Dayton Audio has updated the popular DTA-120 mini amplifier with the addition of Bluetooth audio but keeps the great sound and outstanding quality of the original DTA-120. The result is the Dayton Audio DTA-120BT2 Class D digital amplifier. Its everything you need in a mini amplifier, delivering the performance of large hi-fi gear paired with smart features, youll wonder how you lived without... and thanks to the space-saving design, it fits and installs practically anywhere!

The DTA-120BT2 amplifier delivers the power of a monster amplifier but in a tiny package. Thanks to its Class D technology, plus a robust Dual Parallel BTL configuration, the DTA-120BT2 tackles the toughest speaker loads with ease -- while delivering the sound quality and low distortion of a conventional Class AB amplifier. The dual-power-chip design delivers 60 watts RMS per channel of efficient power into a 4 ohm load (up to 120 watts total), and 40 watts RMS into 8 ohms, continuously, with no reduction in output. That means powerful bass and clear output that keeps on going, even with the most demanding speakers.

With the DTA-120BT2 mini amplifier, you get the most power possible from the smallest footprint imaginable. At under 3-1/2" wide, 2" tall, and 7-1/2" deep, the DTA-120BT2 delivers more power per cubic inch than any other mini amplifier. All this is thanks to the revolutionary, cool-running Class D amplifier technology and the extruded aluminum heatsink case. The robust external switching power supply hides out of sight. But since it can supply high current with even higher peaks, the DTA-120BT2 can easily drive HUGE speakers.

In a world of wireless connectivity, the DTA-120BT2 offers a high-quality aptX Bluetooth connection as one of its multiple source options. Also offered are 3.5 mm and a pair of RCA auxiliary inputs to satisfy your analog input needs. The short signal paths inside the amplifier preserve all the quality of the input signal. No switches to flip, and just one knob. The DTA-120BT2 is the perfect complement to your smartphone, tablet, laptop, PC, television, or any other audio source.

The DTA-120BT2 is the ultimate desktop amplifier. Not only can it power the most inefficient speakers to incredible levels without strain, making it perfect for powering desktop mini-monitor speakers, but it also offers a separate solid-state headphone amplifier stage capable of powering even high-impedance headphones to high listening levels while preserving clarity, detail, and a refined sonic character. However you like to listen at your desk, the DTA-120BT2 is the desktop companion.
