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.

What are the RMS ratings of these amps I need at least 120W/ch RMS

Asked by: stephenopolus
According to the specifications you should achieve the 120 watts you are asking for as long as you have sufficient power supply. Formula is; (amps times volts = watts). You must have about 15% more available watts coming from your power supply than you expect to get from the amp since there is loss in the conversion. A power supply of 50v x 14amps = 700 watts. Which is about right to get the advertised 600 watts back. One thing to remember is 10% distortion = 50% of the volume is distortion. Why is that? A 10db increase in volume is perceived to be twice as loud to the human ear. It takes 10x the power to raise the db level 10db. or twice as loud. So 10% of 600 watts is 60 watts which is half the volume because to be twice as loud as 60 watts it takes 600 watts. Therefor 10% distortion is half of the volume. That is nasty, however 200 watts @ .4% in a sub is tolerable. As far as RMS, it could be rated as RMS because power in is less than power out. If it were rated at 600 watts and required a 2amp fuse at 50volts there there would only be 100 available watts if it were 100% efficient. Then the watt rating would be PEP (Peek envelope Power) which is total hogwash and means nothing. You will find that in a lot of car amplifiers where they claim 2000 watts and require a 10amp fuse. That is PEP since the most power coming in is about 140watts. Hope this helps, LCAdvertised specificationsPower output (w/ 50 VDC power supply): 600W x 1 (2 ohms, THD 10%), 300W x 1 (4 ohms, THD 10%), 200W x 1 (8 ohms, THD 0.4%)• Minimum impedance: 2 ohms• Frequency response: 20 to 20,000 Hz (±3 dB)• Recommended power supply: 20 to 50 VDC, 14A regulated• Fixed gain settings: 23 dB, 29 dB, 33 dB, 35 dB• Power input jack: 2.1 x 5.5 mm, center-positive• Dimensions: 6" L x 4.7" W x 2.1" H

Would an Avel Y236852 be capable of powering two of these boards?

I am planning on doing mono-blocks for a stereo setup with these boards. It is difficult to find an SMPS at a good price point that matches the recommended power requirements of the board (20-50V @ 14A), so it came to mind to use a toroidal transformer. The Y236852 is spec'd to provide 2x35V at 9A. Rectified, that would be right around the 50V mark. Would this be sufficient to power two of these boards, one from each secondary? They would have independent rectification and filter sections, if that matters.
Asked by: blairfrischx
I have been doing some research on linear power supply design and construction. In fact, using this transformer in a full wave rectified (center tap as ground) would indeed yield about 50V RMS at 9A or 450 W. The answer to your question depends on the impedance of the speakers you intend to drive. Since the amplifier will produce 150 W RMS at 8 ohms, yes, you could probably run 2 boards using one 625 VA transformer. At a lower impedance (4 or 2 ohms) you would need one transformer per board. Building a high current 50VDC regulated linear power supply is not a project for the novice or the faint hearted. You will need to implement a more complicated regulator topology than is needed at lower voltages, with plenty of heat sinking. Also, you would probably not get a full 50V regulated but would lose 3-5V DC from diode and regulator losses. However, the effects of these losses on your eventual results will not be audible. Using two of these amp boards as monoblocks into any reasonably efficient speaker system will be HIGHLY audible, probably at great distances, until you vaporize the speakers, or, if your neighbors do not like your taste in music, until the police arrive.

How would this work as a bass guitar amp? I have a stand alone pre-amp that handles all the processing, just need a power amp.

Asked by: ccreddell
This board would make one incredibly powerful bass guitar amp--perfect for projecting rock music from the earth to the moon (I exaggerate slightly). Just don't vaporize your speaker(s)!

Which accessory to use to control Volume?

Which of your other parts to use? 50k POT? 100k POT? does this control board also work?
Asked by: markhirsch
I have found that either 50K or 100K pots work nicely as input volume controls for this class of amplifier.Given that this is a MONSTER amplifier board, a whip and a chair might also be helpful, also maybe seismic foundation braces for your house ;).

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.

can this be used for subwoofer plate amp? Is the fan smart control?

I have a blown subwoofer amp with good torroidal power supply 42.5 volts. Would I need a power regulator board or is the transformer enough?
Asked by: DiscoDuck
Hooking up this amp to the toroidal power supply should work just fine. It won't quite be able to deliver 600W (you'd need a 50V supply to do that; the lower the supply voltage, the lower the power output), but it'll be pretty close. So no, you wouldn't need a regulator. Just make sure the transformer is powerful enough to handle this 600W amp, which I'm guessing it would be if it was already powering a plate amp.As for the fan, I don't know about this particular amplifier, but I do know that the 4x100W Sure amplifier that has the built-in fan is not smart control: it's just always on. It's virtually silent though, so you'll probably never hear it.
