Mounting and Cabling Options
You can mount the soundbar horizontally or vertically, with the Ethernet cable routed through the wall (directly behind the bracket) or
through the bracket’s Cable Pass Notch. For ease of access when releasing the speaker from the bracket in the horizontal position, it is
recommended to position the bracket with the Release Latches (Figure 6) on the bottom.
NOTE: If you are not feeding the cable through the wall and bracket, position the Cable Pass Notch toward the display, as
shown in Figure 7. In this case, orient a horizontally-positioned bracket with the Release Latches on top.
— Figure 7 —

Connect the Cable
Before mounting the speakerbar, plug the Ethernet cable’s RJ45
connector securely into the jack on the back of the enclosure (Figure
11).
Attach the Soundbar

the soundar will snap and lock onto the wall bracket (Figure 12).
Align the Soundbar – Horizontal
You can adjust the soundbar left or right as needed to align with the display, cameras, or other wall-mounted objects.
1. Review the soundbar’s alignment with other objects (Figure 13).
2. Release the soundbar from the wall bracket. See “Release the Soundbar”.
3. Re-attach the soundbar in the desired position.
NOTE: Sliding the soundbar while it is locked to the bracket is not recommended.
