## Overview

The Dayton Audio DTA-1 is a compact Class-T digital amplifier delivering 15 watts per channel with 88% efficiency. It supports both battery (8 AA) and AC power, making it ideal for portable or stationary use.

## 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

Review: Fantastic Amplifier. Thinking of buying a second one - I have been looking for some time for a small portable amplifier to power two small speakers that I installed on my power wheelchair. I came across this amplifier after searching everywhere for an amplifier that could power regular speakers using a small mp3 player. When this item arrived, my first impression was that maybe I wasted my money. The amplifier is much smaller than it appears in the pictures. I thought for sure that with it being so small, it was probably just a gimmick item like the little amplifier one might find in tiny portable speakers. The amplifier was perhaps just a little bigger than two decks of cards. Assuming that I had wasted my money, I set it aside for a while and almost forgot about it when my sister dropped by to ask me for some help in hooking up speakers to her laptop computer to use at her daughters birthday party. My sister had rented a hall and had wanted to use her laptop for the music. Not understanding anything about the poor sound quality of a low-end laptop computer, she brought over her laptop and these two gigantic speakers that were originally out of a movie theater. I first tried some amplified computer speakers I had thinking that there was no way to power gigantic speakers with a little low-end laptop computer. As expected, the sound was not great using the computer speakers which were amplified. Then, just out of curiosity, I hooked up this little Dayton Audio DTA-1 Amplifier. I couldn't believe it. Not only did it power these two gigantic speakers (out of a laptop headphone jack no less), it had tremendous sound quality. The volume was very good... loud enough that I only had it at half volume... more than loud enough to use to power the speakers for DJ at this kid's Disco Birthday party. I am now thinking about getting another amp for my home computer system. I can't wait to plug it into my wheelchair's speakers... I might move my chair by sound alone LOL. I like that this allows using both battery and plug in power. It has fantastic sound quality. It has clips for hooking standard speaker wire. Includes small cable for hooking to headphone jack. You might need somesort of converter if plan to use for an Ipod. Overall... it was worth the price and seems to be a great product. One drawback to this amplifier is its battery case. It is a pain to insert the batteries.
Review: Updated: It died after 1 year 5 months. Amazing little amplifier - Our house has speakers built into the ceiling of the bathroom, installed by the former owners. I decided that since they exist, we should make use of them. I bought the Dayton Audio DTA-1 after reading about how Class T amps deliver sound that doesn't seem possible for their size and price and for the amount of heat that is (not) generated by the amp. Class T amps are extremely efficient, hence much less waste heat. When I took it out of the box, i was skeptical. This thing weighs almost nothing and has a pretty minimal plastic housing that is attractive but pretty cheap. All doubts were laid to rest when I hooked this thing up, though. Given the sound it is capable of producing, I almost LIKE that it feels so chintzy because I'm reminded of what a bargain it is! Setup: I used an Apple Airport Express base station for the audio gateway from my iPhone. Airport Expresses are actually routers but you can configure them to connect to another, non-Apple wifi network in "client mode" for this purpose - and also sharing hard drives, printers. This is a setup I highly recommend as it is very discrete and gives you almost unlimited options of source content in the palm of your hand (there's an app for everything - internet radio, itunes, the Remote app, etc. etc.). You get total control over the volume, etc. from your iPhone. There is a 3.5mm jack on the Airport Express that connects to the DTA-1 using a supplied (though short) cable. When you are listening to audio on your iPhone (or iTouch), there is a small icon in most audio apps that lets you stream audio to any "Airplay devices" that it finds on your network (Airport Express being one, Apple TV being another - also fantastic with video too!) over your wifi network. Excellent, excellent technology. The sound quality is even very good! Back to the amp's performance: This little amp output sound that was warm with clear crisp highs and tight bass. It isn't going to go up against high end audio equipment but for the price and size, it is absolutely incredible! You get decent volume, though you can't get rock concert levels out of it. This should go without saying, as it is rated at 15 watts/channel. When no signal is being output but the amp is on, it is dead silent. I think this is due to the Class T and Class D's chip architecture - it is either on or off. An added bonus is that you can load this thing up with batteries and it goes mobile. I have no desire to do this but it is a cool trick. I didn't try it so I can't speak to how it sounds when on battery power. It uses 8, 1.5 volt batteries for 12 volts total, which is what it gets from the included wall wart power supply so I don't imagine it would be any different - at least while the batteries have plenty of juice left. Overall, this little amp is a steal for adding an additional zone to your audio system. It won't hold up driving your main speaker setup but, as many of the other review say, if you have reasonably efficient speakers, you'll get a LOT of good sound from a tiny and extremely cheap package. As a side note, I also bought an Audiosource AMP-100 for two additional zones (it has "Speaker A" and "Speaker B" switches) and this little amp sounds about as good as the AMP-100 when driving one set of speakers. It is 3x the price, many times the size and likely uses more juice as it is Class A vs. the DTA-1's Class T. I wish I'd bought two more DTA-1s instead of one AMP-100. PS: Sorry for being an Apple fanboy. The Airport express setup is such a good match for this product, so I included the setup prominently in the review. UPDATE: I loved this little amp when it worked but alas, it died on me. It lasted 1 year 5 months. I had it running a pair of speakers in the ceiling of the bathroom. It got used every single day... I listen to podcasts in the shower. It was well away from the shower and while there was moisture, it couldn't have gotten that much. Also, when I was trying to troubleshoot it when it died, I wanted to rule out the power supply. To do this, I tried putting batteries in it. FAIL! I didn't actually get to try it because the way the battery compartment is designed, you have to basically rip off the spring contacts from the top row of batteries to get the bottom row in. (8 batteries... 4 on the bottom, 4 stacked on top.) It sounds trivial but it really makes it almost impossible to put batteries in the damn thing and make sure all 8 springs are in tact. If you plan on using batteries to run this thing, look elsewhere.

