NX300P - Active Speaker - 600w, 15-inch / 1-inch
The NX300P offers a great value for a 15-inch and horn active loudspeaker enclosure. The
enclosure uses the same proven design as the NX55P active enclosure. The biamped 600-watt
(peak) power module has a minimum of controls yet provides maximum versatility making the
NX300P the ideal solution for many applications.
A 2-band EQ, XLR balanced microphone input and a balanced Combi-jack (XLR / TRS 1/4-
inch TRS) line input on the power module means the NX300P can be easily connected to any
source, and setup quickly with a balanced EQ for the room. An XLR balanced line output allows
multiple NX300P ’s to be linked together for use in a horizontal array or for easy distribution
around a large room when used as repeater cabinets.
The horn/tweeter amplifier uses class A/B technology, allowing the horn to produce clean
transients to keep up with the high output of the woofer. The woofer (low frequency) amplifier
uses class-H 2-tier amplifier technology. This achieves a lighter weight and more efficient audio
amplifier with higher headroom and lower operating temperature. Each amplifier has it own
limiter to prevent distortion caused by clipping.
The NX300P enclosures, like all enclosures in the NX loudspeaker line, have been designed
for maximum versatility. The trapezoid box is ideal for mounting in arrays, or for use as a monitor
cabinet (with well-protected inputs and controls). The NX300P can easily be used in any
orientation, and close to walls, floors and in close arrays with multiple cabinets. Particular care
was taken designing the components to reduce extraneous heat production.

Power Switch and LED
The Power Switch turns the
power on and off for the
NX300P enclosure and the
green LED will illuminate when
the power is on also indicating
a properly functioning fuse.
Mic In
The balanced XLR
microphone input can be
used with any dynamic or
condenser microphone.
Line In
The balanced Combi-jack (XLR/1/4-inch TRS)
input can be used with any line source such
as a CD player or an electronic instrument
with a line output. It‘s always recommended
to use balanced sources when possible,
this helps prevent the risk of hum or buzz
associated with unbalanced connections
(especially if the cable is long or the
source is operated from a separate
AC power connection). Since the
Mic In and the Line In each have
their own input and level controls,
they can be used at the same time.
Mix Out
To allow operation of multiple
NX300P enclosures from a single
source, the Mix Out line output is
provided. It should be connected
to the Line In of the next NX300P
in the chain. The Line In level
control on the subsequent unit in
the chain should be set to 0 dB in order to
provide the same output level as the master
enclosure. When connecting multiple NX300P
enclosures, the last NX300P in the chain
should be powered off first (and powered on
last). Each NX300P should be powered on or
off before the previous NX300P in the chain.
This will eliminate unwanted on/off noises.
