Installation Considerations - Proficient Audio Systems MDS Owner's Manual

INSTALLATION CONSIDERATIONS

NOTE: It is very important to note that when using the Pre-Construction Bracket, the MDS Back Plate must be installed before the drywall
is finished. In a J-Box installation, the MDS Back Plate can be installed after the drywall is finished. MDS Series Speakers cannot be properly
installed without the MDS Back Plate. The MDS Back Plate must be secured to a standard metal single-gang J-Box or the PCB-MDS
Pre-Construction Bracket. NEVER MOUNT DIRECTLY ONTO DRYWALL!
Prior to the actual installation of the speakers, it will be necessary to pull wire to the speaker locations. We recommend that at least 16/2
stranded wire be used. After the wires have been pulled, you are ready to mount the speakers.
SPEAKER WIRING AND MOUNTING
J-Box Installation
When installing MDS Series Speakers on a J-Box mount, secure the J-Box to a wall stud or ceiling joist as shown in Diagram 2. If installing the
MDS Back Plate before the drywall is installed, attach the MDS Back Plate with the flat side toward the J-Box. Position the J-Box so the front
wide surface of the MDS Back Plate (not the opening) will be flush with the back of the drywall when finished to prevent bowing the drywall.
(Approx 1/16" back from the edge of the joist/stud.) See Diagram 2 Complete installation starting with Step 4 . If installing the MDS Back Plate
after the drywall is installed, attach the MDS Back Plate with the flat side away from the J-Box. Position the J-Box so it will be flush with the
back of the drywall when finished to prevent bowing the drywall. (Even with the edge of the joist/stud.) Complete installation starting with
Step 4 .
Pre-Construction Bracket Installation
For ceiling mount or wall mount situations when the joists or studs are not where the J-Box needs to be, use the PCB-MDS Pre-Construction
Bracket (purchased separately) to position the MDS Back Plate to the desired location.
Step 1 Position the bracket in the desired location and spread the bracket to fit the space. See Diagram 3
Step 2 Secure the bracket using the included wood screws. Position the bracket so the wide flat surface of the MDS Back Plate (not the
opening) will be flush with the back of the drywall when finished to prevent bowing the drywall. (Approx 1/16" back from the edge of the joist/
stud.) See Diagram 3
Step 3 Slide the MDS Back Plate to the desired position. Firmly tighten to the PCB-MDS Pre-Construction Bracket. Do not over-tighten. See
Diagram 4
Step 4 After the drywall has been installed (Diagram 5), if not already accessible, fish the speaker wire through the exposed part of the MDS
Back Plate. See Diagram 6
Step 5 Pull the speaker wire through the wide opening in the Beauty Plate and attach the Beauty Plate to the MDS Back Plate using the
included screws. See Diagram 7
