CAMBRIDGE AUDIO 540R V3

A low hum or buzz sound can be heard:

Power cords or lighting placed near this product.
Analogue inputs not connected securely.

Sound is not audible from one channel:

Speaker connections disconnected.
Speaker set to ‘None’ in OSD setup menu.

Sound cuts off when listening to music or there is no sound even though power is ON:

Speaker impedance is less than prescribed for the 540R V3.
The unit is not adequately ventilated and may be overheating.

Low bass or “phasey” response:

Speaker polarity (+/-) of one or more speakers is reversed.

An unusual hissing noise is heard when listening to a radio broadcast in stereo, but not heard when
listening in mono:

A slight noise may be heard because the method used for modulation of FM stereo broadcasts is different than that used for mono broadcasts.
Aerial quality also effects the level of the hiss heard.

Noise is excessive in both stereo and monaural radio broadcasts:

Poor location and / or direction of the antenna.
Transmitting station is too far away.

No sound from the rear speakers:

Source being played is not recorded in surround sound.
Speaker/s set to ‘None’ in OSD setup menu.
A stereo mode has been selected.

No sound from the centre speaker:

Centre speaker has been set to ‘None’ in OSD setup menu.
A stereo mode has been selected.

No sound from the subwoofer:

Sub has been set to ‘OFF’ in the OSD setup menu or via the remote.
DTS Neo:6, DD PLII modes (which have no LFE channel) have been selected with all speakers set to ‘Large’ and Bass Augment off.

Remote Control is not working:

The batteries are flat.
The remote is too far from the receiver or out of the effective range.

No sound from speakers when connected to a digital input:

Audio input type is set to analogue (check display). Press the Audio in Type button to switch to digital.

No sound from speakers when connected to an analogue input:

Audio input type is set to digital. Press the Audio in Type button to switch to analog (check display).
Audio input type can also be set in the Input Setup menu of the OSD.

OSD not visible:

Check that the TV/Monitor is connected to the 540R V3 and is using a Composite or S-Video connection.
