Sure Electronics 4x100W at 4 Ohm Class D Digital Audio Amplifier Board STA508 (TK2050)
Sure Electronics 4x100W at 4 Ohm Class D Digital Audio Amplifier Board STA508 (TK2050) is rated 4.0 out of 5 by 8.
Rated 3 out of 5 by from The box says Clas-D ... STA508I bought this a while back, put it aside, never used. Now I saw other user commented it is not Tri-path class-T ... and LOL he was correct.Not sure what to make of this. This is probably one of the rare mistake PE made. But the product description does not seem to accurate.

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.

Does it have any way of controlling the volume? If, how/where? If not, is it possible to add? 

Asked by: Nikolaj
The board does not have any volume adjustment built in, it will have to be done via the music source or a preamplifier.

I have bought one of this amp a while back, haven't used it. And after getting ready to use it, found that it said in the box class-D Audio Amp - STA508 ?! I thought I was buying class-T ... so what exactly is the correct product description.

Asked by: gfyl
The correct description has it listed as a class T amplifier.
