INSTALLATION: RACK MOUNTING AND MOUNTING DIMENSIONS

Before installing into equipment rack: ensure that all side-access DIP switches and crossover SIPs are setup as desired. They will be impossible (or extremely difficult) to change after the amplifier is installed in the rack. The side cover plate should be installed to keep dust and foreign material out of the chassis.

Securing the Front Ears to the Rack Rails

Use four screws and washers when mounting the PL2A amplifier to the front rails. Support the weight of the amplifier while securing it to the rails to avoid bending or distorting the front rack mount ears.

Supporting the Rear of the Amplifier

Supporting the amplifier at the rear is important, especially for mobile and touring use. Rear rack mounting ear kits are an accessory item and are available from QSC’s Technical Services Department or from your dealer or distributor.

The rear rack mounting ear kit may be installed in two different ways.

Method 1- The amplifier is first installed from the front of the rack and then the ears are secured directly to the amplifier with two machine screws as shown, left. Then the ears are secured to the rails using ordinary rail hardware.

Method 2- The amplifier is first installed from the front of the rack. Then, the accessory rear ears are positioned on the rear rack rails and secured. The pin installation position can now be selected. Install the pin so that it fits well into the slot provided on the amplifier's rear mounting tab.
