SECURING THE TCQ SPEAKER
(U.S. & CANADA ONLY)
To comply with Building Codes, the TCQ MUST be secured to the building
structure with two safety wires.
1. Locate the 20ft length of safety wire. The safety wire needs to be permanently
attached to the solid building structure with metal clips, tie point studs, concrete
anchors or eye screws designed for the specific structure material. The specific
anchors will need to be provided by the installer.
2. Cut the safety wire in half, leaving two 10ft pieces.
3. Install the appropriate anchor into the building structure (see figure 6).
4. Loop one end of the safety wire through the anchor (or eye screw), then twist it
around itself at least five times. Repeat for the second anchor tie point.
5. Place the TCQ into the desired grid location.
Caution: Make sure the TCQ is stable on the grid rails with side brackets capturing
the T-bar grid. If not stable, there could be a danger of it falling until safety wires
are attached.
6. Loop the other end of the safety wire through one of the tabs on the TCQ (located
in opposite corners). Pull the wire through until it is taut and twist it around itself
at least five times to secure the TCQ and cut off any excess wire if needed (see
figure 7).
7. Repeat with securing the second safety wire to the other tab.

SECURE TO CEILING GRID
(U.S. & CANADA ONLY)
1. Locate the four (4) self-drilling sheet metal screws.
2. Utilizing existing holes on the vertical section of the ceiling rail
(center of the hole to the base of the rail must be a minimum
of 0.6", drill two screws on each 2' side of the TCQ (see figure
8). Drilling these screws into the designated areas of the TCQ
chassis will not cause harm to the product.
NOTE: Do not drill in the area designated with yellow tape as
this could affect audio quality and void the warranty.
CONNECT SPEAKER WIRES
1. Find and open the front panel door on the TCQ by sliding the
door toward the end of the TCQ to disengage the lock (see
figure 9A).
2. Run speaker wire through back of speaker and into the
terminal block area. Use appropriate conduit connector or
cable bushing/grommet (not supplied) as needed for the 1/2"
opening (see figure 10).
3. Attach the two wires to the terminal block screws as indicated
(see figure 11). Spade lugs are provided that can be attached
to the speaker wire, if desired.
4. Close speaker door securly by applying pressure outward on
the main body of the TCQ. Then slide the door toward the
middle of the unit and lock into place (see figure 9B).
5. To continue with installation, go to Page22: Connecting Wire
to Amplifier.
