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. |
