IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
3 Features
With an IQ–P.I.P.-MEM module a
Crown amplifier can be monitored
and controlled by an IQ System.
This typically involves a host com-
puter (usually a PC), attached to
the IQ System via an IQ2-compat-
ible IQ interface, running IQ soft-
ware. Please contact your Crown
representative or Crown’s Technical
Support Group if you are unfamiliar
with IQ software.
3.1 Amplifier Information
(PIP2 amplifiers only.) Several items
of information about an amplifier
can be displayed by the IQ soft-
ware. These include the manufac-
turer, model, date code, serial
number and revision level. Which
items are available depends on
both the amplifier and the IQ soft-
ware used.
3.2 Amp Mode
The stereo/mono mode of the
amplifier can be stored into the
unit’s memory so the IQ System is
aware of the amplifier’s stereo/
mono switch setting. Storing this
setting serves as an “electronic
reminder” to the system—however,
the stereo/mono mode cannot be
controlled with this setting. The
modes are Stereo (Dual), Bridge-
Mono and Parallel-Mono. This
software amp mode setting is
controlled by the IQ System.
3.3 Power Control
Each channel’s high-voltage supply
can be independently turned on
and off with the Power control. The
IQ System is used to set this
control.
3.4 Input Signal Level
Monitor
The input signal level of each
channel can be monitored by IQ
software. This monitor feature has
a range from +16 dBu to –40 dBu
in ½ dB steps.
3.5 Signal Mute
The output signal of each channel
can be independently muted by the
IQ System. The function typically
provides 80 dB or more of
attenuation.
3.6 Polarity Inverter
The polarity of the input signal of
eachchannel can be independently
inverted by the IQ System.
3.7 Input Signal Attenuator
An attenuator is available at the
input of each channel to control the
input signal level. These atten-
uators are controll and monitored
by the IQ System. Each input
attenuator has a range from 0 dB to
–80 dB in ½ dB steps. (Zero equals
no attenuation.)
3.8 Output Signal Level
Monitor
The output signal level of each
channel of the amplifier can be
monitored by the IQ System. This
monitor feature has a range from –
40 dB to 0 dB where 0 dB is
referenced to the rated output
voltage of the amplifier model. (This
is assumed to be 70-V or the rated
8 ohm output for Com-Tech
amplifiers or the rated 8 ohm output
voltage for all other amplifiers.)
