Product Details

Dayton Audio DTA-120 Class T Mini Amplifier 60 WPC

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. 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, but 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 -- 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 3.5 mm audio input jack, as well as a 1/4" headphone jack that receives its signal from a separate, high-quality headphone amplifier stage controlled by the main volume knob. (3.5 mm to 1/4" 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.

Dayton Audio DTA-120 Class T Mini Amplifier 60 WPC
Dayton Audio DTA-120 Class T Digital Mini Amplifier 60 WPC is rated 4.8293 out of 5 by 41.
Rated 5 out of 5 by from G R E A T Q U A L I T YHey there guys, greetings from San Diego, CA. I bought this Dayton DTA-120 mini amp and I'm pretty happy with it. It took about 7days for delivery. I'm a photographer so I want to listen to my music in full detail when sitting in my desk editing images, or I'll listen to my Martin Logan Motion 12's when away from the desk. I'm using this amp with a pair of bookshelf speakers: ENERGY C O N N O I S S E U R CB-20. They are rated at 8ohms and max wattage is 150. Also I don't have a subwoofer connected. Speakers are set up one at each side of my laptop. I get no hissing, the only thing is when I turn the unit on I get this little static/click noise which lasts less than 2 miliseconds(not bad at all). The sound is clean and strong. I have a Macbook Pro 15" Retina, most of my files are AIFF equivalent to FLAC and they sound great. Wish You Were Here by: Pink Floyd sounds crisp and clean, with clean bass. Skrillex (Dub Step) sounds great too. Piano music, hip hop, acoustic it all sounds great! The amp is about as big as an iphone 6 and about 2"inches deep. It comes with everything you need except speaker wire. Banana plugs, 3.5mm cable, two channel RCA cable about 4"inches long. Very well packed, not a scratch on mine. It has a bright blue led light which I covered with gaffers tape, I just poked a little hole so the light wouldn't be so intruding. Heat isn't bad either it barely produces any. I had purchased a mini t amp from Orb Audio but was very weak rated at only 20watts per channel so it went back. If you have questions on their speakers I tried them too the little spheres MODX not to great and they're expensive too. $342USD for 2 little spheres polished metal finish.

Rated 5 out of 5 by from The best little amp available!The DTA-120 actually replaced the original DTA amp I bought previously. The older amp was great except the jacks on the back weren't very good. When I pulled out my interconnect, both female jacks came out with it. Yuck. Plus, I changed my speakers from the Insignia NS-B2111's to my Magnepan MMG's(on custom-made Mye stands). The MMG's are 4 ohm and not efficient at all(86 db). The jacks on the DTA-120 are better. This is important because my speaker wires are big and heavy. Along with my Onkyo C-7030 CD player, I am getting excellent sound. In my 16x12 room, the speakers are set-up 9 ft from the back wall, angled(tweeter strip on the inside)in. If your speakers are positioned 2-3 ft from your back wall, you are MISSING OUT. Near-field positioning, especially with Magnepans, gives maximum clarity, three dimensional imaging, and the tightest bass. If you enjoy classical music, acoustic jazz or folk or light pop music, this system will make you forget all about TV or videos. The DTA-120 is so good, I don't know really know how good it could sound with a much better source that I have. To sum up: the amp's sound is lightning fast, three dimensional, tonally wondrous, with bass you can't believe coming out of that tiny little box, plus, dynamics that'll make you smile. And, with the volume at about 11:00 or 12:00, the sound is pretty loud. I've been an audiophile for a long time and I've owned many, many amplifiers. The DTA-120 is the best amp I've owned. The great price is not bad either.

Rated 5 out of 5 by from Great Amp !!!! Highly recommendThis amp was recommended to me by an audio professional. DON'T BE FOOLED BY THE SMALL PACKAGE .... It is wonderful.. I plan to buy another one..

Rated 4 out of 5 by from Very good soundWhen this arrived I hooked it up to my Vandersteens (2c's) just to check it out. That was two weeks ago and I haven't pulled it for the bedroom yet. It is a fantastic-sounding amplifier with good imaging and tone balance. The amplifier I normally use with the Vandersteens is a Sim Moon I-3 SE. There is a problem with the power supply connector on DTA and I replaced the power supply with another. Quality control, I'd say is an issue with this, because if anyone had so much as plugged it in they would have caught the problem, and it is such a pain to send them back.

Rated 4 out of 5 by from Excellent product for the money.I bought two of these amps to power some modest sized speakers that I built with Dayton drivers for my kids. The amps are small and simple, and sound a lot bigger than they are. I can't give them 5 stars, because that would imply they are what they're not, which would be something comparable to my Audio Research gear. What they are is great little amps for the price, and I recommend them highly.

Rated 5 out of 5 by from Great Desktop Solution / TriTrix AmpI bought this as part of my downsizing as I'm soon to be married and will reducing on my personal space... Having had a 5.1 system set up in my bedroom before which is now mostly being split up into our home theatre system, I needed an amp to keep my TriTrix speakers kicking with my computer set-up. I searched locally (Lower Mainland, BC, Canada), but had a hard time finding as elegant a solution as this for such a low price point, and I also was quite happy with the TriTrix kit I had ordered in the past from Parts Express.I was worried that this amp would not provide enough power, as I was going from an Onkyo 5.1 receiver which was rated for 400W, but it only took a moment of turning it on to realize that this thing has more power available than I'll ever need to use for my purposes. I listen to a lot of music, primarily Classic Rock, New Folk, and some other odd bands here and there, as well as gaming and watching Netflix. I rarely turn the volume dial past the half-way point, and that is with my volume set quite low on my computer as well.I'm not a tried and true audiophile, but I like to think it provides a more dynamic sound than the receiver I was using before. The headphone jack is also a definite positive, and seems to be a good match with my Audio Technica ATH-M50's. I also appreciate the 3.5mm input on the front of the unit, which which automatically overrides the RCA inputs on the back, making portable sources easy to use. The only negative thing I can think of is that the blue LED that lights up when the amp is turned on burned out within a day, but I don't care all too much. I would definitely recommend this product, and I would buy again if I ever need to set up another 2 channel system.

What are the dimensions of the power supply?

Asked by: Kevin P
The brick dimensions itself are 6-5/8" x 2-5/8" x 1-5/8". I would recommend allowing 10" overall for the length to accommodate the cables.

Can this be used on passive subs?

Asked by: bumpo
Thank you for your question!I would have no qualms recommending this amplifier to you, for powering passive subwoofers. As long as you stay above the minimum impedance of 4 ohms per channel, and do not bridge the amplifier, you will be safe.If you need more power, I would recommend the Dayton Audio SA230 subwoofer amplifier: http://www.parts-express.com/dayton-audio-sa230-230w-subwoofer-amplifier--300-813

I'm contemplating building an IPOD speaker system inside a small metal ammunition can. Could I power this amp with a couple of 12v SLA batteries wired to produce 24v? Thank you.

Asked by: Rodney426hemi
Yes this will work with two 12V SLA batteries in series.

I bought this amp in 2011. The amp worked great for nearly 4 years, but one day it just stopped working. I turn the knob and the blue light might seem fine for a few minutes and then it starts to fade. How can I figure out what's wrong with it?
