3.3.2 Balanced Input Wiring

Balanced sources should be wired as shown below. Notice that the 
shield is not connected to the chassis ground of the source if the 
source is also connected to the AC ground (that is, it has a grounded 
AC plug). This prevents unwanted ground loops.

3.3.3 Unbalanced Input Wiring

Unbalanced sources should be wired as shown below. The examples are grouped 
according to whether you use twin-lead shielded wire or single-lead coax (or 
twisted pair).

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.
