How to Connect:

Before use, ensure that all volume controls are set to the minimum. Then, connect the signal cable and the power supply.

For low-resistance headphones with 16Ω, 22Ω, 32Ω, please adjust the volume appropriately. If the single output volume exceeds 150 mW, it may lead to distortion and a decrease in sound quality, resulting in unclear audio.

The input audio plug must be a three-segment stereo connector.

The input cable does not support 4-connector lines with a microphone function. Using a 4-plug signal cable for input may result in abnormal voice.

The amplifier does not support 2-plug input cables, which may lead to one-sided or no audio output.

Remember to turn off the volume for any unused outputs to avoid unexpected noise or interference.
