Product description:1. If you have a line level signal source (TV audio, MP3 player, video game machine, cell phone, tablet, computer, record player, etc.) to output to other devices at the same time (such as power amplifier and speakers or headphones), this product can solve the problem of one set of stereo input, which can allocate four sets of stereo, output independent four sets of volume adjustment function, with each channel output band + 20dB gain.2. For a powerful signal amplifier distributor, you may need to run several long lines between the TV audio line and a receiver on the other side of the room, providing high gain through any line level signal source, allowing longer cable lines to run, or requiring "buffering" to solve low volume problem. You can use it to add signal amplifiers between the line level signal source and the power amplifier, and the RCA jack matches almost all other product interfaces.3. This product can increase the sound quality of the control signal and reduce the bottom noise. With a large dynamic range, it will not produce a burst. The output volume is controlled by sensitivity adjustment knob, and DC 12V power supply is adopted to ensure full thrust.Product parameters:1. Input impedance: 100K Ohm2. Input level: +14 dBV3. Output impedance: 47 Ohm per output channel4. Frequency response: 20 Hz-20K Hz5. SNR: Less than 107dB6. Total harmonic distortion: Above 0.02%7. Intermodulation distortion: Above 0.01%8.
