3.4 Connection of Microphone
The Scaler Switcher provides with one 3-level microphone input port, to accommodate
different microphone input modes, including 48V phantom power mode, MIC mode &
LINE mode.
48V phantom power Mode
48V phantom power input has a good frequency characteristic, high input impedance
and high sensitivity.
When switching to “48V”, the MIC input will provide a 48V phantom power. This is only
used for condenser microphone.
Connect the microphone in this way: “+” connects to positive, “-” connects to negative
and “ ” to ground.
MIC Mode
MIC input has a low frequency characteristics, and wide frequency response.
When switch to “MIC”, the microphone input is used for connecting with dynamic
microphone. There are two different connection methods:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-”and “ ” connect to ground, and “+” connects to signal.

2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”
connects to ground.
LINE Mode
LINE input has a low frequency characteristics, and wide frequency response.
When switch to “LINE”, the microphone input is used for connecting with line audio or
wireless microphone output. There are two different connection methods:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-”and “ ” connect to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”

4. System Operations
4.1 Front Panel Buttons
Front panel buttons can be used for switching operations and volume adjusting.
4.1.1 Manual-Switching
Press 1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA on front panel to select the
corresponding input source.
4.1.2 Auto-Switching
Press AUTO to enter in auto-switching mode.
The auto-switching mode abides by the following principles:
New input
Once detecting a new input signal, the switcher would switch to this new signal
automatically.
Rebooting device
The Scaler Switcher have the ability to save the last configuration before losing
power. If the last switching mode is auto-switching, once rebooted, the switcher will
automatically enter auto-switching mode, then detect all inputs and memorize their
connection status for future rebooting using. If the last displayed signal is still
available, the unit will output the signal. If not, the unit will detect all the input signals
wit priority from 1-HDMI/MHLto 5-VGA. When detected the first signal, it will transfer
to output.
Signal removing
Once removing the current display signal, the Scaler Switcher will detect all input
signals with priority from 1-HDMI/MHL to 5-VGA. It will transfer the signal firstly
detected to be available to output devices.
Note:
When the DP signal is switched as input, the DP source device may not read the
EDID data from display device, at this point re-plug the DPsource device to solve
this phenomenon.
Auto-switching function works only when inputting new signal, removing a signal or
power rebooting. With any VGAport set to C-video or YPbPr, the system will be not
able to enter in Auto-switching mode.
4.1.3 Volume Adjusting
Press Volume Knob to choose MIC/Source audio needed to be adjusted, the
corresponding LED will turn green and keep on.
Adjusting the Volume Knob in clockwise direction to increase sound volume.
Adjusting the Volume Knob in anti-clockwise direction to decrease sound volume.
