1.1 Features
❏ Fail-safe output isolation allows
either side of outputs to be
shorted to chassis ground with
no worries.
❏ 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.
