Assurez que lappareil est fourni de la propre ventilation. Ne procédez pas à l'installation près de source de chaleur tels que radiateurs, registre de chaleur, fours ou autres appareils (incluant les amplificateurs) qui produisent de la chaleur. Les dispositifs marqués d'une symbole "d'éclair" sont des parties dangereuses au toucher et que les câblages extérieurs connectés à ces dispositifs de connection extérieure doivent être effectivés par un opérateur formé ou en utilisant des cordons déjà préparés. Ne pas enlever le dispositif de sécurité sur la prise polarisée ou la prise avec tige de mise à la masse du cordon d'alimentation. Une prise polarisée dispose de deux lames dont une plus large que l'autre. Une prise avec tige de mise à la masse dispose de deux lames en plus d'une troisième tige qui connecte à la masse. La lame plus large ou la tige de mise à la masse est prévu pour votre sécurité. La prise murale est désuète si elle n'est pas conçue pour accepter ce type de prise avec dispositif de sécurité. Dans ce cas, contactez un électricien pour faire remplacer la prise murale. Évitez d'endommager le cordon d'alimentation. N'UTILISEZ PAS L'APPAREIL si le cordon d'alimentation est endommagé. Débranchez cet appareil durant les orages ou si inutilisé pendant de longues périodes. Alimentation Hazards Risque Power Cord Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. The AC supply cord should be routed so that it is unlikely that it will be damaged. If the AC supply cord is damaged DO NOT OPERATE THE UNIT. Unplug this apparatus during lightning storms or when unused for long periods of time.

NX55P Active Full Range Loudspeaker Using the popular nx20 as a base, adding 550 Watts of bi-amped power and topping-it-off with aadvanced 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 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 NX55P's can easily be used in any orientation (close to walls, floors and in close arrays with multiple cabinets). Competitive active loudspeakers, with large finned heatsinks, need to be operated vertically and with plenty of clearance (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 sweeping 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. Extremely fast and accurate limiting is in place to protect the speaker components. As a bonus, the NX55P 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 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 (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 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. 1 Features · Ultra-clear reproduction throughout the whole bandwidth · High efficiency, high tech, 550 Watt Biamped 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 4.