## Questions & Answers

**Q: So if I have 6 ohm 15w-150w speakers is this sufficient or would I be better off with the DTA-100  ?**
A: It depends more on the sensitivity rating of the speakers (like, 90db at 1 watt/1 meter), and how loud you need it to be. For typical home theater bookshelf speakers, this amp is enough power for small rooms or enough power to supply background music in a larger room. The distortion increases pretty rapidly once you get over 10W peak output though, so the louder you need it, the worse its going to sound if you need more than about ~80db power at more than 2-3 meters away. Just keep in mind - if you're using this to upgrade from tiny computer speakers or the built in speakers on a TV, its already a lot more power than those systems are capable of, but a lot less power than a well built home theater receiver. tldr version: Its probably enough, but I don't have enough details about what you're using it for to be sure.

**Q: what guage wire will fit? 14g or 16?**
A: While the terminals appear to have large enough openings to accomodate 14g, you really dont have to go there (unless you are planning on using a few hundred feet of speaker wire). The resistance of, say, 20 ft of 16g Cu wire is only 0.08 ohms, or 100x less than the impedance of an 8 ohm speaker: i.e., absolutely negligible.

**Q: at the top of the page it says "Soft turn-on eliminates annoying speaker pop"  but in the video he mentions popping when turned on or off.  ??,  tx**
A: I have 4 of these. None of mine pop AT ALL when I turn them on or off.

**Q: Besides connecting speakers to amp, does it have a 3.5 mm headphone jack OUTPUT ?**
A: Nope, Pretty simple unit, One 3.5 input & two speaker terminals. You would just need a splitter before the unit. One to unit other to whatever...

