The UNI-PDSB-AUD combines the universal PDS-PLUS mount with a universal short-throw projector wall mount and powerful stereo audio system. It extends 7 - 27 in. from the wall or up to 67 in. when used with an optional arm extension. It does not require a stud located in the center of the whiteboard or screen and mounts to dual studs at 16, 18 or 24 in. spacing. The included Compact Power Amplifier, CPA-50, powers the speakers and supports multiple stereo inputs for connecting to a projector, microphone and other sound sources.
