Troubleshooting

NO LIGHTS ON THE UNIT

Check that:

the power cord is plugged into the P7 and the mains socket outlet it is plugged into is switched on.

the plug fuse has not failed, or a circuit-breaker earlier in the power supply path has not opened.

the power button is pressed in.

RED LED PRESENT

Refer to the ‘Fault Status Indicators’ table if you have an unusual sequence of LEDs.

NO SOUND IS PRODUCED

Check that:

the correct input has been selected on the pre-amp.

you have assigned the digital input to the correct input source.

the volume is turned up to a reasonable level and ‘MUTE’ is not displayed on the front panel display on the pre-amp.

your power amplifier(s) are turned on and working correctly.

SOUND IS POOR AND BADLY DISTORTED

Check that:

all cables are making a good connection. If necessary withdraw the cable from the connector and plug it back in again. (Turn the power off before doing this.)

you have selected the correct size of speakers to suit your system in the setup menu of the processor or pre-amp.

SOUND ONLY COMES FROM SOME OF THE SPEAKERS

Check that:

all speakers in the system are connected to the P7.

you have configured your pre-amp to include all the speakers in your system.

you have an appropriate surround sound source selected and playing through the pre-amp.

for digital sources, check the player is outputting multichannel data. With some DVD players you are able to select in what format multi-format encoded discs are outputted, and whether multichannel data is down mixed to PCM (stereo).

the disc you are playing is a multichannel recording and that the processor is outputting multichannel audio.

your speaker balance is correct.

all amplifiers are turned on and all channels are working correctly.

all units are turned on. If the audio is ‘daisy-chained’ from the P7, make sure that the unit being fed is turned on.

HUM ON AN AMPLIFIER OUTPUT

Check that:

all cables are making a good connection. If necessary withdraw the cable from the connector and plug it back in again. (Turn the power off before doing this.)

if the hum originates from a ground loop caused by an aerial, satellite dish or cable supply, you should contact your aerial contractor.

the signal (interconnect) leads are not wrapped around a mains lead.

try switching the ground lift on the back panel of the processor (if available).

THERE IS RADIO/TELEVISION RECEPTION INTERFERENCE

The P7 has been designed to a very high standards of electromagnetic compatibility.

Check that:

the aerial/dish cable is routed as far as possible from your P7 and its cabling.

the cabling used from the aerial/dish is of high quality and screened.

repositioning the receiving aerial/dish as far as possible from your P7 and its cabling may bring an improvement.

if the problem persists, contact your aerial contractor.

you are using high quality screened audio cable between your equipment and that no cables are broken or damaged.
