You might not expect it, but that is exactly what Acoustic Solutions SP delivers and more besides. Four presets are probably enough for most with DAB as the tuning interface is simplicity itself to swap between channels. With such a finely crafted exterior you might expect the inside to look like a spaghetti of wires with a bolognaise of cheap components thrown in - but not so. You get a decent Radioscape DAB chipset and a meaty power supply, and the layout it neat and efficient. It is superbly clear and can display scrolling text information and data about the broadcast at the same time. Oh how wrong.

If this should happen, refer to qualified service personnel before attempting to use. For your safety please observe the following information. Will give an indication of volume position and input source selected. Will also display other menu features as described on pages This can be used with optional 3 in 1 remote control which is available. Stereo 6. Light will show green to indicate that the SP is on. It will show red if the SP is in stand by mode set by the optional remote control.
Please be aware that this unit contains high voltages, and should not be opened, please refer to page 2 of this manual. Please ensure that this cable strain relief bush is intact and has not been damaged. Ensure wires are not frayed or touching.
This is for connection to external amplification or recording equipment. For the connection of a turntable. It is necessary to provide a chassis earth connection between the turntable and the amplifier. Failure to do this will result in a buzzing or humming noise from the loudspeakers. 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 SP in areas of direct sunlight, nor place it adjacent to a radiator or other heating appliances. Like all amplifiers the SP 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. 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. These can be altered according to your listening tastes; these new settings will be retained within the memory of the amplifi er and will remain set even after switchiing off this system.
To change which input source is listened to, press once the switch below the corresponding piece of equipment which is required. Pressing another input source switch will change which music source is listened to. The LCD display will show the corresponding input source selected on line 2 of the display, this will change according to which input selector switch is pressed.

Acoustic Solutions SP150 User Manual
In this multi-page review, we look at some of its strengths and weaknesses including the electronic design. From the block diagram, we can see that this IC has built-in standby and mute functions. It also has built-in short circuit protection and automatic thermal shutdown, thereby making it a very hardy power output stage. This part of the amplifier design is superb and consequently I figure there will be many amplifiers that will survive in the hands of us Brits.
