Connections To The Mains
Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the
available supply is 240V~AC 50Hz. This product is CLASS1 and requires a protective mains earth
to be connected at all times. DO NOT remove or disconnect the earth.
Power On/Off Procedure
After connecting your amplifier to the mains, turn all controls counter clockwise to the “min”
position. Turn on audio sources (MP3 players, CD players, Microphones etc) before powering the
amplifier ON. The last product to be switched on is the amplifier.
If you wish to power off the system, turn the amplifier’s master volume control counter clockwise
to the “min” position before switching the amplifier OFF before any audio sources are switched off.
By following this procedure it will prevent acoustic shocks to the speakers or potential damage to
system components.
Machine operation
1. After connecting all audio source and powering on the power amplifier, adjust the and the
master volume.
2. The Clever Acoustics amplifier features output signal LED with PEAK indication. Should the
PEAK indicator illuminate (flashing) the output of the amplifier is too high, turn the master volume
anti-clockwise to reduce the output.
3. The Clever Acoustics amplifier all features protection with LED indication. Should the
PROTECT indicator illuminate, turn the master volume control anti-clockwise fully and switch off
the amplifier for 15 seconds as the amplifier may have entered PROTECT mode temporarily due
to a peak signal, care should then be taken to ensure all input levels are set correctly. If the
amplifier persists to enter PROTECT mode the amplifier should be switched off and left to cool
for 5-10 minutes before switching back on. If the PROTECT indicator remains lit this indicates a
problem with the amplifier or amplifier load (ie Short Circuit).
4. Speaker & Amplifier systems can produce high sound pressure levels, please operate all
controls with caution to ensure people are not exposed to excessive or dangerous sound pressure
levels.
