4. Control Operations
4.1. Front Panel Button control
Users can control MMX88A rapidly and directly with its front panel buttons. Here is a
brief operation guide to front panel buttons.
Format: “Input Channel” + “Switch Mode” +“Output Channel”
Note:
1) “Switch Mode”: Audio & Video synchronal (AV) or separate switching mode (Audio/
Video)
2) “Input Channel”: Fill with the number of input channel to be controlled,
3) “Output Channel”: Fill with the number of output channels to be controlled. Press “All”
to select all the outputs.
4) The input/output channels on the rear panel are counting from left to right, top to
bottom.
5) The input delay time between two numbers of every input& output channel must be
less than 5 seconds; otherwise the operation will be cancelled.
Example:
1. To transfer input 1 to output 11, press input “1”, output “0” “1”.
2. To transfer signals from input 1 to all output channels, press buttons in this order:
“1”, “All”.
Functional Buttons:
UNDO button: return to the previous status
Example: Input 6 is connecting with output 6, press input “6” + “AV”+ output 4 to change
the connection. Press “Undo” to enable input 6 to reconnect with output 6.
 button: If you press buttons “1”, “AV”, “2”, “” in order, then “2” will be canceled.
THROUGH button: get straight I/O connection, e.g. input 1-> output 1, input 2-> output
2.
Press “Input Channel”+”Through”
Example: If you press buttons “ALL”, “THROUGH” in order, then the result will be like
input 1 output 1, input 2output 2, input 3output 3 … input 8output 8.
