INSTALLATION: UNPACKING & RACK MOUNTING

What is Included

Your CX168 shipping container, as shipped from the factory, includes:

-CX168 eight channel audio power amplifier

-this user’s manual

-security cover (plate) for gain controls

-self-adhesive rubber feet (use for non-rack mount applications)

-eight 3-pin terminal block input connectors

-two 8-pin terminal block output connectors

-#14AWG IEC-type detachable power cord

Save the container and packing material so the amplifier may be shipped without damage if service is ever required. If the

original container is not available, be sure to use a strong shipping container with enough packing material to prevent the amplifier from being damaged in transit.

Rack Mounting

Use four screws and washers to secure the amplifier to the equipment rack rails. Support the weight of the amplifier while securing it to the rails to avoid bending or distorting the mounting ears. The amplifier may be used in an equipment rack or as a stand-alone unit. Rack mounting is optional. Self-adhesive rubber feet are provided for non-rack mount applications.

Supporting the Rear of the Amplifier

Unless the amplifier is being installed in its final, fixed location, we strongly recommend supporting the rear of the amplifier.

Supporting the rear of the amplifier is required for mobile and portable use. If the amplifier is to be transported in any way, install the optional rear rack mounting ear kit to support the rear of the amplifier. During transport, the shock loads encountered on the chassis and rack can easily damage an unsupported amplifier and the rack rails. With proper support, reliability is enhanced.

Rear rack mounting ear kits are an accessory item and are available from QSC’s Technical Services Department or from your dealer or distributor. Refer to the literature included with the rack mounting ear kit for installation instructions. Two methods of rear rack mounting ear attachment are possible; use the method that best suits you application.

Optional rear rack mounting ear attachment methods- refer to the rear rack mounting ear kit’s documentation for details
