Installation
The MONITOR MR3ST can be mounted using
the optional mounting brackets. These include
the following:
MA3-5 Articulated surface mount
MA3-6 U-bracket
MA-7B Wall-mount support bracket
WARNING: Consult a professional rigger or
structural engineer prior to suspending
loudspeakers from a structure not intended
for that use. Always know the working load
limit of the structure supporting the
loudspeaker array. Always make sure that
the rigging hardware minimum rating is at
least five times the actual load.
Connections
The spring-loaded speaker terminals are
designed to accept bare wire, up to a
maximum of 18 gauge. Strip 1/4” of insulation
off the end of the speaker wire, press in the
tab, and insert the bare wire into the hole.
When you release the tab, the wire is locked in
place. Make sure there are no stray strands of
wire outside the terminal connection.
