The DX88-P provides 8 inputs and 8 outputs on Phoenix/Euroblock connectors for fixed installations — an easy way to add local or remote analogue expansion to AHM Audio Matrix Processors and other Allen & Heath systems.
I/O
8 Ins + 8 Outs
Eight mic/line inputs with recallable 5–60dB gain, Phantom Power and −20dB pad, plus eight line outputs — all on Phoenix/Euroblock connectors.
Installation
Rackmountable
Optional rack mount kit fits two DX88-P units in a single 1U 19" slot. Can also be mounted alongside a DX Hub or GPIO module.
Connectivity
Cascade Mode
Cascade mode allows daisy-chaining of up to 2 DX expanders on each DX port for additional remote I/O. Up to 8 units on a single DX Hub.
Setup
Plug-and-Play
No configuration or IP addressing required — just connect to your mixer. Firmware updates handled automatically by the host.
Flexibility
Put It Where You Need It
The DX88-P can be placed up to 100m away from the mixer, connecting via a single Cat5e cable through the DX A port to the mixer or upstream DX Expander.
A second RJ45 port (DX B) is provided for daisy-chaining to a downstream DX Expander for additional remote I/O, making it ideal for distributed fixed install environments.
Rack Mount
Install Options
An optional rack mount kit installs up to two DX88-P units in a 1U 19" slot — ideal for interfacing with analogue AV switchers and equipment in equipment rooms. Can be combined with the DX Hub or GPIO rack kit for a fully integrated rack solution.
Scalability
Expand As You Grow
Multiple DX88-P units can be added to a system — up to 8 units on a single DX Hub. Combined with DX Hub's 4 ports this gives enormous I/O flexibility for larger fixed install projects without running additional cable back to the rack.
