A:AnswerThank you for your question. Using two sets of JBL Wireless Microphones would cause interference since our microphones are only dual channel and the dongle will randomly choose a new channel for the microphones each time they are turned on. Even if the mics all show a different channel number, they will likely end up on the same channel which caused the interference. We recommend using a wired microphone.
A:AnswerThanks for your question. Our JBL PartyBox Wireless Microphone Set can connect to one wireless receiver (dongle) at a time, and the dongle typically supports only the two microphones that come with the set.
