Attention:
The board is noise-free. When auditioning, please plug your audio device into the audio input of the board. Please do not leave it empty, because if it is empty, the signal line will introduce noise, and the shielded line will not work when it is not connected to the audio source device. Shielded cables are required for connecting the audio source to the amplifier. In addition, it is recommended to ground the potentiometer and the case when installing a case.
