Stereo Sound Signal Mixer Board Module 2 Channel Input 1 Channel Output Headphone Amplifier Board

Feature: 1. 2 IN 1 OUT: Stereo sound signal mixer board module mixes stereo two way sound inputs into one stereo output, which can directly drive headphones or power amplifiers. 2. AMPLIFIER: Stereo sound signal mixer board module uses the NJM3414 low voltage, high current operational amplifier. The power supply is DC 5‑12V, and the amplification is about 2 times. 3. 3.5MM INTERFACE: Sound signal mixing board module has a 3.5mm headphone interface, which can directly drive headphones or connect to an amplifier. Potentiometers control the volume of each channel separately and do not affect each other. 4. CURRENT: The quiescent current is about 8ma, and the maximum drive current is 70ma, which can easily drive various headphones and external amplifiers. 5. USE NOTE: Stereo sound mixing board module is easy to use, please use low ripple power supply, sound cable please use shielded wire.
