Extron VLR 302 (part number 60-1637-01) — the wireless receiver at the centre of an Extron VoiceLift Pro classroom voice amplification system.

The VLR 302 does two jobs. It pairs with up to two VLP 302 pendant or VLH 302 handheld microphones, creating an exclusive link that stops a neighbouring classroom's transmitter bleeding into the room. It then hands the audio to a PVS Series switcher down a single RJ-45 run that also carries power and control, which removes a power supply and two more cables from the install. At a quarter of a pound it can be tucked inside a PVM, USFM or WMK enclosure next to the switcher.
