input 2
both ch 1 & ch 2
logic inputs set for
normal operation.
Both inputs (ch 1 & ch 2)
are set for normal operation.
Normal operation allows
both inputs to be mixed and
sent to all eight outputs.
Hard-wired jumpers are then
connected to the appropriate
logic inputs, which mute each
input from specific outputs.
Input 1 (ch 1) is muted at
outputs 5~8. Input 2 (ch 2)
is muted at outputs 1~4.
