JBL AVA7 manual Operation and Controls

OPERATION AND CONTROLS

™

¡

1. Power Switch

Pushing this button is all that is required to turn on the AVA7 if it is not part of a JBL Performance Series system and the Main Switch § is in the On posi- tion. If the amplifier is used as part of a JBL Performance Series system, the Main Switch § and the front-panel push button Power Switch ¡ should both be left in the On position. The amplifier will then turn on when the surround processor is activated. See the descriptions of the Main Switch § and Trigger Jacks ¶ for more informa- tion on turning on the AVA7.

2. Standby Indicator

This indicator on the front-panel Power Switch ¡ will glow red when the amplifier is in the “standby” mode, whether operating as part of a JBL Performance Series system or not. When the AVA7 is in the “on” mode, this light will turn blue.

3.Input Jacks (Ch. 1 Through Ch. 7) Seven of the output signals from the JBL Performance Series AV1 digital processor are connected to the seven input jacks. We suggest the channels be assigned as follows:

Ch. 1	Right Rear
Ch. 2	Right Side
Ch. 3	Right Front
Ch. 4	Center
Ch. 5	Left Front
Ch. 6	Left Side
Ch. 7	Left Rear

4. Speaker Terminals

Connect the speakers to these termi- nals, following the normal convention; wire the “+” side of the speaker to the red terminal, and the “–” side to the

black terminal. Wire the speakers with the proper polarity; reversing any speaker’s connections will not damage either the speaker or the amplifier, but will result in poor low-frequency per- formance and imprecise imaging.

WARNING: Terminals marked with the flash symbol are hazardous when live. External wiring connected to those ter- minals requires installation by trained personnel, and the use of ready-made lead cords.

NOTE: The minimum load impedance that this amplifier can handle safely is 8 ohms per channel. Using lower imped- ance loads can damage the unit and will void your warranty!

Wire Run Length		Minimum Gauge
Up to 20'	(6m)	16
Up to 50'	(15m)	14
Up to 100' (30m)		12

5. External Fuses

The AC mains fuse is located on the back panel of the amplifier. This fuse will not blow unless the amplifier is asked to produce more power than its design allows for a prolonged period or to prevent excessive current draw that could damage internal components during a fault condition. The amplifier has been designed to operate under virtually all conditions. Even momentary short-circuiting of the output (speaker) connections will not ordinarily damage the output circuitry (although this will activate internal protection circuitry and could cause one or more of the channels to temporarily mute until the circuit automatically resets).

Fuse Replacement

To remove the fuse, turn off the power switch and disconnect the power plug from the AC mains. Remove the fuse holder by lifting up the latch at the bottom and pulling the holder out. When looking at the fuse holder as installed on the back panel, the fuse on the right hand side is the active fuse. The fuse on the left is a spare. Remove the fuse on the right side and visually inspect it to see whether it has opened; if it has, discard it and replace it with the spare glass fuse. Reinstall the holder, and reconnect the AC mains.

If after replacing the fuse the unit is inoperative, service is required; contact your JBL dealer.

WARNING: Always unplug the amplifier from the AC mains before removing any fuse.

IMPORTANT:

Never install a fuse that has a

higher rating than the one specified on the back panel of the amplifier or in the owner’s manual.

6. Main Switch

Place this switch in the On position at all times during normal use.

7.Trigger Input and Output Jacks When using the AVA7 amplifier in a JBL Performance Series system with the AV1 Digital Surround Processor, you will need to use the trigger cable set included with the AV1. Connect the DIN end of the cable to the Trigger Output DIN jack on the rear panel of the AV1, and connect the 1/8" (3.5mm) plug to the Trigger Input Jack ¶ on the rear panel of the AVA7.
