Installation - MartinLogan ML-60i User Manual

Installation

NOTE: These instructions assume the mounting surface is of standard wood frame and
standard sheet rock construction. If you wish to mount the speakers to another type of
material you should contact a bonded contractor.
NOTE: See your local dealer for new construction pre-install brackets (sold separately).
NOTE: While it is possible to use a manual screwdriver for installation, we strongly sug-
gest using a power drill. To avoid damaging or breaking the clamps, set your drill to a
LOW setting. A high power setting is NOT necessary and may cause clamps to crack or
break from the added force. Such damage is not covered under warranty.
WARNING! Before installing check local building codes to verify com-
pliance with local regulations. WARNING! Before installing check for
obstructions behind drywall. To do this make a small hole, cutting at
a 45° angle (this will make the hole easier to patch if obstructions are
found). Only cut out the mounting hole after you have verified there are
no obstructions behind the dry wall. WARNING! Use only speaker cable
that is rated for in-wall use. The UL standard is CL2, CL3, and CM. The
CSA standard is FT4. WARNING! Turn your amplifier off before making
or breaking any signal connections.
Recommended tools:
• Stud finder
• Sharp pencil or pen

speakers, level the template before marking (Figs. 5a, 6a.1, & 6a.2).
4. Remove the template and cut out the opening with a drywall knife (Figs. 5b & 6b).
