That’s what I call amazing service!!
BTW, what’s nice is that the cable comes with the amp. being free is an added bonus but not necessary.

Thanks for your compliment, I just try my best to offer the necessaries to let our customers setup the platform smoothly~
Thanks,Eric
Hi, Bob,
With fan cooling, it can be worked at a high temp to 40C with your application.
Thanks, Eric
I done this test before, hope can answer your questions 😀
-- 120VAC input; 8ohm load x2; input signal = 1KHz sinewave; Room temp = 30C/open area; adjust the input signal to have 160W input power from the AC power meter; then after about 10-12mins, the thermal compressor limits the input power = 90W, and it can continuous running in this condition.
so, is there needs for a fan?
I will use them for bass driving in home set up and would like to run them without fan.
I do not understand that input signal of 160W or 90W, probably you meant output power or PS power?

It's input power. Based on the above data and your listening behavior, you can select a fan, re-enforced heatsink ( for amp ), or nothing for this module.
Btw, there is a temp.-controlled fan circuit at I/O buffer board, you can rely on it.
Thanks,Eric
I’ve buttoned up my 6-channel amp and have been running it nonstop with just two channels for a couple days. My chassis is fully vented top and bottom. There is perceivable warm air exiting the top, but it is nothing to be concerned about. I tried a few ways of incorporating fans in the chassis, but they either were too loud (the input module has ~20VDC out from the ‘fan’ points), or when slowed down with a DC-DC buck converter produced electrical noise in the output. Keeping it simple for home use (no fans) works best for me.
For the record, I tried inexpensive 24v fans, a 140mm 12V Noctua, and a 140mm 24v Noctua.
The amp sounds great and has plenty of power. The intended use for 3-way DSP crossovers will happen in the near future.

Good point. I forgot about that explanation, but in my testing, I did measure ~6V (I think) from the TEMP VAC spot on the I/O board. I tried powering one fan with that, and the speed was good, but there was still noise on that amp’s output with the fan connected. I Imagine there’s some combination of logic that would get me noiseless fan operation, but I gave up and removed it.
Hi,Bill
Thanks for your follow-up.
The FFA002 may announce later than FFA003. And FFA003 can ready to order in 2 weeks (limited quantity😀)
And the preliminary price of FFA003 will be $59.9 W/O shipping, and I/O board is $5.99 with accessories. We will have a volume control on this I/O board. Please let me know if you have any comments.
Thanks,
Eric
