System operating firmware The function of AHM-64 is determined by the firmware (operating software) that runs it. Firmware is updated regularly as new features are added and improvements made.

Layer-2 or Dante transport protocols. AHM-64’s scalability supports up to 268 system inputs and system outputs, and up to 96 IP remote controllers for volume control, music source selection, preset recall and more. It can also integrate with third party devices over GPIO, TCP/IP, or industry standard control systems.
2.3 Rear rack kit A kit is available for extra rack support of AHM-64, securing the unit to the rear of a rack cabinet in environments where vibration or mechanical stress are of concern. The rear rack kit is extendable and can fit racks between 485mm and 600mm deep.
Assignable Chromatic meter with variable colour and brightness. Factory default measures the highest level across all input and output channels, with peaks flashing red. 2. Fans Variable speed with temperature sensing. Make sure the ventilation opening is not obstructed. AHM-64 Getting Started Guide AP11781 Issue 3...
Refer to www.allen-heath.com for a list of available option cards. For Dante audio networking, use the M-SQ-DANT64 (SQ Dante V2) card, not the original M-SQ-DANTE card. AHM-64 Getting Started Guide AP11781 Issue 3...

6. Control Network RJ45 Gigabit Ethernet port. Connect a laptop, wireless router or switch to use with the AHM-64 System Manager, IP remote controllers, Custom Control app or TCP control. All devices on the network must have compatible IP addresses.
Slot for optional processing module. Refer to www.allen-heath.com for a list of available modules. Follow the fitting instructions of the optional module for installation. ⚠ Installation of any optional module must only be carried out by technically skilled personnel.

Fast Ethernet At connection or power up, AHM-64 will check the firmware version of the expander device and upgrade or downgrade the device to match the main unit firmware. Up to 2x dSnake 48kHz expanders can be daisy-chained over SLink, provided the first expander is an AR2412 or AB168, and the second expander is an AB168 or AR84.

A DX Hub can be connected to the SLink port for further expansion with up to 8 DX expanders. It also enables a single cable link to the AHM-64 processor in cases where multiple expanders are located on a different floor, area or building.
6.3 Other SLink connections The SLink port can be connected directly to another AHM-64 unit, an SLink enabled Allen & Heath mixer such as SQ or Avantis, or a dLive system fitted with a gigaACE card. This connection enables 128x128 channels of audio.
7. Connections - Control A computer, wireless router or switch can be connected to the Network port to use with the AHM-64 System Manager, IP remote controllers, Custom Control app or TCP control. For all connections, use CAT5e (or higher specification) cables up to 100m long.
7.4 TCP Protocol A TCP Protocol for control and interrogation of AHM-64 parameters is available and documented at www.allen-heath.com. Clients should be configured to use TCP port 51325 (unsecured) or the TLS/TCP port 51327. Check www.allen-heath.com for drivers or project templates for leading control systems such as Crestron or AMX.
