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

10. Refer all servicing to qualiﬁed service personnel. Servicing is required when the apparatus has been damaged in any way, such as 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.

11. The entire sound system must be designed in compliance with the current standards and laws regarding electrical systems.

12. When installing and using this apparatus, keep in mind the technical speciﬁcations indicated in the dedicated section of the manual.

13. Exposure to high sound levels can cause permanent hearing loss. The sound pressure level which leads to hearing loss varies considerably from one person to another, and depends on the duration of exposure. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has established the maximum sound pressure levels that can be with stood without causing damage, which are shown in the table below. According to the OSHA regulations, any exposure over the maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent potentially dangerous exposure to high sound pressure levels, anyone subjected to such levels must use suitable protection. When a EAW Commercial product capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones when the limits shown in the table are exceeded. Consult the speciﬁcations provided in the instruction manual to know the maximum sound pressure (SPL) the loudspeaker is capable of producing.

14. Rigging Precautions: When mounting or suspending EAW Commercial loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading, and any other contributing factors affecting the loudspeaker installation. The user must determine the proper design factor for speciﬁc applications and the required load rating of the connection to structure. Comply with all applicable federal, state, and local regulations.

EAW Commercial strongly recommends the following rigging system

practices:

• Documentation: Thoroughly document the mounting/rigging design with detailed drawings and parts lists.

• Analysis: Have a licensed structural engineer or other qualiﬁed professional review and approve the mounting/rigging design before its implementation.

• Installation: Use personnel experienced and qualiﬁed for mounting/ rigging loudspeakers in accordance with and in compliance with all federal, state and local regulations.

DANGER: Loudspeakers should be mounted or suspended only by persons with knowledge of the proper hardware and rigging techniques. Failure to follow these precautions may result in damage

to the equipment, personal injury, or death.

The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in

the literature accompanying the apparatus.

WARNING! This equipment has been designed to be installed by qualiﬁed professionals only!

There are many factors to be considered when installing professional sound reinforcement systems, including mechanical and electrical considerations, as well as acoustic coverage and performance. EAW Commercial strongly recommends that this equipment be installed only by a professional sound installer or contractor.

2. INTRODUCTION

The CIS961 and CIS991 are high-output ceiling-mounted loudspeakers, designed for ﬁxed installation into high ceiling plenum spaces or open structures. Utilizing four 5.25" LF cone woofers, four 4" MF cone woofers, and a horn-mounted compression driver, these loudspeakers deliver coherent point-source reproduction, as well as superior low-frequency dispersion. The result is superior full-range performance in any distributed loudspeaker system.

The CIS991 offers a broader high-frequency coverage pattern than the CIS961. (Please refer to the polar diagrams on pages 12–15.) Apart from this difference the two loudspeakers are identical, and this instruction guide covers both models.

The loudspeakers are supplied with an integral 70V/100V line transformer, rated to a maximum of 128 watts. Tap settings are adjustable by means of a recessed rotary switch on the front bezel, and allows selection of 128, 64, 32, and 16 watt taps at 70 V, and 128, 64, and 32 watt taps at 100 V. In addition, the transformer can be bypassed, presenting an 8-ohm load to low-impedance systems.

The white powder-coated 18-gauge steel back can is square in shape, and is designed to mount in a 24-inch ceiling grid. The back can includes a recessed euroblock input connector, with detachable mating plug, concealed behind a hinged metal cover plate. A ceramic screw-terminal block is also present. Four eye-bolts are supplied, and these need to be screwed into the back can by the installer, prior to suspending the assembly.

The bafﬂe/can assembly is shipped with the transducers installed. The powder-coated perforated steel grille is easily installed once the wattage tap has been selected.

Optional installation kits include a 4-piece cable kit (AC-CK) for suspension, and a 4-piece square trim ring kit (AC-TRK) that dresses the bafﬂe into suspended ceiling tile surrounds. (See page 16 for more details of these kits.)

3. FRONT PANEL FEATURES

1. MAIN ASSEMBLY

The loudspeaker is supplied with the drivers, crossovers, transformer, front bafﬂe, and rear metal can, all assembled in one unit. Do not disassemble this unit.

2. SELECTOR SWITCHES

Two rotary switches allow you to select the different transformer power taps, or to bypass the transformer. Use a ﬂat-ended screwdriver to make adjustments.

Turn off power to your ampliﬁer before making any adjustments.

Power Tap Selector

The loudspeaker can be used in 70 V or 100 V constantvoltage distributed systems.

For 70 V systems, select power taps from 16 W, 32 W, 64 W, and 128 W.

For 100 V systems, select power taps from 32 W, 64 W and 128 W.

