This combination of
Class D and Class H
amplifier technologies
helps keep distortion
to a minimum while
reducing the need
for massive heat dis-
sipation. In fact, to a
level low enough to
eliminate the need
for heavy heatsinks.
The advantage of
this unique combina-
tion of two-tier and
Class D amplification
has reduced extrane-
ous heat to the point
that NX55P’s can easily be
used in any orientation (close to walls,
floors and in close arrays with multiple
cabinets). Competitive active loudspeak-
ers, with large finned heatsinks, need to be
operated vertically and with plenty of clear-
ance (to ensure proper heat dissipation and
ventilation). Since you have more versatility
in regards to the orientation of the enclosure,
the NX55P becomes ideal for flying in large
clusters and in point-source concert sound
systems. Yorkville’s designers took extra care
making sure that in tight clusters overheating
would not be an issue.
Taking advantage of the design process, an
opportunity was taken to tweak the electronics
for maximum overall speaker performance and
protection. Solutions were borrowed from our
high-end TX-Series PA systems. The limiters used,
at the input and crossover stages, are a complex
combination of gain reduction and sweep-
ing filters. If the NX55P is pushed to its maximum
input/output levels, advanced filtering begins
rolling off unnecessary subsonic frequencies. The
processing also protects individual components
ensuring failure free operation (even after long
term operation at close to maximum output
levels). The filter has a remarkable response time,
less then 70ms, allowing the system to constantly
be re-tuning itself. This makes 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
the mix, like the vocals
or solo instruments,
come out clean and
clear when the cabinet
is being operated at the
extremes of power and
woofer excursion. Ex-
tremely fast and accurate
limiting is in place to protect
the speaker components.
As a bonus, the NX55P
has a built in mixer! This al-
lows the loudspeaker to be
used directly with a micro-
phone and/or line source. The
loop output allows additional active
cabinets to be driven from one source (up
to a maximum of 50 NX55Ps). If desired, you
can combine a pair of the NX55P’s using the
mixer inputs on each cabinet and coupling
the loop outputs. In this example you would
have an ideal presentation system. Two
microphone inputs, two line inputs (opti-
mized for CD, Cassette or laptop computer
audio source), complete within two speaker
cabinets. As mentioned, our active cabinets
can be linked together, the limitation is that
only three ‘mixers’ can be active at any one
time. This allows three Mic sources and six
line sources available in an array of three or
more cabinets). The microphone inputs have
equalization and high pass filtering designed
appropriately for vocal applications. The trim
control allows looped cabinets to be individ-
ually adjusted in level. This is invaluable in ap-
plications where large numbers of cabinets
are used such as in clusters or in trade show
applications (or when NX55P’s are used as
repeater cabinets or for side fill). The 100 Hz
high pass filters allow the NX55P to be used
more efficiently with any active subwoofer.
Using the popular nx20 as a base, adding 550 Watts of bi-amped power and topping-it-off with aad-
vanced signal processing, the NX55P is destined to set the new standard for active loudspeakers. The
woofer amplifier, or low frequency amplifier, amp delivers over 450 Watts to the 12 inch neodymium
woofer. To reduce the overall weight of the amplifier section, the woofer amplifier uses Class D
switching technology. A 100 Watt, two-tier linear technology, Class H amplifier drives the 1 inch dia-
phragm horn driver. This allows the horn to produce clean transients while keeping up with the high
output of the woofer. Two-tier amplifier technology isn’t typically seen in a product like this, however
we found the advantages (lower weight, more efficiency, higher headroom and lower operating
temperature) made it a perfect choice for powering the top end.

The NX55P is a bi-amped powered full-range
loudspeaker with a built-in two channel mixer.
Multiple NX55P cabinets may be connected
through the Link option. If you’re using the
NX55P with an external mixer, the internal mixer
can be disabled. The built-in mixer has a micro-
phone input and two (combined) ¼ inch inputs
for line sources such as CD players. Advanced
signal processing is used to give maximum
performance at all levels. There’s a switch to
provide a low frequency rolloff if you’re going
to use the NX55P with a subwoofer.
Any regular microphone can be inserted into
the Mic input. Phantom power is built–in for
condenser microphones.
The Line/CD inputs allow line-level sources such
as CD players, cassette decks or any other
sources such as mixers to be connected. If
more than one input is used these inputs blend
the signals (e.g. stereo sources) into mono. The
inputs are balanced to help reject hum (when
used with balanced cables) Unbalanced
1/4-inch plugs can be used. When connect-
ing to unbalanced sources using balanced
T.R.S. cables does help reduce unwanted noise
and/or hum. These inputs can be used for
lower-level Line inputs, which need a bit more
gain (as opposed to using the Link jacks, which
have no control). These inputs allow you to
have a greater range of level adjustment than
using just the NX55P Level control (e.g. if an in-
dividual cabinet, in the chain needs to operate
at lower level than the rest).
These parallel jacks allow multiple NX55P cabi-
nets to be connected together. The Link Jacks
are the correct input to use when driving the
NX55P from an external mixer. The Link Jacks op-
erate at line level (+4 dBv) to achieve full power.
The NX55P Level control allows operation at
levels from –2 dBv to +10 dBv for full power. When
operating from signals that are not as strong, use
the Line inputs of therst cabinet in the chain.
The Link jacks are high quality balanced inputs
with very good common mode (hum) rejection.
To ensure maximum hum rejection, the proper
balanced cables must be used. When con-
necting to unbalanced sources using balanced
T.R.S. cables does help reduce unwanted noise
and/or hum. Jacks marked LINK OUTPUT are con-
nected in parallel with the LINK INPUTS and are
provided for convenience to connect down-
stream cabinets. Link inputs may also be used as
outputs and link outputs may be used as inputs.
This control allows the audio level of the
cabinets, linked in a chain, to be individually
adjusted. This control does not adjust the level
of the Link jacks. The Level control should be
set at '0' (center) for most applications.
For operation with a subwoofer, the LF Rolloff
switch shuts off the low frequency boost and
filters out signals below 100 Hz. It’s not neces-
sary to use this switch for speech applications
because the Mic input already has a high pass
filter. This switch only affects the signals to the
internal amplifier and does not affect signals
going out from the internal mixer, or to signals
passing through the Link connections.
The Mixer On/Off switch turns the NX55P’s
internal mixer on the rear panel on and off.
The NX55P’s mixer should be used when a
microphone or CD player is directly connected
to one of the NX55Ps Line/CD or Mic inputs. It
should be switched off* if the NX55P’s Link Input
is connected to a separate mixer’s output.
*Note: the NX55P has been designed to enable the
user to interconnect multiple NX55Ps (up to 12 or
even more) via the Link Inputs and Outputs. When
linking NX55P's, a maximum of 3 of the NX55P’s
internal mixers can be used (activated) allowing up
to 3 microphones and 3 line sources to be mixed
without an external mixer. This is useful for smaller
music engagements, meetings, seminars, etc.
This control adjusts the volume level the
Mic input. The microphone signal output to
other cabinets through the link connections
will be affected as well.
