: This subharmonic generator adds perceived low-end depth without physically taxing the speaker. On the circuit board, this is often implemented as a dedicated sub-circuit that generates subharmonic frequencies below the primary signal.
: A critical safety circuit that prevents power amp clipping. The schematic shows a compression loop that automatically reduces gain when the signal reaches dangerous levels, protecting the 15-inch heavy-duty woofer.
The MAX 115 schematic reveals several "Peavey-exclusive" technologies that define its sound:
