    Description

    1. Professional Multi-Channel Audio Distribution

    The Fosi Audio PH05 is a high-performance 5-channel headphone amplifier designed to deliver pristine, high-fidelity audio to multiple listeners simultaneously. Whether you are managing a professional podcast, a studio recording session, or a shared home entertainment setup, the PH05 ensures each listener experiences consistent, crystal-clear sound without interference.

    2. Key Features & Technologies

    Precision Independent Volume Management

    • Five Dedicated Channels: Each of the 5 output channels features its own independent volume control knob, allowing every user to tailor their listening levels without affecting the others.

    • Master Control & Mute: Equipped with a centralized Master Volume dial for global adjustments and a one-touch Mute button, providing instant control over the entire audio feed—essential for rapid studio transitions.

    High-Fidelity Audio Performance

    • Exceptional Driving Power: With a maximum output of 310mW @ 32Ω per channel, the PH05 can easily drive a wide range of headphones from 16Ω to 300Ω, maintaining a rich and dynamic response across all loads.

    • Low Noise & Low Distortion: Featuring a high Signal-to-Noise Ratio (SNR ≥ 105dB) and ultra-low THD+N (0.001%), it provides a studio-grade "black" background, ensuring no hiss or hum distracts from the performance.

    Robust Design & Connectivity

    • Premium All-Aluminum Build: The CNC-machined aluminum alloy chassis offers more than just a premium look; it provides superior heat dissipation and shields the internal components from electromagnetic interference (EMI).

    • Universal 3.5mm Interface: Features a standard 3.5mm AUX input and five 3.5mm headphone outputs, ensuring seamless compatibility with smartphones, laptops, audio interfaces, and professional studio monitors.

      How to Diagnose Power Supply Failure?
      • The following situations may cause this issue

        Test the adapter with a meter.

        Try a different power supply (within a range of DC input).

        Test the included power supply on other electrical equipment.
