Installation
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, AMU108-120, AMU206, AMU208, and AMU208-120
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 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.
Recommended Amplifier Power
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (or
RMS) power rating, 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.
Loudspeaker
AMU105
AMU108
AMU108-120
AMU206
AMU208
AMU208-120
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 Professional ControlSpace Designer software
and are designed for use with Bose Professional PowerShareX configurable professional amplifiers and
ControlSpace ESP and EX processor hardware (sold separately).
