D.A.S. Action 18a User Manual

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 mains cable can be detached from the
device by disconnecting the standard IEC-60320
connector (only action 18A). Always disconnect the
device by removing the mains connector from the
mains socket before detaching the mains cable at
the standard IEC-60320 connector (only action
18A).
The rest of models use a power cable
equipped with a Neutrik PowerCon NC3FCA
connector. Power can be daisy chained via the
NC3FCB 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.
Low mains voltage
Therefore the current consumed by a 115V
version is double the 230V version to achieve the
same acoustic power level.
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.
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 action 218A amplifier is equipped with fan
and heatsink to maintain the correct operating
temperature.
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.
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.
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 an indicator (LIMIT LED) that
lights when the signal is excessive.
The indicator 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 LED
on; at most it should blink only occasionally.
