INTRODUCTION 

 

 

AMPLIFIER DESCRIPTION 

 

3

Features

This powered subwoofer system is designed to 

reproduce  the  low  frequencies  of  the  audio 
spectrum, providing a high level of power.

It comprises two 18” model 

18LX

 long-excursion 

loudspeakers 

with 

enhanced 

performance 

(increased power handling capabily and reduced 
distortion) and optimized design.

The amplifier features an intelligent power supply 

which detects the mains voltage level and adjusts 
internal  voltages  to  ensure  maximum  system 
efficiency.

Furthermore, the 2400W class D amplifier offers 

exceptional  performance  and  minimum  heat 
generation.

The  digital  signal  processing  (DSP)  provides 

improved control over the input signal treatment.

The  "R"  version  features  rigging  hardware 

enabling the systems to be flown simply, safely 
and efficiently.

A) INPUT CLIP:
Red LED indicates and excessive input signal, 

saturation of the DSP and excessive increases in 
distortion.

B) LOOP THRU :
XLR-type 

output 

signal 

connector 

for 

connecting  several  units  together  and  sending 
them all the same signal.

C) INPUT :
XLR-type input signal connector, which just like 

the  LOOP  THRU  connector,  is  a  balanced 
connector with the following pins:

1=GND (Ground).
2=(+) Non invertided input.
3=(-) Invertided input.
D) CLIP :
Red LED indicates amplifier saturation, in other 

words, when it reaches Clip.

E) PROTECTION :
Yellow  LED  indicates  that  the  protection 

system has been activated. If the problem that 
activated the protection is resolved, the amplifier 
will  restart.  The  problems  that  can  activate  the 
protection system are:

-Mains power out of operating range
-Overheating.
-Overload or short-circuit.
-DC voltage present at the loudspeaker output.
F) SIGNAL :
Green LED indicates signal.
G) POWER :
Green LED indicates ON.
H) Heatsink.
Although  the  heatsink  does  not  reach  high 

temperatures  (during  normal  use),  the  heatsink 
should not be covered or obstructed in any way 
and it should not be touched.

I) AC INPUT :
Neutrik model PowerCon 'NCA3' connector for 

connection  to  the  mains  supply.  This  only 
connects  when  it  is  turned  and  locked  and  is 
equipped with a securing tab.
