NX55P Active Full Range Loudspeaker

Using the popular nx20 as a base, adding 550 Watts of bi-amped power and topping-it-off with aad- vanced signal processing, the NX56P 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. À 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.

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 fying 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 ftweak the electronics for maximum overall speaker performance and protection. Solutions were borowed from our high-end TX-Series PA systems. The limiters used, af the input and crossover stages, are a complex combination of gain reduction and sweep- ing filters. If the NX56P is pushed to its maximun input/output levels, advanced filtering begins rolling off unnecessary subsonic frequencies. The processing also protects individual components ensurng 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 constantiy 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 hat the essential part of he 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 +o a maximum of 50 NX55P5). 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.

The NX56P is a bi-amped powered ful-range loudspeaker with a built-in two channel mixer. Multiple NX55P cabinets may be connected #hrough the Link option. If you're using the NX56P with an external mixer, the internal mixer can be disabled. The built-in mixer has a micro- phone input and two (combined) 4 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 TRS. 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- nes to be connected together. The Link Jacks are the correct input to use when driving the NX56P 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 fhe first 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 TRS. 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 fiers out signals below 100 Hz. If'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. # should be switched off“ if the NX55P's Link Input is connected to a separate mixer's output.

“Note: the NXSSP has been designed to enable the user lo interconnect multiple NX58PS (up to 12 or even more) via the Link Inputs and Outputs. When linking NXSEP'S, a maximum of 3 of the NXS5P'Ss interal mixers can be used (activated) allowing up 10 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.

This control adjusts the volume level of devices plugged into the Line/CD input. The signal out to other cabinets, from this device, through the link connections will be affected as well. A line-level signal and microphones can be con- nected simulataneously.

10. Treble and Bass Controls These controls affect the signals from devic- es plugged into the Line/CD and Mic inputs. The signal out, to other cabinets, through the Link will also be affected. These controls do not affect signals coming into the cabi- net from the Link connections.

lllumination indicates that AC power is on and the fuse is functioning

12. Yellow Limit LED This indicates that the cabinet is operating at full power and the limiter(s) are actively reduc- ing the signal level. I's all right to operate in limiting as long as the clip light is not constantly on. The Limit light does not indicate low fre- quency processing action. There are separate limiters for the woofer and horn. This LED will indicate operation of either limiter.

13. Red Clip LED The ilumination of this LED indicates that the signal level is excessive and may cause distor- tion. Reduce mixer levels or turn down the Level control (on NX55P) to reduce clipping.

This turns the power On and Off to the cabi- net. Note; a cabinet that is turned off, but is one of the cabinets in a chain might cause hum (or buzz) in the other cabinets.

The mains fuse should never blow even in extreme operating conditions. À blown fuse will generally mean that excessive mains voltage has been applied or there's a serious fault with the unit. Self re-setting thermal switches are built into the power transformer as well as on the internal heat sink. These will not trip even under the most extreme operating condi- tions and are provided only for safety reasons. Thermal margins may be compromised when operating facing straight up, straight down or while operating in direct sunlight!

A note about unbalanced operation: When connecting an unbalanced source (such as a mixer with RCA outputs) to balanced inputs such as an ANX55P the best hum rejection can be achieved

by running a balanced connection right to the unbalanced plug. The retumm connection should

be connected to ground at the unbalanced plug. The NX55P does not connect the AC power ground drectÿy to the input signal ground. This will elminate most ground problems.

( EYEBOLT INSTALLATION

1. DESCRIPTION Many of the popular models in the Yorkville speaker cabinet line are now equipped with flying hardware for overhead suspension applications. Depending on the model, two or more internal braces have been provided for rigging purposes. Each brace contains two bolt holes and provides center-of-gravity fly-points for use with in-line or angular loads. Many of the models will support additional suspended cabinets according to their specified working load limits.

a) Using a 1/4-20 hex wrench, remove the flat head bolts from the top or bottom of the speaker enclosure to expose the tapped holes (on TX models, the flat head bolts are located within the track rails), as shown below. Be sure to keep these handy as they will be needed to seal the cabinet after the eyebolts are removed.

IMPORTANT!! USE ONLY LOAD RATED FORGED EYEBOLTS. THESE MAY BE PURCHASED THROUGH YORKVILLE SOUND OR ATM FLY-WARET“ TO INSURE CABINET-BRACING STRENGTH, MAKE SURE ALL FLY-POINTS ARE SECURED WITH EITHER AN EYEBOLT OR FLAT HEAD HEX BOLT.

b) Place a drop of thread-lock adhesive on the threads of the eyebolt and insert one into exposed hole. Tighten each eyebolt by hand until its fits snugly against the cabinet. Further tighten each eyebolt by rotating it another half turn. Be sure to insert eyebolts in the threaded hole directly in-line with the suspension cable. Always follow the eyebolt manufacturers installation and use instructions.

c) Suspend each cabinet according to working load calculations and practices recommended by the rigging hardware manufacturer.

ON MODELS WITH ONLY TWO TOP SUSPENSION POINTS THE SUPPLIED PULL BACK AT THE REAR OF THE BOTTOM CENTER PANEL OF THE CABINET IS NOT TO BE USED AS A SUSPENSION POINT. THIS POINT TO BE USED FOR PULL BACK PURPOSES ONLY.

Remove Flat-Head Bolt and $ replace with Forged Shoulder Eyeboit!

NX DO NOT Remove Flat-Head Bolts on the Side of Cabinet/s.
