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.
