Congratulations on purchasing this Acoustic Solutions’ integrated amplier. It has been developed following an extensive
research and development program that has culminated in what we regard as an exceptional mid-range hi- 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 amplier will give you hours of listening pleasure, and provide years of unparalleled performance. As with any
new electrical product please be patient and allow at least 36 hours use before all components have acclimatised themselves
to your surroundings, and found their optimum working temperature. Please do not operate this product at high volume levels
immediately after switching on.

INSTALLATION AND POSITION
This amplier should be positioned on a at stable surface. We would recommend that the position of your hi- equipment should be chosen carefully to
provide adequate protection for this device, but also provide an attractive showcase for your investment. Hi- equipment is not designed to be moved often,
therefore it is recommended that a permanent home for your hi- be achieved as soon as is possible.
As this amplier is tted with a powerful mains transformer, it is not recommended that sensitive audio equipment such as turntables or cassette decks be
placed immediately next to it. Do not place the SP100 in areas of direct sunlight, nor place it adjacent to a radiator or other heating appliances.
Like all ampliers the SP100 will generate a modest amount of heat. The cooling of this device is reliant upon the ow of air through the chassis grilles which
are located on the top and bottom of the cabinet. Care should be taken not to cover these grilles with items such as rugs, covers or curtains which will restrict
this air ow. Do not place the amplier on a soft surface as this may result in the bottom grille becoming restricted, and as a result may lead to over-heating.
Do not place records, tapes or compact discs on top of the unit. Be aware that after prolonged usage the chassis of this unit will become hot.
Never allow the amplier to come into contact with water or liquids, and ensure that small objects do not fall through the ventilation grilles. 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 trafc. 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 tted correctly, and that polarity has been maintained. This is especially important when connecting
loudspeakers to this amplier. 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 amplier 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 amplier, 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 amplier, 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 dene 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 ring loudspeakers onto a hard at surface can cause mid
range and high frequency colouration as reected 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- to suit your own listening tastes, and sit back and enjoy the
fruits of your labour.
