The RCF NXL 24-A is an active column speaker array system composed by 4 x 6" high power woofers and a 2.5" voice coil compression driver loaded from a waveguide on a 100° x 30° constant directivity horn. This particular design permits coherent sound dispersion minimizing lobing in a very compact enclosure.
The wide coverage horizontal angle and the controlled vertical dispersion allow correct sound reproduction serving a wide area and assistance in limiting feedback and reverberated sound.
The amplifier delivers 1400 Watt and is controlled by a DSP that takes care of crossover, equalization, phase alignment, soft limiting and speaker protections. Equalizations are available to operate with a single column or in pairs.
At the core of NXL 24-A design is the new ND 640 compression driver loaded from a waveguide to a constant directivity 100° x 30° horn. The ND 640 large format compression driver is one of the key advantages of the NXL 24-A, the 2.5" voice coil allows a crossover point of 800Hz and therefore almost all of the vocal range can be produced by this driver. This allows better coverage and dispersion control, and superior efficiency. All Compression drivers and Transducers are precision built taking advantage of RCF’s superior moulding, assembly technologies and a wealth of professional knowledge and experience dedicated to achieving extremely high standards.
The NXL 24-A is powered by a 1400W peak power digital amplifier, split 400W for the HF and 1000W for the LF. A new generation DSP handles all the processing within the cabinet and allows adjustment for a single column application or HF close coupling application.
NXL 24-A amplifier deliver ultra fast attack, realistic transient response and impressive audio performance. It presents SMPS power supply section in order to produce maximum output and minimum transportation weight. A useful Mic/Line switch to adjust the input sensitivity is provided. When used just for speech, the Mic setting allows to use a microphone directly with the speaker. Set the selector to Line when using the speaker for live music or playback. An easy to reach volume knob on the back allows to set the overall volume of the speaker according to its application. Three status LEDs - Power / Signal / Status - are provided for monitoring the system.
Using its accessory it is possible to fly 2 NXL 24-A in HF close coupling configuration with a choice of three possible angles (0°, 15°. 20°). It is also possible to pole mount the system and thanks to a second pole mount on top of the cabinet it is possible to couple two of them.
The cabinet is equipped with four rubber protections and two aluminum side handles for rental use and easy transportation. NXL 24-A cabinets are in Baltic Birch Plywood enclosure with internal structural metal bracings offering the maximum reliability and strength for an intensive use.
