Check the description above for the quick test results for the TPA3255. Please subscribe to help the channel, comments down below, like or dislike, Please Share and thank you for watching. 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.

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 ??

@boknoynaruto3824 4 месяца назад

It is a 48 volts 8A power supply, the output is set to 50 Volts.This is the Power Supply used in this test - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zySfe_MrDFA.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!!!!!

@boknoynaruto3824 4 месяца назад

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.

@@boknoynaruto3824 Can you do a video showing the DC signal before and after applying the filter?

@boknoynaruto3824 2 месяца назад

You mean the Power Supply Ripple before and after the filter? Yeah I could do that.

Aconsejas su compra para un uso en la casa como auido del hogar..aguanta secciones de escucha prolongadas?

@boknoynaruto3824 5 месяцев назад

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?

@boknoynaruto3824 3 месяца назад

282 watts per channel at 4 ohms

@KGrasso89 2 месяца назад

How many amps is your power supply?

@boknoynaruto3824 2 месяца назад

The power supply can do 8.5A, over current protection kicks in at 8.6A.

@KGrasso89 2 месяца назад

@@boknoynaruto3824Thanks for the quick reply. I have a similar PSU from Drok that is adjustable from 0-48v but goes to 51v and is 10amps. How much rms power you think the bdm8 board is capable of driving both channels? I've been eyeing the bdm8 board as well as the one made for parts express and branded as a Dayton for awhile now. I've looked on here several times for a review of them and haven't come accross any until your video. I will be ordering one from AliExpress now thanks to your video!
