User manual CAMBRIDGE AUDIO A1 AMPLIFIER

[. . . ] Particular attention has also been paid to the quality of the passive components where close tolerance metal film resistors and audio grade signal coupling capacitors are used throughout. Critical line level circuits are also protected from electrical noise by our custom designed gold plated shielding cans. Some Cambridge Audio amplifiers also incorporate tone controls, which may be switched out of circuit in 'direct' mode for the shortest and therefore purest signal path. Other features include increased protection against accidental short circuits or sudden overload and dual sets of high current loudspeaker terminals for easy bi-wiring. [. . . ] If a 13amp (BS 1363) plug is used, a 3amp fuse must be fitted, or if any other type of plug is used a 3amp or 5amp fuse must be fitted, either in the plug or adaptor, or on the distribution board. 4 Amplifiers INSTALLATION Please take a moment to read these notes before installing your amplifier, they will enable you to get the best performance and prolong the life of the product. Due to stray magnetic fields turntables should not be located nearby due to interference. Do not situate it on a rug or other soft surface and do not obstruct the air inlet and outlet grilles on the underside and top cover.

In the event, switch off immediately, disconnect from the mains supply and contact your dealer for advice. Do not route the power cable so that it can be walked upon or damaged by other items near it. Electronic audio components have a running in period of around a week (if used several hours per day). This will allow the new components to settle down, the sonic properties will improve over this time. Do not plug a source component directly into a power amplifier unless it has a variable output level. Never turn on a power amplifier when no control amplifier is connected. It is recommended that when bi-amping, the same type power amplifiers are used. If you do not intend to use this unit for a long period of time, switch it off and unplug it from the mains socket.
