The Fosi Audio DA2120C is a sophisticated 2.1-channel amplifier integrating a high-performance DAC and delivering 120W per channel at 4Ω through Texas Instruments' TAS5352A chipset. This dual-function device combines digital-to-analog conversion with Class D amplification, eliminating the need for separate components while maintaining exceptional audio fidelity. Bluetooth 5.0 with extended 65-foot range via 6dBi antenna ensures stable wireless connectivity, while comprehensive input options—RCA, USB, coaxial, and optical—accommodate virtually any audio source. The bright LED display and included remote grant intuitive control over input selection, volume, and independent EQ adjustments. Built-in protection circuitry safeguards against fault conditions, while the robust 32V/5A power supply efficiently drives passive speakers and subwoofers. Housed in premium aluminum construction, this amplifier delivers low-distortion, acoustically accurate performance ideal for desktop, bookshelf, and outdoor installations.
