Details

The advantages of ZK-MT21S compared to ZK-MT21: 1. Added U disk/sound card interface
2. Added encoder for up and down song selection, for pause/play, for AUX/BT/USB audio source switching selection
3. The mid-range adjustment of the stereo part has been added, and combined with the subwoofer + treble to form a full coverage of the low, medium and high sound effects range, compared to the MT21, the increased translucent vocals are prominent.
4. Compared with MT21, the APP function is added. The APP supports changing the bluetooth name, password, prompt tone size, prompt tone switch, sleep aid song, mode switch, sound effect selection, U disk list, etc.
5. The frequency adjustment of the subwoofer is changed to the internal debugging of the board. After debugging, the customer will not change it at will, effectively protecting the speaker and power amplifier.

6. Remove the stereo bass adjustment (many customers feedback that the stereo bass is unnecessary, because it is repeated with the subwoofer), and change it to the midrange to make the sound more transparent.
