AMPLIFIER (cont'd)
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-S18A). 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-S18A).
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.
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.
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.
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.
ACTION-S118A and ACTION-S218A amplifiers are 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.
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.
Therefore the current consumed by a 115V version is double the 230V version to
achieve the same acoustic power level.
