No, unfortunately this is not possible. The two radio frequencies used are fixed to ISM2 (864.375 MHz) and ISM3 (864.850 MHz). Operating the same thing again therefore interferes with each other.
We use the microphone in a room of about 100 m2 . The receiver is in the back of the room and we always have clear reception in the whole area. The distances are on average 8 - 12m between the receiver and the handheld microphone.
From time to time, the first announcements also start from the entrance cloakroom or an adjoining room, which have worked perfectly so far.
A good device at a reasonable price.
