10. Tighten the two PIP mount-
ing screws until the PIP is
secured to the amplifier
back panel.
4.4 Install the Wiring
11. Connect the IQ–P.I.P.-MEM
to the IQ System via the
Crown Bus. See Section 4.6
for full instructions.
12. Connect the audio signal
wiring to the IQ–P.I.P.-MEM.
This includes the XLR input
wiring and, if desired, the
phone jack daisy chain wir-
ing. See Section 4.7 for full
instructions.
13. Reconnect amplifier to the
AC receptacle.
4.5 Adjust the Levels & Scale
Factors
14. Turn the level controls of the
amplifier to their full or maxi-
mum setting. This is required
by the IQ–P.I.P.-MEM. If
needed, use the software-
controlled input attenuators
on the IQ–P.I.P.-MEM to re-
duce the audio levels.
15. Configure the amplifier scale
factors. (Standard PIP-com-
patible amplifiers only—the
scale factors for PIP2-com-
patible amplifiers are set au-
tomatically.) It is necessary
to configure software scale
factors in the microproces-
sor of the IQ–P.I.P.-MEM in
order for it to properly inter-
pret the output signal level of
the amplifier model in which
it is installed. This is easily
done by connecting a host
computer to the IQ–P.I.P.-
MEM via an IQ interface and
the Crown Bus and running
the appropriate software
(see IQ for Windows online
help for more information).
The software will prompt you
for the amplifier model and
send the appropriate scale
factors to the PIP. The scale
factor values are listed in
Figure 4.8 along with the set-
tings of jumpers JP4 and
JP5.
Note: Since it is possible to
configure one channel of a
Com-Tech amplifier in the 8-
Ohm output mode and the
other channel in the 70-Volt
output mode, it may be nec-
essary to configure the scale
factors differently for each
channel.
nected first then the 18 pin
cable (B) is connected. Both
ribbon cables should extend
below the PIP2 input
adapter.
Next, insert the edge con-
nector of the IQ–P.I.P.-MEM
into the PIP2 input adapter
(see Figure 4.7) and insert
the assembly into the PIP
opening in the back of the
amplifier.
