* A suitable solid-state relay for use in
such a circuit is available from Crown
(CPN D8063-6). Contact your local
Crown representative or the Crown
Factory Parts Department (219-294-
8200) to order.
10.5.1 AUX Output
The AUX Output feature provides
either 0 or +15 VDC across pins 3
(ground) and 4 (+) when the feature
is turned on by IQ for Windows soft-
ware, depending on whether the
polarity is set to inverting or non-
inverting (see Section 9.4). A total of
10 milliamps of current is available.
A 1.8 K ohm resistor protects against
shorts (See Figure 10.12).
There are many possible uses for
the AUX Output. For example, it can
be used to turn on auxiliary cooling
fans. To do this the AUX connector
might be used to close a relay.* The
relay would then turn the fans on or
off. This is shown in Figure 10.13.
By monitoring the operating condi-
tion of amplifiers with IQ for Win-
dows, the need for additional cool-
ing would be apparent. The IQ for
Windows software could then be
used to turn on the appropriate AUX
connector. (For more information
about turning the AUX feature on/
off, consult the IQ for Windows soft-
ware documentation).
