Operating Your Amplifier: Initial Set-up and Switching On

Please read all documentation before operating your amplifier and retain all documentation
for future reference.
Do not spill water or other liquids into or on the unit and do not operate your amplifier while
standing in liquid.
Do not block fan intake or rear ventilation outlets or operate the unit in an environment that
could impede the free flow of air around the unit.
If your amplifier is used in an extremely dusty or smoky environment, it should be cleaned of
any collected debris at regular intervals. Please also see the notes regarding maintenance on
page 18.
It is important that the power output of your amplifier is matched to the power handling
capacity of your loudspeaker. If not, damage to the loudspeaker could occur.

Switching On...

At 'switch-on' the protection circuit will initially activate whilst the circuits stabilise, indicated
by the red Protection LED illuminating, in addition to various other LEDs. After a few seconds
the red Protection LED will extinguish indicating a satisfactory working condition.
Other LEDs may remain illuminated depending upon rear panel switch settings and input
connections. If the Protection LED does not extinguish after 5 seconds the unit may be faulty
or some external connections may be incorrect or inappropriate. If this occurs, you should
power down the unit and remove all external connections (except for the mains power supply)
and repeat the power up sequence. If the problem persists please contact us — details on
page 19.
