UHF-5200 tips: using directional wireless microphone concert, to pay attention to take the microphone position, since the distance between the microphone and the mouth of the distance, the sound quality will be quite obvious changes and sensitivity, particularly because the sensitivity of the microphone and the distance of the mouth inversely proportional to the square, so the sound of jets force inadequate performances, but can not take the microphone too far away from the mouth, the volume of open big megaphone again KTV stage microphone, so it is easy to lead to acoustic feedback; loud throat singer, do not take the microphone by mouth too close, it will easily lead to saturation distortion amplifiers transition UWH-PG4K tips: the microphone and preamplifier microphone KTV entertainment applications, "impedance (Impedance Matching)" is a widely misunderstood topic exists. Because in fact, the vast majority of microphones and microphone preamplifier vast majority, are able to form a more satisfactory combination with each other, do not need the so-called "real" impedance matching. As for the proposed "impedance matching" problem, only in aggressively pursue a particular sound, tone, coloring (coloration) and features will become meaningful.
