4. Panel Button Control
4.1 I/O connection switching
The front panel features four input selection buttons and four output selection buttons
for switching I/O connection.
1) To convert one input to an output:
Example: Input 1 to Output 3
→ Press INPUTS 1 + OUTPUTS 3
2) To convert an input to several outputs:
Example: Convert Input 2 to Output 3 and 4
→ Press INPUTS 2 + OUTPUTS 3 + OUTPUTS 4
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
