NOTE 1: CSN/RSN are optional locations, loaded only if required to reduce overshoot
NOTE 2: CCASE (4 locations) represent bypass capacitors mounted at the exit of the speaker cable from the cabinet. They are optional and
are used for EMI supression. Lead lengths on these components must be kept short to be effective. They are shown in this schematic for
reference.
