Connections
Connecting the SMR 821 is not much different than any other analog audio
product. There are inputs and outputs, but there are also additional connec-
tions that you need to be aware of . These include the external control ports
and the Bus Link connectors. All cables for these connections should be
shielded.
Refer to the following illustrations for each type of connection.
Audio Input
The inputs to the SMR 821 are balanced. This means that there are three wires for each connection, a positive, negative and
shield. These should be connected to each pin accordingly.
