Humming and buzzing in an audio system is usually caused by ground loop. There could be exception, like the broken circuit or a damaged microphone capsule. But ground loop explains most of the buzzing cases. Ground loop causes buzzing! Having the ground is always the starting point when setting up an audio system. It is essential for safety reason and...
One of the common problems that cause dropouts is antenna placement. The antennas for the wireless system are buried in the back of or under a rack. Then the metal will reflect the wireless signal. Or the receiver is placed in a closet or under a table, where it is not in line of sight with transmitter. It will compromise the signal that receiver can pick...
It can not be denied that wireless system provides great convenience. But just like any other electronics, it is possible to escape from glitch, which is cutout or dropout for a wireless system. What we can do is to help reduce the chances that you will experience a dropout during live. Too many factors will have impact on the performance...
You will feel more like it for setup a wireless system after paying a bit more attention to six things. 1.Power issue Low voltage brings up problem, like cutouts, dropouts or distortion. Lithium-ion batteries outlast Ni-Mh and Ni-Cad ones. Because of up to 20% less voltage output, rechargeable battery is far from ideal option as it seems to be. So if budget allows, one-time use...
First off, we will walk through the differences between all three input that you can normally find on a mixer or speaker. What differs them is the signal intensity, so-called signal level. There are basically four types of signal level. The microphone signal has the weakest voltage, typically just a few ten-thousandths of a volt. But it will vary slightly when the...
