AYRE MX-R - Manual (Page 6)

If there are no other AyreLink components in your system, the
MX-R amplifiers may also be controlled by a trigger output
from another component. In this case, connect the AyreLink
ports of your amplifiers in daisy-chain fashion as described
above. The unused AyreLink port on an amplifier at either end
of the AyreLink chain can then be used as a trigger input.
Additional details can be found in the chapter “Customization
and Configuration”.
