the pictures show caps and ferrite cores - can you tell me where they go and can you post the datasheet? Thank you!
Each speaker output gets wrapped around each ferrite core, and the caps are wired in parallel to the outputs as well. The manual is available in the PDF below.www.parts-express.com/pedocs/manuals/300-385-dayton-audio-dta-2-manual-43360.pdf

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??
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?
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

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.
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?
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?
This amplifier is very efficient so it produces very little heat, I would not be concerned about it.

Is this amp bridge-able? I'd like to build a mono 2 way portable boombox powering one dayton nd105-4 (Maybe a 50 hz hp xover?) and a ND20FB-4. Both 4 ohm. Thanks!
Unfortunately no, this is not bridgeable.

is this plug 'n' play or is there a lot of soldering involved in this little guy?
This is a little bit of both. You will have to solder the speaker wires to the board, but otherwise everything else plugs into certain jacks.

I have a project that only needs a single full-range amp. Is it possible to run a single speaker off of this amp or perhaps bridge it? Or perhaps there's something else that you offer that might fit the bill.
Unfortunately you cannot bridge this amplifier although running one channel will not hurt it.

i want to use this amp in a small boombox and would like to use a rechargeable battery pack what type of battery and or specs would be possible to use with this amp?
Any 12 volt battery will work with this amplifier module. I usually recommend a sealed lead acid type, usually 2Ah or more. The higher the amp-hour rating, the longer it will last. This can be recharged with our float charger, part number 365-008.

Has anyone who has used this unit actually used any form of ESD protection, as in anti-static mats or wrist bands..? I received this unit yesterday but have put off un-baging it as I don't have either of these things; I'm considering just maintaining contact with a guitar amp chassis I know to be earthed while assembling.. :PI've read of people in the computer maintenance business dismissing ESD protection as paranoia and claim to have been servicing machines for years without using a wrist band and never having a problem; if one was to use a wrist band with this unit, how can you be sure that earthing yourself puts you at the same potential as the unit? Is it simply a given that items distributed in anti-static bags are at zero volts?Any light that may be shed on this controversial topic would be of great interest, thanks!
This amplifier is run using a 12 volt power supply. After it's unplugged, it only takes a short time for the capacitors in the power supply/amplifier section to discharge. When I service large amplifiers with huge blocking caps, I wait a few minutes after unplugging, then short the caps with an insulated wire. You won't need to do that here as this will drain pretty fast. You can wrap a simple copper band on your wrist or ankle, then run a "drain wire" to the nearest ground [cold water pipe/romex/]-anything that you are sure is linked to the house's earth ground and is solid. A 12 ga. wire will work fine. I don't see safety as "paranoia". While I've never been zapped--I know of others who have. Anyway, I assure you that this amp has safety in mind and you will be just fine. Try grounding your guitar to the same ground till this amp is enclosed. Good luck on a cool project!!

Could I use one channel of this as a small bass guitar amp or would I need to build a preamp for the input?
I would like to put this in a little 6x9 4 ohm automotive speaker enclosure and use it as a portable bass amp. Would I need to build a preamp?
Yes, this amps input is designed for line level signals. Your bass guitar pickup(s) are a fraction of the input required. You also wouldn't have any signal control, such as tone. There are a few stomp boxes on the market that would increase your signal sufficiently.

Use as a booster amp for car stereo AUX input?
Could this be used as a 'booster' amp - input from on iPod etc., with the output(s) driving the AUX input of a car stereo? What are the impedance-matching implications here? Thanks.
Unfortunately this is not a proper amp for this application. This uses a speaker level output and would likely fry the AUX input if you were to use it for such a thing. Usually you want to use a headphone amplifier or line driver to boost a line level signal like this.

8 or 4ohms? wattage? power supply for max output? will any of these knobs fit?
4 or 8 ohm is fine. 15W @ 4ohm and 10W @ 8ohm. recommend a 2A 12vdc power supply (like Part #:120-052) and both of those knobs will work :-)

Anyone used one of these as a compact guitar amp. I'd like to build an amplifier for acoustic guitar so little to no distortion is preferred. I'd also like to add a mic input, maybe guitar on one channel, microphone on the other(?)Any thoughts.Thanks!
Hello,You could use this amp for a small guitar speaker. A couple of pointers:1. I'd use 4 ohm speakers. Probably one on each channel.2. You HAVE to drive the amp from an active source (mixer, mic preamp, etc.). It has low input impedance--around 10K ohms. You can't just hook up a passive guitar pickup and expect good results. Sounds like your guitar is acoustic, so I'm assuming the pickup is active, so it probably will have low Z output. Make sure the output Z is less than 1k ohms.With those considerations taken into account, the Tripath amps work great for portable guitar amps. They are small and are very easy on batteries.If I were to use a setup like yours I'd set up a small mixer with XLR in for my mic and with a standard TS connector for my guitar. Use the mixer RCA output to drive the amplifier with two separate 4 ohm pa speakers. You don't need distortion, so there isn't really a need to have a special guitar amp speaker (make sure the PA speakers can go as low as about 60 hertz for the low E on your guitar). PA speakers are good mates for this amp since they are so efficient.If you are interested in ever going electric, build some boxes for 10 or 12 inch guitar speakers. Get a high efficiency speaker (like 100db/1W or greater). My Telecaster screams with my Tripath amp and a nice Jensen Mod speaker.Good luck and enjoy!

