Sure Electronics 2x15W at 4 Ohm TA2024 Class-D Audio Amplifier Board Only is rated 4.6364 out of 5 by 11.
Rated 5 out of 5 by from great amp; no hissing like Lepai 202Bought this for a homebuilt BT Boombox 18 inches wide, 6.75 inches high and 7 inches deep (all external dimension). the 2x15W amp drives 4 ohms Klipsch ProMedia satellite speakers installed in a 450 cubic inch box along with a 60W mono amp driving a TangBand 5.25 subwoofer. Both amps are connected to the Sure BT board (which is awesome by the way). The boom box has extension down to 50 Hz as modelled on WinISD. The whole thing being driven by four A123 LiFePO4 cells controlled by a BMS board to provide as much as 30 amps if the amps could even draw that much instantaneously.

Rated 5 out of 5 by from Very good quality!The quality of the board is outstanding! I had used almost 70 of the DTA 2 amps and got a bad batch of about 15 of them which made me jump ship and buy this board. I wish I would have switched sooner! This board is louder and "tighter" sounding with better bass and better clarity.

Rated 4 out of 5 by from Good amp with decent power for near-field useBought this little amp a few months ago, and finally got a chance to use it in a nightstand speaker to watch movies on my tablet. Amp stays cool even after running it awhile, but I'm using 8 ohms speakers so that helps. Does pop a little on turn on, but I leave it on all the time anyway so it's not a concern. I may use the mute feature in the future if it becomes an issue. Deducting one star because of the turn-on pop since it would be quite easy to build anti-pop right on the board with minimal parts or additional manufacturing cost. I did have a little noise from the input when the tablet goes to sleep, but wrapping the signal input wire a few times around a small ferrite donut solved that. So the noise was not the amp's fault. I do like that there are multiple options for input and output connections. Since this amp is installed inside an enclosure, I opted to solder everything to avoid connectors coming loose over time. As a result, I removed the DC input and speaker output terminal blocks to use in a future project.As far as the rest of the project is concerned, I used all PE parts. The input area is simply a speaker terminal cup with the binding posts removed and hot glue was used to seal the holes. The amp mounted perfectly to this cup making it an easy-to-install module with very short wires needed. Since I'm running 8ohm drivers, I only needed a 12v 1.5A regulated power supply to get full power out. The box is 0.065ft^3 net volume with a 1" x 2.7" flared port. System is tuned for 96Hz with an F3 of around 85Hz. Really needs a sub for deep notes, but is adequate as-is especially being so close to my ears.

Rated 5 out of 5 by from Good inexpensive auto sound ampI used this in an old Jeep. IT works well with an iPhone as the source. It is small enough to hide out of the way and if by chance it got stolen it is not too expensive. Clean sound driving a small pair of speakers.

Rated 5 out of 5 by from Simple and smallI have bought four of these little amplifier boards to go in custom speaker boxes made out of vintage train cases. The small size works great with these very small boxes and the quality of sound is great.

Rated 4 out of 5 by from Great amplifier boardI bought this for an arcade cabinet. This is a great product: it's very easy to install, no soldering required, the cable connectors are awesome. It also sounds really good. I'd give it a full 5 stars if there was a volume control module that could be easily installed as an option :)

is there any way to add volume control to this amp? I want to use it in a retro pi arcade project.

Asked by: imalan54
You can add a stereo potentiometer between your source and the amplifier. I have personally used one (023-646) and it works very well.

I would like to power this with batteries as a portable amp. Can I just hook the batteries up directly or do I need some sort of intermediate circuit in between the batteries and the board?

Asked by: cspirou
As long as the battery is 12VDC you do not need anything between the battery and amp.

Would a 4.5 amp power supply hurt this amp?

Asked by: The Tank
No as long as the voltage is in the recommended range. The amp will only draw the current it needs.

Power Supply Connection Can the power to this board be connected with screws? If so, what size of screws do I need or does the board come with the screws neccessary to do it? Thanks

Asked by: DanL
The power supply connection uses a 2.1mm dc plug but can be wired directly to the pcb or with a 2 pin phoenix type pcb mount terminal block.
