Operating the ZR-4 MultiZone receiver

Play Sources 2-4

1.Pressing any of these source keys will turn on the zone and allow you to listen to the source connected to that input at the preset start volume.

2.Additional control over the source’s functions is available using the R-6L Remote Control.

3.The 12V out on the rear panel of the ZR-4 MultiZone Receiver and the Keypad will become active.

4.Pressing the Off key will turn off the zone. The 12V output on the rear panel becomes inactive if all other zones are off.

Troubleshooting

PROBLEM:

1. Front panel Display blinks: THERMAL WARNING.

If the ZR-4 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 (see page 14) above the ventilation holes on the top of the ZR-4 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-4 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-4 MultiZone Receiver. A Niles FM-1 (FG01215) or FM-1R (FG01214) System Cooling Module may be necessary in installations where ventilation is limited.

Party Mode

1.Pressing-and-holding any of the Source Keys on a Keypad for 3 seconds will initiate the Party Mode. This feature turns all enabled zones on to that source at the programmed party volume level. If the zone is already on, no volume level change will take place. Volume control, bass and treble are still independent in each zone.

2.The 12V out on the rear panel of the ZR-4 MultiZone Receiver and the enabled Keypads will become active.

3.Pressing and holding the Off button for 3 seconds in any zone will turn off all zones. All 12V outputs become inactive.

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-4 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-4 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).

Front panel DISPLAY blinks: AMPLIFIER FAILURE.

The output chip has acted to protect itself from potential damage. Other fault indicators include: blinking front panel zone LED(s) and blinking source and mute keys on the keypads.

• Call Niles Tech Support

PROBLEM:

5. No sound (All Zones).

Front panel DISPLAY blinks: POWER FAILURE.

The output chip has acted to protect itself from potential damage. Other fault indicators include: a blinking front panel zone LEDs and blinking source and mute keys on the keypads.
