TDA7492 Digital Audio Amplifier Board 2x50W
TDA7492 Digital Audio Amplifier Board 2x50W is rated 4.1 out of 5 by 10.
Rated 5 out of 5 by from Excellent sounding ampI bought both this amp and the TPA3116 to try out. I used both for a portable decoder/amp receiver box I made and A/B'd these 2 amps with the same source and speakers. First 2 things I noticed were1. The TPA3116 has considerably less gain than the TDA7492.2. The TPA3116 has a very imbalanced frequency response that is overly forward in the midrange and upper midrange while the TDA7492 is much more balanced sounding, with a touch of laid-back midrange presentation.Comparing the 2 back and forth, I can to really appreciate how well balanced the TDA7492 is. It's overall sound is very pleasant and easy to listen to for Extended sessions. The TPA3116 just sounded off due to the imbalanced frequency response. The TPA3116 also seemed to roll off the very top octave while the TDA7492 didn't.Overall the TDA7492 exceeded my expectations for such a small and low cost amp. This will be my goto amp going forward for projects.

Rated 3 out of 5 by from OK Amp. TPA3116 is betterif you need 25- 30 watts a side and this is not a bad amp. it will go to 50 but it is ugly. For a few more buck use the Yuan-Jing TPA3116 Class D. The TPA3116 put out a true solid 50 watts. I use this and the TPA3116 to drive the ADX Shaker which feels Great.

Rated 5 out of 5 by from Good sound for the pricePacks a punch for the size and price. Powering it with an 18 volt laptop power supply

Rated 4 out of 5 by from Very good soundI would give it five stars if it had a 3.5mm input. The sound quality is very good and the extra power rocks! I've tried a number of ac adapters and it loves the 15 volt I have from an old iHome clock radio the best.

Rated 3 out of 5 by from Cannot hook up as a mono 100w. amp.Catalog description says it can be used as a 100w. mono amp. This is not possible.. Only as a 2x50w. amp.

TDA7492 Digital Audio Amplifier Board 2x50W

I added a revision to my question but it didn't post! I forgot to mention that I will be using at 4 ohms and the product description clearly states an 18v maximum. Can you please recommend a power supply?

Asked by: djdaveastro09
I would recommend using one like part number 120-055.

Where is the power input? Can I wire the Stereo harness to an aux cable?

Asked by: bruce123
A wiring diagram for this amplifier is below. Yes you can wire the harness to a 3.5mm aux connector.www.parts-express.com/pedocs/tech-diagrams/320-606--tda7492-wiring-diagram.pdf

Can this board be powered by a (19v5a?) universal power supply intended for a laptop? Part 120-502 for example. If not, what parts express power supply is advised for acceptable preformance?

I got this along with a pair of "HiVi B3N" (8ohm) and a "50K Audio Taper Stereo Pot" but I couldn't get it to work. I used the pot in the output side and eventually made it go stinky. Do I use pot on input side? Which and how to wire?

Asked by: mdeanda
a pot for volume control would be placed on the input side. Controlling volume on the speaker level side would require an l pad. You will want to use a 50k stereo pot with each input channel wired to one of the joined pots.

At the top of the page, to the right of "Product Details" there is the "Manuals & Resources". The first link is the wiring pdf you need.
