SMR 821 User Manual

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.
