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.
