AYRE VX-R - Manual (Page 5)

Do not connect the loudspeaker outputs to any
speaker switch-box, accessory, or test equipment
that has a common ground connection.
AyreLink Ports
The AyreLink communication system provides a convenient
way to control your audio system. There are two AyreLink ports
on the rear panel of the VX-R amplifier. Each port has four
contacts and contains both an input and an output. Both ports
function identically and may be used interchangeably.
AyreLink connections are made with commonly available
two-line telephone line cords using modular (RJ-11)
connectors. (These are the cords that connect the telephone set
to the wall in many countries.) They are readily available in
different lengths and various colors at most electronics stores.
Be sure to use two-line telephone cords to make
AyreLink connections. These can be identified by
the four gold contacts on each connector.
Single-line cords with only two gold contacts will
not function in this application.
The linked components may be joined in
any convenient order.
The linked components should be connected in daisy-chain
fashion, connecting each component to another until all of the
linked components have been connected.
When connecting the linked components to form
a chain, be careful not to connect the two ends of
the chain. Closing the chain to form a loop will
cause the AyreLink system not to function.
