The interpretation will encounter problems such as the microphone will be intermittent when the radio frequency signal (RF) is full, the noise will be generated after the transmitter is turned off, and the transmitter and connector frequencies are adjusted to match the sound. The following is the detailed answer for you.
Why is my microphone intermittent when the RF signal is full?
Why does it cause a lot of noise when the transmitter is turned off?
Why is there still no sound in my transmitter and connector frequency?
These problems are often asked by some users, and even some of them are considered to be faulty and returned directly to our repair center, especially in the first generation of the revolutionary series. Here I elaborate on the squelch value of the wireless microphone receiver (SQUELCH). The first generation and the G2 EW100 are only abbreviated as SQELCH due to the limitations of the display. Some places are abbreviated as SQ for convenience.
Squelch value: It uses a threshold circuit to squelch. When the signal level reaches the intensity, the door is opened. When the signal level is lower than this value, the door is closed, and the noise intensity and squelch value in the received signal are Inverse relationship. Setting the squelch value too high may not receive a useful weak signal, and too low may be disturbed by noise and other unwanted signals. The higher the noise, the weaker the noise; the lower the noise, the stronger the noise. In the Sennheiser revolutionary series, the squelch value is set from 0dB to 40dB. The higher the number, the higher the level, indicating that the squelch suppression is stronger, and the less interference is caused by noise or other unrelated signals, but the more difficult it is to receive the signal that needs to receive the transmitter. Conversely, the smaller the number, the lower the level, the weaker the suppression of squelch, the greater the interference from noise and other unwanted signals, and the easier it is to receive the weak signal from the transmitter. If the receiver is adjusted to 0dB, it means that there is no squelch suppression function, the receiving distance can reach the farthest distance, but when the transmitter is turned off, a lot of noise and other unwanted signals will directly enter the receiver, and the tuning will be transmitted. station. Many users accidentally press the squelch value to this position, which causes background noise. When the user adjusts the receiver squelch value to 40dB, the squelch level reaches the highest level, and when the emission level strength does not reach the squelch threshold, there will be no sound or the sound will be intermittent. Therefore, these two limits are recommended for users not to set.
The second generation of the revolution is to avoid user misdesign. There are only three files in the design: low, mid, hig, which reduces the user's improper operation in the process. It brings convenience to the user. Of course, the natural enemies of wireless microphones are subject to interference. I will continue to analyze some of the problems that need to be paid attention to when using G2, or when users encounter problems with wireless microphones, we can discuss them together. I am in "Getting Close to Professional Wireless Microphones". There are also some questions involved in the post, but it was written at the time.
