MOUNTING
The speaker is provided with a 3-way omni-directional adjustable mounting bracket. The wing nut and the lock

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. 1= Common 2= Positive.
