4. Panel Control
4.1 Input Source Switching
The button “SOURCE/MODE/3s” on the front panel can be used to select input
source and switch mode.
4.1.1 Manual Switching Mode
Press “SOURCE/MODE/3s” button to switch circularly among input 1~4, the
corresponding indicator illuminate green synchronously for easy recognition.
4.1.2 Auto Switching Mode
Press and hold the button “SOURCE/MODE/3s”for 3 seconds or more to switch
between the manual and auto modes. (Default: Manual switch.). Once enter
auto-switching mode, the “AUTO” LED will light up.
The auto-switching mode abides by the following principles:
New Input
Once detecting a new input signal, this switcher would switch to this new signal
automatically.
Power Rebooting
This switcher support power off memory function. If the last selected signal is still
available, the switcher will still output the signal. If not, the switcher will detect
all the input signals with priority from “IN 1” to “IN 4” ports. When detected the
first signal, it will transfer to output.
Signal Removing
Once removing the current input signal, this switcher will detect all input signals
with priority from the next input port. It will transfer the first available source to
the output device.
For example, the selected input signal is “IN 2”, if you disconnect the current input
source, MUH4A-H2 will detect all input signals according to the following order:
“IN 3”, “IN 4”, “IN 1”, and then the first available source will be switched as input.
