TROUBLESHOOTING

The AV2 does not power on.

1. Make sure the rear panel Power switch is set to the ON position.

2. Attempt to power on the AV2 with the front panel Standby

button and remote control On button.

3. Examine the power cord to ensure a good connection between

the rear panel AC input connector and the wall outlet.

4. Check the electrical circuit and breaker.

The remote control does not work.

1. Make sure that the remote control touchscreen is in the “JBL”

or “Zone 2” menu layers. The remote control is a universal

control designed to operate all of the home theater equipment

in your system. In order to control the AV2, the remote control

must be in the “JBL” or “Zone 2” menu layers. 

2. Eliminate obstructions between the remote control and the

front panel IR receiver. When the rear panel IR IN connector is

not in use, the remote control must be in line of sight with the

front panel IR receiver for proper operation. The remote control

might also become unreliable if strong sunlight or fluorescent

light is shining on the AV2’s IR receiver.

3. Make sure the remote control batteries are correctly inserted

with the proper polarity.

4. Replace the remote control batteries. When the batteries are

low on power, the remote control enters a low-voltage

condition that prevents it from operating the AV2.

5. If using the optional RF-1 receiver, ensure that it is properly

connected to the AV2 rear panel.

The AV2 is powered on, but there is no audio.

1. Make sure that the source device is powered on, playing audio,

and set to the right output connector.

2. Make sure the volume level is audible. Volume level can be

adjusted with the front panel volume knob or the remote

control VOL 

 and 

 buttons.

3. Make sure the audio has not been muted. The message “MUTE

ON” is displayed on the on-screen and front panel displays

when audio has been muted in the Main Zone. In addition, the

MUTE button on the front panel lights red when the Main Zone

mute is active and green when the Zone 2 mute is active. If

both Zones are muted, the Mute button lights amber. To

deactivate mute, press the Mute  button or adjust the volume

level.

4. Verify that all rear panel input and output connections are

correct.

5. Check the INPUT SETUP menu, DIG AUDIO and ANLG AUDIO

parameters to ensure the appropriate audio connector is assigned

to the selected input.

6. Verify that the incoming audio signal is compatible with the input

chosen.

Note: The rear panel input connectors marked S/PDIF INPUTS (RCA

and TOSLINK connectors) are not compatible with MP3 sources.

The subwoofer(s) distorts frequently.

The likely cause for the subwoofer(s) to distort is either an

incorrectly set output level or the subwoofer high-pass filter is set

too low. Verify that the SUB/LFE LPF setting (subwoofer crossover

point) is set correctly. If correct, try setting the SUB HPF setting to a

higher value to resolve the issue. Refer to 

Section 3: Setup

 for more

information.
