I didn't get the email, but thanks Cristi. What VA rating for the transformers we need? Also, do we just need one of the power supply in your link for stereo? Thanks again.

the transformer should be able to deliver at least 750W, and should have one centre tap winding with 2x55-2x60V AC at at least 7A and another centre tapped winding wich has with about 4-8V more than the previous one and 50-100mA current.
i recommend to use one supply board for each amplifier module.

ta2022 briged mode
Hi CNX
I want to use the ta2022 in briged mode, Is there a simple way to do this
using an XLR(balanced) output from an active 2 ways filter ?

the easiest way to use the TA2022 amplifier in BTL mode with balanced input is to connect the inverted input to one channel and the noninverted input to the other channel. the loudspeaker must be connected between the outputs.

power supply
Hi cnx
I want to use a mean well power supply (27V DC) with the TA2022. When I connect the +VCC and -VCC of the power supply on the board (at the place +Vcc and - VCC soldering 2 wires on the board), the board dont works, the mute led is on and the power led go on and then slowly down. What is wrong ?
The board works right if I supply with a transformer on AC plugs. ?

J,
First, make sure that the SMPS has differential volage output, +-27V which means there will be +27V with respect to GND and a -27V with respect to GND. between the + and - should be 54V. single supply will not work properly since the voltage is not enough and by connecting just between + and - without GND is also not good. the current consumption on the positive rail and negative rail is not equal and it will create a voltage unballance which can destroy the ic if one rail have a voltage higher with 10V than other one.

Ta3020v4
New version of the TA3020 amplifier will be released soon. here are some pics of the prototype. This new version has the speaker protection, and SMPS on board. it is a compact design, just 100x200mm and includes about all what is needed for a complete medium power (250-400W/channel) class T amplifier.

Impressive!
Wow ! this module in now really meaningful!
All-in-one, small size (yes, size does matter 😀)
When do you expect it to be available for shipment?

If everything goes according to plan (in most cases doesn't; according to Murphy's laws) in about 2 weeks from now. i prepare the boards and parts for assembly then after assembly and tests they will be available for sale. Then i will know the price also, since i haven't got the assembly cost quotation yet.
The modules are stereo, and has input connector plus wires same as the previous versions. for speaker out and mains supply are screw terminal block connectors.
First batch of the TA3020 amplifier with on-board power supply is available already : Connexelectronic
