Infrared frequency 1 trailer 4 meeting
The machine features
1: Use UHF600 to 870MHz frequency band, strong anti-interference .
2: PLL with high precision quartz crystal , plus microcomputer chip
control , high frequency stability.
3 : with infrared frequency ( synchronous ) function , improving
the product's ease of use.
4 : pilot with advanced digital features, the complete elimination
of interference and frequency channeling phenomenon .
5: with automatic mute and the impact of the three-way relationship
between the elimination and logic circuits , switch machines to
avoid shocks and noise.
6 : with automatic selection function , quickly and accurately
identify the available channels without interfering greatly
simplifies project installation and commissioning work .
7 : with adjustable transmit power and adjustable squelch threshold
, both of which easily can be effectively controlled with the use
of distance.
8 : double boosting circuit design , when the battery voltage is
reduced without affecting the emission performance.
9: simple interface , very few adjustable parts , completely avoid
misuse can cause malfunction .
10: The first use of the conference microphone mute switch ,
effectively prevent mechanical noise switch machines.
11: pickup high sensitivity, excellent sound quality , so you can
speak or sing with ease .
12: Multiple stack machine can be used without interference and
frequency channeling phenomenon .
