Description

With the NXL44-A, RCF has provided a unique and powerful two-way line source, with the sound delivered from three 10” neodymium woofers and a 1.4” driver with 3“ voice coil on a asymmetrical waveguide. All are perfectly tuned to deliver remarkably uniform coverage and an extended frequency range. Precision controlled by an on-board DSP and driven by a two-channel digital amp, the NXL44-A delivers very natural sounding response and high SPL for professional live sound reinforcement. The horn’s design is asymmetrical so it projects sound energy with great accuracy, thereby avoiding undesired reflections. The enclosure always remains vertical – it does not have to be tilted or aimed in any way that would adversely affect its stability.

UNIQUE FEATURES

  • Sleek low-profile design
  • True line source with extended reach
  • Asymmetrical horn for optimized coverage
  • Much greater intelligibility than spherical sources
  • Far more uniform SPL across the audience area

HIGH PERFORMANCE

The advanced technology of RCF’s powered line arrays has been delighting audiences and users for many years. Paired with state-of-the-art DSP-driven controllers and digital power amps, these systems raise the bar for reliability and performance.

There are many situations where users wish they had a sound system that combines the benefits of line array technology – higher levels of direct rather than reflected sound, greater range and more uniform distribution – with the handling ease of two-way cabinets.

MAXIMUM EFFICIENCY

The NXL44-A is a true active high-power ready-to-use two-way array system, equipped with a high efficiency digital amplifier that delivers superior SPL, while reducing energy requirements. The integrated processing and the cabling reduction will make the set-up faster and easier and, thanks to its compact size, the space requirement is reduced to the minimum.

DSP PROCESSING & AMPLIFIER

The NXL 44-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.

INPUT / LINK

MAIN XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line level signals from a mixing console or other signal source.

LINK XLR OUTPUT. The output XLR male connector provides a loop trough for speakers daisy chaining.

VOLUME KNOB

Controls the volume of the power amplifier. The control ranges from – (maximum attenuation) to the MAX level (maximum output).

STATUS INDICATORS

POWER INDICATOR. Power on indicator. When the power cord is connected and the power switch is turned on this indicator lights green.

SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main XLR input.

LIMITER INDICATOR. The amplifier has a built in limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the peak clipping circuit is active the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level. The amplifier has a built in RMS limiter. If the RMS limiter is active the LED lights red. The RMS limiter has the purpose to prevent damages the transducers. The speaker shall never be used with the limit indicator red, continuous operation with the RMS protection active can cause damages to the speaker.

EQ SWITCH

“Boost” equalization is a loudness recommended for background music applications, when the system plays at a low level or when two systems are coupled. For all other applications “Flat” equalisation is recommended.

MIC/LINE SWITCH

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.

AC PANEL

AC POWERCON RECEPTACLE.
The NX L44-A uses a POWERCON locking 3-pole AC mains. Always use the specific power cord provided in the package.

AC POWERCON LINK RECEPTACLE.
Use this receptacle to link one or more units. Always make sure that the maximum current requirement does not exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF SERVICE CENTRE.

POWER MAIN SWITCH.
The power switch turns the AC power ON and OFF. Make sure that the VOLUME is set to – when you turn on the speaker.
