Zerone Audio Amplifier Board Digital, TDA7498E 160W + 160W High Power Channel Stereo Amplifier Module Supports BTL Mode, 4.25 x 3.1in

Decent amplifier. No instructions, which wouldn't be so bad, but there are also no warnings. Sound quality is good, bridging to PBTL isn't difficult (though it does require soldering, would be good if it were switched). Using for a couple of low powered bass amplifiers for practice and experimentation. The bad- know that in either mono or stereo mode the output(s) are bridged and the NEGATIVE OUTPUT MUST NOT BE GROUNDED or you will instantly destroy the amp chip on the board. THERE IS NO OUTPUT PROTECTION. This includes connecting to an oscilloscope. Don't ask how I know:)

I built a stereo power amplifier with this board operating at 31.5 volts DC, and it provides plenty of output into an 8 ohm load. The heat sink gets up to approximately 100 degrees F. which appears not to be high enough to activate the fan. It would be better if the fan came on because lower temperature operation means longer chip life. I had to do a lot of web research to determine how to use the jumpers, set the gain control and determine configuration alternatives.

The board came with a bridged trace (see picture with bridge circled in yellow) that I had to cut as I wasn't getting audio from one channel. After spending hours troubleshooting, everything ran fine via an 18v 5amp power supply and I built a nice case for it. I even redid the thermal grease with arctic silver. It worked well for 4 months just playing internet talk radio before letting out the magic smoke. The output inductors just flap around in the breeze, not even hot snot to help secure them.

No bluetooth listing says it comes with bluetooth

Se equivocaron y lo mandaron para el norte cerca de Chicago, pero lo mandaron nuevamente con prioridad..Todo bien..

Power light comes up but no signal to speakers

It has a guitar amp Home that goes away, or is hidden as you turn the volume up, decided to make it mono four my subwoofers hand case from a Fussi amp that died got sick of the wires so I had made this RCA in the back and use some epoxy to hold it in place but it has solid terminals. Plus, I added an indicator light too much junk on the back just barely could slide it in the case, not worried about on and off switch Have it hooked up to a remote shut everything down tried some noise suppressors they didn’t do anything. What do you expect for 20 bucks?

For its size, this is an amazingly powerful stereo amplifier. After watching several YouTube reviews, I am not disappointed with the performance of this amplifier. I am powering it with a 24V DC- 0.6 AMP power adapter. Into a pair of Realistic 8 ohm Minimus 7 bookshelf speakers. Using a Classic iPod for input source. This is loud enough that at half volume it is still packs a punch in a bedroom sized room. I'm sure if you supply it with the max power (36v dc) it will be more than you will need for a very large room. Very clean sound, no static hiss, or scratch from the volume pot. It was shipped from China by Airmail and arrived very quickly about 7 working days. Packaging is a very flimsy to say the least, if not properly handled it could easily be damaged. Seller should consider bubble wrap envelope or cardboard box at the very least. A very important thing to consider, when connecting the power and speakers wires, I found the screws were very tight and when I was trying to loosen them, the whole terminal block started to twist. Best to get a very good grip on it before attempting to loosen screws looks like it would break off the board very easily. Great value for the money.
