Product introduction:
- 88-108MHZ full band step 0.1MHZ adjustable
- Volume digital and analog dual adjustment
- Digital linear adjustment of power 0.1W-0.5W(1W)
- Timing on and off RF signal (select function)
- High-definition sound quality: S / N signal-to-noise ratio:> 75db modulation distortion: <0.3%
Structure description：
Instructions：
- Up and down keys can step 0.1MHZ to increase or decrease the transmission frequency
- Press the M menu key to switch to different functions, adjusted by the up and down keys.
- For transmission power adjustment, 1% is about 0.1W minimum, 100% is the maximum power of the machine
- The microphone and audio interfaces are standard 3.5MM stereo interfaces
- Only the timed version can adjust the time and the year, month, day, and week
- The antenna interface is BNC. When the transmission power is greater than 5W, please use a 50Ω antenna with good performance, otherwise, it will produce noise and even damage the transmitter.
- Timed version(optional): Please contact the seller to request the computer timed software. When the USB data cable is connected to the computer, it does not need to be connected to the power supply. When the timing is set, there is no need to connect to the computer. The timing program is automatically stored in the machine.
