TROUBLESHOOTING

PROBLEM:

1. Front panel DISPLAY blinks: THERMAL WARNING.

If the ZR-6 MultiZone Receiver has an inappropriate speaker impedance load or inadequate ventilation, the system will continue to work, but with a warning that a fault needs to be corrected. Other fault indicators include: blinking front panel zone LED(s) corresponding to the faulted zone(s) and blinking source and mute keys on the keypads.

SOLUTION:

•Check that the speaker impedance in all zones is not below 4 ohms per channel. If four speakers are to be connected in a zone, they must be 8 ohm speakers connected in parallel.

•Check to make sure there is adequate space above the ventilation holes on the top of the ZR-6 MultiZone Receiver. A Niles FM-1 (FG01215) or FM-1R (FG01214) System Cooling Module may be necessary in installations where ventilation is limited.

PROBLEM:

2. No sound (All Zones)

Front panel DISPLAY blinks: THERMAL PROTECTION.

If the ZR-6 MultiZone Receiver has an inappropriate speaker impedance load or inadequate ventilation, eventually the entire system will turn off. Other fault indicators include:

a blinking front panel zone LED(s) corresponding to the faulted zone(s) and blinking source and mute keys on the keypads.

SOLUTION:

•Check that the speaker impedance in all zones is not below 4 ohms per channel. If four speakers are to be connected in a zone, they must be 8 ohm speakers connected in parallel.

•Check to make sure there is plenty of space above the ventilation holes on the top of the ZR-6 MultiZone Receiver. A Niles FM-1 (FG01215) or FM-1R (FG01214) System Cooling Module may be necessary in installations where ventilation is limited.

PROBLEM:

3a) No sound from both channels (One or More Zones) Front panel DISPLAY blinks: ZONE (X) LSPKR SHORT or ZONE (X) RSPKR SHORT.

3b) Sound from only one channel (One or More Zones)

Front panel DISPLAY blinks: ZONE (X) LSPKR OK or ZONE (X) RSPKR SHORT.

If a speaker wire has a short circuit, the shorted channel(s) of the ZR-6 MultiZone Receiver will shut down. Other fault indicators include: blinking front panel zone LED(s) corresponding to the faulted zone(s) and blinking source and mute keys on the keypads.

SOLUTION:

•Turn the entire system off using the main power switch on the front of the ZR-6 MultiZone Receiver.

•Check for shorts and repair/ replace the speaker wire.

•Turn the system on using the main power switch.

PROBLEM:

4. No Sound (One or More Zones).
