70V speaker lines.

MOUNTING

The V-763 can be used on a desk or wall mounted. The front cover may be rotated

movement on a desk surface.

Key hole patterns are located on the inside rear surface of the enclosure for wall

mounting. When wall mounting, remove the front cover, mount and replace the front

cover. Use a 11/32" drill bit to drill the center hole and a 3/16" bit to drill either of

the outer holes.
