Multi-function FM FM Stereo Transmitter Module / Microphone Wireless Transmitter / Wireless Microphone Module
First, the product features:
1: Use advanced digital audio signal processing (DSP) and FM phase-locked loop modulation (PLL) to make the sound more realistic, more stable performance, and no shift in long-term operating frequency.
2: LCD display is more intuitive and accurate, with very low power consumption and minimal noise interference.
3: Built-in 30-level digital volume adjustment, easy to complete by button operation.
4: Data after power failure automatic memory power failure
5: Multi-channel audio input is automatically switched
6: Using quartz crystal to stabilize the frequency, the temperature changes the transmission frequency and no longer drifts.
7: Support serial command control
