(1) Pay attention to observing the RF signal indicator lights
during the performance to prevent external wireless signal
interference.
(2) When handing over microphone sensors, avoid stacking
multiple open microphone sensors and keep them away from the
receiving antenna to avoid intermodulation interference and
affect the use of microphone sensors.
(3) If there is noise in the sound, it may be due to inadequate
installation of the KTV microphone head, high sensitivity
setting of the microphone head, or interference in the frequency
of use. The main reasons are as follows: there are interference
sources on site (such as mobile phones, walkie talkies, cordless
phones, etc.). In this case, you can try a set of frequencies.
When changing to a new frequency, you can first change the
frequency of the receiving device. After discovering that the RF
signal of the receiving device does not interfere with the
frequency, you can then change the frequency of the transmitting
device. This can detect the cause of microphone sensor noise.
