<br> 1. broadcast design should be reasonable, the realization of each piece of equipment to be able to reflect the functional design and flexibility. .<BR> <BR> 2. Matching the power amplifier should be: the actual power = nominal power amplifier * 75%. .<BR> <BR> 3. Horn lines must pay attention to the installation of positive and negative level, and prevent speaker lines are wrong, resulting in the phenomenon of burning power amplifier, causing unnecessary losses. .<BR> <BR> 4. Line installation to eliminate the glitch phenomenon, to prevent short circuit and burn amplifier. .<BR> <BR> 5. Broadcasting in use, plug the microphone when the microphone is sure to turn down the volume switch to plug, so as to avoid impact damage to the amplifier. .<BR> <BR> 6. Broadcast equipment on and off in order to open to closed, remember the easy way to directly turn off the power strip at the turn on the power. .<BR> <BR> 7. Radio volume to be appropriate, not too fast to reverse the volume, including net after-class high-power amplifiers and other equipment, so as not to impact on the equipment. .<BR> 8. Note that the maximum position indicator light amplifier, not long-term work in the distortion of the state. .<BR> <BR> 9. The power is not full timing, increase speaker volume is Cadogan, not unlimited turn the volume knob way up. So as to avoid impact damage to equipment. .<BR> <BR> 10. There can be only one output amplifier, not a few amplifier connected between the output and. .<BR> <BR> 11. Radio device must be connected before power is turned off, turn off the volume before connecting all devices, then completed, by checking correct, only in order to open the device. .<BR> <BR> 12. Each paging paging end points in a certain area, be sure to immediately switch off the paging area, paging area so as not to interfere with other normal paging in the region. .<BR> <BR> 13. Note: The central control unit mains power supply must be direct, and often in a short time is best not to switch the machine control for. .<BR> <BR> 14. In front of paging speakers when the microphone must not place or use high-frequency sound source, in order to avoid generating self-excited high-frequency whistle..
