3.3.4 Balanced Monitor Output Wiring

Balanced Monitor Output wiring is shown in Figures 3.5. Notice that if the load is connected to AC ground, the shield should not be connected to the output ground terminal. This will prevent unwanted ground loops.

1.Assemble a 2-conductor shielded cable with a Phoenix-type 3- terminal connector on one end. On the other end, solder a con- nector that mates with your booth monitor amplifier/speaker.

2.Plug the Phoenix-type connector into the Monitor Output con- nector on the back of the DBC Network Bridge.

3.Plug the other end of the cable into your booth monitor ampli- fier/speaker.
