INSTALLATION INSTRUCTIONS

MOUNTING

The speaker is provided with a 3-way omni-directional adjustable mounting bracket. The wing nut and the lock pin allow
360˚ rotation and 130˚ vertical movement. Additional adjustment is provided between the bracket and speaker by means
of the 1⁄4" bolt. For ease of installation, the base can be separated from the speaker by removing the 1⁄4" wing nut and
locking pin.

CONNECTION

Audio source line-connection is made to the screw terminals. To insure reliability, these
special terminals are designed with wire retainers. Phasing is indicated throughout the
communications system and attained by maintaining polarity utilizing the numbers “1”
& “2” cast into the speaker housing. (#2 is recommended for positive terminal).
