TDA7498 100 watt class D amplifier test

This one is available here

your videos are very helpfull yesterday i fixed my pioneer stero ampflier A-227 when turned the amp on to the cd player and played the cd i got crackling sound on the right channel of the speaker i thought by pushing speaker slector buttons that would solve the problem lone and behold it did not solve the problem so so yesterday i went to the home depot store and got circuit spary and i started spraying every switch and the slector nob on the amp after that i solved the problem when turned the the slector nob on the amp to cd i put in a cd and play the quality of the sound blew my mind the amp sounds like when the it come out of the factory

I wonder if this class D amp could be used as a substitute for a dead STK power module running at 39 Volt. If I remember well a class D amp needs the grounds of the output channels to be separated. One shared output ground, like in a standard amp chassis, may kill the class D amp. Anybody?

What are you doing with a Tektronix 24658 living on the same workbench with a $200 UNI-T??
It's like having a 2020 Rolls Royce Ghost and riding in a KIA Rio...

Could you put a dummy load on the output, then a sign wave on the input and look at it on the scope.

I also have to class d boards with this chip they can do about 50watts or even up to 70Watts on 24v an 4Ohms

After watching this video found a excuse now to use my new Keithey 2015 THD meter that just finish overhauling. Have a few of these amp's modules laying around. Now just need to find some over 100w resistors for dummy load on feebay.

Review it again with toneboard
I wanna know how big is the difference
When you put a toneboard

Hi. Great review.
I have an old Pioneer 8ohm 3way speaker . 8" woofer I think 80 w power handling.
I want to make a Bluetooth boombox powered by a 21. 6V 5Ah drill battery from HILTI.I think it can play music for 5-6 HR.
Can you suggest me a decent board for this purpose? Thanks

have the same one, can't get sound on speakers, light is on but no sound?? any experience with this? my model is sanwu TDA7498, same processor, no bluetoot, put it on 19-20V and 5A, checked on two different power supplies and different speakers, no sound.. it's new, unpacked but no sound.. i use power supply from laptop power cable.

Hi, Can we use 24volt power supply? I mean, does lower voltage affect its efficiency? Thanks for your attention. I’m looking forward to your reply.

Thanks for the video, very helpful as I have one on order. Can you let me know the name of the royalty free music played in the demo?

[mitacccosminmc]

i use one on sony 6ohm speakers fromn an rg660....powered by a laptop psu rated at 20v 6A sounds ok
but my lc filters it's warmer than the other components....
can this be a problem ?

[rohitb]

Which one is better tda7498 or tpa3116d2?

[KuntalGhosh]

Where is the power output numbers? 🤦 Dude u have an oscilloscope pls measure the clean maximum power output and harmonic distortion!!

[eriknau]

I'm wondering what the pin configuration is to the Audio Input Socket shown in the picture. How can one use them?

[infohackerinfo]

how much signal voltage it needs to obtain the rms power? and. you can meassure the power of the tda 3116d2 2.1ch 50+50+100w?? greetings

[oxay]

how convert output L- R- to Gnd for stereo 3.1 jack for headphone and protection my headphone from high sound in this amp ?

[profd]

I had a question that relates to Class D. I'm thinking about buying a Class D solid state guitar amplifier, but I heard that Class D amps lose a lot of their power (more than Class A or A/B amps do) when they drive speakers above 4 ohms, and my speaker happens to be 8 ohms. Is this so? If it is, the high watts the amp manufacturer claims for the amp don't seem as impressive.

Hello, I am writing from Turkey. I also bought this circuit. I would have a question. How many volts and amps can I connect?

[crashbandicooteverr]

How is the sound of these compared to a vintage STK-based 30 WPC receiver?
