Never tilt the assembly.

There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).
Hearing loss.
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure level.

DESCRIPTION

NXW 44-A – THE NEXT GENERATION OF SOUND
The NXW 44-A sets a new milestone in column speakers. RCF engineers have merged purpose-designed transducers with constant directivity, FiRPHASE processing, and newly added Bass Motion Control algorithms, all driven by a 2100W amplifier. Durably built in a rugged baltic birch plywood cabinet with ergonomic handles on each side, NXW 44-A speaker is unobtrusive, flexible, and deliver remarkable audio performance to any professional audio application.
NXL/NXW series consists of full-range column array speakers ideal for high- powered portable and installed professional applications where size is a critical factor. The sleek column design and the rigging flexibility make it a smart choice for a wide range of sound applications. It can be used alone, on a pole, or paired with a sub, vertically coupled for improved vertical coverage, and can also be flown or truss-mounted using the included rigging points and special accessories. From the cabinet to the final texture and the rugged protective grille, NXL/NXW Series offers maximum strength for intensive use on the road and can be used for fixed installation.

REAR PANEL FEATURES AND CONTROLS

1. PRESET SELECTOR This selector allows to select 3 different presets. By pressing the selector, the PRESET LEDS will indicate which preset is selected.
   LINEAR – this preset is recommended for all regular applications of the speaker.
   BOOST – this preset creates a loudness equalization recommended for background music applications when the system plays at a low level
   HIGH-PASS – this presets activates a 60Hz high-pass filter for the correct coupling of the NXW 44-A with subwoofers not provided with their own internal filter.

2. PRESET LEDS These LEDs indicate the selected preset.

3. FEMALE XLR/JACK COMBO INPUT This balanced input accepts a standard JACK or XLR male connector.

4. MALE XLR SIGNAL OUTPUT This XLR output connector provides a loop trough for speakers daisy chaining.

5. OVERLOAD/SIGNAL LEDS These LEDs indicate
   The SIGNAL LED lights green if there is a signal present on the main COMBO input.
   The OVERLOAD LED indicates an overload on the input signal. It is okay if the OVERLOAD LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level avoiding distorted sound. Anyway, the amplifier has a built-in limiter circuit to prevent input clipping or overdriving the transducers.

6. VOLUME CONTROL Adjusts the master volume.

7. POWERCON INPUT SOCKET PowerCON TRUE1 TOP IP-Rated power connection.

8. POWERCON OUTPUT SOCKET Sends the AC power to another speaker. Power link: 100-120V~ max 1600W l 200-240V~MAX 3300W

BEFORE CONNECTING THE SPEAKER
On the rear panel you will find all the controls, signal and power inputs. At first verify the voltage label applied to the rear panel (115 Volt or 230 Volt). The label indicates the right voltage. If you read a wrong voltage on the label or if you can’t find the label at all, please call your vendor or authorized RCF SERVICE CENTRE before connecting the speaker. This fast check will avoid any damage.
In case of need of changing the voltage please call your vendor or authorized RCF SERVICE CENTRE. This operation requires the replacement of the fuse value and is reserved to an RCF SERVICE CENTRE.

BEFORE TURNING ON THE SPEAKER
You can now connect the power supply cable and the signal cable. Before turning on the speaker make sure the volume control is at the minimum level (even on the mixer output). It is important that the mixer is already ON before turning on the speaker. This will avoid damages to the speaker and noisy “bumps” due to turning on parts on the audio chain. It is a good practice to always turn on the speakers at last and turning them off immediately after their use. You can now turn ON the speaker and adjust the volume control to a proper level.

PROTECTIONS
This speaker is equipped with a complete system of protection circuits. The circuit is acting very gently on audio signal, controlling level and maintaining distortion at acceptable level.
