Do not connect the grounding output cable with the grounding input cable as
this action causes a short circuit to occur.
Audio Input Cable
user can select the input method according to the equipment storage environment.
Use RJ45 Port:
The See Table 3 for the pin descriptions.
Note:
Do not use the RJ45 port and
terminal blocks
at same time.
Instead, plug the CAT5 cable into the RJ45 port.
Use Terminal blocks:
Notice:
If the audio input cable is supplied by the installation personnel, the cable
must be shielded.
DA has a balanced input connection. A balanced connection is recommended to
reduce AC power interference, especially when using a long cable. For short cables
that have an unbalanced connection, the signal impedance should be less than 600
ohms.
The following steps describe connecting a balanced input connection:
1.
Pull the input cable through the
terminal
protection
cover, as shown in Figure 1.
