auna BT-Bro Mini Stereo Amplifier Class-D Bluetooth Aluminium Black

Ultra compact Mini stereo amplifier with 20W + 20W RMS output and Bluetooth interface for wireless music playback.

3.5mm jack input for connecting external audio devices such as MP3 or CD players and computers.

Includes AC adapter, jack cable and banana plugs.

The auna BT-Pro Mini Amplifier combines wired and wireless connection options with powerful performance and an ultra compact design.

The small, technically efficiant digital amplifier boasts 20 watts per channel and thus offers enough power reserves to provide small to medium sized bookshelf speakers with strong sound.

The integrated Bluetooth interface allows for wireless music streaming- at a range of up to 10m- from smartphones, tablets and laptops. A screwable and adjustable rod antenna guarantees the proper signal transmission.

Through a rear built-in 3.5mm jack input, wired devices such as mobile phones, MP3 or CD players and computers can find their way into the sound. The audio signals then reach the connected speakers through the rear speaker jacks. A discreet LED on the front panel offers information about the operation and Bluetooth status.

The ultra-compact design will impress with its lightweight aluminum body together with a brushed front panel and rounded edges, thus offering an unforgettable acoustic and visual music experience. Controls such as the combined volume control have also been made of aluminum and guarantee maximum control. The lightweight aluminum design also provides good heat dissipation. All speaker terminals are equipped with gold-plated contacts.

A jack cable and a set of banana plugs are included with the system so that you can start right out of the box.
