Thanks JonG for the reply, sorry for my ignorance in the electrical field, actually I'm not an expert in electronics but in audio so I was asking for advice for this.
For years I have always and only powered the recorder since the Sennheiser G3s run on AA batteries but now switching to the Wisycom MCR54 system with MTP60 I also need to power the receiver.
So from what you confirm there is no problem connecting the Wisycom MCR54 together with the recorder in a single V Mount and I don't risk ruining them because I have seen that many use power distributors which perhaps offer more safety or only serve to have more connections like a splitter?
