Details
Extron PLS 401D (part number 42-321-23) — the current 4+2 input PlenumVault Digital classroom system, complete with ceiling projector mounting hardware.
Two wallplate positions instead of one is the practical difference here. A lectern plate and a second plate at a student table or side wall both feed the same PVS 407D switcher over a single shielded twisted pair run each, while two more HDMI inputs on the switcher body stay free for permanently installed devices. The whole electronics package sits inside the PVM 220 enclosure above the ceiling grid, and the projector hangs from the supplied PCM 340 pole with a UPB 125 bracket for aiming.

- Draws 30.4 watts at 12 VDC, or 37.1 watts including the external power supply
