Class T Audio Amplifiers

Thanks, seems to be ok now;

Also can you bridge the V3k? suitable for 8r ;

[Cristi]

Yes, the TA3020v3k can be bridged IF the BIPS module or some similar circuit is used, to provide 180* out of phase signal for one channel.

just received my v3k.. is there any documentation to go with it? I assumed I'd be able to figure it out from the silk screen, but not a chance.

[Cristi]

yes, please try the link from the webpage. www.connexelectronic.com/documents/TA3020v3k.pdf

Assaf,

i sent you the schematics by mail. let me know if you need any help to repair the board.

Hello Cristi,

If I have well understood: we can put directly a balanced signal to a V4 board in btl mode (without the bips board)? Sorry for this silly question but, English is not my language.

Hi Dany,

if the input signal is truly balanced, which means that the same component and amplitude can be found on both wires, but one is 180* out of phase, then yes, can be used to drive the TA3020v4 directly in BTL mode. this is valid for any stereo amplifier, even class AB.

Cristi,

Do you have any picutres of the TA3020 V3D including the remote led/volume board?

Your website shows good pictures of the main amplifier board, but nothing of the remote board. The V3D is a really nice product with the bips. A shame that you could not make the V3D with the bips+smps in one, it would probably have a really high price then.

The current controller board has just potentiometer and swtiches for Mute, BTL. Balanced/Unbalanced and Power, BTL, Mute, Balanced/Unbalanced LED's.
I intended to develop another controller board, DSP based. Time is not on my side in the past few months, so i cannot say when will be available, of course if will be interest i can put it on the priority list.

I'm trying since yesterday morning to upload these two pictures.

Thanks Cristi! The 3D and the 800 together is a lethal combination. I have been lurking here, wanting a LJM + Cristi SMPS. But I feel your T-Class might be better sound quality, even if it cost more in the long run.

Thanks for the pictures
