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.
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.
USING THE FUNCTION MENU This SP100 amplifier is fitted with a digital user interface which allows complete control of the features of this amplifier. The menu structure of this product is as follows: Volume control default setting 1. The default setting for the user interface control is the ‘volume’ setting. This will be displayed on line one of the LCD display as a numeric dB value. 2. 3.
BASS CONTROL This amplifier is fitted with a bass control which offers +/-14dB attenuation around the centre bass frequency of 100Hz, and +/-3dB across the frequency range of 45Hz to 259Hz. To alter this bass control press the function button once, this will change the LCD display for bass control. The last setting for the bass will be displayed. To change the bass setting turn the rotary control (10) either clockwise or anticlockwise to increase or decrease the bass content.
TREBLE CONTROL This amplifier is fitted with a treble control which offers +/-14dB attenuation around the centre frequency of 10Khz, and 6dB across the frequency range of 2Khz to 20Khz. To alter this treble control press the function button (9) twice to change the LCD display from bass control to treble control. The last setting for the treble will be displayed. To change the treble setting turn the rotary control (10) either clockwise or anticlockwise to increase or decrease the treble content.
BALANCE CONTROL This amplifier is fitted with a balance control which allows the volume of the left and right signals of the stereo image to be altered in order to compensate for an off-centre listening position. To activate the balance control press the function key (9) three times to change the LCD display to the balance control. The last setting for the balance will be displayed.
LOUDNESS CONTROL This amplifier is fitted with a loudness control which provides a boost to lower frequencies at lower listening volumes. This creates the effect of increasing the perceived amount of bass / mid content in the music when playing the amplifier at a lower level. This control is effective on frequencies between 20Hz and 800Hz and its effect decreases as the amplifier volume level is increased. When the amplifier volume reaches its maximum, the effect this loudness control has is negligible.
SPEAKERS ON/OFF CONTROL This amplifier is fitted with a loudspeaker control which allows the loudspeakers to be turned off when listening through headphones To activate the speaker control press the function key again five times to change the LCD display to the speaker control. The last setting for the loudspeakers will be displayed. To change this speaker setting turn the rotary control (10) either clockwise or anticlockwise to change the setting from on to off or vice versa.
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. If this unit is used in a dusty environment, it may be necessary to have the unit serviced at your local dealer periodically.
TROUBLE SHOOTING 2 Symptom Loud buzz or hum Will not play or make tape recordings 15 Possible cause • Audio input cables damaged or not correctly connected. • Turntable earth lead incorrectly fitted. • Turntable head shell incorrectly fitted. • Tape machine sited too close to amplifier, or TV. • Tape input / output connections reversed. Weak bass, diffused stereo image • Speaker connections out of phase, check + and – terminals are connected to corresponding terminals on both amp and loudspeakers.
