Hi,
i might wonder, is there a rule of thump how much you should have as cab buffer for a certain amp or at least what a certain minimum one should not undergo?
I am planing an 2.1 amp with two sure boards, based on an IRS2092, one board we'll be in stereo the other in btl. The idea was to either get two 500va transformers for each board one, or get one 1000va for both, to get enough headroom.
The stereo will have like 2x125 watt at 8 ohms the BTL 500 watts.
So now i was wondering how much capacitance, should i use on the rectifying board to avoid any issues.
Somewhere i heard years ago that there's might be some unspoken rule like for every 100 watt one should have like 10000µf of capacitance...but clearly thats not that case on most amps one could see.
So because of this, i ll try to get like an idea would could or should be usefull.
Woud be nice to get some informative replies. 🙂

Hi,
i had my post kindly moved by the nice mods, because i posted it former in the class D section...but no one seems to have an answer.
So hear (again) i am, asking if one might got an decent information on how much c, i at minimum should use for the givin setup.
The rectifying board will be this:
Module d'Alimentation lineaire 4 emplacements Snap in 35mm - Audiophonics
So enough space for decent caps. Question remains whats best suitable to drive the boards?!

I am sure I wrote something a week or two ago.
One totem-pole at 8 Ohms, 1,000uFd will be enough for cheap audio. If it is bipolar supply this will be two 2000uFd.
"Good" audio can be 2X to 20X this much. Often two 47,000uFd "just to be sure".
BTL needs four times as much.
Stereo needs twice, obviously.
4 Ohms needs twice, obviously.
