nx520p Active Full Range Loudspeaker

Using the popular nx20 as a base, adding 550 Watts of bi-amped power and topping-it-off with advanced signal processing, the nx520p 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 diaphragm 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 dissipation. In fact, to a level low enough to eliminate the need for heavy heatsinks. The advantage of this unique combination of two-tier and Class D amplification has reduced extraneous heat to the point that nx520p's can easily be used in any orientation (close to walls, floors and in close arrays with multiple cabinet Competitive active loudspe large finned heatsinks, nee vertically and with plenty of ensure proper heat dissipa Since you have more vers orientation of the enclosure becomes ideal for flying in point-source concert sound designers took extra care fight clusters overheating v

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 sweeping filters. If the nx520p 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. Extremely fast and accurate limiting is in place to protect the speaker components.

As a bonus, the nx520p has a built in mixer! This 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 source (up to a maximum of 50 nx520ps). If desired, you can combine a pair of the nx520p'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 (optimized 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 individually adjusted in level. This is invaluable in applications where large numbers of cabinets are used such as in clusters or in trade show applications (or when nx520p's are used as repeater cabinets or for side fill). The 100Hz high pass filters allow the nx520p to be used more efficiently with any active subwoofer.

Operation

The nx520p is a bi-amped powered full-range loudspeaker with a built-in two channel mixer. Multiple nx520p cabinets may be connected through the Link option. If you're using the nx520p with an external mixer, the internal mixer can be disabled. The built-in mixer has a microphone input and two (combined) 14 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 nx520p with a subwoofer.

Mic Input

Any regular microphone can be inserted into the Mic input. Phantom power is built-in for condenser microphones.

Line/CD inputs

The Line/CD inputs allow line level sources such as CD players or Cassette decks to be directly connected. These inputs are combined to allow the blending of stereo sources into mono. The inputs are also balanced to help reject hum (when used with balanced cables). This input may be used to allow operation from lower-level Line inputs (as opposed to the Link jacks). It may also be used to accommodate a greater range of level adjustment than the nx520p Level control allows (for example a cabinet in a chain of cabinets that needs to operate at much reduced level).

Link

These parallel jacks allow multiple nx520p cabinets to be connected together. The Link Jacks are the correct input to use when driving the nx520p from an external mixer. The Link Jacks operate at line level (+4 dBv) to achieve full power. The nx520p 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 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. Jacks marked LINK OUTPUT are connected in parallel with the LINK INPUTS and are provided for convenience to connect downstream cabinets. Link inputs may also be used as outputs and link outputs may be used as inputs.

Level Control

This control allows cabinets, linked in a chain, to be individually adjusted over a +/- 6 dB range. This control does not adjust the level of the Link jacks.

LF Rolloff

For operation with a subwoofer, the LF Rolloff switch shuts off the low frequency boost and filters out signals below 100Hz . It's not necessary 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.

Mixer On/Off

This switch turns the internal mixer On or Off. When the Mic or Line/CD inputs are used, this switch must be set to the On position. If these inputs are not being used, the mixer should be turned Off. This will help prevent the mixer from loading the Link, or the Internal Mixer, and contributing noise to the system. The internal mixer should not be used when a source other than another nx520p or similar cabinet is connected to the LINK jacks. Remember, a maximum of three mixers, in a chain of cabinets, should be used! A much larger number of cabinets may be used with the nx520p mixers disabled on the additional cabinets.

Mic control

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.

Line/CD control

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 connected simultaneously.

Treble and Bass controls

These controls affect the signals from devices 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 cabinet from the Link connections.

Green PWR LED

Illumination indicates that AC power is on and the fuse is functioning.

Yellow Limit LED

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

Red Clip LED

The illumination of this LED indicates that the signal level is excessive and may cause distortion. Reduce mixer levels or turn down the Level control (on nx520p) to reduce clipping.

POWER switch

This turns the power On and Off to the cabinet. 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.

Fuse

The mains fuse should never blow even in extreme operating conditions. A 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 conditions 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 nx520p, the best hum rejection can be achieved by running a balanced connection right to the unbalanced plug. The return connection should be connected to ground at the unbalanced plug. The nx520p does not connect the AC power ground directly to the input signal ground. This will eliminate most ground problems.
