amp - bluetooth - USB - RCA input - aux jack 3.5mm 2x45watt under 4ohm - 12volt or 220volt

Do you want a Bluetooth amplifier for patio speakers, sauna speakers, bathroom speakers or a garage? Or a more powerful amplifier for computer speakers? Or build a simple sound system even in a bedroom, a child's room, a student dorm or a basement gym?

The Ai-Sonic BT-A255 is the perfect solution as an amplifier if you want to listen to music via Bluetooth. The small physical size makes the device very easy to place in virtually any space. In addition to Bluetooth, the audio sources are USB and a line-level RCA / AuxIn input.

You can connect a USB stick to the USB port, you can exchange songs with the included remote control. The remote control needs a visual connection to the amplifier, it works with infrared. You can connect any device that provides line-level sound to the RCA jack. With the included 1.5 meter long cable, you get an RCA output with a 3.5 mm AuxIn connection.

However, the best feature is Bluetooth 4.2 through which you can get high quality audio wirelessly from your phone, tablet, computer and almost anywhere.

The power of the device is sufficient to play any conventional speaker even at high volume. You can also play loud without worry, because the power supplied by the amplifier to the speakers will not be distorted. If the output signal starts to distort, the amplifier automatically limits the level so that the signal remains clear. Automatic limiting also handles situations where the amplifier starts to overheat. The speaker lines are protected against short circuits. If the speaker cable is damaged, the device automatically protects itself. If you want even more power, you can bridge the amplifier (minimum load 8 ohms).

Bluetooth range is about 15 meters in open mode
