Specification:
Features:
Advanced digital audio signal processing (DSP) and FM phase-locked loop modulation technique (PLL) ensure less sound distortion and more stable performance.
LCD display is more intuitive and accurate, and has very low power consumption and tiny noise interference.
Built-in 30-class digital volume adjustment can easily complete volume adjustment by pressing buttons.
Automatic storing data when the power is out.
Automatic switching from multichannel audio inputs.
Using quartz crystal for frequency stabilization, and emission frequency will not drift when temperature changes.
Support serial port command control.

Wiring:
Instruction:
4, If you need this module MIC as a source of sound emission, simply unplug the USB and LINE, and module automatically switches to MIC channel as the source of FM. This module with high sensitivity electret microphone can be applied in the wireless microphone as needs.Adjust the emitting volume to achieve the best effect of sound pickup.
User Settings:
1, Backlight Setting:
Press and hold "FRE+" "FRE-" together then power on to set backlight, and if module displays "B1", backlight will be turned on always; if it displays "B0", backlight will be turned on for 20 seconds then off. Restart module to enable setting(default "B0").
2, Open/Close Campus Broadcast:
Press and hold "VOL+, VOL-" together then power on to set campus broadcast, and if module displays "C1", campus broadcast will be open,; if it displays "C0", campus broadcast will be close. Restart module to enable setting(default "C0").
3, Stereo/Single Channel Launch Mode Setting:
There are 2 solder joints "M" and "G" on the back of modules. Connecting these 2 joints leads to single channel launch mode while disconnecting 2 joints leads to stereo launch mode(default "stereo"). Note that the input audio source and radio must also be stereo, otherwise it can not have stereo effect.
Note:
2, Do NOT touch the back of the module components when it is working, otherwise it will probably not work normally or burn out from a short circuit.
