Switch ON/OFF
A sound system should be switched on
sequentially. Switch on the self-powered unit last in
your sound system. Switch on the sound sources
such as CD players or turntables, then the mixer,
then the processors, and finally the self-powered
unit. If you have several units, it is recommended
that you switch them on sequentially one at a time.
Follow the inverse order when switching off,
turning self-powered units off before any other
element in the sound system.
Mute all signal sources before switching the
unit on or off.
Overload ( indicators limit)
It is recommended that the red LIMIT LED
indicators are not lit continuously; at most it should
blink only occasionally.
If you wish to have a visual indication at the
mix position of whether the LIMIT LEDs are
lighting, during equipment set-up, closely observe
what mixer VUmeter level corresponds to the level
that lights the enclosure's LIMIT LEDs. That level
that should not be exceeded during the event.
Overheating
Due to their high efficiency, the
amplifiers generate very little residual heat and
therefore do not need a fan for cooling. In normal
use, the amplifier panel will be warm to the touch.
If the unit stops playing (or just the mid-high or
the bass sections), the amplifier's overheating
protection
may be activated to protect the
components from thermal damage.
Overheating may be due to insufficient cooling,
or to very aggressive use in extremely hot
conditions. Do not use the unit in proximity to high
power lights.
Once the amplifier cools down, it switches
back on automatically. If the unit should shut down
again, try reducing the volume a notch to avoid
overheating.

Equalisation
The units do not need extreme settings of
equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above
+6 dB on a console's EQ are not recommended.
Low mains voltage
If mains voltage falls below the shutdown
voltage for the unit, it will stop playing. When
acceptable levels are regained, the unit will switch
back on automatically.
Connections
The can be used full-range or
reinforced with .
Full-range use is only recommended for
applications where not a lot of SPL is required. To
use it in this mode simply plug the mixer into the
enclosure's input.
To use it in combination with the , plug
the mixer into the input, and connect the
SATELLITE output to the s input. If you
have more boxes, simply daisy chain s and
s as shown.
