Operation
1.
Connect loudspeaker system (MINIMUM load 4 ohms) with sufficient handling capacity to the output terminals
of the amplifier. Connect output from television, dvd player, computer, mixer or any other suitable signal source
to the appropriate input sockets of the power amplifier. On the front panel you can connect your MP3 player
with a 3.5mm stereo jack connection lead.
2.
Connect the power cord to the mains.
3.
Select the correct source with the selector on the front. (PC – MP3 – TV – CD)
4.
Turn gain controls to minimum and then switch on the amplifier.
5.
Adjust the volume controls to required level. NOTE. If the audio input signal is too high, distortion will result
and the CLIP indicator will light. If the clip LED is lit permanently or flashes, the level should be reduced
6.
Use the equalisers (not SPL400) to make adjustments to the sound. They can compensate for sound quality
differences in the source material, or differences in room acoustics. Each EQ has his own boost or cut for low,
mid & high frequencies
.
For reliable and trouble free operation, please observe the following points:
•
Ensure all input / output connections are correct and secure.
•
The handling capacity of the loudspeakers is adequate for the output of the amplifier.
•
Always site the amplifier in a well ventilated location
•
Protect unit from severe shocks
•
Do not plug in or unplug the speakers during the operation of the amplifier. This could seriously damage the
amplifier.
