Media Converters
In standard audio systems, there are two media converter/network switches, one in the
fiber box and one in the control enclosure, that transfer digital audio signal. Looking at
the connections and LED indicators on these devices help with system troubleshooting.
Note: These devices are not used in analog-only systems.
Typical Component Settings
• Ensure power is connected to green terminal block (Red to V1+, Black to V1-) and
the two BSP DIP switches are both set to ON. Refer to Figure 32 .
• Verify fiber cables are connected to RX and TX. Refer to Figure 33-3 .
• Verify Ethernet cable connection(s) from other equipment. Typical connections for
standard systems are as follows:
• Fiber Conversion Box: 1 connection to ADC1; see
Input/Output Expander (p�22)
• Control Enclosure: 1 or 2 connections for amplifiers (varies per audio system)
