INTRODUCTION

The IT-42 is an output isolation transformer accessory for the QSC CX 302 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. It mounts conveniently to the back of the amplifier and requires no additional rack space.

In stereo or parallel modes, the two distributed lines may be loaded at up to 400 watts each. In bridged mono, the distributed line may be loaded at up to 800

watts.

INSTALLATION

Although the IT-42 transformer accessory can be installed while the amplifier is already rack mounted, installation is much easier with the amplifier out of the rack

and placed face-down so it rests on its front panel.

CAUTION: Turn off the amplifier before installing the IT-42 accessory.

1. Open the safety shroud over the amplifier’s output barrier strip. Fully loosen—but do not remove—the two screw terminals at the top and the two at the bottom.

2. Align the spade lug connectors on the transformer input wires with their respective screw terminals and slide them fully onto the screws. Tighten

the screw terminals.

3. Insert the slotted mounting tabs on the right end of the IT-42 into the slots in the amplifier chassis (Figure 2).

4. Align the holes in the mounting tabs on the left end of the IT-42 with the threaded holes in the amplifier chassis. Insert and tighten the

mounting screws.

5. Press the right end of the bracket in to the left so that the slotted tabs lock to the amplifier and will not pull out (Figure 3).

Rack mounting

The IT-42 adds to the depth of the amplifier, so you

must allow more space at the rear of the rack. See

Figure 4. Because of the additional weight of the

transformers, it is important to support the amp at the

back, even in fixed installations. Rear rack ear kits for QSC

amplifiers are available from QSC’s technical services

department or from your dealer or distributor.

If you are using in the same rack two or more

amplifiers with transformer accessories, separate

them by at least one rack space to minimize crosstalk.
