6.1 Audio expanders over SLink
When an audio expander is connected, the SLink port detects the type of device and automatically
switches to the relevant Allen & Heath protocol, sample rate and Ethernet speed. The table below lists
compatible audio expanders. Visit allen-heath.com/everything-io/ for more information on our range of
expansion options.

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. Connection of 2x AR2412 is not
supported.
Up to 2x DX168, DX164-W, DX012 expanders in any combination can be daisy-chained over SLink. AHM-
64 does not support redundant connection to DX expanders.
