Wireless Microphones Receiver

I am selling a receiver for Power Dynamics PD504 wireless microphones, it does NOT include microphones, what it does include are the 2 antennas of the receiver, transformer and the plates to be able to put it in a rack, the microphones can be purchased loose in any store specialized in professional sound, the Loose microphones are worth 65 euros each, the entire set is around 390 euros in stores like Madrid hifi or professional dj
