Accusound Wireless system accessories are items that make up the standard systems or are extras. Items such as replacement body pack or handheld, lapel of headset microphones. We can also supply replacment lapel microphones. It should be remembered that only one transmitter can be used with any receiver. If a second transmitter is used on the same frequency at the same time there will be significant interference. If a second transmitter is required then the user MUST ensure that the first transmitter is switched off before the second is switched on.
