WARNING: Do not mount and finish over the speaker until
you have selected the necessary tap setting to achieve the desired
volume level. After selecting a given tap, play the speaker with
an actual audio signal to verify the speaker provides adequate
volume. If necessary, re-select a lower or higher tap setting.

Using a #2 Phillips head screwdriver remove the two screws
securing the terminal cover plate.

When using speaker wire without conduit, run the wire
through the hole on the terminal cover plate. Wire needs to
be clamped as required by national or local codes. Connect
the wires to the terminal block being certain to connect the
positive wire to terminal marked + and the negative wire to
the terminal marked – .
When using conduit attach the conduit connector to the
terminal cover plate then connect the wires to the terminal
block being certain to connect the positive wire to terminal
marked + and the negative wire to the terminal marked – .
Using a flat head screwdriver set the transformer tap to
the correct tap setting for your installation. We strongly
recommend testing the system with music to determine the
correct output level.

Note: IMPORTANT CONSIDERATION FOR LOCATING THE IS4 C ON WALLS
For wall installations, locate the bottom of the Invisible Series Speaker at least 7 ft. (2.1m) up from
the floor. Placing the speaker lower on the wall will put it at risk for having picture nails or other
hanging devices driven through the diaphragm and damaging the speaker. Since the final surface finish
enables the speaker to completely disappear, it is critical to locate the speaker high enough on the
wall to protect it for the future. Resulting damage of this type is not covered by the warranty.

TEST THE SPEAKER FOR 60 SECONDS WITH
AN AUDIO SOURCE BEFORE COVERING WITH
DRYWALL COMPOUND!
This is the last point any wiring corrections can
be made. After test is complete finish securing with
remaining drywall screws.

EXISITNG CONSTRUCTION
1. Determine the location for the speaker.
2. Using a stud finder, locate the first studs/joists to
the right and left of the speaker position.
3. Mark the centers of the studs/joists.
(See Figure 4, below.)
4. Using the speaker as a template, determine the desired
speaker location on the wall. Mark the speaker’s top
and bottom edges on the drywall. (See Figure 4, above.)
5. Before proceeding, perform an obstruction survey
to be certain that there are no studs, conduit, pipes,
heating ducts, pocket doors, or air returns in the wall
cavity that will interfere with the speaker.
6. Using a drywall saw, cut the drywall along the top
and bottom horizontal marks UP TO THE INSIDE
EDGES OF THE LEFT AND RIGHT STUDS/JOISTS.
(See Figure 5 below.)
7. Using a utility knife, cut the drywall along the vertical
marks at the centers of the studs/ joists. Use the
utility knife to complete the horizontal cuts at each
stud/joist. (See Figure 5, below.) Remove the drywall
from the opening.
• This should expose only ¾” (19mm) of each stud/
joist or half of the stud/joist surface. (See Figure 6.)
8. Test-fit the speaker into the opening, verifying that
all of the speaker’s edges are even with the drywall
edges. If necessary, trim the edges of the drywall to
properly accommodate the speaker.
