Operating Your XGA / Audio Switcher

INPUT SELECTOR buttons 1 on the second and third units are inactive. You
cannot connect INPUT 1 on the second and third units to an independent
source because INPUT 1 on the second unit is connected to the OUTPUT on
the first unit and INPUT 1 on the third unit is connected to the OUTPUT on
the second unit.
INPUT SELECTOR buttons marked 1 to 8 on the first looped
VP-81xl unit
operate INPUTS 1 to 8, respectively. INPUT SELECTOR buttons marked 2
to 8 on the second looped VP-81xl unit operate INPUTS 9 to 15, respectively.
INPUT SELECTOR buttons marked 2 to 8 on the third looped VP-81xl unit
operate INPUTS 16 to 22, respectively.
