If you find the audio levels too low in PC try boosting the audio using the sound card built in feature like smart volume (creative sound card) I think it is loudness for realtek chipset it is also sometimes labeled ALC (Automatic volume level).
Browser extension like audio compressor is also an option if the above is not available.
See u next time.
Very very good clip!!! Thank you!
Glad you like it and thank you for dropping by the channel.
good
very informative, thank you
Thank you too.
HI ! Ver Accurate JOB !!! Congratulations !
What is the exact type of your DC filter ? Are You use 3 Amper DC Supply on 48 Volt or more Ampers ??
It is a 48 volts 8A power supply, the output is set to 50 Volts.This is the Power Supply used in this test - th-cam.com/video/zySfe_MrDFA/w-d-xo.html
A 3A filter will work but I'm using a 10A here so the voltage loss thus the power loss on the filter is minimal.
You can get the filter on alixpress, you can search for the filter on google using this " DC LC Low pass filter 10A 20A EMI electromagnetic interference DC switching car audio Amplifier ".
Thank you for dropping by.
This filter (as I see) that You have used works on 12-24Volt. It is no problem when Your switching transformer works on 48Volt ??
Or please attache a link that shows directly Your filter if possible! Many thanks!!!!!
This is the exact filter in the video, it is the 10A version www.aliexpress.com/item/1005004509784253.html? .
Works no problem for 12-24V.
Aconsejas su compra para un uso en la casa como auido del hogar..aguanta secciones de escucha prolongadas?
It is fine for home use.
Use a decent quality power supply.
For extended use at medium to high volume level, I suggest adding a low noise fan to help dissipate the heat.When using an enclosure choose one with adequate ventilation to push the heat out the case.
282 watts 4 ohm per channel or bridge?
282 watts per channel at 4 ohms
I looking many time the BDM9 . Have maybe more power
I doubt the BDM9 will do better than the BDM8, they are using same chip after all.
Shall I test the Wondom TPA3255 with 53.5V power supply?
@@boknoynaruto3824 on this board have one chip and on many tpa3255 boads can only 42 volt . I think the wondom can only 48 volt .
Sorry, but I don`t understand any of your mumbling... please spek more clearly or get a better mic next time
