Hi, I am playing with 10 Line 6 XD-V75. I have 7 of them who are linked to the XD-AD8 Antenna Distribution Unit. I have a play called Coup Fatal a play with 14 Congolese it is a play with 6 likembes (this are small hand guitar with a jack input and so I have jacks on my line 6 and 1 mic for a balafon.) I have placed my antennas on the stage right and placed them 5 m of each other to try to have to whole stage. But I still have some drops at some points. Is it maybe better to place them stage left and stage right because they walk around on whole the stage. I also have 3 line6 on stage with the amps of the bass and guitar players what is the best way to place the antennas? And you are talking about the RF1 and RF2 but I can't find it how can you change it? Thanks in advance, Max
