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 (5.3 mm2) to 18 AWG (0.8 mm2).

1. Tap switch: Rotate to adjust 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. Do not over-tighten. Gland nut is rated IP68.

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.

Loudspeaker Pitch Angles

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

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

Mounting

1. Your loudspeaker installation design) on each side of the loudspeaker. loudspeaker. Do not tighten.
2. Hold the U-bracket in the mounting location and mark the holes.
3. Drill holes into the mounting surface using previously marked positions.
4. Attach the U-bracket to the building surface using appropriate fasteners (not included)
5. 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.
6. Connect your wiring to your loudspeaker.
7. Feed the wiring through the gland nut on the input panel cover and tighten the gland nut.
8. Attach the input cover using the included M4 screws (see Attaching the Input Panel Cover on page 8).
9. Position the loudspeaker in your desired pitch angle.
10. Insert an M8 screw through the remaining open insert on each side of the loudspeaker.
11. Tighten the four M8 screws with a 10-millimetre 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

To rotate the waveguide for vertical mounting, do the following.

1. Remove the screws (AMU108 and AMU108-120: 6 screws; AMU206, AMU208, and AMU208-120: 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.

Amplifier Power

Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer’s long-term (or RMS) power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels, and other factors.

Technical Specifications

Footnotes

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