NX55P Active Full Range Loudspeaker
Using the popular nx20 as a base, adding 550 Watts of
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
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
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
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.
