3.3. Connection Procedures
Step1. Connect source devices (e.g. PC, DVD) to video input ports with corresponding
cables. For example, connect VGA INPUTS ports and the VGA ports of source
devices via VGA cable.
Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT
port of Scaler Switcher with Digital Amplifier-TN with audio cable separately. C-
VIDEO1 shares the same audio input port with S-VIDEO3; Pr-Pb-Y shares the
same audio input port with C-VIDEO4, you can select either side as audio input
port.
Step3. Connect a microphone to the MIC input port; plug an audio source device or a
wireless microphone to the LINE port.
Step4. Connect a control device (e.g. a PC) to the TCP/IP ports or RS232 sockets of
Scaler Switcher with Digital Amplifier-TN. Send commands to control Scaler
Switcher with Digital Amplifier-TN via control software.
Step5. Connect the HDMI HDBT port of Scaler Switcher with Digital Amplifier-TN with
