WPB 103 B and WPB 107B • Quick Start
C Installation and service must be performed by authorized
personnel only. These units must be installed in
accordance with the National Electrical Code and with
local electrical codes.
N These wall plates use pass-through connectors as well as active
audio buffering without signal processing.
To install the WPB wall plates, follow these steps.
Step 1
Select the site and run cables through the wall or furniture where
the wall plate(s) will be installed.
Step 2
Prepare the site.
a) Cut a hole (see page 4 for a template) and install an electrical
box or mud ring/mounting bracket. Cable clamps should be
used to hold the cables in place for strain relief.
b) Trim back and/or insulate exposed cable shields with heat
shrink to reduce the chance of short circuits.
Step 3
Connect the terminated output cables to the wall plate’s rear panel
connectors, captive screw connectors, or BNC pigtails, in the correct
sequence.
• Buffered computer audio input from a 3.5 mm stereo mini plug is
output on a captive screw connector. (See the diagram below).
• Buffered stereo audio input from two RCA connectors is output to
captive screw connectors (WPB 107B only).
(See the diagram below).
