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