then in turn control amplifiers linked by the
AyreLink communications system. Connect the
AyreLink ports of your components in a daisy-chain
fashion as described in the chapter “Connections and
Installation” with the AX-5 at one end of the chain.
The unused AyreLink port on the amplifier is then
used as a trigger input.
Rear view of AX-5 amplifier. An adapter cable must be fabricated to connect the
trigger output of the control component to the
AyreLink port of the AX-5 amplifier. The easiest
way to do this is to remove the modular (RJ-11)
connector from one end of a two-line telephone line
cord. (This is the type of cord that connects the
telephone set to the wall. A two-line cord will have
four gold contacts on each connector.) Then attach
the connector appropriate for the component with
the trigger output. Please refer to the owner’s
manual of that source component for details.
The trigger voltage should be between
+5 and +12 volts DC for proper
operation. The current draw of the
trigger input on the AyreLink port is
less than 5 mA.
There are two signaling methods that may be used;
level and pulse. The AX-5 automatically senses
which type of trigger signal is being sent and
responds accordingly.
A positive-going pulse of greater than 250 msec is
treated as a level-sensitive trigger. Shorter pulses
are treated as a pulse-sensitive trigger. The
minimum detectable pulse length is 200
µ
sec.
