Product Details

Dayton Audio DTA-120 Class T Mini Amplifier 60 WPC

Everything You Need in a Mini Amp

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 Mini Amplifier 60 WPC is rated 4.6275 out of 5 by 51.
Rated 5 out of 5 by from Well Built mini powerhouseWas surprised even after all i read about this little fellla as to how much output he has. Bit cold down in the low end but good solid control up to high volumes. I enjoyed the fact the switchmode psu is able to accept a 240vac fig 8 style kettle lead too. No bulky adapter for me. (I'm from Australia). Shipping took 17 days from start to finish. So lets say 13 work days from America to Australia aint too shabby.

Rated 1 out of 5 by from 10% THD max, both channels drivenPay attention to the following: "10% THD max, both channels driven) • Total harmonic distortion (THD): <0.1% @ 1W • Frequency response"I can confirm the distortion is high. Would not recommend it to anybody.

Rated 2 out of 5 by from Stopped working in under 2 yearsPurchased this amp less than 2 years ago, and the left channel has stopped working. I was happy with the size of the amp, perfect for a computer desk.

Rated 4 out of 5 by from works well, quiet powerDrives my Dayton indoor/outdoor garage speakers to uncomfortable levels very easily with very little detectable noise. Very satisfied with my purchase.

Rated 4 out of 5 by from Rocked the GarageI purchased the Dayton DT120 amp for use in a garage audio system. I liked the power, closed case providing dust protection, and small size for convenient installation under my work bench, yet still out of the way. I also liked the industrial chic look for the garage/man cave.The amp arrived nicely packaged. It looks great and has a nice fit and finish. It looks like quality. The separate power source is hefty, nearly the size of the amp. The features are minimalist, but it has exactly what I need.The amp turns on with a cool blue light and an old school pop in the right speaker.I paired the amp with Pioneer sp-bs22-lr speakers. I used my iPod for an input source, which can be connected with an included double male cable to a 3.5mm jack in the front. Very convenient, who needs bluetooth. Installed in a 21’ x 25’ x 9' space, the little amp had enough power to effortlessly drive the speakers to a rafter raising volume, yet stayed as cool as a cucumber doing it.A couple of complaints. If I touch the iPod’s metal case, there is a notable hum that goes away as soon as I put it down. If I just touch the iPod’s glass screen, then no hum. If the iPod is plugged into the AC outlet while playing through the amp, there is significant background static. Enough so that you really don’t want to listen to it while recharging. I have heard no other background noise, just clean sound.All in all I am happy with the amp, impressive power in a small package, quality build, nice looks, 3.5mm front jack.

Rated 5 out of 5 by from Surprising PerformanceI compared this amplifier against a matched pair of carefully restored and matched McIntosh MC60 vacuum tube amplifiers and against a classic QSC stereo 1000 watt solid state bipolar AB class amplifier with all other components in the signal chain remaining unchanged in the comparisons. The speakers were high efficiency 97 db'1W/1M JBL professional systems. All three amplifiers easily powered these speakers in a large well-controlled listening space and provided adequate power for serious listening.There was no discernible difference in sound stage or imaging between the amplifiers because these characteristics are primarily dependent on the speakers and room acoustics. There was no discernible difference between the QSC and Class T DTA120. The QSC was, of course, providing only a small percentage of its maximum power while the DTA120 was outputting an estimated 20-40 watts per channel. The mid band performance compared favorably with the MC60s, but the extreme upper end performance of the DTA120 was superior to the MC60 and this is not surprising considering the much wider bandwidth of modern electronics compared to what was available 60 years ago. What I did notice over long listening periods was very little listening fatique with the DTA120 because the music sounded the way I thought it should sound.The real difference is that the DTA120 with the power supply is 1/50 the weight of the two MC60s and about 1/20 the weight of the QSC . This little gem brings us out of the electronics iron age.

Dayton Audio DTA-120 Class T Mini Amplifier 60 WPC

Is this amp output bridgeable? Will it run at 8 ohm mono?

Asked by: Captardy
This amplifier is not bridgeable but it will run 8 ohms on one channel without a problem.
Answered by: MattP
Date published: 2015-03-20

Will this amp work with 4 ohm speakers (Epos Epic 2)? I'll be connecting it to my Marantz SR6008. Thanks...

Asked by: BillinMA
Yes this will work with 4 ohm speakers.
Answered by: MattP
Date published: 2015-03-04

Are there different size banana plugs for the speaker binding posts? Will spades work? How do you connect to a DAC?

Asked by: withiniswithout
This will accept any normal banana plug without a problem and spades will work as well. You would connect the analog RCA output on the DAC to the RCA inputs on this amplifier.
Answered by: MattP
Date published: 2015-03-02

If I plug a headphone extension cable in to the headphone jack will that cut power to the speakers, or will the speakers continue to work until I plug headphones in to the extension cable?

Asked by: pauldast
When a headphones are plugged in the speaker output is switched off automatically.
Answered by: MattP
Date published: 2015-03-26

Is it possible to use this amp with the Micca MB42x which are labeled as having a impedance of 4-8 ohms? Could I modify the amp or speakers without changing the quality to make this work without damaging the amp?

Asked by: Maxwell
Yes this amp will drive 4 or 8 ohm speakers without a problem.

I'm running my orthodynamic HE500s off the speaker taps on the 120, and so far it sounds decent, but when the volume is low, there is a ton of noise. Is this an impedance issue or something else?

Asked by: JoeDoe
If you are powering the headphones with the speaker outputs and not the headphone output, it is probably a combination of impedance and headphone sensitivity. The speaker outputs are only designed to power speakers. I would try using the headphone output to see if you still get noise, or see if you get noise by plugging a standard speaker into the speaker outputs.
