1x600W TAS5630 Class-D Amplifier Board is rated 4.5 out of 5 by 4.
Rated 5 out of 5 by from Awesome Bass Guitar Amp!After about a year of playing thru this amp board, all's I can say is WOW! With Or without a pedal, this really delivers deep tight bass, my low B string really growls and with 2 ohm stability, you don't have to worry about hooking up two 4 ohm cabs! Be sure that your power supply can deliver the current to run 600 watts. Another real nice feature is the gain settings. You can zero it in for passive pickups that I tend to use, very nicely. You can't go wrong for the price!

Rated 4 out of 5 by from Pretty good, but quality could be betterWell, this is one of those not sure if it is worth it purchases when I originally bought it. Because the specs were great for a 4-8Ohm load, I decided to go for it. I've had good experiences with Class-D amps in the past.For this project, I created two 15A 24V power supplies (which I then adjusted to 24.95V each) and put them in series to create a 49.9V linearly regulated power supply. The end result wasn't entirely astonishing in terms of noise, but it served its purpose, especially since it ended up costing me a little less than the 48V switching power supply listed on PE. Besides, it’s a great learning experience, even though the design can be way better. Maybe someone with more EE background can chime in with some suggestions.I have two amps total powering two speaker at 4ohms. The speakers are a 2.5 way using two 8ohm drivers in parallel and a 6 ohm tweeter, thus the 4 ohm rating I gave it. Before, it was being powered by a Rotel RB-1072 (Also Class-D with a switching power supply, rated at 100W RMS) with very good results. As a note, even though the Rotel's datasheet mentioned it does well with a 4 Ohm load, it's a load of bull. The distortion profile on such a load was too horrible to stand, so I used a 2:1 transformer (namely the Dayton in-wall speaker volume control) to double the apparent impedance to 8 Ohm.With the previous set up, the frequency response was very flat, and the detail and transparency was very much top notch. The sound that came out made it sound like you were in the recording studio with the artist during the recording session. It is pretty amazing. Of course, it could be better. The highs were a bit lacking in punch, and the volume couldn't go quite too loud, as distortion became a major issue at > 90 dB.Now for the new amp with the same setup. Initially, it went through the same 2:1 transformer. I reset the transformer to 1:1, and the sound didn't change. That's good. This amp truly has a similar distortion profile with either impedance. I turned it up, and the distortion remained pretty much the same all the way to unbearable levels. Even better. But unfortunately, that's where the fun stopped. No matter what volume, the mids were recessed, sibilance were unnaturally nonexistent, and cymbals from a drum sounded like white noise in the background. Overall, it was clear that this TI chip cannot possibly outperform the Rotel ($1000 new) at all quality-wise no matter what kind of thought was put into the design. Quite sad. Detail's not quite there, and I detect some more distortion than the RotelI got an idea, though. I have a BBE sound maximizer on the same rack, so I turned it on and tuned it to increase the high end (3/10) and bass (1/10) a little bit. That brought the life back into the amp. The level of detail still isn't quite there, but it finally started to sound much more like the Rotel, to the point where I don't regret retiring it from its current duties. When I switched the output to my computer speakers, those then became unbearable. Turning off the audio processing did the trick. I am not sure why this amp is behaving in such a way as to distort the sound that greatly with phasing issues, but it is something that needs to be addressed.One thing I am thinking of doing is to replace all the power caps (7 of them) with higher quality caps. Also, I would like to remove the switching 12v power supply on the amp with a linearly regulated 12v just to see if that would make a difference. That particular circuit on the board feeds the fan, the logic circuit on the TI chip, and the input inverter chip. The last thing I mentioned is what I hope can benefit from the switch to linear. We'll see what happens.Overall, I can't complain. I'm comparing what ended up costing me 2x $250 with an amp that costs double that when new. If you compare a 200W per channel RMS amp with any other stereo amp in the $500 range, it will definitely be tough to beat. Just don't expect to get the same bang/buck you would get by DIY'ing your own speakers. That is not to say don't do it. Just don't expect much. I have learned far more from this experience than I would have if I didn't take the plunge. I don't regret it.

Rated 4 out of 5 by from Solid, with caveatsI ran this up to 50W into a dummy load. I checked the frequency response and the radiated interference.Out of the audio band, at about 67kHz there is a huge spike in the frequency response. You need to be sure than you band limit the input so you have at least 40dB attenuation at 67KHz otherwise bad things are likely to happen.The non calibrated EMI test set up did not show any concerns but I recommend that you make a turn or two of the speaker wires through a ferrite to suppress any common mode HF noise.One last point, on assembly quality, the input RCA connector on the sample was broken.

Rated 5 out of 5 by from Just waiting to be unleashedI bought this amp for use as a sub woofer driver. I have only tested this on the bench. Awesome this baby is ready to spank the daylights out of Legacy Preditor 15" sub. Honestly I personally like the sound quality of the Tripath amps, but this amp is right up there with them. Well worth the cost for a cool running high powered amp of this stature.

1x600W TAS5630 Class-D Amplifier Board

Hi, I have an sitting-unused SE-350-24 (24V, 14.6A) power supply that I would like to use with this amp. I'm guessing it would only drive the amp to about 50% of potential, but is that the only downside? Or would there be other issuesl? Thanks, Todd

Asked by: toddmargo

Is it just my board that has a very hot U4? (bottom right corner of the board when the RCA input jack is at the bottom) Mine measured 230f ! with a infrared thermometer.

Asked by: Carl P
To update my question, U4 released smoke about a week of use. So nobody else has had this problem? Did I get a bad board? I sent an email to sure electronics customer service about this.

could this be a good driver for coaxial speaker 8" 250w min to 500W or two i need to separate amps.

Asked by: en76
This should be plenty for a single 250 watt speaker.

Looking to power this AMP of a pair of Small 12v Batteries in series (24v) feeding a Eminence PXB3:3K5 (PN# 290-652) and speakers TBD for a portable, loud PA type Sound System. Looking for Sanity Check and a way to calculate AH needed in Batts.

Asked by: brittonv
Working on something similar, so I'll try to give you an answer.  In the end, this will depend a lot on your speaker choice.  The TAS5630 (chip in this amp, assuming PBTL config) datasheet claims about 80W output at 25V (4 ohm speakers, 10% THD).  I'm going to extrapolate from the BTL graphs that it's going to be around 65W unclipped and 85% efficiency.  So we have a max power consumption of 75-80W playing at a clean 65W.  At 25V, that's around a 3A draw.  In a perfect world, a 24V (12V + 12V in series) 3Ah battery is going to get you about an hour of play at full unclipped volume with 4 ohm speakers.  Turn it down and battery life goes up, of course.Good luck!

I'd like to use this to replace a fried amp board for a subwoofer. The subwoofer specs are • Power handling: 150 watts RMS/475 watts peak • Impedance: 8 ohms • Frequency response: 25 - 200 Hz • SPL: 90 dB • Would this amp board fit the bill? 

Asked by: mwagz
Unfortunately this amp board is not designed to replace a bad amplifier board in a stock subwoofer. I would recommend finding a subwoofer plate amplifier for this purpose.

Hi I have two subs both SVC 250@4ohm. Should I use this or 320-309?

Asked by: RAVI73
Either amplifier will provide the same amount of power although the two channel version will have half the distortion.
