of firmware before connecting the DX Expander. The unit might operate incorrectly when running earlier firmware.

Check that you have received the following with your DX88-P unit:

16 x 3-Way Phoenix Contact Plug
DC 12V power supply

Front panel

Power LED indication and Ready Indicator.
Ready lights up when the unit is successfully booted and ready to pass audio.

Rear panel

Inputs
Balanced Phoenix mic/line inputs.
Output
Balanced Phoenix line outputs.
DC Input
DC 12V connector via external PSU.

information Use only the power supply provided with the product (Adapter Tech EDA4012-C14, A&H part code AM13303). The use of a different power supply can cause electrical or fire hazards.

DX A
Ethernet port for connection to the mixing system. The cable carries the audio signals as well as preamp control and system status data.
