Performance and Detail
The 32 RGB LEDs are evenly distributed across the 182 mm length and can display multiple colours simultaneously, recreating the classic VU meter effect — a column of light that rises and falls with the intensity of the sound. The 32-bit ARM processor processes audio signals in real-time, updating the display every 0.08 seconds. The integrated microphone with active noise filtering separates relevant sound sources from electrical interference, ensuring the bar responds to your music, not static.

Frequently Asked Questions
Does the LED bar react to any sound or just music?
It reacts to any sound captured by the microphone — music, voice, or applause. Active filtering reduces electrical interference, but the bar will respond to any sufficiently loud sound source nearby.
Can it be used without sound activation, in static mode?
Yes. By cycling through the modes with the MOD/SPEED button, you can select static effects or animations that are independent of sound — ideal for continuous ambient decor.
How long does the battery last and how long does it take to charge?
Battery life varies depending on brightness and the selected mode — typically several hours of active use. A full charge via USB-C takes approximately 1-2 hours.
Can multiple bars be used together for a larger effect?
Yes. Each bar operates independently, so you can purchase multiple units and arrange them in any configuration you like for a greater visual impact.
Can the USB-C port be used to connect to a PC or just for charging?
It is for charging only. Any standard 5V USB-C cable or adapter will work — no dedicated charger is required.
