Product description

Don't let the compact size fool you Dayton Audio's DTA-1 mini amplifier is a serious piece of audio gear. A proprietary Class-T amplifier chip enables the DTA-1 to be 88% efficient while still producing pristine, high-resolution output. This makes the DTA-1 T-Amp an obvious choice for powering high efficiency single driver speakers. Up to 15 watts of power per channel is on tap to drive desktop and bookshelf speakers, for the ultimate portable hi-fi setup at home or in your office. The Dayton Audio DTA-1 T-Amp can run off of 8 AA batteries for total portability, or the included switching power supply (with quick-release US and European style plugs) for stationary use. A rear mounted 3.5 mm stereo (1/8) audio input is provided. The amplifier also includes a 6 long, coiled male-to-male 3.5 mm cable for making connections to iPods, MP3 players, PCs, and portable CD or DVD players. Spring-loaded push terminals are incorporated for quick speaker wire termination. Intelligent short-circuit and over-temperature protection ensure amplifier longevity. The Dayton Audio DTA-1 is the perfect replacement for the now unavailable Sonic Impact 5066 NIB class T amplifier. Dayton Audio has taken the technology developed for the Sonic Impact 5066 and perfected it in this hand-held digital amplifier. Specifications: ; Power output: 2 x 15 watts RMS (into 4 ohms @ 10% THD), 2 x 10 watts RMS (into 4 ohms @ 0.1% THD) ; Efficiency: Greater than 88% ; Dynamic range: 102 dB ; Dimensions: 2 H x 6-1/8 W x 3-3/4 D

Awkward and solidly meh.

Reviewed in the United States on July 4, 2019

Verified Purchase

The Dayton DTA-1 amp is ... meh, even for the price. There are definitely better options, especially if you can find a good version of the Lepai 2020 with a good power supply.

The DTA-1 has an odd shape. The bottom has just enough unevenness to make it hard to stick down with double-sided pads or Velcro strips. The volume control is stiff and flat and not particularly easy to turn, and the fact that the amp is so light does not help usability. Sound quality is okay but doesn’t stand out. It only has one input, so you can’t have multiple devices connected (e.g. a wire and a Bluetooth receiver) - you have to choose one.

The one standout feature may be the fact that it takes batteries so it is theoretically portable, but if you don’t specifically need that then there are better options in this price range.

Fantastic amp for use with Chromecast Audio

Reviewed in the United States on March 2, 2017

Verified Purchase

I was completely blown away by the performance of this amp. I purchased it to power some speakers connected to a Chromecast Audio for an all home speaker system. When I first looked at this amp, I was concerned that it would not have enough power for the speakers I was using, or that I would have to max out the volume of the amp to get reasonable volume levels. The speakers I am powering are Boston Acoustic VR Surround Speakers. Once hooked up, I found that I had to turn the amp WAY down in order to not drown out the room. I am completely amazed at how such a small lower power amp can produce soo much volume and the sound is crisp and clear.

Some have pointed out that the blue "on" LED is too bright, which is true. It seems way brighter than it needs to be. But I found that you can cover the LED with a few pieces of Scotch tape which dims the light so that it still serves it's "on indicator" purpose. Or you can, like me, just put a piece of black electrical tape over it.

Terrible Build Quality Makes this a Risky Purchase

Reviewed in the United States on October 11, 2016

Verified Purchase

I'm honestly surprised that this product has been reviewed so well.

I got one of these, hooked it up, and was receiving a ton of distortion on the left channel. I moved the speakers around to verify it wasn't a problem with any of the other components, and was able to confirm it was an issue with the amp. I requested a replacement from Amazon, figuring "well, there's no way I could get TWO that don't work, right?"

I literally just got the replacement unit. Less than an hour ago. I hooked it up, and - yay! - no distortion. It was sounding good! I was just about to hook up a different audio source when the audio cut out. Just for a moment, at first. I listened for a few more seconds and it cut out again. Less than thirty seconds later, there was no audio at all. The unit completely died.

I just packaged it back up. I'm about to send both back, and request a refund this time.

Do yourselves a favor, and stay away from this mess. As other reviews have touched on, the build quality seems to be absolutely abysmal. Even if you get a unit that doesn't have any immediate defects, can you really trust that it won't break a week from now? A month from now?

driving a pair of KEF Eggs this little amp sounds pretty darned awesome at its price point

Reviewed in the United States on June 29, 2016

Verified Purchase

Pros: driving a pair of KEF Eggs this little amp sounds pretty darned awesome at its price point. What does "awesome" mean? It means that given an mp3 or streaming audio file, this amp delivers good volume and a sound that is open, bright, transparent. A bit thin and a bit "digital" compared to the $150 Monoprice 113194 which I also own, A-B compared to (BTW - Monoprice also delivers great sound at its price point). Driving the KEFs, mp3 audio no less satisfying than from a late 1980s Yamaha integrated amp I also own and A-B tested against (a $300 rig that was considered "entry audiophile" in its day). Now that's saying something given that the Dayton costs less than two week's of lattes.

