The new NX55P active speaker enclosure
uses a combination of amplifier technologies to create the best
combination of lightweight enclosure and high quality sound.
Capitalizing on the already popular NX35’s molded cabinet technology, totally new switching power supply amplification and neodymium drivers, the 550 watt bi-amped NX55P weighs in at only 47 lbs (21.4kg) ... the lightest in its class by a long shot.

Like all NX series enclosures,the NX55P is manufactured
using tough, light weight low resonance variable density composite
materials. In addition they are UV and moisture resistant. The NX55P
enclosure itself has been molded for maximum versatility. The trapezoid
box is ideal for mounting in arrays, or for use as a monitor. An
improved wedge monitor angle has been incorporated into the new design.

The horn amplifier uses a two-tier class H linear technology,
allowing the horn to produce loud clean transients to keep up with the
high output of the woofer. The two-tier amplifier technology is a lower
weight, more efficient amplifier with higher headroom and lower
operating temperature. It is a perfect solution for powering the top
end.

A newly designed switching amplifier drives the bottom end or woofer in the NX55P.
The woofer or low frequency amplifier uses Class D switching technology
to reduce overall weight of the amplifier section. This technology is
similar to the power supply found in the new Yorkville A4.4 power amplifier, the EF500P active enclosure and new MicroMix M8 powered mixer.

The NX55P 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.

In the case of the NX55P, the combination of neodymium
woofer magnetics, lightweight composite materials and high tech
amplifier technology create a loudspeaker that has remarkable
performance in such a lightweight package.

The NX55P has a versatile direct input system and
built-in mixer. The mixer allows the loudspeaker to be used directly
with a microphone and / or line source. The loop output allows
additional active cabinets to be driven from one cabinet’s mixer stage,
or a series of cabinets to be driven from one source. If desired, the
end user can combine multiple NX55P’s using the mixer inputs on
each cabinet and coupling the loop outputs. In this simple example you
would have the ideal presentation system with two microphone inputs,
two line inputs.

The microphone input has equalization and high pass filtering
appropriate for vocal applications. The trim control allows looped
cabinets to be individually adjusted in level. The NX55P
has user defeatable 100Hz high pass filters allow either cabinet to be
used more efficiently with any Yorkville active subwoofer.

The NX55P enclosure itself has been molded 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.

We''ve also found an opportunity to tweak the electronics for
maximum overall speaker performance and protection. Borrowing some
ideas from our powerful and popular TX Series PA systems, the limiters
used in the input and crossover stages are a complex combination of
gain reduction and sweeping filters. As the NX55P
is being pushed to its maximum input / output levels, it''s advanced
filtering begins rolling off unnecessary subsonic frequencies.

The filter has remarkable response times (less than 70ms), allowing the
system to constantly be returning itself to make sure the output is as
clean, as loud and as clear as possible at any given moment. This is
achieved without negatively affecting the overall sonic quality of the
cabinet. This ensures that the essential part of any mix, like the
vocals or solo instruments, comes out clean and clear at the extremes
of power and woofer excursion. Extremely fast and accurate limiting is
in place to protect the speaker components.

The NX55P has a built in mixer that allows the
loudspeaker to be used directly with a tuned microphone and / or line
sources such as mixer, CD player or laptop computer. The loop output
allows additional powered cabinets to be driven from one cabinet''s
mixer stage, or a series of cabinets to be driven from one source. If
desired, the end user can combine a pair of the NX55P's using
the mixer inputs on each cabinet and coupling the loop outputs. In this
simple example you would have the ideal presentation system with two
microphone inputs, two line inputs optimized for CD, cassette or laptop
computer audio source, complete within two speaker cabinets. Many NX55P's
can be linked together but a maximum of three "mixers" can be active at
any one time. (Making three mic sources and six line sources available
in any three or more cabinet array). The microphone input has
equalization and high pass filtering appropriate for vocal
applications. The trim control allows looped cabinets to be
individually adjusted in level. This is valuable in applications where
large numbers of cabinets are used such as clusters or in trade show
applications. The NX55P has a selectable two position high-pass
filter to limit extraneous low frequency rumble, or to crossover at the
input so the loudspeaker can easily and effectively be used with
subwoofers from a single full range source. Engaging the high pass
filter also makes the NX55P a more efficient and effective vocal monitor.

The NX55P is an ideal loudspeaker for mobile
presentation PA where high volume and superior sound quality is
required. Multiple loudspeakers can easily be linked using mixer inputs
from each loudspeaker to create a six input system... no external mixer
required. (Up to three "mixer" sources can be used in any one system.)
