The SMSL A50 Pro is a powerful integrated mini amplifier for home audio, desktop audio, TV sound, studio monitoring, and compact HiFi setups. With 2 x 70 watts into 4 ohms plus 100 watts subwoofer power into 2 ohms, the 2.1-channel amplifier delivers punchy stereo sound with a dedicated subwoofer channel. HDMI ARC, Bluetooth 5.0, digital connectivity options, equalizer functions, high-pass and low-pass filters, and a sturdy aluminum chassis make the A50 Pro a modern solution for music, movies, gaming, and streaming.
Powerful 2.1 Audio Performance
The SMSL A50 Pro combines two stereo channels with a dedicated subwoofer output, making it ideal for compact speaker systems that need extra bass foundation. Rated power is 2 x 70 watts into 4 ohms and 100 watts into 2 ohms for the subwoofer. That creates a flexible 2.1 setup that works well for bookshelf speakers on a desk, living-room applications, soundbar projects, or small DIY audio systems.
Modern Connectivity with HDMI ARC and Bluetooth
Thanks to HDMI ARC, the amplifier can be easily integrated into a TV setup. Bluetooth 5.0 enables wireless streaming from a smartphone, tablet, or notebook. The A50 Pro convincingly covers common search terms like Mini Amp, Stereo Amplifier, Bluetooth amplifier, Desktop Amplifier, TV Amplifier, and 2.1 HiFi Amplifier. The variety of digital inputs ensures straightforward integration into modern audio environments.
Clean Sound with Precise Tuning
Two Infineon MA12070P amplifier chips form the technical foundation for efficient amplification, low distortion, and clear reproduction. A signal-to-noise ratio of 102 dB and distortion of 0.013% support clean sound presentation. In addition, several equalizer presets and high-pass and low-pass filters are available so you can tune speakers and subwoofer to the room, music style, and your personal listening preferences.
Robust Construction and Easy Operation
The solid aluminum chassis looks premium, is durable, and fits well in living spaces. A bright display and intuitive control panel make on-unit operation easy. An IR remote control is also included, so you can adjust volume and settings comfortably from your listening position. With dimensions (D x W x H): 134 x 33 x 103 mm, the amplifier remains pleasantly compact and can be discreetly integrated into almost any setup.
Efficient for Everyday Use and Multimedia
The A50 Pro runs on 12 - 24 V DC, consumes 36 watts, and requires only < 0.5 watts in standby. The frequency response of 20 Hz - 20,000 Hz covers the classic HiFi range and makes the amplifier a practical solution for music enjoyment, movie soundtracks, PC audio, active TV expansion, and compact subwoofer systems.
