P.I.P.–CLP detects and prevents overload. Its compressor is
driven by the amplifier’s built-in IOC error detection circuitry.
Unlike typical signal-driven compressors, it only compresses
the signal to prevent overload. It can deliver up to 13 dB of
additional headroom without being noticeable.

—WARNING—
THIS P.I.P. PROVIDES FULL ISOLATION
FOR ISO-MODIFIED AMPLIFIERS ONLY!
DO NOT CONNECT THE OUTPUT GROUND
LUG TO THE INPUT COMMON OR CHASSIS
GROUND. REFER TO P.I.P.–ISO OWNER’S
MANUAL FOR FURTHER INFORMATION.

P.I.P.–ISO is designed especially for 25 to 140 volt distrib-
uted systems where UL
®
-listed isolation is required. Installa-
tion requires minor amplifier modifications. With the P.I.P.–ISO
installed, the amplifier outputs are safely isolated from the
input terminals and the chassis.

P.I.P.–ATNB uses balanced 1:1 transformers to isolate the
amplifier from the input signal. It also includes 12 dB/octave
RFI filters, variable 18 dB/octave high-pass filters, and 6 dB/
octave 3 kHz shelving networks for “constant-directivity” horn
equalization. The module also includes a calibrated 21-step
precision attenuator for each channel. Screw terminal plugs
are provided for input.

P.I.P.–BEQ is a two-channel module providing equalization
for BOSE
®
loudspeakers. For example, the P.I.P.–BEQ can
be used in place of a BOSE 102 controller. Screw terminal
plugs provide balanced connections. Each input channel
has an output from the P.I.P. that can be independently con-
figured for output with no processing, loudspeaker equaliza-
tion or loudspeaker equalization with bass-cut.

P.I.P.–RPA adds the features of a 4x2 mixer to your amplifier.
Its four inputs accept mic- or line-level input. It offers priority
switching (“voice-over”) of each input and remote level con-
trol with the RPA–RMT . Other features include bus inputs and
outputs, adjustable input sensitivity, phantom power and RFI
suppression. Input isolation transformers are optional.
For more information on these or other P.I.P.s under
development, contact your local dealer or Crown’s
Technical Support Group.
