  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.
