ALLEN HEATH DX88-P 96kHz Digital Mixing Systems

Product Information

The DX88-P is a fixed installation I/O Expander designed for Allen & Heath 96kHz digital mixing systems. It features 8 remote controlled mic/line preamps and 8 line outputs. The unit connects to the mixer using a single Cat5 cable. Additional expanders such as DX88-P, DX164-W, DX012, or DX168 can be connected via the DX B connection. The DX88-P can be used freestanding or rack mounted with the optional DX88-P-RK19/X kit. It is important to update the firmware of the mixing system before connecting the DX Expander to ensure proper operation.

Product Usage Instructions

1. Ensure that the mixing system is updated to the latest available version of firmware.
2. Connect the DX88-P to the mixing system using a Cat5 cable. Use the DX A port for the initial connection.
3. If connecting a second unit, use the DX B port for daisy chaining.
4. Make sure there is proper ventilation at the sides and back of the unit. Avoid obstructing the vents during operation and prevent dirt or liquid ingress.
5. Use only the provided power supply (Adapter Tech EDA4012-C14, A&H part code AM13303) to avoid electrical or fire hazards.
6. For indoor use only.
7. Use Cat5e or higher STP cable for connections with a maximum cable length of 100m per connection.

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.
  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.
