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.

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:

Application

The PT-PSW-52H has a good application in various occasions, such as computer realm, monitoring, conference room, big screen displaying, television education, command & control center and smart home etc.

Button Control

Manual Switching

Press 1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA on front panel to select the corresponding input source.

Auto Switching

• 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 with priority from 1-HDMI/MHL to 5-VGA. When detected the first signal, it will transfer to output.

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.

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.
