—WARNING—
THIS P.I.P. PROVIDES FULL ISOLATION
FOR ISO-MODIFIED AMPLIFIERS ONLY!
DO NOT CONNECT THE OUTPUT GROUND

P.I.P.-ISO
is designed especially for 25 to 140 volt dis-
tributed systems where UL
®
-listed isolation is required.
Installation 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.-XOV
is a versatile 18 dB/octave mono crossover/
filter with biamping and triamping capabilities.
P.I.P.-FMX
facilitates “daisy-chaining” balanced ampli-
fier inputs. Female to male three-pin XLR connectors
are used to passively bridge the inputs.
P.I.P.-FXQ
makes it easy to connect audio sources that
have phono (RCA) connectors. It includes two balanced
three-pin female XLR connectors, and two female phono
jacks for quasi-balanced or unbalanced operation.

P.I.P.-PA
adds a switchable balanced low-impedance
mic input, a balanced line-level input and a compressor
to each channel. Remote switching circuitry provides
quick and quiet fades from mic to line and back.
P.I.P.-102
is a two-channel module providing equaliza-
tion based on the BOSE
®
102 controller. Screw terminal
plugs provide balanced connections. Each input chan-
nel has an output from the
P.I.P. that can be indepen-
dently configured for output with no processing, 102
equalization or 102 equalization with bass-cut.

P.I.P.-RPA
adds the features of a 4x2 mixer to your am-
plifier. Its four inputs accept mic- or line-level input. It
offers priority switching (“voice-over”) of each input and
remote level control with the RPA-RMT. Other features
include bus inputs and outputs, adjustable input sensi-
tivity, phantom power and RFI suppression. Input isola-
tion transformers are optional.

der development, contact your local dealer or Crown’s
Technical Support Group.
