4x100W at 4 Ohm TK2050 Class-T Digital Audio Amplifier Board

Based on two TC2000 and four TP2050 chips from Tripath, this Class-T audio amplifier board simplifies the creation of exceptional sounding custom multi-channel systems. Compatible with power supplies ranging from 10V DC to 30V DC, it can be used in many audio applications. The amplifier has four channels with the same power of up to 100 watts each, resulting in outstanding sound quality and versatility. You can employ any number of channels you like, and leave the others unused.

This amplifier is exceptionally well designed, with a lot of power reserve, high fidelity, low distortion, good S/N ratio, high sensitivity, and full protection with heatsink and fan. These ideal characteristics make this amplifier a candidate to become the basic building block of your future high fidelity system, or it can become the element that will upgrade an existing system.

4x100W at 4 Ohm TK2050 Class-T Digital Audio Amplifier Board
4x100W at 4 Ohm TK2050 Class-T Digital Audio Amplifier Board is rated 4.3333 out of 5 by 6.
Rated 5 out of 5 by from Very good amp for the priceI have two driving large open baffle speakers. I checked the datasheets before buying these. At the rated 100W per channel THD is just over 5%. At 70W they are at 0.005%! They sound great. I will be using them a lot.

Rated 5 out of 5 by from These amps are all so great. This is no exceptionThis product, just like all the Sure Amp Boards, works great, has next to no distortion and easily embeds in audio projects. I have put this thing in countless custom projects and the new owners are always blown away. Sometimes, I put these right in speaker cabinets I've restored or build, with a BlueTooth unit to create an almost wireless sound system. People LOVE it.

Rated 3 out of 5 by from Didn't work in the car. Worked fine on the computer.The amp picked up way too much noise to be used in the car. I spent all day with no success trying to get it grounded enough to stop the noise even ran a ground directly to the battery. Put the amp in different locations and ended up using a regular auto amp instead with no problems. Not sure if there is a filter or something that would allow it to be used in the car since the directions say it can be used for auto. I hooked it up to a 12 volt and then a 24 volt power supply to a laptop in the house and it sounds good with either power supply with no background noise.

Rated 5 out of 5 by from Wish I had this decades ago!Got this to drive a multi-speaker basement setup: 2 Bose 301 Series II, 2 Realistic rear mini speakers, 2 large Utah bookshelf speakers (and eventually 2 AR-4 speakers, once I re-cone them). I wanted to see how much current it was taking since the power supply (24VDC, 14.6A, Part #: 320-316) fan was not running. At idle, it took 0.37A. At too loud for upstairs TV watchers, it took 0.4A. I measured it with 2 different meters. Since my power supply would only go to 27.4V, that is 10.96W input power. So it is loafing, with lots of head room, and sounding very good! I drove it with a McIntosh C27 preamp.I wish I had this amp decades ago when I was providing the sound for a parade float for a children's chorus. It would have sounded far better than what I had then and it would have run on batteries (even 2 x 12V lawn tractor ones would have lasted the duration of the parade). And it would sound far better than the typical float "boom box" setup.This amp would also have been excellent for providing the sound for a Jr High musical in a sound challenged cafeteria-auditorium. The individual channels would have allowed adding the proper delay between the front audience speakers and the middle audience speakers, or for adding individual channel echo-canceling signal processing.

Rated 5 out of 5 by from Wow, it sounds better than expected!Giving it a rectified 25VDC from a salvaged pwr supply, The sound quality is much higher than anticipated. The onboard fan was initially a concern, but remains mechanically and electrically silent. I have not tried to clip this amp, but have driven it fairly hard and it delivers the goods. The turn off thump is also quiet enough to completely dismiss. There is no power-up pop. The power jack seems to be an oddball size, which required me soldering directly to the board (no biggie). Overall, definitely a deal.

Rated 3 out of 5 by from 50% reliability, and missing some features.I recently purchased two of these amps to run 6 Aura Pro tactile transducers + 4 Dayton "Pucks". One amp is running four Aura Pros, the 2nd amp is running 2 Aura Pros (4 ohms each) and 4 Dayton pucks (16 ohms each), two per remaining channel in series, so that amp is running two channels at 4 ohms, and two at 8 ohms. But the 2nd amp whose channels I plan to run at 8 ohms were not working....after troubleshooting a bit, I found the channels are indeed dead. So I'll be replacing the 2nd amp.I'd also mention that the recommended Mean Well amp does not come with a power connection required for this amp, and despite what the manual says, there is not a terminal block for the power input for this amp. So be sure you order part #090-492 to go along with this amp. I simply soldered my power connections for the time being.

4x100W at 4 Ohm TK2050 Class-T Digital Audio Amplifier Board

can this amp be use for a DIY project (Portable Boom Box) and if so what rechargeable battery do you recommend

Asked by: antonio229
This can work from 10 to 30volts so a battery is possible. The main obstacle would be the required amp rating. at 12 volts you would need over 30 amps and that would be a very large and heavy battery.

do these amp boards need a heat sink?

Asked by: freddy1hound
Yes these do require a heat sink and air circulation in order not to be thermally damaged.

I want to run 2 pairs of 8 ohm speakers from my multi-zone receiver, whose outputs must go thru a separate amp (this TK2050) to power the speakers. One spkr set has about 30 feet of wire to travel through. Need recos for making sure this will work well.

Asked by: keithm
Yes this will be fine. a 30 foot run for speaker or signal wire is not a problem at all.

Hi there, reading manual I'll need 50k ohm potentiometer for volume. Will this suffice and is it all I need between source and Amp? Thanks https://www.parts-express.com/50k-ohm-potentiometer--023-550

Asked by: FuzzyEllis
Technically that will work although it will only control one channel. You will need a stereo pot in order to control both channels at once, unfortunately we do not have any 50k ohm stereo pots available.

Could i use L&R channels in stereo and bridge the other 2 channels to drive a sub in mono?
