Overheating
This equipment does not normally overheat
during normal conditions of use. When overheating
occurs, the unit protects itself and the yellow LED
'Protection' lights up. 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.
Preliminary
This product should only be used in E1, E2, E3
or E4(*) environments, in accordance with standard
EN55103-2 (Electromagnetic compatibility. Product
family standard for audio, video, audio-visual and
entertainment
lighting control apparatus for
professional use. Part 2: Immunity.)
Do not cover the amplifier's radiator nor
obstruct its ventilation (except for the rain protector
supplied by DAS).
For consumption reasons, it is important not to
connect the equipment to the same line as the
lighting systems, thus avoiding interruptions or
sudden drops in lighting intensity.
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 sund
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 mains cable can be detached from the
device by disconnecting the Neutrik PowerCon
connector. Pull the metal lock back, turn the
Neutrik PowerCon counter clockwise to stop and
pull the Neutrik PowerCon connector out. Always
disconnect the device by removing the mains
connector from the mains socket before detaching
the
mains cable at the Neutrik PowerCon
connector.
IMPORTANT: Do not disconnect the Neutrik
PowerCon connector during music.
Ensure that the device is disconnected from
mains by observing that the lamp marked POWER
is turned off. Please note that the POWER lamp
can stay on for several seconds after the mains
power has been disconnected.
Overload indicators
The indicators should not be lit continuously.
This distorts the signal (quickly fatiguing your ears)
and may damage the speakers. Therefore, it is
recommended that you never work with this leds
on; at most they should blink only occasionally.
This device has two indicators (red leds), one
for overload input signal and other for the
amplifier’s clip.
Equalisation
The units 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.
(*)Note
E1.- Residential.
E2.- Commercial and light industrial.
E3.- Urban outdoors.
E4.- Controlled EMC environment and the rural
outdoors environment.
Low mains voltage
If mains voltage falls below the shutdown
voltage for the unit, it will stop playing (the yellow
led is on: Protection activated). When acceptable
levels are regained, the unit will switch back on
automatically
.
In the case of the , the maximum
voltage is 264 Vrms and the shutdown voltage is
156 Vrms (divide by 2 for 115V).
and , the
mains supply input can assess the network's
voltage level and thus makes the system work in
two possible voltage ranges: From 85 Vrms to 130
Vrms; and from 170 Vrms to 260 Vrms.
Therefore, in a country with a nominal mains
supply voltage of 120 Vrms, the unit will
disconnect when the voltage in the socket goes
below 85V or above 130V (both Vrms). Likewise, in
a country with a nominal mains supply voltage of
230 Vrms, the unit will disconnect itself when the
voltage at the plug goes below 170V or above
260V (both Vrms).
The current draw for 230 V can be seen on the
accompanying table. Double the ratings to get the
115V current consumption.

deactivated)
