ON / OFF
A sound system should be switched on sequentially. Switch on the self-powered units last in your sound
system (switch on the subwoofer before the mid-high 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.
Disconnect the device by removing the mains connector from the mains socket. The mains connector
and mains socket must always be freely accessible and never covered or blocked in any way.
The models use a power cable equipped with a Neutrik PowerCon TRUE1 connector. Power can be
daisy chained via the TRUE1 output connector (see details on product label).
IMPORTANT
: Do not disconnect the unit while in use.
Ensure that the device is disconnected from the mains by observing that the ON LED is turned off. Please
note that the ON LED can stay on for several seconds after the mains power has been disconnected.
Overload indicator
This device has a SIGNAL/LIMIT indicator. The
red light indicates the signal is excessive.
The indicator should not be lit continuously.
This distorts the signal (quickly fatiguing your ears)
and may damage the speakers.
Overheating
This equipment does not normally overheat
during normal conditions of use. When overheating
occurs, the unit protects itself. You should then
find out why and if necessary contact an
authorised dealer for technical assistance.
Normally it is enough just to let the unit cool
down after you have corrected the problem so that
the system functions properly again.
Equalisation
The unit does not need extreme settings of
equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above
+3 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.
The unit recognises the value of mains
automatically. The unit works from 80V to 260V
(both rms).
