Note: Be sure to use a 3.7V battery with a current rating of 5A or higher and a protective board. Otherwise, the battery will trip at maximum volume. When using a 5V3A power supply without batteries, the volume cannot exceed 50% when powered by a wired connection, otherwise it will restart. It is compatible with 4Q speakers (2Q speakers cannot be used). The amplifier's signal-to-noise ratio is 67, which means the volume is very low. You will hear white noise when your ear is about 10 cm from the speaker. Please do not take pictures if this is a concern. The tuning software does not support Windows 7 or earlier. It supports 30 5V RGB expansion, hidden volume increase and decrease pads, battery charging, and single-cell battery power. It supports computer-based tuning and save EQ, 10-band EQ gain, and DRC dynamic compression. label:yes
