IMPORTANT SAFETY INSTRUCTIONS

Watch for these symbols:
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s  enclosure, that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the  literature accompanying the appliance.

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two  blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an  electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the  cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged,  liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15. Warning: to reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

16. Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment.

17. To completely disconnect this apparatus from the ac mains, disconnect the power supply cord plug from the ac receptacle.

18. The mains plug of the power supply cord shall remain readily operable.

19. This apparatus contains potentially lethal voltages. To prevent electric shock or hazard, do not remove the chassis, input module or ac input covers. No user serviceable  parts inside. Refer servicing to qualified service personnel.

20. The loudspeakers covered by this manual are not intended for high moisture outdoor environments. Moisture can damage the speaker cone and surround and cause  corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct moisture.

21. Keep loudspeakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term  exposure to intense ultra-violet (UV) light.

22. The loudspeakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum, the speaker may move due to its acoustical  energy output.

23. Precautions should be taken to assure that the speaker does not fall off a stage or table on which it is placed.

24. The loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew and  audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.

INTRODUCTION

The AX4CL Line Array is a passive system equipped with four 2.5” neodymium transducers with waterproof cones, designed for portable and permanently installed  applications where high power and clarity are needed. The aluminum frame box structure ensures lightweight and strength, while the shape features a back-loaded  transmission line design with clean mid-bass reproduction and natural cardioid behaviour. The wide horizontal dispersion make the system flexible and adaptable to many  different applications.
The AX4CL line array module has been designed to be used as a stand-alone or multiple column system in fixed or mobile installations, frontfill applications and low-profile  stage monitoring solutions.

INPUT & LINK – Both connectors at the top and the bottom of the AX4CL can operate as input or link, to connect an appropriated processed amplifier or to link the  column to a second one. The AX4CL does not include an internal passive crossover for filtering the signal, but only an internal protection that excludes the internal speaker  to protect them from excessive input power. The protection should not trip with a typical music program, but only with a massive and constant power signal, like a feedback.  The connections are the following:

| INPUT – LINK
---|---
NL4 pin number| internal connection
| 1+| + speakers (pass thru link speakon)
| 1-| – speakers (pass thru link speakon)
| 2+| + no connection (pass thru link speakon)
| 2-| – no connection (pass thru link speakon)

WARNING:
The maximum quantity of AX4CL that can be linked together depends by the load capacity of the appropriate processed amplifier.

BASIC INSTALLATION INSTRUCTIONS

WARNING! CAREFULLY READ THE FOLLOWING INSTRUCTIONS AND CONDITION OF USE:

• This loudspeaker is designed exclusively for Professional audio applications. The product must be installed by qualified personal only.
• Proel strongly recommends that this loudspeaker cabinet be suspended taking into consideration all current National, Federal, State and Local regulations. Please contact  the manufacturer for further information.
• Proel do not accept any liability for damage caused to third parties due to improper installation, lack of maintenance, tampering or improper use of this product,  including disregard of acceptable and applicable safety standards.

Use these holes for the column speaker splay angle:

Each of the following examples has some symbols at the connection points: these symbols indicate if a splay angle is allowed or is prohibited for safety or acoustical reason:

FLOOR INSTALLATION WITH KPTPOLEAX16CL POLE ADAPTER
The KPTPOLEAX16CL is used in combination with the KP210S or DHSS10M20 pole on the KPTFAX16CL floor stand as base.
WARNINGS:

• The ground where the KPTFAX16CL floor stand is placed needs to be stable and compact.
• Adjust the feet so to put the KTPFAX16CL perfectly horizontal. Use a spirit level to obtain the best result.
• Always secure ground stacked setups against movement and possible tipping over.
• A maximum of 4 x AX4CL speakers are allowed to be installed over a KPTFAX16CL with pole serving as ground support.
• The column must be setup with 0° aiming.

FLOOR AND FRONT FILL INSTALLATION USING KPTFAXCL FOAM STAND

WARNINGS:

• KPTFAX4CL can be used in front-fill or monitor applications on stage.
• The ground where the KPTFAXCL foam stand is placed needs to be stable and compact.
• When using this support for frontfill application, place it on a stable surface. If it is placed on a front line subwoofer, it must be secured to it using a strap, because the subwoofer vibrations could cause it to fall to ground.

WALL INSTALLATION USING KPTWAX16CLL BRACKETS
WARNINGS:

• No hardware is supplied to install the KPTWAX16CLL to the walls: the hardware to be used depends on the wall structure. Use always the best hardware available,  taking in consideration the whole weight of loudspeakers and accessories.
• Brackets MUST be installed by qualified personnel in accordance with safe installation practices.
• A single AX4CL or 2x AX4CL speakers can be installed using the KPTWAX16CLL as top and bottom wall brackets.

AX4CL CONNECTION EXAMPLES
The following examples shows all the possible connections between a dedicated amplifier and the AX4CL column speaker, please note the amplifier must be equipped with a  DSP and specifically designed preset.

1 x AX4CL

2 x AX4CL

4 x AX4CL
