When you set this switch to ON position (green light on), the unit will be turned
on. When you set this switch to OFF position (green light off), the unit will

1 POWER Switch

The input jack of your

LTO Q is directly connected to the output jack when this

It is used to cause a "hard-bypass" and disable the equalization process in the
signal path.
