4. Control Operations

4.1 Front Panel Button Control

Users can control the AVS1600 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”

NOTES:

1. Switch Mode: Audio and Video synchronized (AV) or separate switching mode

(Audio/Video).

2. Input Channel: This is the number of input channels to be controlled.

3. Output Channel: This is 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 counted from left to right, top to
bottom.

5. The input delay time between two numbers of every input and 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”, “A l l”.

Functional Buttons:

UNDO button: return to the previous status.

Example: Input 6 is connected to 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: Provides a 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

input 1—>output 1, input 2—>output 2, input 3—>output 3 … input 8—>output 8.
