INSTALLATION
Note:
The speakers should be mounted on a fl at surface to form a good seal between the
speaker fl ange and the mounting surface.
1. Using the supplied template make a 7
3
⁄
4
-inch
(197mm) cutout for the OH-T7 or a 9
1
⁄
2
-inch
(241mm) cutout for the OH-S7. It is not neces-
sary to remove fi berglass insulation that may be
behind the wall.
2. Run wire from amplifi er to cutout. Allow an extra
foot of wire at the cutout.
3. Remove the speaker grille. Carefully pry up one
side with an awl or small screwdriver.
The OH-S7 and OH-T7 have heavy-duty spring-loaded push terminals for their input connec-
tions. The terminals will accept wire or pins up to
5
⁄
32
-inch in diameter.
4. If connecting with bare wire, strip the wire so that
approximately
1
⁄
2
-inch is exposed. Twist the wire
into a bundle so that there are no stray strands.
Push the end of the terminal to expose the hole in
the side of the terminal. Then insert bare wire into
the hole and release.
5. The insulation of the wire will have a stripe or ribs
on one side. Use this marking to ensure the + (red) terminal of the speaker is connected to
the + terminal of the amplifi er and the
– terminal of the speaker is connected to the – terminal of the amplifi er.
Warning!
To prevent electrical shock, always switch off the amplifi er or receiver when making
connections to the speaker system.
6. Place the speaker in the hole. Rotate
the speaker until the tweeter waveguide
is aimed in the desired direction. Use
a Phillips screwdriver to tighten the
four pivoting mounting arms. Avoid
overtightening, as this could break the
mounting arms or damage the ceiling surface.
7. Install the grille. Press fi rmly arund the outer edge of the grille
to seat it fi rmly in place.
