Thank you for your response. I will give it a try.

Eric,
Are any of your amplifiers used in commercial offerings? Sort of like how NAD uses Hypex...

Hi, Steve

One of my customers uses this FFA001 variant in their powered speakers, and they sell tens of thousands of this board. Sorry to inform you that I cannot mention their brand this time 🙂 .

Thanks,
Eric

Loving the slot race track; Scalextric?

Correct with some Fly cars. We've had it for 30 years

 

[Erica.C]

30 years fly cars, very good quality~.
To some extent, high-quality products are the best form of frugality, this is the pursuit of our products🙂 and our services.

Hello friends~

I'm back from the long holidays, and your orders are proceeding now, thanks all for your continuous support, I'll PM you for the tracking No.

PS: New cables with longer and higher gauges for reference, "Your voice mattered"~~ 🙂 😍

Thanks,
Eric

Hi Eric, good improvement to the cables! 👍

Another question: Can the 12V aux power be used to power a MINIDSP 2x4HD that calls for 12V 2.5W?

Ah never mind, I see you've stated it can only supply 12V/1A for a fan.

Hi, @Erica.C , Is here any possibility of you offering a lower gain input module?

I know I can change some resistors to lower the gain, but ”convenience is king.” 😊

Forgive me if I'm missing something, but 12V at 1A is ~ 12W, easily in excess of the 2.5W you need?

 

[Erica.C]

Yes, using this 12V to power minidsp 2x4hd is ok,

It's only down to unity gain with the current design. If need the minus gain, the i/o pcb needs to re-spin.

Thanks,

I'm planning to try a 2:1 step down transformer, mainly because I've got some suitable ones and I dont need lots of gain. 2:1 will reduce the gain to about 20db and
increase the reflected load impedance.

That’s good news, thanks. I’d be interested in 3 input modules, then. I’ll send a PM.

😳🤔 Not sure what I was thinking!

What is the height of the FFA001V3?
I found width and length on the first page.

 

[gpapag]

A mere 40mm.

I’m wondering how these will do stacked with 1/2” air gap

I’m wondering how these will do stacked with 1/2” air gap

I am doing face to face with (PCBs out) with 10mm gap in a square tunnel type box with a fan at each end cap. I don't foresee any issues with such setup. But stacked face to back and if used with fans would split the air path into less efficient streams and can be louder. Not sure how without fans would go

 

[mkane77g]

I may try face -back with 2” gap. 4 modules. The 2x150 runs much cooler than the 1x for some reason.

And whats hot? 40C,

 

[Randy Bassinga]

Running the H/B version. 40 sounds ok for the amp but if you mean air temp, doesn't sound very amp friendly. My ambient temps reached 36 Celsius today and my JLAudio car amp won't turn on until the air con cooled things down inside the car after starting. So with 10mm gap, I am running dual 80mm fans to create through flow to remove any buildup inside the case
