AHM Release Notes Firmware and System Manager V1.42

General Information

This document details the release notes for Allen & Heath AHM firmware and System Manager software. It outlines new features, improvements, fixes, and known issues for various versions.

Compatibility Note: Only matching versions of System Manager and AHM firmware can be run together (e.g., System Manager V1.02 will not connect to a unit running V1.00 without prior update).

The System Manager application includes firmware files for the AHM matrix processors. For the latest version, refer to www.allen-heath.com.

Important Update Information: Updating AHM firmware resets Presets and current settings. Always save your settings as a Config before performing an update, and restore your Config or a Template Config afterward. Ensure Custom Control devices are updated at the same time as or prior to updating the AHM processor. Updating AHM firmware also resets Email Notification settings.

Security Note: Due to security improvements, AHM V1.30 firmware and higher will only connect to Custom Control app V1.3.0 or higher. Earlier versions of Custom Control will not connect, displaying an incorrect username/password error. Please ensure your Custom Control devices are updated at the same time as or prior to updating the AHM processor.
