Troubleshooting
No lights are illuminated
Please check the following items if no lights are illuminated on the P1000 when you think that it should
be switched on.
<
Is the power cord plugged into the P1000? Is the mains socket that it is plugged into switched on?
<
Has the plug fuse failed, or a circuit-breaker earlier in the power supply path opened?
<
Has the fuse in the rear panel (above the power inlet) failed? Note that the fuse must be
replaced with the same type: if you require assitance with this, please contact your dealer.
<
Is the power switch on the rear panel of the P1000 in the “on” position?
Red/amber light on the front panel
The table on page 10 gives details of the fault conditions indicated by different LED patterns, together
with suggestions on correcting the fault.
No sound is produced
Please check the following items if no audio can be heard through your P1000.
<
Are all the channel-indicator LEDs on the front panel green? Refer to the table on page 10 if you see
other colours, or above if nothing is illuminated.
<
Has the correct input been selected on the pre-amp. and is the selected source generating audio
(the disk is playing, for example)? If possible, try plugging headphones into the pre-amp. to ensure
that the audio is present at that point – if you cannot hear any audio through the headphones, then
it is likely that the fault is between the audio source and your pre-amp.
<
Is the volume on the pre-amp. turned up to a reasonable level? Is the pre-amp. muted?
<
Are the connections between your pre-amp. and the P1000 made as described earlier in this
handbook? Check also the connections between the P1000 and the speakers.
Sound is poor or distorted
If the sound coming from your P1000 is distorted, or is weak in some way (lacking in bass), please
check the following items.
<
Ensure that all cables (both interconnects and speaker cable) are making a good connection. Turn
the P1000 off, withdraw each cable from the connector and plug it back in again. Switch the P1000
back on to see if the sound quality has improved.
<
Check that you have selected the correct size of speakers to suit your system in the setup menu
of the processor or pre-amp. Setting speakers to “Small”, for example, may be the cause of weak
bass. See the handbook of your pre-amp./processor for details.
Sound comes only from some of the speakers
If sound is coming from some speakers only (but those speakers are operating normally), please check
the following items.
<
Are all speakers in the system connected to the P1000?
<
Have you congured your pre-amp. to include all the speakers in your system? See the handbook of
your pre-amp./processor for details.
<
Do you have an appropriate surround-sound source selected and playing through the pre-amp?
<
For sources connected digitally to the pre-amp., check that the source is putting multi-channel data
out. Some DVD players (for example) allow selection of the output format and also whether multi-
channel data is down-mixed to PCM (stereo). See the handbook of your source for details.
<
Ensure that the disc you are playing is a multi-channel recording and that the processor is putting
multi-channel audio out.
<
Check that your speaker balance is correct (see your pre-amp./processor handbook for details).
<
Are all the channel-indicator LEDs on the front panel green? Refer to the table on page 10 if you see
other colours.
Hum on an amplier output
If you have a “hum” coming from one of the speakers, please check the following items.
<
Does the hum originate from a ground loop caused by an aerial, satellite dish or cable supply (if the
aerial is disconnected, does the humming stop)? Please contact your dealer or aerial contractor for
further advice.
<
Ensure that the interconnect and speaker leads are not wrapped around a mains lead.
<
Try switching the ground lift on the pre-amp./processor, if available (see the handbook of your pre-
amp. for details).
See also “Sound is poor or distorted”, above.
There is radio/television reception interference
If you nd that radio or television interference is present when the P1000 is switched on, but disappears
when it is switched off, ensure that the aerial/dish cable to your TV or receiver is routed away from your
P1000 and its cabling, and that the cabling used from the aerial/dish is of a high-quality (screened).
Repositioning the receiving aerial/dish may bring an improvement.
<
If you are unable to rectify the fault after checking the items suggested above, please
contact your dealer for advice.
