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.
Overheating
This equipment does not normally overheat
during normal conditions of use due to the use of
a high efficiency amplifier combined with a
heatsink. When overheating occurs, the unit
protects itself (at 80ºC at the internal amplifier´s
sensing point). This temperature limit can be
monitored with DASnet. In case of entering in
protection mode, you should then find out why and
if necessary contact an authorised dealer for
technical assistance.
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.
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.
Normally it is enough just to let the unit cool
down after you have corrected the problem so that
the system functions properly again.
The amplifier is provided with a radiator made
of aluminum which improves heat evacuation.
Keep grilles clean and dust-free.
Do not block or obstruct in any way the air
entrance or exit while the equipment is in use.
Air circulates from the bottom to the top of the
amplifier.
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 recognised automatically if it´s going to
work in 230Vac or 115Vac range
The nominal operating ranges are 85V to 125V
for 115Vac, or 170V to 250V for 230Vac..
Therefore the current consumed by a 115V
version is double the 230V version to achieve the
same acoustic power level.
For 230Vac the consumption of the unit giving
1/3 of power (with pink noise input signal) is 1.8A.
