RCV is a passive box designed to receive balanced signal from LongLine (sold separately) via its XLR jacks. It can receive a stereo XLR signal from LongLine and convert it to unbalanced 1/4" outputs so you can plug your signal directly into your amp. It is designed to work with a stereo / dual mono signal (sending to two amps) or a mono signal (sending to one amp) and is completely passive (no power required for RCV).
