IQ-PIPUSP2/CN
ULTRA SERIES
hen installed in Crown’s Com-Tech
10 Series and Macro-Tech 02 Series
amplifi ers, the IQ-PIP-USP2/CN cre-
W
ates the industry’s fi rst CobraNet™ compatible
amplifi er. The module integrates the latest
CobraNet™ audio-networking technology and
a full complement of audio signal processing
in a package that requires ZERO rack space!
In addition, the IQ-PIP-USP2/CN connects the
amplifi er to the IQ Bus of an IQ System, allowing the amplifi er to be controlled and monitored
via IQ.
The IQ-PIP-USP2/CN offers an extensive list
of features, including output signal delay for
precise acoustic alignment, auto standby for
reduced energy costs, plus eight independent,
fully adjustable fi lters per channel.
The IQ-PIP-USP2/CN also provides on-screen
error reporting of fault, high temperature,
and excessive distortion, so you can know
quickly if any changes occur in your amplifi er’s
status. Meanwhile, the IQ-PIP-USP2/CN’s realtime load supervision feature ensures you will
be notifi ed immediately of any changes to the
load.
Offering crisp, clear sound and the wide
dynamic range possible with full 24-bit converters, the IQ-PIP-USP2/CN provides unprecedented power and fl exibility in one compact—
and very affordable—module.

* You must have a PIP2-compatible amplifi er to use the
IQ-PIP-USP2/CN. To determine if your amplifi er is PIP2compatible, look for the PIP2 logo on the back of the
amplifi er. The IQ-PIP-USP2/CN is NOT compatible with
older Crown PIP amplifi ers.
Specifi cations
General
Internal Controls: An 8-segment DIP switch
sets the IQ address (decimal range: 1–250).* 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.
* If address “0” is selected, the IQ-PIP-USP2/CN will operate
in stand-alone mode. In this mode, the IQ Bus port is deactivated.
Connectors: IQ Bus: RJ-45 connector for input/
output, RJ-45 connector for daisy output.
AUX In/Aux Out: RJ-11 connector. CobraNet™
Audio Input and Output: RJ-45 connector for
Primary Network, RJ-45 connector for Secondary Network.
Features
• Receives any two of 64 channels on a
repeater-based CobraNet™ network, or any
two of up to 3000 channels on a switch-based
CobraNet™ network.
• Transmit channels are user-selectable from
16 bit to 24 bit.
• Sends “Listen-Bus” amplifi er output monitor
signals via CobraNet™.
• Implements dual-redundant network ports
for the ultimate in robust audio networking.
• 24 bit analog to digital conversion, and 24
bit, 48 kHz DSP processing.
• Free IQ for Windows software provides easy
Indicators: A yellow DATA indicator fl ashes
when a valid IQ command is received from the
IQ System via the IQ Bus. 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). Two dual-color
indicators provide status of the CobraNet™ network. The left indicator on the Primary and
Secondary RJ-45 connectors fl ashes green if
the network link is connected and operating
normally, and fl ashes red if the port is in a
“Fault” condition. The right indicator on the Primary and Secondary RJ-45 connectors is ON
green if the port is “in-use,” and is ON orange
if the port is operating as the CobraNet™ “Conductor.”
Memory Backup: 1 Mbyte non-volatile FLASH
memory for backup of run-time parameters,
presets, and program storage. Capable of
greater than 10 year data retention and estimated 20+ year life-cycle.
Power Requirements: Power draw: 410 mA
@ +24 VDC and 40 mA @ –24 VDC. When
installed into a Crown PIP2-compatible ampli-
fi er, the unit receives ±24 VDC from the ampli-
fi er. No external power is required.
Total Power Dissipation: 10.5 watts.
IQ 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.
IQ Bus Interface Type: Optically isolated 20
milliamp serial loop.
Operation: Half duplex.

parameters.
• Up to seven different fi lter types are available
for a total of 16 fi lters on-board.
• Signal delay and compressor/limiter for each
channel.
• User-selectable presets for easy recall of
settings.
• Load supervision for real-time warning of
load problems.
• Reliable FLASH memory backs up all parameters.
• The best three-year “No-Fault” full warranty

Transmission Distance: Variable from 200 to
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.
