1 In 4 Out: This stereo splitter box allows for one input and four simultaneous outputs, each of which can be independently controlled. You can easily switch each output on or off, and the volume knob can be turned to the minimum to close the output, providing you with flexible control over your audio distribution. High Restoration: Designed with a separate circuit and independent chip, this splitter box offers highly amplified restoration output. It effectively addresses issues such as insufficient output line and sound conversion noise, ensuring that your audio is delivered with clarity and precision. Low Distortion: Achieve ultra-low distortion with this 1 in 4 out stereo splitter, boasting a distortion rate of just 0.0038. This means that if the input is 100, each of the four outputs will be 99.62, maintaining a consistent waveform between input and output for pristine sound quality. Anti Interference: The splitter handles one input for left and right channel signals and outputs them to four channels with independent isolation. This design eliminates interference, noise, and crosstalk, ensuring that your audio remains clear and uninterrupted. Stable Performance: Featuring an active servo power supply system with small internal resistance, this splitter provides stable output voltage and low noise. It effectively ensures the stable operation of the splitter, preserving the high-frequency characteristics of your audio equipment.
