| Why adopting the PLL synthesized design? |
| With the quick development of the wireless communication technology, the frequency used today, |
| may be interfered and cannot be used tomorrow.Only with PLL synthesized design to realize the |
| multiple channels design, the machine can normally work continuously. The channel of machine with |
| PLL synthesized design, can be changed easily, fast and correctly. Machine with PLL synthesized |
| design is the better choice and ideal machine. |

| Why use UHF frequency? |
| Nowadays the VHF 200MHz frequency is becoming more and more full, thus the signal .mutual |
| interference and all kinds of machines'noise interference is more and more The problem is becoming |
| more and more serious. Using UHF frequency can avoid the frequency traffic and the signal |
| interference. |

| How to use the lavalier microphone to reach the better sound? |
| When using lavalier microphone to amplify, if the volume is raised randomly, the buzz will easily be |
| produced. This is a hard audio tough. If you want to turn on the volume of the microphone and don't |
| want to cause buzz, the only but one way is to shorten the distance between the microphone and |
| the mouth. Thus you can raise the sound of the microphone without the need to turn up the volume |
| of the amplifier. |
| |
| What¨s the digital pilotone & noise cancel technology? |
| Add a continuously changing UHF signal into the transmitter, and then relatively add a pilotone identifying |
| circuit in the receiver. When the receiver receives the transmitting signals with digital pilotone,the circuit |
| will be on. And the signals without digital pilotone even of the same frequency cannot open the output |
| circuit. This is for noise cancel. |

| Why use IR communication in channel selection? |
| IR communication makes the channel adjustment more convenient and deletes the nconvenience of the |
| i hardware adjustment. Also the number of the channel will not be limited by the hardware. |
| |
| Why use the switching power in AU210 series? |
| Adopting the switching power, the range of the input voltage of the power will be wide (AC85-260V). |
| It will meet the requirements of all the countries and districts. Also it is plug-and-play.When the built-in |
| accumulator battery is short of electricity, it can work long time with full-load. |
