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. • Elevate your listening experience with our Ultra Compact 4 Channel Stereo Headphone Amplifier, designed for exceptional sound quality and high-power stereo output with individual volume controls. • Equipped with 4 ports for 3.5mm output and 1 port for 3.5mm input, our amplifier is fully compatible with a wide range of 3.5mm headphones for versatile use. • Enjoy pristine sound quality in both studio and live settings, thanks to our innovative anti-crosstalk design that minimizes interference for a clearer audio experience. • Each channel of our headphone amplifier features its own level control, allowing you to customize your volume settings and reduce unwanted noise for a tailored listening experience. • Powered by a 5V AC adapter and housed in durable aluminum, our amplifier ensures safety and stability while delivering superior sound quality for an exceptional audio journey.
