3.4 Microphone Connection
The PT-PSW-52H 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.

4. System Operation
4.1 Button Control
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 PT-PSW-52H 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/MHL to 5-VGA. When detected the first
signal, it will transfer to output.

User Manual
PT-PSW-52H

Signal removing
Once removing the current display signal, the PT-PSW-52H 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 DP source device to solve this
phenomenon.
Auto-switching function works only when inputting new signal, removing a signal or
power rebooting. With any VGA port set to C-video or YPbPr, the system will be not
able to enter in Auto-switching mode.
4.1.3 Volume Adjustment
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.
