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.

• Ultra-clear reproduction throughout

the whole bandwidth

• High efficiency, high tech, 550 Watt Bi-

amped power module

• Superior TX-style processing and

component protection

• True 1 inch diaphragm horn driver

• Low distortion/high power-handling

12-inch woofer

• – dB / + 6 dB Level control (for individual ∞

cabinet level adjustment)

• XLR and TRS inputs / outputs for easy

connection and looping

• Multi-input source mixer for direct inputs

• Direct microphone input with level control

• Two way overall EQ controls

• Integrated flying hardware (3/8 inch

threaded holes)

• Tough, full-length metal grille

• Recessed Mixer panel

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 the rst 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.