### ⭐⭐⭐⭐ Great T-Amp
*by M***A on June 3, 2015*

Somewhat Relevant Background Info: My family has an old sony receiver for the family room. Every powered channel (not the subwoofer output) stopped working. I opened it up and everything seemed fine except for the fuses between the main laminated core transformer and the main bridge rectifier. I replaced the fuses with the same type and rating but they kept blowing up. I think the bridge rectifier is broken and is somehow creating a short circuit. I don't know for sure because I haven't tried replacing it yet. Because of this, I had the opportunity to bring our family room's speakers (a pair of Niles CTRBx center channel speakers)in our computer room for near-field, on-axis listening. They're huge on desktop. Both of my parents (I am a highschooler at the time of this review.), immediately complained but when my dad heard one of the best speakers in the house near-field he stopped. My mom still complains but hey, my dad is still on my side. Once we get an amp(either the smsl sa50 or a refurb receiver from accessories4less) for the family room its over. I'll just save up for a used niles ctrbx (We have 3 of them. To make two stereo sets i only need one more. That way, I know i won't need to buy a separate subwoofer when i get a job. Actual Review for the Dayton DTA-1 (Sonic T-amp clone): Build I was extremely surprised how small and light it is. This is my first t-amp. Its so cute. The overall build quality is good. Unlike most t-amps, it has a 3.5m trs input instead of a set of rca jacks. The spring clips on the back are annoying because they don't take low gauge (thick) wire. The on and off mechanism seems like it will get loose over time but i can't say for sure because I've only owned this for a few weeks. Installing the batteries in the compartment is a pain. The blue LED needs to be covered with tape or some black sharpie. This along with the sub-bass roll off took off a star. Power http://www.datasheetcatalog.com/datasheets_pdf/T/A/2/0/TA2024.shtml I don't have any equipment to measure it but the datasheet for the IC should be a good estimate. At 8 ohms, it should output around 5 clean watts per channel. This is more than enough for near-field and enough to fill small-medium sized rooms as long as your speakers aren't insanely insensitive (under 86db at 1 meter with one watt). You'll probably have trouble with larger rooms unless your speakers have an insanely high sensitivity over 96db. If you'd like a rough estimate of how loud it will get in your listening environment, definitely check out the link below. http://myhometheater.homestead.com/splcalculator.html With battery power, it can get pretty loud (the speakers i used to test this amp have a sensitivity of 90db) but that will drop along with the batteries' voltage. I don't have any hard numbers but reduced output is guaranteed because its a 12vdc 2 amp wall-wart vs 8 aa batteries. It doesn't have an absolutely silent turn on but it does have some kind of initial pop protection. Its certainly better than nothing *Cough* Lepai *Cough* *Cough* Audio quality There is a bit of a sub bass roll off starting at around 60hz-70hz compared to the av receiver we were using. Input decoupling and power supply decoupling capacitor upgrades are pretty popular for this amp. http://www.diyaudio.com/forums/class-d/50870-sonic-impact-5066-parts-list-modifications.html http://www.michael.mardis.com/sonic/start.html Aside from that, I have no complaints, even when comparing it with full size av receivers. Its pretty much neutral as far as i can tell. The soundstage and imaging is very good with anime and music. If the sub-bass roll off bothers you, try out an eq. EqualizerAPO is a great system-wide for windows. You have to edit a .txt file and follow a certain format to use it properly. http://sourceforge.net/p/equalizerapo/wiki/Configuration%20reference/ Capriccio and onkyo hf player are good ones for IOS. I'm sure you can find something on the android play store. My top 10 anime: 1. Steins;Gate 2. Code Geass 3. Angel Beats 4. Psychopass 5. No Game No Life (Beware of Ecchi... If you don't know what "ecchi" is, you'll find out within the first 30 seconds of the anime) 6. The Devil is a Part Timer 7. Full Metal Alchemist Brotherhood 8. Death Note/AOT 9. Sakurasou no pet na kanojo 10.Plastic nee-san Should you binge on all of them this summer? Anime is not a one size fits all type thing. Go talk to someone who knows you well and watches a lot of anime. I'm sure they'll be glad to help you as long as you don't mention "One Piece", "Fairy Tail", "Bleach" "Naruto", etc...
