2:44 but why do you edit the music instead of leaving the demo speakers to play music?? that board is not connected or not working or why? because its surely edited, the music starts before you press the button :D
I have a question if I was to go for that 600w two channel one and I’m using a 48v battery that has 30ah 500w. how long would that battery last me I can’t seem to be able to figure it out?
Hm my ampifier Wondom is for 300W 4 Ohm. The one you gave me in the article number is the single reel in it? It will handle the mini 300W mono Wondom amplifier?
I just picked up YAMAHA NS-A635A bookshelf speakers from a pawn shop and I am planning on making a suitcase boombox. It has 3-way system: 8" woofer, 4-1/2" midrange, 1" tweeter. 10W min to 140 Watts Max at 8 ohms. Which amp would you suggest?
Hi Alan, I forwarded your question to our tech department, and they responded with: "If the speaker is intended to be portable and battery powered, I would recommend something like the Dayton DTA2 in the link below. www.parts-express.com/dayton-audio-dta-2-class-t-digital-audio-amplifier-module--300-385" If need more information, you can contact them directly at tech@parts-express.com or by phone at 1-800-338-0531. Thanks for coming to Parts Express!
If I were to make a stereo system using amp boards, where would you place a headphone jack in the signal line? (the kind that would mute the speakers when plugged) .. I would guess after the preamp?
+Kyle Comeaux Yes, it would go after the preamp. However, it will most likely be a little more involved than just adding a headphone jack. I would recommend speaking with one of our technicians for more information. 1-800-338-0531
My subs in my Behringer eurolive B812 neo series stoped working but my tweeders still play this is powered by class D technology. I've been sitting on these with this problem for 6 months. What could the problem be?

Can you give me the link for that 6 channel d-class amp. I am going to make a proper 5.1 ch home theatre with optical input. Can you give me some suggestions, that would be great. Thanks
Yeah.... that's what you recorded of those speakers.... I love you guys. Why do you make those kinds of decisions? "Let's just edit in audio instead of allowing people to hear what the speakers sound like either miked or in the room." We're a bunch of audio freaks here, Man. Give us some credit.
As long as the power supply is regulated you can use a higher amperage adapter. Not a lower amperage. If your charging batteries it is best to stay as close to the amperage as possible.
It’s still recommended to buy a power supply higher than the max amperage of the board. If you do not plan on using the full power of the board you can go under amperage and be cautious. We will have two new power supplies coming out for 24 volts. One will handle 25 amps of current for $100, and the other will handle 41.7 amps for $200.
+Adam Elliott, you could power it with an RC battery, however a single 8.4 V would be insufficient for this amp. I would recommend at least an 18 V battery. You could also run two 8.4 V batteries in series for a total or 16.8 V.
basically divide the power rating by 2.5 to get a more accurate representation of how many watts you get. HOW IS THE FREQUENCY RESPONSE FOR THESE ?!? flat or wonky?

Yes, The Class D amp boards can be hooked up with a battery. Make sure the battery voltage is the same and the Amp Hour rating is long enough to hold based on the amperage you are going to pull. ie: 1AH battery will last one hour with one amp draw ( load)

witch one will work better for making a portable boombox this4x100W @ 4 Ohm TK2050 Class-D amp board or this one 4x100W TDA7498 Class-D amp board or if you guys know a amp that will work better will you let me know pls
i want to put one of these in a old car radio.I want it to have a knob style volume ,but i dont want it to be installed.I need it to be separated from the board cause i need the knob to go threw the origial car radio knob hole.i also would like it to have Aux input
This sounds really cool! If you want, call or email one of our techs and they can give you some suggestions on parts to use and possibly steps to take. Email: Tech@Parts-Express.com Phone: 1-800-338-0531

***** Are you sure? Because according to Sure's website it says the minimum is 10VDC. Well, I ordered it, we will see if it will work when it comes. I think I ordered it through you on Amazon. we are talking about the STA508 or TK2050 (According to the listing by you on Amazon it says the minimum recommended is 12VDC, so lets hope it works, because I don't have a power supply small enough for what I need it for than a 12V 12A power supply).
+Joshua's Recordings 12V = 12W RMS / 25W MAX / 50W PEAK at 1% THD / 100W PEAK at xx% THD.. For 100W RMS per channel = 95~105V. Observe the maximum voltage that the amplifier can accept.
You need a separate volume control. I can't speak to exactly what you are doing without details but this should work for you. Get the amp board 320-2240 with the volume control 320-3180 and power supply 120-055. Hope that helps.
if it has the volume on the amp then I could probably smolder the three wires to the three prong to the amp volume knob going directly to my stereo volume knob so I wouldn't have to use two knobs for volume, right?
Hmmm... Not too sure about the power handling capacity of the power connector and cable. Might be better to solder direct to the board. Just sayin.......
I want to buy the 4 Channel 100 watt but i want to use a accu then i can make a kind of speaker box that i can care whit me but witch power supplies i have to use that i can care whit me to use in me speaker box

So the '2 x 250W', at 90% efficiency, needs two 56V PSUs supplying 5A each through 2.5mm DC plugs? That's pushing it. I suspect the stated wattages are not RMS; the engineers' rating unit, in which a Marshall guitar head is 100W RMS and would blow these toys out of the water. This is car hifi numbers; peak music power output; inflated so boys can boast. And volume depends also on speaker efficiency.

Ok. Actually, I was referring to the power output ratings, like the 100w per channel amp. I just called them and found out that the amp output ratings are in 'Peak' watts, not RMS or average. Peak power output ratings are rather deceptive.
THD stands for "Total Harmonic Distortion". It is a measurement, usually given as a percentage, of the amount of distortion present in the signal that the audio equipment is producing.
how can the heatsink be so tiny? even if the eficiency of the amp is 95 percent you still need to get rid of a lot of watts of power. That little heat sink looks to tiny and i bet the amp would be death very quickly
Efficiency is everything. Say you have a 100w class D amp at 90% efficiency. Only 10% of the power is wasted/dissipated in the heat sink, which is only 10w, which is really nothing. The other 90% of the power is dissipated in the speaker as heat and sound. I'm surprised they included fans on these amps, totally unnecessary. A laptop CPU typically needs to dissipate 30w, and the heatsink is absolutely tiny.
The amp would need to be given the right input from the preamp source and it will provide the output desired. So for a proper 5.1 channel setup it would need a preamp that can decode the 5.1 signal properly and then provide that to the board for it to reproduce a 5.1 output.
Josh Maiura , five plus one equals 6. did you go to school ? in other words............ 4 stereo full range channels plus one "Mono" channel is / 6. get it ? 5.1 or 6 channel math is the same all over the world, at least that's what I learned in kindergarten, lol.
You can split your preamp signal to supply several amps with an input source. Those can then drive separate speakers. But you cannot add several amps to one speaker or set of speakers. It runs the risk of damaging all of the equipment involved.
, No volume control knob, no tone control knobs, no balance or fader control knobs, so how the FUCK are you supposed to control anything ????? someone please answer that for me
