Hi, Bill
Thanks for your feedback, unluckily, we got all the PCB ready now. May think to add a volume pot next time for a better use scenario.

Thanks,Eric

Eric,

Do you have plans to integrate a DSP to your amps? Right now there are no good/non expensive DSP plate amps for DIY active speakers. Either you go expensive with HypeX Fusion amps or you go low performance with ADAU1701 ADC.

An ADAU1701 with upgraded ADC & DAC + a good class D amp should be a killer option for active speakers!

Hey, Bro
Thanks for your suggestion.
Actually, Our product roadmap has an FFA002-V1 variant with MOSFET mounted at the bottom side of the PCB, then transfer the heat to the AL plate, the power rating will be similar to Pascal Tpro, and we'll create the DSP I/O for this board. And It will also be backward compatible with this FFA001-V3 module.

Thanks,Eric

Great! Looking forward to that amp+DSP then! Any ETA? Or more info on the DSP, ADC and DAC choice?

Hard to get better performance than -90dB THD+N with the ADAU1701, no chance of using something like one of the ADAU146x together with some half-decent DAC's?
Would be very nice to see >100dB THD+N throughout the signal chain, that is the biggest reason I would go for an external DSP solution.

Looking forward to the FFA002 and FFA003 designs.

Agree with you that using the inner codec from ADAU1701 cannot get better THD+N performance, that's why I select the external codec to bypass its inner one.
And, thanks for looking into this thread, with your guys' suggestions/support, give me much confidence in our design.

Thanks,Eric

Excellent!!

CS4272 have good performance ADC and DAC, maybe not SOTA, but very good indeed. Manage a good 2 or 3 channel amp + DSP and I assure you you will sell many of them in this forum.

DAC THD+N (dB)-100
ADC THD+N (dB)-100

Just to keep track of the amps:

FFA001_V3
Size: 90x150mm
Input: 85--265Vac, constant power SMPS
Output: 2x150W @ 4 / 8ohm
also be configured as a high-bass mode--- CH1=300W@4OHM and CH2=120W@8OHM, similar to the Pascal U-PRO2
Price: USD$49.9/Unit, w/o shipping

FFA002_V2 2x350W
FFA002-V1 variant with MOSFET mounted at the bottom side of the PCB

FFA003 1x350W

Thanks for your summary. 🙂 , and some updates here:
FFA001_V3 -- The high/bass version, need to change the output MOSFET and adjust the current limiting, if needed, please info. cannot implement on the customer's side.
FFA002_V2 --- universal power supply, size = 95*200mm
FFA003 -- universal power supply, heavy-duty design, convection cooling, size = 90*245mm.

Thanks,Eric

It’s not pretty or exact millwork, but I’m getting there. I need M2(?) screws and nuts for the Neutrik input jacks, and connector headers for the mains inputs and speaker outputs…
