Dayton Audio DTA-2 Class T Digital Audio Amplifier Module
Dayton Audio DTA-2 Class T Digital Audio Amplifier Module is rated 4.5439 out of 5 by 57.
Rated 5 out of 5 by from Can not be beat for the price!Pushes my B652's very well in a boombox I made. Volume knob is a handy feature. The overall unit is very small. Its nice to have a small amp with a nice sensitive input. My Sansa MP3 player can drive this amp easily without having to peg the volume. I plan on buying more for other projects.

Rated 4 out of 5 by from great ampi build and sell speaker systems using cigar boxes as the enclosure, i used this amp in a 4 spk and 2 tweeter setup along with a external blue tooth and rechargeable battery it sounds great.

Rated 2 out of 5 by from Good little amp, but...This amp produces good sound, but it wants to amplify unwanted sounds too. I used the ferrite chokes and capacitors that were included as per directions. However, it is picking up some signal (perhaps from the Bluetooth receiver?) and it is very distracting! I'm going to enclose it in aluminum and/or remove the Bluetooth to see if that helps. If it works, I'll follow up.

Rated 5 out of 5 by from MoTo Sound that doesn't Tax electrical system!I've bought two of these units. For portable application and for the moto. And I know I'll buy more! I had been having troubles with using small commercially available car audio amplifiers in my Honda Pacific Coast 800 (PC800). Known issue with the bike is inability to add very much extra current draw in the way of electrical add-ons. After countless headaches, replacing a burnt Voltage Regulator/Rectifier, then upgrading to a MOSFET based R/R... and killing-off two moto batteries in the process... I decided to give this little guy a try, since some sound is better than no sound. I'm using an old Creative Labs ZEN Nano Plus MP3 player as input, but its input proved to be not quite strong enough so fed it into a FiiO E5 Headphone Amplifier that then feeds into the DTA2 which I built a small wooden enclosure for to fit in the "glovebox" in the front fairing of my moto. One thing I like about this setup is that I can control when the amp comes on via the rotary switch... so when I'm trying to crank-over the moto after it has set for a while I don't have the amp pulling a draw trying to sabotage getting her started. The output is pretty darn good! The bass is not quite as good as the other car audio amp I was using.. but the speakers I'm utilizing are Polk Audio db401's which are 91db Sensitivity so they get nicely loud with this setup. I'm very pleased that I now don't have to go without sound in my ride. And... you can run a DTA2 virtually all darn day at full volume off a 12v 5Ah battery, so now I don't have to worry about this little guy taxing my electrical system!

can i use 2 of these amps to power 2 Tymphany TC6FD02-04 2" Full-Range Line Array Driver 4 Ohm in a small portable box for my cell phone??

Asked by: gmo0428
Yes, but if you are only using two drivers you will only need one amplifier.

Would part# 142-0453 be suitable to power this amp? If not, could you tell me whuch part numbers would make a good portable power source for this amp?

Asked by: BFrishcosy31
I would not recommend using that battery for this amplifier. You would have better results with a sealed lead acid type like below.http://www.parts-express.com/power-sonic-ps-1220-sealed-lead-acid-battery-12v-25ah--140-360

I need to replace the LED on this unit. What is the closest part number LED to use in the PE catalog? Thanks

Do I need the capacitors between the speaker outputs?  I don't recall having them the last time I made a podzuma out of a dta-1.  

Asked by: Temoore55
They are not required but they are recommended.

Hi! I'm thinking of using this amplifier with a 12V battery. I couldn't find the output current of batteries anywhere. How can I be sure it is 2 A? For example if I have a 12VDC 20Ah AGM battery? Do i need to put something between the batt and the amp?

Asked by: Matti
The amp will only draw the current it requires. A 20Ah battery will theoretically last about 10 hours assuming the amp is being used at its full potential.

I have constructed a mini wooden enclosure for this amplifier module, and the parts inside are very tightly fit. The side with the capacitors is facing downwards. Should I be worried about heat issues? If so, any suggestions on how to fix it? 

Asked by: Mattk
This amplifier is very efficient so it produces very little heat, I would not be concerned about it.
