Connections
Installation
Locate the amplifier unit in the ceiling, wall or on the surface required. Tabs at each end of
the housing can be used for securing with screws.
Connect speakers using the supplied wires or equivalent by connecting “+” and “-” on the
speaker to the relevant connection on the amplifier unit. The speaker connections are via
screw terminals on a Euroblock, which can be removed for easy access whilst making
connections.
Important: Ensure that the load is no lower than 4Ωfor each output.
(e.g. 2 x 4Ω speakers… or… 2 pairs of 8Ω speakers wired in parallel)
Ensure that the speakers can handle 15W from each output.
Connect the line level stereo input signal to the Euroblock terminals labelled “AUX IN” as
shown on the Connections diagram above.
Left positive connection (Left+) should be connected to “L”
Right positive connection (Right+) should be connected to “R”
Both negative connections (Left- and Right-) should be connected to “G”
(G is the terminal for Ground connection –common for both Left and Right signals)
Likewise, the Aux input can be relayed to further amplifiers by connecting a line level output
from the Euroblock terminals labelled “AUX OUT”
AUX IN and AUX OUT connections should be made using shielded stereo audio cable and
not speaker cable.

Operation
When all connections are completed, make sure that the stereo input signal is turned down
and power up the amplifier by plugging in the supplied power adaptor to the 12Vdc input
from a 230Vac socket. Also power up any further amplifiers connected to the Aux output.
Gradually increase the input signal volume and check for output through the speakers.
Take care not to overdrive the input by turning the input signal up too high, which may
cause the sound to be distorted and subsequently cause damage to the speakers.
Power down the amplifier when not in use and isolate from the mains if not used for long
periods of time.
