It has been developed following an extensive research and development program that has culminated in what we regard as an exceptional mid-range hi-fi product. Our aim when designing this product was to produce a visually appealing unit which would look comparable to higher priced products, and give an exceptional performance to match. We trust that this amplifier will give you hours of listening pleasure, and provide years of unparalleled performance. [. . . ] In the event of this happening, disconnect the wall plug form the mains supply immediately, and contact your local dealer for service advice. Do not position the power cable such that it can be walked upon, or damaged by regular traffic. Ensure that all other interconnecting cables such as speaker cables or ancillary equipment leads, are stowed safely behind the unit, and cannot be easily snagged or kicked thus causing possible damage to the unit. Ensure that all interconnetion cables have been fitted correctly, and that polarity has been maintained. This is especially important when connecting loudspeakers to this amplifier. On the rear panel, binding post speaker outputs are provided. These are coloured red for positive, and black for negative. There will be a corresponding pair of terminals on the rear of suitable loudspeakers. These terminals should be connected together with adequate quality speaker cables, taking care that the red terminal on the amplifier is connected to the red terminal on the loudspeaker. The same process should occur for the black terminals. Care should be taken to ensure that no wires have become frayed during this process, and subsequently could be touching each other. This will cause a short circuit on the output stage of the amplifier, and will result in a poor or distorted sound. Failure to rectify this problem may result in long term damage to this unit. Position the loudspeakers a suitable distance away form the amplifier, gaining enough distance to allow the stereo image to be achieved. Having the loudspeakers too close to each other will not allow you to fully define the stereo content of music played through the system, plus may result in poor sound due to the cancellation properties that sometimes exist when in this state. It is not ideal to place loudspakers in the corners of a room as this will normally colour the audible content of the music with a lift in bass content. Although it is sometimes desirable to increase the bass response of your system, this can lead to a `boomy' bass which is not always desirable, and can be hard to control. It should also be noted that firing loudspeakers onto a hard flat surface can cause mid range and high frequency colouration as reflected sound becomes part of the audible sound. This can lead to a harshness, or dead spots through cancellation. The best sound is always subjective to the listener, therefore we suggest you arrange your hi-fi to suit your own listening tastes, and sit back and enjoy the fruits of your labour. 5 MAKING THE CONNECTIONS 6 USING THE AMPLIFIER When you unpack the amplifier from the box, all music settings will be at default values. These can be altered according to your listening tastes; these new settings will be retained within the memory of the amplifier and will remain set even after switchiing off this system. Changing the input listening source This amplifier is fitted with 6 inputs for connections to the following external equipment: · Phono (turntable) · Tuner (AM + FM) · Tape / Aux line input source · CD · DVD (stereo only) · DAB tuner These will be connected to the rear panel as indicated in the connection diagram on the previous page. To change which input source is listened to, press once the switch below the corresponding piece of equipment which is required. [. . . ] To reactivate the loudspeaker control it will be necessary to press the function button again five times. 13 CARE AND MAINTENANCE To clean the amplifier, wipe the case with a slightly moist lint-free cloth. Do not use any cleaning fluids containing alcohol, ammonia or abrasives. Do not spray a aerosol at, or near, the amplifier. Always use original packaging if it is necessary to transport the unit at any time. [. . . ]
