S.M.S.L A50Pro 2.1 Amplifier – 100W Subwoofer, Bluetooth 5.0, HDMI ARC

Elevate your 2.1 audio with the S.M.S.L A50Pro

The S.M.S.L A50Pro is a compact yet capable 2.1 channel amplifier designed to bring bold bass and refined highs to your personal space. With 100W of passive subwoofer power and HiFi Bluetooth 5.0, this unit pairs seamlessly with passive speakers, a sub, a TV, or a range of digital sources to create a cohesive listening setup.

Built for flexible pairing, the A50Pro offers ten adjustable crossover frequency points. This lets you tailor the harmony between your main speakers and the subwoofer, helping you strike the exact balance you hear in your favorite songs or film scenes. The result can feel more integrated, with bass that breathes while mids and highs remain clear and present.

On the bass front, you can independently set the subwoofer volume from S00 to S99, adapting to intimate late-night listening or room-filling party energy without sacrificing precision. A suite of EQ tools and effect adjustments helps you shape the tone to suit different styles, from warm, cinematic sound to punchy, energetic tracks.

Compatibility is built in. The A50Pro supports USB plug-and-play, HDMI (ARC), optical, and AUX inputs, enabling easy connections to passive speakers, subwoofers, TVs, and more. This makes it a versatile hub for multidisciplinary setups—no matter whether you’re streaming, gaming, or watching a movie, you’ll have straightforward access to enhanced audio.

Digital efficiency meets quiet operation. Featuring Infineon digital silicon carbide power amplifier chips, the A50Pro delivers up to 92% energy efficiency, helping reduce power use over time. An electronic volume control keeps noise out of your signal path, preserving clarity during volume changes and transitions.

The bundle includes everything you need to get started: the A50Pro amplifier, power supply, user manual, remote control, Bluetooth antenna, USB and HDMI cables, plus a 12‑month worry‑free warranty and friendly support.

Two practical ways to use the A50Pro
