FiiO A1 Mini 2x14W Class-D Digital Audio Amplifier

  • The FiiO A1 is an advanced compact desktop stereo amplifier designed to provide high fidelity amplification for playback on small bookshelf speakers or unpowered monitors. It combines both a preamp and power amp in the same chassis, able to take input directly from a line-level source.

    Feature Highlights
    - High performance TI OPA2134 audio operational amplifier for preamp circuitry With low noise, low distortion and high conversion rate.
    - NXP high efficiency Class D TFA9815T power amplifier with BTL output for low voltage and high current capability.
    - Each of the two sound channels use a different carrier frequency (550KHz / 600KHz) to achieve high fidelity conversion and minimized mutual interference.
    - "0" dead zone design and protection against overheating, over-current, over-voltage, undervoltage, including detection protection on power up.
    - Differential input level combined with adjustable negative feedback circuit ensures low noise, low interference and low distortion
    - On/off mute function
    - Closed APLS potentiometer ensures low noise and good channel balance
    - RCA and 3.5mm two audio input, for flexible connections
    - Minimum output 4 ohm adaptive impedance
    - Banana plug/terminal output
