How to use:
1. AC DC 12-16V power supply, need to distinguish between AC and DC input.2. When wiring, L, G, and R correspond to the left, ground, and right channels of the audio source device, respectively. If the input is mobile phone, computer sound card, preamp and other audio sources, please turn DIP switches 1 and 3 to the ON terminal, if the input is the output terminal of the power amplifier, please turn DIP switches 2 and 4 to ON terminal, the will be compressed 11 times.3. The 100R V adjustment potentiometer allows you to adjust the brightness of the VU meter backlight.4. The adjustment potentiometers 50k 1 and 50k 2 control the jump amplitude of the needle of VU meter 1 and VU meter 2
