The Fosi Audio AH-01A is a desktop music visualizer: two glass tubes, each with a 48-LED full-color strip, pulse to the sound its built-in microphone picks up, and it runs on USB 5V/1A power. It suits desk, gaming and hi-fi setups that want a light show without wiring anything into the audio chain.
Who the Fosi Audio AH-01A is for
Desk and gaming setups: Sound pickup runs through the built-in microphone, so nothing has to connect between the light and your PC, console or speakers.
Hi-fi shelves: Fosi Audio styles the anodized aluminum base, clear glass tubes and orange center knob after vintage tube amps.
Custom lighting: Lighting color, sensitivity and fall-off speed are adjustable, and pressing the center knob switches between lighting modes.
Tight spaces: The base measures 83 × 83 × 27 mm and runs on 5V/1A USB power, so it fits beside a monitor or amp.
Skip it if: You want the lights tied to your music signal; there is no line or USB audio input, so it responds to ambient sound reaching its microphone, not to the audio signal itself.
