Dayton T-amp module. Anyone tried it out?

[analogger]

I just put in an order, but realistically I need another project like I need a hole in the head. Wondering if these perform identically to the standard t amp. I have a ghetto blaster idea I've been wanting to try. DVC sub with one module, another to drive mains... Thoughts? I've heard they do not drive infrabass, but seems a DVC or pair of subs around 8" can't hurt...

Also makes me think of my remote surround sound 5 channel system.... soooo many ideas.....!:D

Are you referring to the DTA-1 or the DTA-2?

Although I guess it doesn't really matter which.

Wow! I have not seen the DTA-2 before. I have been contemplating a simple 2 way with an active crossover with the DTA-1. With the DTA-2, it comes already taken apart, and is certainly more affordable. It is possible that the crossover could be just passive elements before the input of the DTA-2. (Unfortunately, it may be sometime before I can start this project.)

I have one of the original style Sonic Impact amps. I can't confirm, but IIRC the circuit board look the same as my T-amp. My experience is that it was sounded pretty good, especially clear for loud treble, much better than I expected from class D. I thought very low level signals were a little muddy, but overall the SQ was still worth the price. It is limited on the voltage range, so it will work better with 4 ohm speakers with higher voltage sensitivity. (Also by going active you eliminate the losses in the crossovers.) Also unfortunately, the input jack (on mine) was PCB mounted and quickly broke away from the traces. Another reason why I will be going the more DIY approach with the DTA-2.

Analogger: Your idea for a blaster is right on. This is the most efficient way to make some sound. You might consider two satellites with 4 ohm drivers (tweeter and mid-woofer) with an amp on each. Then a third amp driving a dual voice coil sub with two 4 ohm coils (car audio stuff).

Fair disclosure: I don't listen very loud. They can play "TV loud" in a medium room. But don't expect any kind of Home Theater or Concert loudness.

I have one of the original style Sonic Impact amps. Same circuit I believe. (You can find a great deal of on-line comments and mods for the Sonic Impact amps.)

It almost seems like they are hiding it. I don't even remember where I originally saw it, but I haven't really found any threads on any forums discussing it. I had to search for it on the PE site, as Google didn't seem to find it.

I'm definitely going to be picking up some of them for ipod-based projects and other near-filed applications.

I've heard they do not drive infrabass,

Reading from t-amp posts, the problem with bass is the amps use a blocking cap (2uF?). I think the bass rolloff problem would go away with a larger cap (maybe 10 uF). I would use a film cap. If you really want to go infrabass, then you would need to remove the cap altogether and either "level shift the input" or "create a virtual ground" (for the input signal). Then the amp could be fully DC coupled.


Hempy: Great Find!

Re: Dayton T-amp module. Anyone tried it out?

Would be an idea to go dig up the sites that had T-amp mods... There was one guy in Hawaii that had one of the best... lots of testing, scope shots, etc.

He had the schematics there, and info on what to change out for the inputs. As I recall, a standard T-amp rolls off pretty fast around 30hz.

Different line of thought, maybe that's not a bad thing for small speakers, or even a small desktop sub...

I've been thinking about a few projects along these lines too...

Are you thinking of Michael Mardis (Panomaniac)?

Re: Dayton T-amp module. Anyone tried it out?

those single units would be cool used for the amps for the mids and tops in a 3-way. Use a D-class plate or something like the Dayton SA70 for the bass, pretty cheap way of going active !!

Re: Dayton T-amp module. Anyone tried it out?

Does anyone have a good source for the required power supply?

I would definitely consider an active project built around a pair of DTa2, one left and one right.

I wish I'd seen this http://www.parts-express.com/pe/show...TOKEN=80491922 before I bought and tore apart the nicely packaged one.

Does the module come with the large ferite beads and caps on the speaker outputs?

Man, I've been looking for weeks for cheap switching psus, and I couldn't get under 10 with shipping. Nice find!

Group buy, to save on shipping?

EDIT: Free shipping? I didn't see free shipping.

Re: Dayton T-amp module. Anyone tried it out?

I see the power connection and 3mm (or whatever) input connections, as well as the cable to the volume control.

Where are the connections to speaker-level outs?

I'm guessing they are just traces on the board or maybe there is a pinout/female plug somewhere on the board (maybe underside?)
