Optional Accessories
ArenaMatch Utility loudspeakers are compatible with the RMU pan-and-tilt bracket (WBPWR-50) and various third-party pole-mount kits.
Note: The optional mounting accessories have not been assessed to EN 54-24 specifications.

Inspection & Maintenance

WARNING: The loudspeaker and all mounting components must be inspected annually by a qualified professional who is trained and certified in suspending loudspeaker systems. All rigging parts and components used in the suspension of the loudspeaker system should be visually inspected for signs of cracking, bending, water damage,  corrosion, de-lamination, or any other condition that could compromise the system’s integrity and create a dangerous falling hazard.
Maintaining Weather Resistance
ArenaMatch Utility loudspeakers are rated for direct-exposure outdoor installations. To maintain weather resistance, please observe the following precautions:

1. Before, during, and after installation, check the surface of the loudspeaker enclosure to ensure that the factory-applied, weather-resistant coating has not been damaged.
2. During installation, angle the loudspeaker at least 5° downward to reduce the potential of rain compromising the performance of the loudspeaker.
3. All mounting holes must be sealed off with steel screws (included with applicable accessories) or the included plastic plugs (pre-installed).
4. The gland nut that secures the loudspeaker cable is factory sealed. Do not remove the gland nut or the weather-resistant seal will be broken.
5. The loudspeaker is rated for direct-exposure installations, which means the grille is designed to withstand normal and wind-driven rain. The grille is not designed to withstand direct spraying of water from a hose or pressure washer.

CAUTION: If the above instructions are not observed, the weather- resistant integrity of your ArenaMatch Utility loudspeaker could be compromised.
**** For fire and evacuation notification applications, environmentally rated to IP33C per EN 54-24.
For general purpose audio installation applications, environmentally rated to IP55 per EN60529.

Recommended Tools

Installation

Input Panel
The input panel for all models is identical. They include a single screw- terminal barrier strip. Each terminal accepts a wire gauge of 10 AWG to 18 AWG.

1. Tap switch: Rotate to adjust the tap setting. Use a flathead screwdriver.
2. Barrier strip
   Securing the Wiring
   Feed the wiring through the gland nut on the bottom of the input panel. Once you are done wiring your loudspeaker, rotate the gland nut clockwise to seal the wire.  ighten the gland nut by hand until the wire is held firmly in place, then tighten the gland nut an additional quarter turn. Do not over- tighten.
   Note: Gland nut is rated IP68.
   CAUTION: If the gland nut is not properly fastened, water could get into the input panel and damage the loudspeaker.

Attaching the Input Panel Cover
ArenaMatch Utility loudspeakers are shipped with the rear input panel cover not installed. Once you’ve made input wiring connections, secure the cover over the input panel with the included M4 screws.
Note: The input cover can be rotated to support four different orientations. Always be sure the gland nut and wiring are facing downward.

Loudspeaker Pitch Angles
The maximum pitch angles for AMU loudspeakers when horizontally mounted with the included U-bracket are as follows:

| Wall-mounted| Ceiling-mounted
---|---|---
AMU105| –110°| –110°
AMU108| –110°| –110°
AMU206| –110°| –110°
AMU208| –110°| –110°

Note: The pitch angle is defined between the loudspeaker reference axis and the perpendicular axis to the mounting surface.

Mounting AMU Loudspeakers with the U-bracket

CAUTION: Before installation, determine the location and position of your AMU loudspeaker. Only remove the plastic inserts that are necessary for your installation. The plastic inserts are factory sealed to prevent water damage. If any insert is left unsealed after installation, the weather-resistant integrity of your loudspeaker could be compromised.

1. Choose a mounting location that will safely support the weight of the loudspeaker.

2. Remove packing materials and place the loudspeaker on the floor beneath the planned suspension point.

3. Using the included T3 square drive, remove the center plastic insert and one other insert (determined by your loudspeaker installation design) on each side of the loudspeaker.

4. Insert an M8 screw through a rubber washer and into the center threaded hole on each side of the loudspeaker. Do not tighten.

5. Hold the U-bracket in the mounting location and mark the holes.

6. Drill holes into the mounting surface using previously marked positions.

7. Attach the U-bracket to the building surface using appropriate fasteners (not included).
   CAUTION: For attaching U-brackets to a surface, choose fasteners that are consistent with all local building codes and requirements to support the weight of the loudspeaker.

8. Hang the loudspeaker on the bracket by lowering the M8 screws into the bracket slots, keeping the rubber washers between the bracket and the speaker enclosure.

9. Connect your wiring to your loudspeaker.

10. Feed the wiring through the gland nut on the input panel cover and tighten the gland nut (see Securing the Wiring on page 16).

11. Attach the input cover using the included M4 screws (see Attaching the Input Panel Cover on page 17).

12. Position the loudspeaker in your desired pitch angle.

13. Insert an M8 screw through the remaining open insert on each side of the loudspeaker.

14. Tighten the four M8 screws with a 10-millimeter socket tool using a torque not to exceed 13.6 to 20.3-newton ·meters (10 to 15-pound ·feet).

Rotating the High-frequency Waveguides

Note: Only the horizontal mounting orientation has been assessed to EN 54-24 specifications. The high-frequency waveguide in the AMU108, AMU206, and AMU208  loudspeakers can be rotated to provide the desired coverage pattern for horizontal or vertical loudspeaker mounting. These loudspeakers are assembled in the factory for horizontal mounting. To rotate the waveguide for vertical mounting, do the following.

1. Remove the screws (AMU108: 6 screws; AMU206/AMU208: 8 screws) from around the loudspeaker grille and remove the grille from the enclosure.
2. Remove the eight waveguide screws.
3. Pull the waveguide forward, rotate it 90°, and place it back into the enclosure.
4. Secure the waveguide using the screws removed in Step 2.
5. Reattach the grille using the screws removed in Step 1.

Recommended Amplifier Power
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (RMS) power rating, the dynamic range of the input-source material (crest factor), desired sound pressure levels, and other factors. As a general guideline, to optimize ArenaMatch Utility system performance, the following amplifier configurations are recommended.

Recommended Signal Processing
Digital signal processing (DSP) equipment is required for infrasonic protection, equalization, and voltage limiting protection.
Recommended loudspeaker DSP presets are available in Bose ControlSpace Designer software and are designed for use with Bose PowerMatch configurable professional amplifiers and ControlSpace ESP and EX processor hardware (sold separately).

Footnotes

1. Frequency response and range measured on-axis in an anechoic environment with recommended bandpass and EQ.

2. Bose extended-lifecycle test using pink noise filtered to meet IEC268-5, 6-dB crest factor, 500-hour duration.

3. AES standard 2-hour duration with IEC system noise.

4. Sensitivity measured in an anechoic environment with a recommended high-pass filter.

5. Maximum SPL calculated using sensitivity and power ratings, exclusive of power compression.

6. The specifications data was measured in an anechoic chamber, free-field. The reference plane is on the grille surface. The reference axis is perpendicular to the center of the grille surface.
   The horizontal plane contains the reference axis and is parallel to the horizontal axis defined by the longest baffle dimension.

7. Tested to IP55 per EN60529 when used in General Purpose Audio installation, not for Fire and Evacuation notification applications. Notified Body certified by UL per the EN54-24 standard for an IP33C rating, acceptable for use in a Fire and Evacuation Notification System application.
