YORKVILLE NX550P DetailsNX550P Manual (PDF File)NX550P Overview The NX550P uses a combination of amplifier technologies to create the best combination of lightweight enclosure and high quality sound. Capitalizing on the NX350's moulded cabinet technology, as well as totally new switching power amplification and Neodymium drivers, the 550-watt bi-amped NX550P weighs in at just 47lbs (21.4kg) ...the lightest in its class by a longshot. This lightweight, high tech loudspeaker is a remarkable performer. All NX series enclosures are manufactured using tough, light weight (47lb/21.4kg for the NX350), low resonance variable density composite materials. In addition they are UV and moisture resistant. Furthermore, the enclosure itself has been moulded for maximum versatility. The newly designed NX550) features a 80º x 50º horn and an improved monitor angle, making it ideal for mounting in arrays, or for use as a floor monitor. Add to this the more durable, smoother finish due to an improved moulding process, which completely eliminates all release marks as well as the screw flutes, which are used to mount the front baffle in place and improved port tuning, specifically tuned for the enhanced bass response of the NX550P. Recessed input jack plate, pole mount and flypoints for either eyebolt installation or optional NX Series Flyware are standard. The unique enclosure design means the NX550P can easily be used as a front of house PA loudspeaker, or as a wedge monitor. It comes equipped with flying hardware and has an incorporated stand mount adapter. The NX550P has incorporated some unique design ideas not seen in any other active loudspeakers, much less any active loudspeaker that performs as well as this. The loudspeaker uses a switching power amplifier for the bottom end to further reduce weight, and a two-tier class H amp for the 1" horn driver. 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 isn''t typically seen in a product like this, however we found when designing the NX550P, the advantages (lower weight, more efficiency, higher headroom and lower operating temperature) made it a perfect choice for powering the top end. A newly designed switching amplifier drives the neodymium woofer in the NX550P. This low frequency amplifier uses Class D switching technology to reduce overall weight of the amplifier section. This combination keeps distortion to a minimum while reducing the heat dissipation to a level low enough to eliminate the need for heavy heatsinks for the overall power stage. With no need for heatsinks, the NX550P is ideally suited for use as a powered monitor, installed near a wall or roof using the optional NX Flyware or as the core of the ultimate compact and lightweight FOH system. The NX550P 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. We''ve found competitive powered speakers with large finned heatsinks need to be operated vertically and with clearance to ensure proper heat dissipation and ventilation, a problem not found in the NX550P. 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 NX550P 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 NX550P 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 NX550P'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 NX550P'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 NX550P 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 NX550P a more efficient and effective vocal monitor. The NX550P 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.) NX550P Features NX550P Specifications Item ships directly from manufacturer.
