Mounting

INSTALLATION INSTRUCTIONS

CAUTION: Mounting the AH loudspeaker requires two people, unless it is possible to safely clamp the speaker in position for alignment before mounting.

The bracket may be removed from the speaker for installation convenience. When re-attaching speaker to bracket be sure to tightly secure speaker mounting bolts. Thread locking compound should also be used in this operation.

1.Choose the bracket mounting holes best suited for the surface you are mounting to. For best stability the 58" (16mm) diameter outer keyhole slots are recommended.

2.When using these mounting holes 12" (grade 5 hardware minimum) hardware should be used with proper fl at and lock washers. Remember to use thread- locking compound on all parts.

3.Use the dimensions noted on the illustration to mark the points where the starting hole should be drilled.

4.Choose appropriately sized bit and drill holes.

5.Attach speaker bracket, using bolt, fl at washer, and lock washer as shown and re-attach loudspeaker to bracket.

6.Secondary (safety) suspension point: Use a load rated cable or steel chain (capable of holding the speaker should it come loose from the primary mounting point). This cable or chain assembly should be attached to at least (2) of the drop forge eyebolts provided on the AH speaker and secured to the mounting surface via approved, load rated hardware.

Lastly, the AH99-8ST stands out with its wide coverage pattern and increased power handling capabilities, designed to distribute sound evenly across larger areas. This makes it an ideal choice for installations where wide dispersion and volume control are key, such as gymnasiums or large assembly halls.
