Dayton Audio DTA-2 Class T Digital Audio Amplifier Module
Dayton Audio DTA-2 Class T Digital Audio Amplifier Module is rated 4.5161 out of 5 by 62.
Rated 5 out of 5 by from best purchaseI bought a bunch of these when they first came out on sale and built different things around them. First was a small box that I put 2 extra car speakers I had which were 4" coax, and that is used in the garage and sounds pretty good. Another was put in a small jewel box I got at a craft store and that could get hooked up to anything since it's easily portable.The 3rd and most often used was I got a nice cigar box and put 2 of these amps in and set it up so that one drives speakers in my living room while the other drives the ceiling speakers in my kitchen. The sound is great, I can't turn them up past 3/4 because it is too loud unless you're having a house party. When people hear it for the first time nobody believes me that they are only 15 watts because you wouldn't know.I don't remember exactly when I got them but it has been a couple of years and haven't had any problems so far. The 2 in the cigar box are used every day. So they seem well built.

Rated 5 out of 5 by from Very nice kitThis is a very nice, small amp, and the sound is terrific. The components seem to be of good quality, so far. The biggest issue I ran into was space constraints, and by cramming all the wires into a small compartment I accidentally unlodged the power connection ribbon - or I never lodged it correctly in the first place. Don't have to be gentle with this amp. I gutted a pair of the Philips 314113000201 R TMM 2-Ways and built a small set of desktop speakers. Would change the design if I had to do it again, but the amp is more than adequate. I think the sound is better than from the same speakers in their original housing being sourced by a Lepai, but there's some bias after pouring some sweat into these.

Rated 5 out of 5 by from Works great. First real amp/speaker projectI used this to convert a tube am radio using this and the SD/USB mini kit. Everything is working great!

Rated 5 out of 5 by from Worked perfectlyBuilt the rock n dock for two of my grandsons and they performed perfectly. They will both enjoy the sound at Christmas

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.

Dayton Audio DTA-2 Class T Digital Audio Amplifier Module

I need to know, can I connect a microphone to this amplifier? If so, do you have any microphone to suggest for this product? Thanks.

Asked by: Ali rahimi

I would like to wire additional LEDs from the power LED to light up the faceplate of an old radio and need to know what resistor to use.  Does the power LED get 12V from the board?  Or is it 5V?

Asked by: NathanA
The voltage source for the LED will be stepped down from 12V although I do not know the supply voltage of the LED itself. You can test the output with a voltmeter to determine the amount of power being fed to the LED.

What is max power to 4 ohm speaker

Asked by: wayn
We only have RMS power published for this amplifier, we do not have max power ratings available.

Can RCA inputs be added to this amp? If so, can I still retain the 3.5mm input also? Thanks.

Asked by: awash242
This amp is not intended to have anything added to it or modified. You could use an RCA to 3.5mm adapter to plug into it, but you would not be able to retain the 3.5mm input.

"Recommended power supply: 12 VDC, 2000mA, regulated." - will it work with a lower voltage source, such as a 4.8V, 4Ah battery pack?

Asked by: woodscraps
No, this amplifier will only work with 12VDC.

Also, can someone tell me what the correct coax plug for the jack on the PCB (is it 2.1 x 5.5)?

Asked by: TIM 7
The plug is 2.5 x 5.5, tip positive.