Cons: Well, all that A-B testing put some wear on the really very flimsy speaker wire connectors at the rear. And one broke. No fixing it. Had to cut away plastic, and solder the speaker wire on to the lead. And: after about a year of sitting in a window location where there is afternoon sun...the plastic case has a bad case of leprosy. As others have noted, that blue light is way annoying (but nothing a bit of black electrical tape can't fix). Operation on 8 AA battery power? I don't think so - this churns through them in about 20 hours of use, and the case design is not going to be friendly to that kind of replacement action.

Inexpensive solution

Reviewed in the United States on October 2, 2018

Verified Purchase

I'm renting a furnished condo with a TV but no music system (other than through an app on the TV). I had an older Sonos Connect (no built in amp) and two bookshelf speakers. I'm not a tech guy but realized I needed an amplifier to run the speakers. This little gadget just works. I attached the speakers to the amp, the Sonos 'audio out' to the 3.5 mm female connector on the amp, turned the amp on, discovered the Sonos component on the Sonos amp, and, voila, music, sweet music. The unit employs a dial for on/off and, I think, power level. The dial works well and, so far, it hasn't been rotated to more than 50% of its range. No distortion has been noticed.

The amp is really light and the speaker connections feel a bit fragile. Of course, I'm not planning to move it around, so I expect there will be no issues with it. The blue light is bright so it's turned toward one of the speakers and now isn't noticeable.

I'll update this review if anything negative occurs. Otherwise, you can expect I continue to be impressed with this product.

Great sound, poor construction

Reviewed in the United States on July 19, 2017

Verified Purchase

Echoing/summarizing a lot of the reviews here.

Short story....

Sound: Perfectly fine. I have these paired with $3000 speakers that I purchased years ago for use with a tube amp. Excellent speakers. The sound from this Class T amp is quite remarkable for $25. And, I am streaming a compressed digital signal from my laptop via Airport Express, so there is not much chance the sound could possibly be any better.

Build: Shoddy. As I've read other people complain, the spring clip for the speaker terminal broke right out of the box. I fit the spring back in position but it's precarious and I'm sure the housekeeper will knock it well enough to explode parts. Too bad. With just a little better design (maybe for $5 more), this would be a transformative product.

Pequeña maravilla

Reviewed in Mexico on April 21, 2016

Verified Purchase

El DTA-1 es un pequeño amplificador de audio digital de clase T. Viene bien empacado, incluye el amplificador, un cable para conexión stereo de 3.5 mm, una fuente de poder de 12 v con adaptador europeo y americano y un pequeño manual.

La conexión de línea es muy sencilla, solo soporta una entrada de 3.5 en la parte posterior. Ahí mismo es posible conectar las bocinas a los conectores de clip. Cabe mencionar que no le puse 5 estrellas justo por la calidad de los conectores. El frente del amplificador solo cuenta con un control de apagado/encendido/volumen muy sencillo. El led azul de encendido es muy fuerte, habrá quién desee taparlo.

En cuanto al sonido, es capaz de entregar una salida teórica de 15 watts por canal a 4 ohm, esto quiere decir que usando unas bocinas de 6 u 8 ohms se tiene menos potencia.

El sonido es bueno y cristalino. Los amplificadores de clase T tienen la ventaja de entregar buena calidad de audio en un espacio reducido. Se escuchan mejor que los amplificadores de los años 70 y 80. El DTA-1 Tiene potencia suficiente para llenar con sonido una habitación pequeña a mediana. Inicialmente probé el amplificador con unas bocinas Dayton Audio B652-air y no me convenció mucho por la falta de bajo, sin embargo al conectar unas bocinas de piso Pioneer el equipo se escuchó mucho mejor. No se le puede exigir demasiado volumen sin esperar falta de distorsión, sin embargo por precio y portabilidad (se puede usar con 8 baterias AA) creo que es una buena opción para armar un equipo stereo con un presupuesto limitado.

Si desean más potencia y rendimiento (a un costo mucho mayor) recomiendo el amplificador de la misma marca Dayton Audio DTA-120 el cual entrega 60 watts por canal.

Reviewed in Mexico on March 25, 2016

Tengo opiniones encontradas respecto a este producto. Ya lo había adquirido en Amazon US, pero falló en menos de dos semanas. Primero el canal izquierdo dejó de funcionar, luego el botón de inicio (y también de volumen). Lo detesté porque me había agradado mucho la calidad del sonido y su diseño, pero tuve la gran decepción muy pronto. Evidentemente no pude hacer válida la garantía desde México así que me quedé con mi pedacito de basura.
Ahora lo adquirí en Amazon MX, con toda la esperanza de que no vuelva a fallar. Quiero aclarar que es distinto al americano, El logotipo de la marca no lo tiene grabado en la parte superior, tiene un pequeño sello en la parte posterior. Es claramente distinto. Voy a cambiar esta opinión conforme pase el tiempo y me siga funcionando.

Doesn't look like much but drives a couple old 5.2 Ohm speakers like a champ. Crisp sound at any volume; no hums, hisses, or other artifacts that I can detect. Great buy.
