1x600W TAS5630 Class-D Amplifier Board
1x600W TAS5630 Class-D Amplifier Board is rated 4.3333 out of 5 by 3.
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

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.

amp not working well help?

hey I have this amp and a 24 VDC 6A 145W power supply ( I know a bit under powered but there should still be a good amout of sound) wired to a alpine type r (600rms ish) I am using the subpre out from my reciver and have all eqs and options set to boost the sound coming from the sub and it is extremely and not and "low" frequencies. I know improving the power suppy could fix it but I dotnhave the money for it. I also tried a 2x 100 watt amp and also got low low volumes. any advise or help would be great. thanks pat
Asked by: Patrick
First a few facts. The most power you can get from a 145 watt power supply would be 145 watts if it were 100% efficient. Since nothing is, let's assume you have a 100 watts to work with. Now the speaker. A 90 db speaker is twice as loud as a 80db speaker with the same amount of power. This is true for both amps and speakers, for every 10db it takes 10 times the power. So, to get twice as loud as 100 watts you will need 1000 watts. To get twice as loud as a 80 db 1 w@ 1 meter speaker you will need a 90db speaker. Bass boost will not help because the amp will quickly run out of power. When it comes to bass, cabinet size and placement in the room will make or break bass. 24v x 6 amps = 144 watts providing your voltage is not dropping as the load increase. Hope this helps.

Can this amp run off of batteries?

Was wondering if this amp would run off of a 48V 18Ah SLA battery created from 4x12V batteries wired in series.
Asked by: wdadams
Yes this can be powered with any 20-50VDC source.

Replacement part for Infinity TSS-1200 sub?

Can I use this board to replace a bad amp board in my Infinity TSS-1200 sub? Will it work with the existing power supply?
Asked by: MDC13
Unfortunately no, this is a stand alone amplifier board. You would be farther ahead replacing the whole plate amplifier.

This and PS only items needed?

Is this literally all that is needed or are there more parts (besides power supply) needed to assemble this and make it functional? How much assembly required?Obviously throwing it in a case of some sort is recommended but I am just curious if there are more parts to it?Thanks!
Asked by: sburnett
This and a power supply is all you need to make this amplifier work. You can always add on accessories but these are optional.
