AAT – Multiroom PMR

Driver for integrating AAT PMR multiroom amplifiers, all models, with Control4 over Ethernet or RS-232 serial. The multiroom appears as an audio matrix: each PMR zone is bound to a room in the project, with input selection, volume, mute, bass, treble and balance.

It includes a logarithmic volume mode, which compensates for the PMR only becoming audible near half volume, and a maximum volume limit per zone.

Installation

1. Add the ZoomDH – AAT Multiroom PMR IP/RS232 driver to the project in Composer Pro.
2. Over the network, fill in IP Address and, if needed, TCP Port (5000 or the port configured on the panel). Over serial, bind the RS-232 connection to the controller serial port.
3. In the Connections tab, bind the sources to the inputs and each zone to its room.
4. Adjust Volume Control Mode and the maximum volume of each zone.

Features

• Audio zone control: on/off, volume and mute
• Switching of the 4 matrix inputs (analog and digital) to the zones
• Streaming inputs 7 and 8 and virtual optical connections
• Configurable maximum volume per zone
• Linear or logarithmic volume mode
• Bass, treble and balance adjustment from the user interfaces
• Real device state feedback, including changes made outside Control4
• Supports the PMR6, PMR7 and PMR8 models

Requirements

• Multiroom firmware 1.13 or later
• Multiroom with a static IP or DHCP reservation (TCP ports 5000 or 1024), or an RS-232 cable

Release notes

1. 2026101410/14/2026

   Driver rewritten on the current ZoomDH libraries, without the old AVSwitch library. Fix: when the multiroom sent several replies together, only the first was handled and volume, mute and input feedback was lost. A reply outside the expected format no longer discards the following ones. Minimum firmware check fixed (1.9 was accepted as newer than 1.13). New licensing library, with a 30-day trial. HTML documentation (PT/EN).

2. 2113/30/2026

   Turning zones on and off now uses mute instead of standby, at AAT's request.

3. 2108/29/2024

   Volume Control Mode property (linear or logarithmic).

4. 2098/6/2024

   Changed the standby/mute command.

5. 2085/5/2023

   Bass and treble in Navigator from OS 3.2.3.