Transformer/Direct Selector

In the transformer position, the loudspeaker uses an internal transformer with a choice of power taps. Set this if you are using a constant voltage ampliﬁer of 70 V or 100 V.

In the direct position, the transformer is bypassed, the power tap selector has no effect, and the loudspeaker presents an overall impedance of 8 ohm to a conventional power ampliﬁer.

3. FRONT GRILLE

The loudspeaker is supplied with the front grille not attached to the front bafﬂe. It comes with an insulating backing sheet already attached, to hide the bafﬂe and driver assembly from view.

4. GRILLE ATTACHMENT FITTINGS

The grille is attached to the main assembly after the selector switches have been set to the desired positions.

5. EYEBOLTS

Four included eyebolts must be securely ﬁtted to the metal back can for the purpose of suspending the loudspeaker. All four eyebolts must be used.

An optional mounting kit (AC-CK) is available that consists of four 10-meter lengths of cable and suitable connectors.

6. INPUT CONNECTORS

The input connections to the loudspeaker are accessed by moving two metal covers.

Phoenix (Euroblock) connector.

This four-pin input accepts a push-in connector for easy installation. Two terminals allow connection to the output of the power ampliﬁer, and two through-terminals are supplied to allow passing the power output to other loudspeakers.

Terminal strip.

This four-terminal connector allows easy connection of the audio lines by screw terminals. (This is also suitable for those installations requiring compliance with BS5839, part 8.) Two terminals allow connection to the output of the power ampliﬁer, and two through-terminals are supplied to allow passing the power output to other loudspeakers. Secure the connections with screws.

7. STRAIN RELIEF

This sliding screw clamp allows the wiring to and from the loudspeaker to be secured. The clamp can also be removed, and standard conduit ﬁttings (not supplied) connected.

CIS961 and CIS991 – 5

5. INSTALLATION

The loudspeaker is designed to be securely suspended from the four eyebolts ﬁxed to the metal back can. It can be suspended into the aperture of a standard suspended ceiling, or suspended from open plenum spaces.

Placement

There are two considerations when deciding where to place the loudspeaker:

Location: When installing the loudspeaker in a suspended ceiling with conventional ceiling tiles, the location of the loudspeaker is determined in part by the support grid of the suspended ceiling system.

Coverage: It is important to locate the loudspeaker in such a way that the sound is evenly distributed over the entire area. Keep in mind that the sound has farther to travel on the outside edge of the coverage area for each individual loudspeaker than directly below the loudspeaker, resulting in a decrease in SPL at the outer edges of the listening plane.

The loudspeaker placement should be designed such that the edges of the coverage pattern for each loudspeaker are at least touching. The more overlap that is provided (higher density coverage), the more SPL the system is capable of providing and the less variation in level as you move around the area. The downside of higher density coverage, of course, is that more loudspeakers are required for a given area.

Note: The EAW website contains free PC software to help you calculate the coverage for various loudspeakers and room sizes. Please visit www.EAW.com/downloads and look under "software" for the "coverage calculator."

MECHANICAL INSTALLATION

Note: Observe all local and national codes when

installing the loudspeaker.

Decide if you want to connect the loudspeaker to the ampliﬁer wiring before it is mounted in place, or if there is enough access to the rear panel afterwards.

You can suspend the loudspeaker using your own safetycertiﬁed equipment, or purchase the optional cable mounting kit AC-CK (more details are shown on page 16).

All four eyebolts must be used to suspend the loudspeaker, and the weight must be completely supported by the four suspension cables, and not by the ceiling frame.

If you are suspending the loudspeaker into a suspended ceiling, we recommend using the optional trim ring kit (ACTRK) to dress the loudspeaker surrounds into a standard suspended ceiling aperture 24" x 24" or 600 mm x 600 mm. More details of the trim ring kit are shown on page 18.

100 V connection example

Note: Observe all local and national codes when

installing the loudspeaker.

The loudspeaker is supplied with a strain-relief sliding clamp for securing jacketed cable or ﬂexible conduit.

If you are using 1/2 inch solid conduit or ﬂexible armored conduit, then the strain-relief can be removed and ﬁttings for securing solid conduit used instead (see page 9).

All connections to the loudspeaker must be made with the power ampliﬁer turned off.

Ampliﬁer connections

The following examples of 70 V and 100 V connections show an EAW Commercial CAM160, a typical mixer/ampliﬁer. Its speaker-level output is a screw terminal strip, with outputs for 25 V, 70 V, 100 V, Ground, and 4 ohm.

Installation with conduit

Setting the Taps

1. Remove the two screws holding the strain relief onto the rear cover, and remove the strain relief assembly. Keep it safe, in case you need it again.

