A VHF "discrete" non-diversity receiver the WR22-PRO allows you to use
two wireless microphones simultaneously. Unlike the WDR-PRO each
receiver inside the case is set to a different frequency allowing you
to record the sound from 2 microphones at the same time. On-board
controls allow you the videographer to monitor the signals being
received and to stop receiving from either microphone if you wish.
Receives on both standard "PRO" frequencies (169.445MHz and 170.245Mhz).
