The IT-42 is an output isolation transformer accessory for the

QSC CX302 amplifier, allowing it to drive two 25-, 70- and

100-volt distributed lines in stereo or parallel or a single 140-

or 200-volt line in bridged mono. The IT-42 is pre wired for

quick and convenient mounting to the back of the CX302

amplifier and requires no additional rack space.
