—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

EMI (Electro-Magnetic Inter-
ference) shielding provides
additional gain margin under
fault conditions.
Balanced inputs with 1 kVAC
breakdown 1:1 isolation
transformers.
Excellent common mode
rejection.
RFI filter which attenuates
unwanted ultrasonic
frequencies that would
otherwise waste amplifier
power. The RFI filter is a
12 dB/octave (2nd order),
Bessel-tuned low-pass filter
with a 3 dB roll-off point at
33 kHz.
Switchable subsonic/bass filter
with 50, 100 or 300 Hz roll-off
frequencies.
Quick-connect barrier block
connectors provide greater
wiring flexibility and make
installation easier.
