Step Action
1 Connect the:
Left amplifier terminals to the respective Left speaker terminals;
and
Right amplifier terminals to the respective Right speaker
terminals.
Make sure when doing this that you maintain the correct + to + and –
to – connections.
2 Ensure that all connections points are clean, and that all connections
are secure. Check that wiring terminations look neat and that no
loose strands of wires are touching any other terminals. Failure to
make neat connections may result in poor sound, or amplifier
damage.

Whenever power is first applied to this remote-controlled
amplifier
When switched on at the power point, a beep will be heard after 2
seconds, once the MEPS (Minimum Energy Performance
Standards) power supply has stabilised. This is followed by a
rising 'whoop' sound; a number of beeps indicating its Firmware
version; if set higher than ½ way, Left then Right volume controls
are 'run down' till both set at ¼; a quick series of clicks from the
Power-On Self-Test of all relays and indicating lights; concluded
by a rising “ta-dah” tone, indicating that all is well. (See
“Firmware” page at end of manual for complete listing.)
