IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
C. Reset Switch
A multifunction reset switch is pro-
vided to restore the IQ–P.I.P.-MEM
to a prior state. It can be de-
pressed with a straightened paper
clip through the small hole in the
PIP panel. Press the reset switch
for less than 2 seconds and all set-
tings, except the amplifier model
scale factors, will be reset with
“user default” parameters and the
DSPI will flash once. (If no “user
default” settings have been stored,
the unit will be reset to the “factory
default” settings described next.)
Press the reset switch for more
than 2 seconds and the same set-
tings will be reset with “factory de-
fault” parameters and the DSPI will
flash twice. After the unit has been
reset to the factory default settings,
it will behave like a standard P.I.P.-
FX until it is reprogrammed by an
IQ System or it is toggled to the
“user default” settings.
D. AUX Connector
A 3-pin male mini XLR connector is
provided to control auxiliary equip-
ment. When the AUX feature is
turned on, +15 VDC is provided
across pin 1 (gnd) and pin 3 (+). A
nominal current of 10 mA is avail-
able. The AUX connector also in-
cludes a high-impedance input that
can sense logic signals.
E. DSPI
The DSPI is a Data Signal Presence
Indicator which flashes whenever a
valid IQ command has been re-
ceived. The indicator can also be
forced to stay on to aid rapid
troubleshooting of the Crown Bus
wiring.
F. Crown Bus Input Connector
A lockable 5-pin female DIN con-
nector is provided for input connec-
tion to the Crown Bus. A mating
Switchcraft 502 series connector
can be ordered from Crown (part C
7776-5). Pin 1 is negative (–), pin 2
is positive (+), and pin 3 is ground
(gnd). Pins 4 and 5 are not used.
G. Crown Bus Output
Connector
A lockable 4-pin female DIN con-
nector is used for output connec-
tion to the Crown Bus. A mating
Switchcraft 502 series connector
can be ordered from Crown (part
C 7777-3). Pin 1 is negative (–) and
pin 2 is positive (+). Pins 3 and 4
are not used.
H. Input Switches (S1, S2)
An 8-section DIP switch is used to
configure each input. These
switches are located on the bottom
circuit board. S1 configures the in-
put of Channel 1 and S2 configures
the input of Channel 2. The
switches activate a microphone
preamp and enable phantom
power. The preamp can be turned
off (0 dB gain) or set to either 20 or
40 dB of gain. See Section 4.1.
I. PIP Edge Connector
The gold-plated edge connector of
the top IQ circuit board inserts into
the PIP connector inside the back
of the amplifier. Use care when in-
stalling a PIP module to be certain
that the edge connector is properly
inserted into the amplifier’s PIP con-
nector.
