8 DLC170 Function Modules Installation and Operations Manual
DLC170 Function Modules
• Switch SW2—Enables audio embedding and controls various audio characteristics (such as the
destination group), the SFP alarm enable, 20- or 24-bit audio resolution, and the EMS enable.
• Switch SW4—Controls the termination of the analog audio input signals.
• Switch SW5—Controls the termination of the analog video input signal.
• Switch SW6—Controls the peak analog audio level that the DLC170AD can manage without clipping.
Artel ships the DLC170AD configured as follows:
• Analog audio source with 600 Ohm termination
• Analog video source with 75 Ohm termination
• Automatic gain control enabled
• Analog video pedestal enabled
• 24-bit audio resolution, +20 dBm (600 Ohms) peak audio level without clipping
• Audio embed enabled into destination group #1
• Analog video enabled through the BNC connector
• SDI grey field, at the NTSC rate, enabled if no video is present
• Audio mode set to 24 bits
• Alarm enabled for no SFP present
• Alarm disabled for no video present
• EMS override enabled (DL Manager can change the DLC170AD configuration)

Configuring Video Functions with DIP Switch SW1
Switch SW1 controls the various video functions of the DLC170AD, such as the video AGC, pedestal, and the
standby signal type. This switch also enables or disables the loss of video alarm function.
Figure 3 shows the DLC170AD configuration switch SW1 located on top of the PCB.
