—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.
Programmable
Input Processor (P.I.P.)
P.I.P.-ISO is designed especially for 25 to 140 volt dis-
tributed systems where UL
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.

Input Processor
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.
For more information on these or other P.I.P.s under
development, contact your local dealer or Crown's Tech-
nical Support Group.
