Memphis Mode Override
There are two switches on the VMC printed circuit board (PCB) that control Memphis Mode. An
internal switch allows you to override Memphis Mode, regardless of the external switch setting.
SW1: ON (Allow Memphis Mode)
Board switch SW1 labeled “
Stop
” (red outline on graphic) is located on the PCB inside the VMC
enclosure. SW1
ON
(default configuration) allows the external switch and ¼” jack to operate
Memphis Mode. However, if you want to completely disable Memphis Mode, set SW1
OFF
. This
will override Memphis Mode and the
Normal / Memphis
external switch will only operate in
Normal mode, regardless of switch position. Any switch connected to the
Stop Switch /
Memphis Mode
¼” jack will only operate full Stop.
SW2: OFF (Memphis Mode – User Selectable)
Board switch SW2 (yellow outline on graphic), externally labeled as
Normal / Memphis
, selects
whether Memphis Mode is enabled or disabled. SW2
OFF
(
Normal
) allows the Leslie to operate
normally with both upper (horn) and lower (bass) rotors spinning. SW2
ON
(
Memphis Mode
)
disables the bass rotor and only allows the horn rotor to spin. Fast, Slow and Stop are fully
supported on the horn rotor in Memphis mode.
