USP2.
4.1.4 Crown Bus Daisy Output
Connector
An RJ-45 connector is provided for
normal daisy wiring output to the
next device on the loop in the Crown
Bus.
4.1.5 Balanced Audio Inputs
A female XLR connector is provided
for balanced audio input to each
channel of the amplifier. Do not use
the Ch.2 input if the amplifier is
configured in either Bridge or Par-
allel-Mono mode.

4.1.6 Balanced Daisy Outputs

A male XLR connector is provided
for balanced audio daisy chaining
for each channel. Each daisy output
connector can be set to pass pro-
cessed or unprocessed signal from
its respective channel via jumper
settings.
4.1.7 AUX Input/Output and
Listen Bus Connector
An RJ-11 connector provides three
functions. The AUX output delivers
15 VDC at 10 mA maximum output
when switched on and may be con-
trolled via software or may be pro-
grammed to switch when a fail con-
dition is present on any channel.*
The high-impedance (10 K ohm) AUX
input can sense logic signals and
can be programmed to activate sys-
tem mute or report fault conditions
when a logic high is present. (See
Section 5.3.2 for more information.)
* The AUX output uses inverse logic
when it is configured to report a fail
condition. Normally high, it switches
low when any channel fails a test. In this
way it can also indicate a power loss.

IQ-PIP-USP2
Either amplifier channel's output can
be monitored as a balanced line
level signal which is sent to pins 1
and 6 of the RJ-11 connector (soft-
ware selectable).
4.1.8 Crown Bus "Drop Out"
Relays
"Drop out" relays are provided on
the Crown Bus ports to maintain the
continuity of the IQ communication
loop even if the IQ-PIP-USP2
loses power.

4.2 Hardware Controls

The following IQ-PIP-USP2 controls
are accessed via hardware switches
located on the unit:

4.2.1 Daisy Select Jumpers

Jumpers select through or pro-
cessed signal daisy routing to the
Channel 1 and Channel 2 daisy XLR
connectors. The Channel 1 daisy
connector can be set for through
(IN) or processed (OUT) signal from
Channel 1, and the Channel 2 daisy
connector can be set for through
(IN) or processed (OUT) signal from
Channel 2. See Figure 4.1.

IQ-PIP-USP2 Reference Manual
IQ-PIP-USP2
An 8-section DIP switch is used to
set the IQ address of the unit. A valid
IQ address is any number from 1 to
250. Numbers higher than 250 are
reserved for special use. An ad-
dress of "0" places the unit in stand-
alone mode. In this mode, the IQ
bus port is disabled and the PIP will
not function with IQ software.
This switch is located on the under-
side of the circuit board. Each IQ
component on a Crown Bus is given
a unique IQ address so it can be
independently controlled and moni-
tored. Two or more IQ components
of the same type should NEVER have
the same address on the same
Crown Bus loop.
For information on setting the IQ
Address Switch, see Section 3.1.

4.2.3 Scaling Switch (S3)

A 4-section DIP switch is used to set
the input and output scaling. This
switch is located on the under-side
of the circuit board. The factory-
default setting is +20dBu.
For information on setting input
and output scaling, see Section 3.1.

4.2.4 Reset/Preset Switch

A recessed reset/preset switch, ac-
cessible from outside the PIP panel,
performs two functions. First, it en-
ables the IQ-PIP-USP2 to be re-
stored to factory default settings,
and second, allows the user to re-
call any of ten presets. A straight-
ened paper clip or similar small ob-
ject is required to press the reset
switch.
To select one of the ten presets,
complete the following steps:
Remove all input signals. With the
IQ-PIP-USP2 Reference Manual
power on, briefly press the switch for
less than two seconds to toggle
through the 10 user-defined presets
stored in firmware. Each press will
increment the selected preset by
one. After the switch is released, the
DATA light will flash rapidly for a
moment, then the PRESET indicator
will blink to indicate the preset num-
ber selected. Restore input signals.
To restore the unit to the factory
default settings, complete the fol-
lowing steps:
Remove all input signals. With the
power on, press the switch and hold
for more than 2 seconds, or until the
DATA indicator blinks twice, and all
settings will be reset to factory de-
fault. When the switch is released,
the DATA indicator will flash rapidly
for a moment. Restore input signals.
To clear all memory and set to
factory default presets:
Important: This action will re-write
the flash memory and erase stored
presets. The settings will be reset
to factory default, with the firmware
re-writing to flash memory.
Remove all input signals. Apply
power. Press and hold the switch.
The Data and Preset lights will si-
multaneously flash. After 7 flashes,
release the switch when the lights
are on. Lights will flash back and
forth, then data light will flash by
itself. If this does not occur, repeat
the process.
After the unit has been reset to the
factory default settings, it will behave
like a standard until it is repro-
PIP
grammed by an IQ System. Restore
input signals.
