Product Overview
The Fosi Audio BT30D 2.1CH Bluetooth Amplifier combines sleek, freestanding construction with high‑performance audio technology. Housed in a sturdy 5.2 × 4.72 × 1.38 inch aluminum‑coated chassis, the unit measures just 1.38 inches in height, making it ideal for placement on a bookshelf, TV stand, or desktop. Powered by a 24 V DC supply, the amp delivers up to 50 watts of continuous power across its two stereo channels and a dedicated subwoofer output, ensuring deep bass and clear mids for movies, music, and gaming. The core of the system is two Texas Instruments TPA3116D2 digital‑class‑D chips, renowned for their efficiency, low distortion, and thermal protection. Bluetooth 5.0 connectivity provides a stable link up to 50 feet, while traditional RCA inputs give you flexibility for wired sources. The product meets FCC standards and carries the Fosi Audio brand reputation for reliable, affordable audio solutions.
Usage
Designed for the modern home audio enthusiast, the BT30D fits seamlessly into living rooms, home theaters, and bedroom setups. Pair it with passive bookshelf or floor‑standing speakers to create a full‑range stereo system, or connect a powered subwoofer for a true 2.1 experience. Its compact footprint means it can sit beside a TV for enhanced movie sound, on a desk for gaming rigs, or on a kitchen counter for background music while cooking. The Bluetooth 5.0 module works with smartphones, tablets, and laptops, allowing wireless streaming from popular apps such as Spotify, Apple Music, and Tidal. For audiophiles who prefer wired connections, the RCA inputs accept line‑level signals from turntables, CD players, or TV audio outputs. The amp’s 230 V voltage rating ensures compatibility with standard household outlets worldwide.
