Crown IQ-PIP-USP2 User manual

IQ-PIP-
USP2/CN
ULTRA SERIES
When installed in Crown’s Com-Tech
10 Series and Macro-Tech 02 Series
amplifiers, the IQ-PIP-USP2/CN cre-
ates the industry’s first CobraNet™ compatible
amplifier. 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
amplifier to the IQ Bus of an IQ System, allow-
ing the amplifier 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 filters 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 amplifier’s
status. Meanwhile, the IQ-PIP-USP2/CN’s real-
time load supervision feature ensures you will
be notified immediately of any changes to the
load.
Offering crisp, clear sound and the wide
dynamic range possible with full 24-bit con-
verters, the IQ-PIP-USP2/CN provides unprec-
edented power and flexibility in one compact—
and very affordable—module.
For more details about the Crown
IQ-PIP-USP2/CN, contact the Crown Technical
Support Group at 800-342-6939 or
219-294-8200. Also, visit the Crown Audio
website at www.crownaudio.com.
* You must have a PIP2-compatible amplifier to use the
IQ-PIP-USP2/CN. To determine if your amplifier is PIP2-
compatible, look for the PIP2 logo on the back of the
amplifier. The IQ-PIP-USP2/CN is NOT compatible with
older Crown PIP amplifiers.
Specifications
General
Internal Controls: An 8-segment DIP switch
sets the IQ address (decimal range: 1–250).* A
Reset/Preset switch, accessible with a straight-
ened 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 deacti-
vated.
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 Second-
ary Network.
Indicators: A yellow DATA indicator flashes
when a valid IQ command is received from the
IQ System via the IQ Bus. A green PRESET indi-
cator flashes to indicate the user preset number
currently selected in memory (if the PRESET
indicator does not flash the preset number
when selected, this indicates the preset has
been modified by the user). Two dual-color
indicators provide status of the CobraNet™net-
work. The left indicator on the Primary and
Secondary RJ-45 connectors flashes green if
the network link is connected and operating
normally, and flashes red if the port is in a
“Fault”condition. The right indicator on the Pri-
mary 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™“Con-
ductor.”
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 esti-
mated 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-
fier, the unit receives ±24 VDC from the ampli-
fier. 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 com-
mands 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.
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.
Audio
Please note: The audio specifications are referenced to 0.775
