Dayton Audio DTA-1 Class T AC/DC Battery Powered Mini Amplifier 15 WPC

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. Includes 12 VDC, 2A power supply.

Rated 5 out of 5 by from small clean ampI am using this amplifier to power speakers for a computer. The size and the lowdistortion made this a choice that works very well for me.

Rated 4 out of 5 by from Good amp on a budget!I am just now testing this little amp on Dayton 652, Radio Shack Minimus 7 (they have a reputation for being the being the most honest and revealing monitors ever made), Wharfedale Diamond 7 Anniversary, and Jamo 601 speakers. I have to agree with those who compare this to a vintage small tube amp. It has that light fluffy quality. It also has that problem with mid range emphasis. On many speakers it will sound "nasal", but every detail still makes it through. In a pinch for budget, I would select this over any *&^%!uy (big box store) offering up to 300 bucks, because I hate muffled sound, and this little unit is wide open sounding.Over all, if you you are on a real budget, this may take getting used to, but once you do, I think it'll be hard to switch to any higher powered amp once you do. It has been my experience over a 51 year lifetime that once you start to listen to finer sounds, the big kaboom just hurts and sounds silly, and I was fascinated at age 4 with my mom's vintage tube console stereo. For almost 10 years now, I have been hooked on a 5W/channel Marantz/Superscope amp (yes, FIVE watts, not 5 hundred) that has BUMPED everything else off the shelve after having the chance to try a lot of amps due to my HiFi and record store buddy.For an upgrade to better sound, the DTA 100 (no longer made, but have and LOVE it) or its heir, the DTA-120 will go a long way towards being spoiled for high end equipment, because at these prices saving a big case, remote, equalizer, balance, multichannel control, etc., means you get pure amplification without the bells and whistles and without the cost. That is worth a LOT more than getting one of these "Home Theatre" box store junk units with muffled sound and all sorts of problems that will make you return them after a few days ;)Overall, I think after some break-in, this will be a pleasurable unit in a secondary setting.

Rated 5 out of 5 by from you need realistic expectationsI bought one of these a few years ago and I just bought another one. At 10 watts/channel I don't consider this an audiophile amplifier. I use my amplifier connected to my computer to drive old wooden enclosure full-range Radio Shack speakers. The sound quality is way beyond much more expensive computer speakers. With automobiles the saying is "there is no substitute for cubic inches". With audiophile amplifiers there is no substitute for output power (I would include output current), so this amplifier doesn't qualify. With speakers there is no substitute for cubic inches (enclosure volume), so my separately amplified wooden enclosure Radio Shack speakers beat plastic computer speakers hands down.

Rated 5 out of 5 by from Great Purchase!I recently stumbled upon this amp while working on a "McGiver" like project. The more I read and looked into this project the more I learned. I am very non-technical when it comes to stereo equipment. Anyway, I decided to hook this amp to a 40+ year old Motorola receiver and 20+ year old speakers. What I great sound! I was amazed at what this inexpensive amp did to my old system. I am not looking around the house to see what other improvements can be made.

Rated 2 out of 5 by from nice little amp - but gooey sticky messy caseI have several tri-path amps. When Dayton changed the case from the silver plastic to this black rubberized one, it was a big mistake. In hotter climate, the "rubberized" material turns into a sticky mess in about 2 years. Kinda like rubbing pine sap all over something - not pleasant. Sounds great, but looks and feels like sh--. Check the picture if you don't believe me. You will need to wash your hands every time you touch it.Dayton...Fix the case issue, and you will receive 5 stars.

Dayton Audio DTA-1 Class T AC/DC Battery Powered Mini Amplifier 15 WPC

If I were to use this amp for moderate listening with a pair of b452 speakers and a 10" Dayton subwoofer can I expect the gain on the subwoofer to be adequate? Considering the high level inputs are normally used with 100wpc receivers.

Asked by: Mikey330077
Yes this will work fine using the speaker level inputs on a powered subwoofer.

I have EPI 50 speakers that I am using with the Dayton Amp. They are not efficient. Is there a way to use two of the amps to get more sound volume?

Asked by: SoundmanTim
These are not bridgeable so they can only produce their published power per channel. You might consider something like our Dayton DTA-120 amp which is 60 watts per channel.

How could I hook up a small subwoofer?

Asked by: 68VWDBL
The subwoofer would have to be powered and have speaker level inputs and outputs in order to work properly with this amplifier. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.
