Fosi Audio BT20A Bluetooth 5.0 Stereo Audio 2 Channel Amplifier Receiver Mini Hi-Fi Class D Integrated Amp 2.0 CH for Home Speakers 100W x 2 with Bass and Treble Control TPA3116 (with Power Supply)

Overview

The Fosi Audio BT20A is a compact Class D integrated amplifier built for Indian homes that want clean, powerful stereo sound without the bulk of traditional receivers. It ships with a 24 V / 4.5 A power supply and runs on standard 230 V mains, so you can plug it in straight away — no voltage converter needed. At just 13.2 × 9 × 3.6 cm and 680 g, it fits neatly on a bookshelf or desk while driving passive bookshelf or floor-standing speakers up to 320 W (4 Ω) or 280 W (8 Ω). Bluetooth 5.0 gives you a stable wireless link up to 50 ft with no audible pop when pairing, and the Texas Instruments TPA3116D2 chips keep THD down to 0.04 % across 20 Hz–20 kHz. Backed by a 24-month warranty and responsive email support, it’s a practical step-up from basic TV or phone audio.
