NEXT-PROAUDIO LA122W (01) PDF Document

NEXT-PROAUDIO LA122W systems are capable of producing extremely high sound pressure levels. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for a long period. Never stand close to loudspeakers driven at high levels.

Always ensure that the floor or structure where the stack will be placed is even and can withstand the weight of the complete stack.

Do not stack speakers too high, especially outdoors where winds could topple the stack.

Place cables in a way that they do not present a trip hazard.

Do not place any objects on top of the stack, as they can fall accidentally and cause injuries.

Do not try to operate the NEXT-PROAUDIO LA122W under heavy rain or moisture. It is weather-resistant but not completely weather-proof.

Do not expose the NEXT-PROAUDIO LA122W to extreme heat or cold conditions to prevent component damage.

Inspect all components and all hardware for any signs of damage or missing parts. If you find any damaged, corroded, or deformed parts, do not use them, replace them immediately. Do not use hardware that isn’t load rated or that its rating is not enough to handle the system’s weight with a good safety factor.

The NEXT-PROAUDIO LA122W system installation should only be carried out by qualified personnel.

Always use adequate protective clothing and equipment to prevent possible injuries. Only install the systems on solid, levelled ground and isolate the surrounding area during installation and operation to prevent general public presence near the systems.

Examine the NEXT-PROAUDIO LA122W carefully for any signs of possible transit damage and inform your dealer immediately if any such damage is found.

The NEXT-PROAUDIO LA122W is connected through Neutrik SpeakON NL4FC plugs.

The 4 pins of the two Neutrik NL4 SpeakON sockets are wired in parallel within the enclosure.

The following table details the wiring pinout:

No, the NEXT-PROAUDIO LA122W line array elements are bi-amp only and were not designed to work in full-range.

Selecting a cable consists of calculating the correct cable section in relation to the load impedance and the required cable length.

The NEXT-PROAUDIO LA122W has a simple and intuitive four-point rigging system. It has 2 articulated joints on the front and 2 rear adjustable joints.

The angle is adjustable from 0 degrees to 8 degrees relative to the upper element. The NEXT-PROAUDIO LA122W is a wider dispersion (15 degrees) element.

Never use any lock pins but the ones supplied by NEXT-PROAUDIO. These pins are built to withstand the system’s weight with a good safety factor and are built with very specific dimensions.

Pull the joints out, insert them on the frame and lock them with locking pins. Insert two locking pins on the front joints, and one on the rear joints. To obtain a 0 degrees alignment between the frame and the NEXT-PROAUDIO LA122W, you need to lock the rear joints on the upper hole. Verify that the locking pins are locked.

Insert the locking pin in the desired angle hole on the rear joints and verify that the locking pins are locked.

The NEXT-PROAUDIO LA122W when coupled and locked on the 8 degrees position, will have a 11.5 degrees positioning relative to the NEXT-PROAUDIO LA122. The 15 degrees positioning is only effective between NEXT-PROAUDIO LA122W units.

The technique should be to segment the system in order to identify the faulty component: signal source, controller, amplifier, loudspeaker or cable.

A simple sweep with a sine wave generator at a fairly low level can help identify if there are vibrations due to loose screws, air-leak noises, vibrations due to a badly positioned front grille, foreign objects in the cabinet, internal wire/material touching the diaphragm, or if the speaker is not connected or phase reversed.
