In the aspect of controlling the sound quality amplification of the signal, it can raise the sound and the bottom noise is small, and the dynamic range will not produce the sonic boom. The output volume is controlled by the sensitivity adjusting knob. The output part of the headphone hole at the front end of the product can drive 16Ω-600 Ωheadset. The sound quality is without loss and distortion. The circuit part of the product adopts OP + BUG structure and uses AC AC9V transformer to supply power to ensure full thrust, sound fullness, bass calm, high frequency clarity. Input impedance: 100K Ohm Maximum input level: 14 dBV Output impedance: 47 Ohm per output channel Frequency response: 20 Hz -20K Hz Signal to noise ratio: > 107dB Total harmonic distortion: < 0.08% Intermodulation distortion: < 0.01% Input port: stereo 3.5mm jack and RCA Output port: input port: stereo 3.5mm jack and RCA Product power supply: AC9V
