IQ-PIP-USP2 is an IQ2 -series component. This means it
supports Crown’s UCODE protocol and requires an IQ
System with an IQ2-compatible IQ interface. UCODE
(universal code) enables users and third parties to
develop custom software objects to control and monitor
IQ2-compatible components like the IQ-PIP-USP2.
P.I.P.-AMCb combines many of the features found in the
P.I.P.-XOV and P.I.P.-CLP to provide both a variable 4th-
order Linkwitz-Riley crossover and an IOC-driven or vari-
able-threshold signal-driven compressor. In addition, vari-
able equalization networks provide for “constant-directiv-
ity” horn equalization and filter-assisted B6 vented bass box
equalization. Bi-amping and tri-amping capabilities are pro-
vided via XLR connectors.

P.I.P.-ATNJ includes the features of the P.I.P.-FXT (balanced
Jensen
®
1:1 isolation transformers) and adds to each chan-
nel a 12-dB/octave RFI filter, a variable 18-dB/octave high-
pass filter (to reduce bass/subsonic frequencies), and a 6-
dB/octave 3-kHz shelving network for “constant-directivity”
horn equalization. Special quick-connect barrier blocks are
provided for inputs to each channel. Also adds a Jensen
®
32-step precision attenuator to each channel.
P.I.P.-BEQC adds many features of the Bose
®
Controllers
to the input of your amplifier. Each channel includes a cus-
tom equalization network for Bose loudspeakers. Also in-
cluded is a bass-cut (high-pass) filter for each channel.
The equalization and bass-cut filters can be bypassed, if
desired. Balanced inputs and “daisy-chain” outputs use
removable barrier block connectors for quick, solderless
connections.
P.I.P.-BEQX Same as P.I.P.-BEQC but with XLR connec-
tors.
P.I.P.-CLP is designed to detect and prevent overload. The
same error detecting circuit that is used to signal the IOC
indicator is used to activate this error-driven compressor. It
is not a typical signal-driven compressor, but a circuit to
prevent any overload. It can yield up to 13 dB or additional
signal safety margin without noticeable program change.
P.I.P.-EDCb State-of-the-art programmable error-driven and
signal-driven compressor plus a variable high-pass filter
for each channel. Fast or slow attach and release times can
be set independently for each channel.
P.I.P.-FXT uses balanced 1:1 transformers to isolate the
source from the inputs. It comes with balanced female 3-
pin XLR connectors.
P.I.P.-FMX facilitates “daisy-chaining” several amplifier bal-
anced inputs together. Female to male 3-pin XLR connec-
tors are used to passively bridge the amplifier inputs.
P.I.P.-FMXT Same as P.I.P.-FMX but includes input trans-
formers.
