Hi
@ Accordeon49
with each microphone is provided a receiver so, as well shown by Guigni, 2 microphones and 2 receivers in total (MG and MD)
the receivers are connected to an amplifier
in case of use abroad, the question of authorized frequencies must be asked, as these microphones are available in several versions (600 MHz- 740 MHz- 863 MHz) the 863 MHz version, authorized in the whole of Europe, seems to be the right choice
in case of use in an orchestra, it is necessary to take care to make the adjustments so as not to make the frequencies "overlap" (rare and in this precise case 16 frequencies are available, no problem except for your next performance with André Rieu)
good music to all
