Acoustic Solutions SP 101 - Manual (Page 5)

INSTALLATION AND POSITION
This amplifier should be positioned on a flat stable surface. We would
recommend that the position of your hi-fi equipment should be chosen carefully
to provide adequate protection for this device, but also provide an attractive
showcase for your investment. Hi-fi equipment is not designed to be moved
often, therefore it is recommended that a permanent home for your hi-fi be
achieved as soon as is possible.
As this amplifier is fitted 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 SP101 in areas of
direct sunlight, nor place it adjacent to a radiator or other heating appliances.
Like all amplifiers the SP101 will generate a modest amount of heat. The
cooling of this device is reliant upon the flow 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 flow. Do not place the amplifier 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 amplifier 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 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.
