Instructions:

Be sure to use batteries with a 3.7V overcurrent rating of 5A or higher and a protective board. Otherwise, the maximum volume battery will protect it. The volume cannot exceed 50% when using 5V3A power supply without battery and wired power supply, otherwise it will restart. It is compatible with 4Q speakers (2Q speakers cannot be used)

The signal-to-noise ratio of the amplifier is 67, which means that when the volume is very low, white noise can be heard at a distance of about ten centimeters from the speaker. Remember not to shoot if you mind.

The tuning software does not support Win7 and below systems, supports 30 5V RGB expansion, hides volume adjustment pads, can charge batteries, and is powered by a single power battery; Support computer tuning to save EQ, 10 segment EQ gain with DRC dynamic compression.