2. Use a threaded conduit set-screw coupler (not supplied): For 1/2" conduit, use Thomas&Betts Steel City model TC221-SC (or UL listed equivalent).

3. If you are using ﬂexible conduit, then use Thomas&Betts Steel City model XC241 ﬂexible conduit ﬁtting (or UL listed equivalent).

4. Insert the new coupler into the hole exposed by removing the strain relief assembly. Fasten the coupler using the nut supplied with the coupler. It will help to remove the four side screws holding the cover plate assembly to the loudspeaker metal back can, so you can tighten the coupler's nut.

1. Set the tap selector switch, located on the front of the loudspeaker. In the example shown here, the tap is set to 32 W for a 70 Volt system, or 64 W for a 100 V system.

CAUTION:

the ampliﬁer. This may cause overheating to the ampliﬁer, and possible damage to your loudspeakers. To avoid overloading, make sure that the selected taps on the loudspeakers add up to no more than 80% of the rated power of the ampliﬁer being used.

2. If the speaker is being used in a low-impedance system, use the direct position. This bypasses the tapped transformer, and the ampliﬁer load will be an average impedance of 8 ohms. If you are using the thru connections to power other loudspeakers, note that the connections are in parallel. Make sure that the total impedance is not lower than the minimum impedance that your ampliﬁer can handle.

Make sure that you do not overload

5. Push the speaker cable through the conduit coupler, and insert your conduit into the coupler. Tighten the locking screw ﬁrmly. (Or twist ﬂexible cable onto the coupler shown in step 3.)

6. Attach the wires to the supplied Phoenix-type connector or the screw terminals as detailed on the previous page, and close and lock the input covers.

CAUTION:

never touch the bare wires coming from the output terminals of the ampliﬁer when it is switched on. When the connections have been made, make sure the input cover plates are correctly in place.

7. OPTIONAL KITS

Two kits are available for the loudspeaker. One is a mounting kit, and one is a trim ring kit. Please contact your dealer or EAW Commercial for ordering details.

AC-CK cable mounting kit

This kit consists of four 10-meter lengths of wire cable

with a crimped-on hook at one end. A small locking device

allows the length to be easily adjusted, so you can hang

the loudspeaker accurately in position in a suspended

ceiling, for leveling, or setting at an angle.

Loudspeaker suspended by four cables

4. Pull on the free ends to take up the slack and thus secure the hook/latch assemblies.

Note: The hexagonal locking

5. device has an arrow engraved on one side. This must be pointing down when installing.

You will need an assistant to help

hold the loudspeaker in position and support its weight.

Pass the free end of the cable through the outside

hole of the top end of a hexagonal locking device, through a loudspeaker eyebolt, and back up through the center hole of the locking device.

Close-up view of the hexagonal locking device

1. Find the location where you want the loudspeaker to be suspended.

2. Use suitable ﬂying points above the loudspeaker. These may be ceiling beams or suitable eyebolt hardware. (The dimensioned drawing at the bottom of page 10 shows the location of the eyebolts.)

3. Pass the free end of each cable over the support beam/structure and loop it through the hook/latch.

Fitting the hook/latch to a support

6. Pull up on the free cable ends until the loudspeaker is suspended at the correct height. (The hexagonal locking devices will stop the cables from pulling through and lowering the loudspeaker.)

Pull the free end to take up slack

7. To lower the loudspeaker, ﬁrst support its weight with the help of your assistant until the cables go slack. Use a small screwdriver to push up on the inner cylindrical sleeve inside the hexagonal locking device, and at the same time, gently feed more cable back through to increase the loop until the correct height is achieved.

Use a small screwdriver or point to push up the inner sleeve and release the cable

CIS961 and CIS991 – 17

AC-TRK ceiling-mount trim ring kit

The AC-TRK is a 4-piece square trim ring kit that dresses

the bafﬂe into suspended ceiling tile surrounds (24" x 24").

The trim ring kit can also ﬁt into 600 mm x 600 mm square ceiling tile surrounds by simply removing the small knock-off tab spacers along each edge.

The kit consists of four identical sides that can be joined together to form a square. This ﬁlls the space between the loudspeaker sides and the frame of the suspended ceiling.

PREPARATION AND ASSEMBLY

1. For installation into 24" x 24" ceiling surrounds, leave the tabs on and skip the next step.

2. For installation into 600mm x 600mm ceiling surrounds, remove all tabs from each of the sides. You can do this with a sharp knife or chisel, or by pressing the sides against the sharp edge of a table top, for example.

INSTALLATION

1. Gently drop the assembled square into the suspended ceiling, with the smooth sides facing down.
