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 4.5741 out of 5 by 54.
Rated 1 out of 5 by from Promising, then DisappointedI needed a compact amp for an outdoor patio application. Signals are coming from an Apple Airport Express fed from my iTunes library. All my music is in Apple Lossless format. My need calls for clean but not loud sound (neighbors!). A 10w/channel class T I already had worked OK, but was not loud enough. This amp. should have been overkill in terms of power, and so should have matched the requirement.Initially, it seemed fine, but after only a short time, I was aware the sound quality was lacking in clarity and became quickly fatiguing. Experimenting across a range of known tracks revealed a sort of uneasy grittiness in the midrange. At slightly higher volume levels (about half way on the dial), or transients in the music, the grittiness gave way to painful distortion and proved totally unlistenable.(PE took it back for a full credit. I replaced it with Dayton's 15w/channel mini class D amp, which operates perfectly, and plays to very loud levels without any noticeable distortion.)Based on my experience, I cannot recommend this product. I question the 60w/channel claim, unless qualified with THD of 100%!!

Rated 5 out of 5 by from I'm just stunned...My DTA-120 arrived a few days ago. I had a difficult time believing that this tiny amp before me would impress much. That belief immediately went by the wayside when I connected the amp and listened. Phenomenal is the first word that came to mind when I listened to this remarkable little amp. I chose the Dayton amp over its primary competition, the Lepai LP2020, primarily because the Dayton has twice the rated power into 8 ohms. The Lepai's aesthetics also left a lot to be desired. I brought the Dayton home and started by giving it a challenge: inefficient speakers. I connected a pair of Pioneer Andrew Jones SP-BS41-LR bookshelf speakers, with a rated sensitivity of only 85 dB and an impedance of 6 ohms...a challenge for any amplifier. The speakers were mounted on 24" stands and were placed approximately 4 ft. from the wall behind them. Listened to a broad spectrum of music (rock, jazz, classical, etc.), and was pleasantly surprised at how the Dayton didn't seem to be fazed by anything. Listening to Laurie Anderson's "Bright Red", I could immediately tell this amplifier was done right. The soundstage was nice and wide, but I was stunned by how deep! I felt I could literally reach out and touch Laurie's face. Listening to Blue October's "Foiled", several of the songs on this CD are closely miked and the sound is appropriately "in your face". Listening to "Everlasting Friend" and especially "18th Floor Balcony", I was actually sad when the song ended...I didn't want it to end. That's how profoundly well-represented the music was by this amp. Turning to Mahler's 9th (4th movement), the intense gripping desperation of the 4th movement was palpable. Again...I didn't want it to end.I cannot recommended this amp strongly enough. I was absolutely floored by its performance. I still can't believe such powerful sound is coming from such a tiny amp. And you can't beat the price --- regular $139 but I got mine brand new for $99!Go to the Parts Express website and get yourself one of these gems RIGHT NOW! I will definitely be getting myself a second one of these soon!

Rated 5 out of 5 by from Exactly what I neededThe unit is small and provides good sound through my diy overnight sensations.The two make a very good pair and I would highly recommend it. The volume knob being smooth is a plus as wellThe only con I see is that the blue light is...well very bright. Its a little distracting at night so I just put a piece of tape over it.

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.
Date published: 2015-03-12
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.

Dayton Audio DTA-120 Class T Mini Amplifier 60 WPC

Why does the user manual specs say:        "Total Harmonic Distortion: <0.1% @ 1W per channel <10% @ 60W per channel" But the same manual and the online specifications also say:         "Audiophile quality sound with less than 0.01% THD @ 30W"

Asked by: C5pilot

Quick question about the power supply/cord. A comparable unit, the Lepai LP-2020A+ has a puny power supply. The power supply for the Dayton seems much more substantial. How does it rate voltage-wise with the Lepai.

Asked by: TulaneSteve
The Dayton uses a 24VDC 5A power supply due to its higher output power. The Lepai uses a 12VDC 2A supply.
