Thanks for reaching out, would you mind PM me to leave your mail? I can send you the test data for reference~
Appreciate you like it. In fact, it's a very compact design -- we have Main + Aux PSU design for energy saving, we also have the clip limiter circuit integrated and it also has the temperature compressing function on the amplifier side
What do you mean by high bass mode? Looks to me that Ch 1 will power the woofer and Ch 2 the tweeter/compressiondriver.
If so it's an interesting concept.
Kind regards,
Willem.
Hi, Willem
You're correct. In the high bass mode, CH1 will have more output (300W）to power the woofer, while CH2 will limit its output for the tweeter.
Regarding to this configuration, we need hardware-change the current limit for each output, and this module will be the variant version, which is our original design platform to support our biggest loudspeaker brander.
Thanks
Eric
For a single drive, it's 300W@4ohm at CH1 for high/bass configuration.
For stereo version is 2x 150W @4ohm limited by the output current setting, while 2x150W @8Ohm limited by the output voltage setting.
Thanks,
Erica
Hello friends~
Since many of you are asking about the input buffer board, here, I am making the consistent announcement-- we'll provide the free charge of one set XLR input buffer + the 26pin ribbon cable for each customer.
And, regarding the AL basement, since I just demo to make them together, there is no mounting hole to fix it to your project, I do not think it's useful to you. If you like, I can offer one free sample to the first 10 customers.
Maybe in the future, I'll make the right mount hole for this aluminum plate, then you can put it into your products~~
Thanks,
Erica

Seems like a nice and interesting design.
I would only really like to see the mosfets on the other side of the board.
Which give much better thermals as well as better system integration.
(easy to mount on a plate for example)
Would it also be possible to show the THD+N charts in the more conventional way, it's rather confusing atm?

Hi, b_force
Yes, the output MOSFET + rectifier diode was screwed on the heatsink with the insulated ceramic plate, which was well dissipated by this tooled Heatsink, I'm glad you like it
To explain the THD+N data, I test the 100/1k/6.65K frequency with output power from 0 to rated output @4/8ohm, and each frequency with a different color to be marked in the test data.
Thanks,
Eric
