Dual Channel Amplifier Amplifier AP-20 For Live Sound Card Speaker

The input end is designed with a balanced circuit, which can be single-ended input or balanced input. Single-ended input uses a large two-core mono plug, and balanced input uses a large three-core two-channel plug. Balanced can be used for long-distance transmission, and balanced for short-distance transmission. It doesn't matter, if you don't understand these just ignore them, professionals can understand them.

The output port is unbalanced single-ended and can use a 6.5mm large two-pin plug;

6.5mm, some people call it 6.35mm, and abroad it is called 1/4 inch;

Independent dual-channel amplification, independent gain adjustment (0-20DB), the two channels can be used alone or at the same time without affecting each other;

Working frequency: 20HZ-20KHZ

Input impedance: single-ended 10K, balanced 20K

output impedance: 200 ohms

Working voltage: DC 5V-12V

static power consumption: 0.3W
