The LOOP THRU  connector is an output XLR 

in parallel with the input connector and is useful for 
daisy  chaining  the  input  signal  to  a  number  of 
boxes, connecting them in parallel.

The number of units that can be linked this 

way  depends  on  the  output  impedance  of  the 
equipment driving the enclosure, such as the mixer 
or processor. Typically, to avoid signal degradation, 
the maximum number that can be daisy chained is 
given by the formula Zc>10Zs, where Zc is the 
load impedance and Zs is the output impedance 
of  the  equipment  driving  the  enclosure  (mixer, 
console, etc). For instance, a mixing console with 
100 ohm output impedance allows daisy chaining 
20  boxes,  when  the  input  impedance  of  the 
cabinets is 20 kohms.

The 

variant  25A

  unit  can  be  used  alone  for 

speech applications where low SPL is suitable. To 
use it in this mode simply plug the mixer into the 
input signal connector. To use it in combination 
with the 

variant 18A

 unit, plug the mixer into 

variant 

18A

 (INPUT) and connect the SATELLITE OUTPUT 

to the signal input on the 

variant 25A

 unit.

When  the 

variant  25A

  and 

variant  18A

  units 

cannot be on the same cluster it is recommended 
to  drive  each  model  separately  from  a  signal 
processor using a 138 Hz High Pass Filter for the 

variant  25A

,  adding  the  necessary  time  delay  if 

requeired and feeding the 

variant 18A

 with the full 

range signal.

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 units do not need extreme EQ. Avoid high 

levels of gain on the equalizers. Gain values above 
+6 dB on a console's EQ are not recommended.

The 

variant series

 amplifiers generate very little 

residual heat and therefore do not need a fan for 
cooling. In normal use, the amplifier panel will be 
warm to the touch.

If the unit stops playing (or just the mid-high or 

the  bass  sections),  the  amplifier's  overheating 
protection  may  be  activated  to  protect  the 
components from thermal damage. 

Overheating may be due to insufficient cooling, 

or  to  very  aggressive  use  in  extremely  hot 
conditions. Do not use the unit in proximity to high 
power lights.

Once  the  amplifier  cools  down,  it  switches 

back on automatically. If the unit should shut down 
again, try reducing the volume a notch to avoid 
overheating.

It  is  recommended  that  the  red  LIMIT  LED 

indicators are not lit continuously; at most it should 
blink only occasionally.

If you wish to have a visual indication at the 

mix  position  of  whether  the  LIMIT  LEDs  are 
lighting, during equipment set-up, closely observe 
what mixer VUmeter level corresponds to the level 
that lights the enclosure's LIMIT LEDs. That level 
that should not be exceeded during the event.

A  sound  system  should  be  switched  on 

sequentially. Switch on the self-powered unit last in 
your sound 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.

Mute all signal sources before switching the 

unit on or off.
