INSTALLING THE AVA7

Installation of the AVA7 is a straight- forward process.

IMPORTANT:

The amplifier must be installed following the directions described below. To ensure adequate perform- ance and safety, never install the amplifier with less free space around the amplifier than what is specified.

Always put amplifiers on the bottom of a stack.

Heavy equipment should not be sup- ported solely by the front-mounting locations. It is recommended that addi- tional rear support be used.

1.The JBL Performance Series AVA7 power amplifier has been designed to be mounted in EIA standard racks, or stacked freestanding as long as there is 4 inches (10cm) of free space around the amplifier (sides and rear). If the AVA7 is being mounted in a rack, it is suggested that its feet be removed prior to installation. If the AVA7 will be stacked with other components, use the feet that came attached to the unit. This will ensure that there is suf- ficient air space underneath so that heat can be dissipated effectively. Two rack ears are included with the AVA7. To install these rack ears, remove the four machine screws on each of the two side panels (see drawing), hold each rack ear in place, and attach it to the AVA7 using the same four screws. Make sure that these screws are securely tightened.

2.Make sure that the amplifiers are located in a well-ventilated, cool area. Be certain that the side and rear panels are not obstructed, as the cooling fan brings air in from the rear and expels it at the sides. It is very important not to obstruct the airflow from the rear panel; heat buildup and premature failure may occur. If the amplifier is installed inside a cabinet that is enclosed on all sides, the front of the cabinet must remain open to allow sufficient flow-through ventilation to avoid overheating.

3.Using a helper to guide the unit into the rack, gently slide the AVA7 into place. Align the rack mounting holes to the rack ears of the equipment rack.

4.Starting with the bottom two screw holes and using two of the rack screws and plastic washers (if sup- plied with your rack), secure the AVA7 into the rack. It may be neces- sary to have a helper hold up the rear of the unit until you have started the threads of the screws. Once the
