Mounting the amplifier
Siting the back box is simplified by fixing an adhesive template to the wall, ensuring that it is horizontal
ideally using a spirit level. Drill the fixing holes and place suitable wall plugs in the holes to suit the wall
surface ie masonry or plasterboard etc.
Ensure that the cable entry is facing the direction that you want before fixing to the wall.
If additional cable entries are to be used decide where the cable shall enter the box and use pliers to break out the
plastic knockouts. Pass the cable through the hole and align the box up to the fixing hole you have drilled. Use
countersunk screws to fix the box to the wall. Before they have been fully tightened, use the spirit level to check that the
box is level.
Mounting the amplifier in Dado Trunking
The dual gang faceplate fits standard UK dual gang Dado accessory mounts and backboxes, but be sure
that the Dado backbox depth is sufficient for the cables and connectors. The amplifier requires a minimum of
35mm and if used with the internal DC power module 45mm.
Speaker installation
The amplifier is suitable for use with 4Ω or 8Ω speakers
Before connecting speakers to the amplifier. make sure that the amplifier and all associated equipment is
turned off.
Use a loudspeaker cable no lighter that 14 gauge AWG and no longer than 30 ft (10 metres) to avoid
noticeable signal loss from the cable.
Connect the cable leads from the output of the amplifier to the input terminal (binding) posts on the rear of
the loudspeaker cabinets.
Make sure that the speaker wires connect the amplifier to the speakers correctly ie the Left + on the amplifier
to +(or Red) on the speaker installed on the left side and Left – on the amplifier to – (or Black) on the same
speaker to maintain line polarity and to avoid phase distortion and simarlary with the Right speaker
connections.
•
Do not place the loudspeakers in a location where they will be exposed to direct sunlight, high
temperature, or high humidity.
•
Turn the volume control of your amplifier to it's lowest volume when first turning it on to avoid
damaging the speakers.
•
Do not exceed the maximum power rating of the speakers, as sound quality will be impaired and the
loudspeaker drivers may be damaged.
Operating instructions
Check that the volume control on/off switch is in the off position before connecting the DC power supply to
the amplifier or mains power to the power supply.
Ensure that all connections have been made including the speakers before switching on.
To obtain the best output quality, please select the correct input type corresponding to the input source as
follow:
For MIC input, slide the switch to the ‘MIC’ position.
For MP3 input, slide the switch to the ‘MP3’ position.
For CD/VCD/DVD input, slide the switch to the ‘AUX’ position.
