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.
