hi guys!
i've just made this power output stage with 4x 2sc5200 and 4x 2sa1943 and now i had to choose a good input and vas stage to connect it. since i want to use these boards for an active subwoofer at 2 or 4 ohm i'll need high efficency with at least 1kHz bandwidth. which kind on input and vas do you suggest?
supply will be dual 37vdc.
have i to add recirculation diodes at the output? i'm not sure the term "recirculation" is correct 😉
any suggestions will be very appreciated!
i'm also projecting a microcrontroller based volume and frequency controllers with infrared remote when finished i'll post schematic and pcb
