HORIZONTAL ORIENTATION INSTALLATION STEPS:
IF INSTALLING IN NEW CONSTRUCTION (PRE-DRYWALL), SKIP STEP 1
1. Cut a 46" wide x 14.5" high (971.6mm x 292.1mm) hole in the drywall. The center of the hole should align
with the center of the video display.
2. Cut completely through the wall studs that fall inside the space needed for the SCL-2 (Figure 16).
MAKE
SURE IN ADVANCE THAT THEY ARE NOT LOAD BEARING STUDS.
3. Use 2x6s to create a frame with 38.25" x 11.5" (971.6mm x 292.1mm) internal dimensions (Figure 17).
Secure to existing studs with nails or woodscrews.
4. Install new drywall up to the edge of the new 2x6 frame (post-drywall installations only). Some spackle and
tape work will be required.
5. Connect the signal wires to the terminals on top of the back box as described on Page 6.
6. Orient the back box so that the input terminals are closest to where you want the horn to be located.
7. Lift the back box into the space defined by the frame.
DO NOT USE THE MOUNTING BARS TO LIFT
THE BACK BOX
; lift the back box by the cabinet braces.
8. Allow the mounting bars to rest on the drywall to establish the proper back box depth. In new construction
installs, tack a piece of scrap drywall on the nearest studs to establish box depth.
9. Use drywall or wood screws to secure the mounting bars to the studs under the drywall. The mounting bars
temporarily hold the back box in position.
10. Install rubber bushings into the left, right and middle mounting holes. Place a metal washer onto each 5"
deck screw and insert the screws through the rubber bushings into the adjoining 2x6 frame. Tighten the
screws enough to expand the isolator mounts (bushings), but do not tighten beyond this point.
11. Make sure the back box is securely attached to the frame and then remove the mounting bars completely.
Discard.
12. Repeat step 8 with the remaining mounting holes.
