SYSTEM POWER SEQUENCING
To prevent unwanted sounds from being produced by the system, always observe the correct power on/off
sequence. Always follow the rule of thumb…
“Amplifiers are the last on and the first off”
Always ensure that the powered speaker system is the last thing you power up, and the first thing you turn off
when operating a complete PA. Bring the output level of the mixer to zero while you turn on any sources such as
CD players, turntables, mixers, instruments and any outboard processing. Then turn on subwoofers, then the top
boxes. You are now ready to bring up the level control on the mixer. If speakers are daisy chained together, turn
off the last speaker in the chain first.
OPERATING TEMPERATURE
The design of the amplifier is such that it is very efficient and as a result, shouldn’t get too hot. In the rare event
that it does get too hot, it will shut down to protect itself. The temp led will light to let you know. A condition
where this might occur is when it is operated in very high ambient temperature or when the heat sink on the back
of the cabinet is in direct sunlight. Always ensure adequate cooling and appropriate shade. When its temperature
has returned to within its operating temperature range, it will turn back on.

OPERATION
AC POWER
The Klarity family of loudspeakers use Neutrik’s
PowerCON connectors for AC power connection. The
powerCON is a locking AC equipment connector with
contacts for line, neutral, and a pre-mating ground
contact. It replaces the standard IEC AC power
connector with a very rugged solution in combination
with a locking device to guarantee a safe and reliable
power connection. The locking tab prevents the AC
power from accidently becoming disconnected. The
grey colored receptacle can be used as a power out
connection to daisy chain to another Klarity series
cabinet. To connect, match the keyways with the
receptacle, push it all the way in and twist until you
hear the locking “click,” letting you know that the
connecter is mated to the receptacle. Similarly, to
disconnect, pull the locking tab towards you, twist and
pull until the connecter is out of its receptacle.
Before plugging in the Klarity speaker systems into an
outlet, verify that it is able to provide the appropriate
voltage and current as required by the speaker.
A robust AC supply is necessary for maximum
performance; if it is too weak, the bass performance
may be affected and if it sags too much (brown-out),
the system may self-mute to protect itself. As soon as
the appropriate AC supply is restored, it will continue
to operate. Plugging multiple systems into the same
outlet and using long extension cable runs can affect
the AC supply to the system.