Does anyone know if there is a possibility to pull 5v from any place of this amplifier? or 3.6v? I need to power a bluetooth module
Pin 1 of the TA2024 is a 5V regulated output for supply to itself, but the datasheet I found doesn't specify how much current is available. You can certainly try powering your Bluetooth module off of that pin, but I wouldn't guarantee that it won't damage the amplifier.

2.5mm or 2.1mm 12v AC Adapter?
I looked through the questions and didn't see an answer, what size is the AC adapter jack on the board, 2.5mm or 2.1mm? Thanks in advance for your time.
This uses a 2.1mm power jack.

About to use every resource this little guy has... I think. Help with power stuff?
I have put together a bunch of these for various uses and the uses of friends and family. Love this little guy.I have hooked it up with A/C, and the 8AA battery clip thing.I am about to make a portable player for a friend's teenage son. I am going to put it inside an enclosure with some full range speakers. He'll use his iPod to play it through a 3.5mm jack I'll install on the enclosure.He wants it to be battery powered and A/C powered. I think there is a way to do this, but am unsure. How do I do this- that's question 1.Question 2. I think I can also charge the ipod with this unit. Is that right? How?And #3. If I were to buy one of those sealed acid batteries, like I have seen other people use in the project gallery, in conjunction with this device, can I wire it so it plays when unplugged off battery and plays + charges battery when plugged in?Thanks!
I have run this same scenario through my head, as I love these amps and have built them into a number of projects.My solution to power the amp with both a battery as well as a plug in power supply (AC-DC) is to simply use a DPDT center off switch. Switch it one way to power off the battery, the other way to run off household AC through your plug in power supply. The center off allows you to turn it on and off without using the volume knob, which is nice if you usually use it at a particular volume setting as I often do. This is not only the simplest solution I have come up with, but also the cheapest. Amico makes a perfect candidate for this switch and can be found on Amazon. I buy them buy the 10 pack. Note that you will have to wire the battery separately from the wall adapter through the switch...if this doesn't sound fun you can also just simplify and attach a barrel plug the the batter pack and swap it with the wall power supply plug as necessary. Connect a 335-372 barrel plug to your battery, whether it be a 8xAA or a 12v sealed lead acid and just leave the wire hanging out the back of the enclosure for portable use.To charge and ipod you will need 5v at 1 amp to a USB connector. You can wire a 7805 +5V Voltage Regulator TO-220 directly to the power input on the amplifier which will step down the voltage from 12v to 5v. Just wire it to a USB connector mounted in the enclosure.Third question...yes you can wire it to charge the battery while it is plugged in but you are getting into something a little trickier here. I have not actually tried this yet, only thought it out (because I have been wanting to do exactly what you speak of...just haven't tried it yet). You need something that will feed the battery power without over-charging it and thereby degrading it's life span (or even destroying it) and at the same time not drawing too much power off of the AC power supply. (To do this you may need a higher amperage AC/DC power supply.) Maybe a cheap trickle charger? I am leaning towards a charging circuit that cuts the power charging the battery when it reaches a designated voltage...but I am yet to diagram one out. If you really want to take it this far look around on the web for a 12v charging circuit and ask around with any questions you may have.. lots of people on the web are helpful in my experience. That is my plan when I get around to it.Have fun with your project, these little amps are just great.

Neat little amp but I am not sure how to wire the LED. The instructions say to solder the LED to the PCB at point D - yet point D is occupied on mine by a plastic connector (as I see in a number of the product photos), to which an accompanying wire connects. Assuming they simplified the design since the instructions where written and this is indeed where the LED goes I temporarily connected to this wire to the LED (and the unit is on) the LED does not work. Can someone assist me in understanding this?
The kit comes with a small wire pigtail that plugs into the small white connector on the amp board. The LED plugs into the other end of this pigtail. If the unit is on and the LED does not come on, flip the leads on the LED and try again, the polarity is probably backwards.

How can I add FM Tuner?
How can I add an FM tuner to this amp?I can't find a separate tuner board or kit here.I want to make a portable radio/amp out of a used mini keg can.
You will have to use an external tuner that has a line level output in order to plug it into the module's 3.5mm input.

This thing runs hot. Am I damaging it?
I've used this in a few boombox builds and am very impressed with its output, clarity and reliability. I've noticed that the TA2024 chip gets hot enough to burn fingers when it's running at max volume. Is this okay for the chip or should I put a heat sink on it?
You are probably only doing slight heat wear, that will lower it's projected life span, but nothing that should fail catastrophically. I personally, just bought an 8 peice chipset heatsink set, with 1x1.5 cm aluminum sinks and pre-applied heat goo, and used one on each board I have. Total cost was like $9 from some Chinese import website, and no more heat issues. Probably will increase your projected board life by ~40-50%, or atleast I hope it will. Best of luck fitting those little heat sinks to your boom boxes!

Would this external battery power this amp?
I have a 12v 5ah sla battery but its kinda big. Was wandering if a Anker astro3 10000mah external battery pack would work says it is switchable between 9/v/12v? Here is some specs from amazon.Astro3 Spec:-- Input: 12 V / 1A-- Output: DC 9V / 12V 2A, 2 x USB 5V 2A (dual charge @ 2A Max)-- Minimum required current: 80mAh-- Size: 4.9 x 2.9 x 0.9 inches; Weight: 10.2 ounce-- 18 months warranty
That looks like it would be able to power the amplifier with no problem.

If i connect a 12v battery to the terminals on the board will plugging in a power supply charge the battery? Is there any way to do that?
Unfortunately no, the power supply is only designed to power the amplifier and could damage a battery if plugged into one.
