GENERAL GUIDANCE
DO NOT connect the mains power to any signal input terminal.
DO NOT change any connections without first switching off the power to all the components in your AV system.
ALWAYS turn down the system master volume control before turning the equipment on or off.
DO NOT use your amplifier at its maximum volume setting. The resulting distortion may damage your loudspeakers and subwoofer. The position
of the Volume Control on your amplifier is NOT a reliable guide as to ‘how loud’ your equipment will play. Allow your system ample ‘headroom’.
Do not operate your subwoofer closer than 450mm from the TV to avoid distorting the colour picture. if this occurs, switch the TV set off. After 15 minutes switch on again: colour balance should now be restored.
To minimise hum and mains interference ensure that low level (line level) signal cables are well screened. Avoid routing
