Microphone maintenance tips
microphone is a very important multi-media classroom an integral part of, although it uses a simple, relatively cheap prices, but the decisive role. Multimedia devices, the microphone is the device most frequently used one, if used improperly, would greatly reduce the life span, affect the normal use of multimedia classrooms. The maintenance of common sense to note the following:
1. Proper cable installation and removal and microphone. The XLR plug (commonly known as XLR head) into the microphone, rotate the plug so that the above deduction key notch aligned with the microphone, then plug into the microphones, until the button key location; microphone cable separately, they can hold plugs, press button while holding down the button, and then pull the plug fr
om the microphone. Do not press the pressure button is not aligned or key to access the case of forced and separate operations. 2. Microphone in use a “howling”, may be due to hand covering the microphone or the microphone too close to the head caused by loudspeakers, the correct solution is: First of all, lower the volume, beginning with the amplifiers distance from the microphone and loudspeaker to avoid the relative, and then adjusted to the appropriate volume.
3. Microphone is a high sensitivity of audio equipment, must pay attention to light up light to take to TradeTang.com avoid falls from PC Remote Controls . Impact may result in reduced or even damage the microphone sensitivity.
4. Do not blow on the microphone or hand flapping hard in the head to an audition, audition is the right microphone speaking in normal tones.
5. On the microphone, the key to open the sliding pay attention to moderate intensity, the push and pull in place. If you found a Travel Luggage use of noise, may be due to the open key is not in place or pull caused by bad contacts, the correct approach is to re-push switch. If access is not good, should be repaired promptly.
6. Conference microphone or wireless microphone with a long-term need, it should remove the battery, to be used to install. In the course of the case if there is intermittent sound, may be due to lack of battery power due to battery replacement time.
7. Not when the microphone kept in a clean dry place, avoid temperature, humidity, storage and use of high places, so as not to affect the sensitivity of the microphone and sound.
8. Be used to solve multi-channel and avoid interference, the digital lock should be used to change the frequency of multi-channel series models: the conventional wireless microphone system is the use of quartz locked fixed frequency design, this model requires a multi-channel use in the occasion or event to strong signal interference, it is not any change you want to use the frequency, but must replace the entire units. To address this deficiency, advanced models will use the phase locked frequency synthesizer (PLLSynthesized) means within the receiver stored in the launch dozens of arbitrary frequency allows users to transform, although the high cost of such advanced design However, users on the distribution and provide a very convenient feature, the lack of resolve. Taiwan companies have MIPRO this design the most advanced energy production, rationalization of the price the most complete line of products.
