The Dayton Audio DTA-120 is a small and powerful Class-T amplifier that installs virtually anywhere.


Dayton Audio has revamped the popular DTA-100 mini amplifier with an all-new design that improves on every part of the DTA-100’s performance. The result is the Dayton Audio DTA-120 Class-T digital amplifier, and it’s everything you need in a mini amp, delivering the performance of enormous hi-fi gear, and smart features you’ll wonder how you lived without. And thanks to the space-saving design, it fits and installs practically anywhere!

 

Big-Amplifier Power

 

The DTA-120 amplifier delivers the power of a monster amplifier in a tiny package. Thanks to Tripath’s proprietary Class T technology, plus a robust Dual Parallel BTL configuration, the DTA-120 tackles the toughest speaker loads with ease, all 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 an 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.

 

Convenient, Small Size

 

With the DTA-120 amplifier, you get the most power possible from the smallest footprint imaginable. At under 3-1/2” wide, 2-1/4” tall, and 6” deep, the DTA-120 delivers more power per cubic inch than any other mini amplifier. All this is thanks to the revolutionary, cool-running Class T digital PWM 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-120 can easily drive HUGE speakers.

 

High-End Features and Quality

 

The DTA-120 amplifier delivers the features you expect in a much more expensive amplifier, at a fraction of the size and price. The housing is black-anodized aluminum, with a thick machined faceplate and a silky-smooth volume control. The rear panel features high-quality, gold-plated RCA inputs and shielded, gold-plated 5-way binding posts that accept any type of speaker cable. A high-current DC power jack is also used to ensure maximum power transfer to the amp. On the front panel, there’s a second 3.5mm audio input jack, as well as a ¼” headphone jack that receives its signal from a separate, high-quality headphone amplifier stage controlled by the main volume knob. (3.5mm to ¼” adapter included.)

 

Works With ALL Your Sources

 

In a world of changing digital and wireless specifications, the high-quality analog design of the DTA-120 remains virtually future-proof. Just connect it to any device with a headphone output jack and begin enjoying powerful, high-quality audio through your own speakers. Short signal paths inside the amplifier preserve all the quality of the input signal, and the DTA-120 automatically switches from the rear inputs to the front input when connected. No switches to flip, and just one knob. The DTA-120 is the perfect complement to your smartphone, tablet, laptop, PC, television, or any other audio source.

 

Head-Fi Friendly Design

 

The DTA-120 is the ultimate desktop amplifier. Not only can it drive even the smallest and least-efficient speakers to almost painful 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 the most demanding headphones to high listening levels while preserving clarity, detail, and a refined sonic character. However you like to listen at your desk, the DTA-120 is the perfect partner.

Good So Far

By: on 18 March 2015
Only had this little amp for 1 week. Went for the Dayton DAT-120 as I thought I might need the power. Currently driving a pair of 8ohm Kef C1 speaker with an ipod classic through a pure i20 dock. So far sounds very good and pleased with build and service.

Don't think twice

By: on 16 March 2015
This amp really is as good as everyone says, and an absolute no-brainer at the price. Don't even think about buying a cheap second-hand amp - get one of these. Mine came courtesy of LSK / Dayton, after one of my DTA-100s was DOA. Support from LSK was just fantastic. Do not have any hesitation buying one of these. They sound great, are excellent value and the support is second to none.
