Crown IQPIPUSP-2 Brochure
IQ-PIP-USP2
ULTRA SERIES
esigned for use with PIP2-compatible
amplifi ers*, the IQ-PIP-USP2 connects
the amplifi er to the Crown Bus of an IQ
D
System, allowing the amplifi er to be controlled
and monitored via IQ.
The IQ-PIP-USP2 offers an extensive list of
features, including output signal delay for precise signal matching, auto standby for reduced
energy costs, plus eight independent, fully
adjustable fi lters per channel.
The IQ-PIP-USP2 also provides on-screen
error reporting of fault, short (high temperature), and excessive distortion, so you
can know quickly if any changes occur in
your amplifi er’s status. Meanwhile, the IQPIP-USP2’s real-time load supervision feature
ensures you will be notifi ed immediately of any
catastrophic changes to the load.
Offering crisp, clear sound and the widest
dynamic range possible with full 24-bit signal
processing, the IQ-PIP-USP2 provides amazing power and fl exibility in one compact—and
very affordable—module.

800-342-6939 or 219-294-8200. Also, visit the
Crown Audio website at www.crownaudio.com.
* Many older PIP-compatible amplifi ers can be modifi ed
for use with the IQ-PIP-USP2 via the IQ-PIP-USP2 Adapter.

Specifi cations
General
Internal Controls: An 8-segment DIP switch
sets the IQ address (decimal range: 1–250).*
A 4-segment DIP switch sets input and output
sensitivity/gain. A Reset/Preset switch, accessible with a straightened paper clip through
the PIP panel, selects the next user preset if
pressed for less than 2 seconds, resets the
PIP to preset “0” if pressed for more than
2 seconds, or re-writes from fi rmware to
fl ash memory restoring all settings to factory
default if pressed while applying power. Jumpers select thru or processed signal for daisy
output of each channel.
* If address “0” is selected, the IQ-PIP-USP2 will operate
in stand-alone mode. In this mode, the Crown bus port is
deactivated.
Connectors: Crown Bus: RJ-45 connector for
input/output, RJ-45 connector for daisy output.
Features
• 24-bit analog to digital conversion, and
24/48 bit DSP processing.
• Free IQ for Windows software provides easy
setup and monitoring of all IQ-PIP-USP2
parameters.
• Up to seven different fi lter types are avail-
able for a total of 16 fi lters on-board.
• Greater than one half-second of delay available per channel.
AUX In/Aux Out/Listen Bus: RJ-11 connector.
Audio Input: Balanced 3-pin female XLR connector for each channel. Audio “Daisy Chain”
Output: Balanced 3-pin male XLR connector for
each channel.
Indicators: A yellow DATA indicator fl ashes
when a valid IQ command is received from
the IQ System via the Crown Bus. The DATA
indicator can be forced on to facilitate rapid
troubleshooting of Crown Bus wiring. A green
PRESET indicator fl ashes to indicate the user
preset number currently selected in memory.
If the PRESET indicator does not fl ash the
preset number when selected, this indicates
the preset has been modifi ed by the user.
Memory Backup: 1 Mbyte non-volatile FLASH
memory for backup of run-time parameters,
presets, and program storage. Capable of
80,000 writes minimum.
Power Requirements: Power draw: 240 mA
@ +24 VDC and 65 mA @ –24 VDC. When
installed into a Crown PIP-compatible ampli-
fi er, the unit receives ±24 VDC from the ampli-
fi er. No external power is required.
Total Power Dissipation: 7.4 watts.
Crown Bus Data Communication
Protection: If communication is lost, the unit
will continue to function with the last commands received.
Data Rate: 38.4 K BAUD.
Data Format: Serial, binary, asynchronous; 1
start bit; 1 stop bit; 8 data bits; no parity.
Crown Bus Interface Type: Optically isolated
20 milliamp serial loop.
Operation: Half duplex.
Transmission Distance: Variable from 200 to
• User-selectable presets for easy recall of
settings.
• Load supervision for real-time warning of
load problems.
• Listen Bus allows easy connection to an audio
monitoring system.
• Reliable FLASH memory backs up all parameters.
• The best three-year “No-Fault” full warranty
in the business!
3000 feet (61 to 914 m), depending upon wire
capacitance. Typically 1000 feet (305 M) using
shielded twisted-pair wire, #26 AWG or larger.
Can be extended with an IQ Repeater.
