Rear Panel Connections
The standard 3U Screw terminal rear panel is shown below. Other 3U and 1U panel variants
with screw terminal and/or BNC connectors are similarly marked. Table 2.1 describes the
connections to the unit when these panels are used.
Notes on Table 2.1:
1. Table entries in italic text denote the connections to be made when the input or
2. Table entries in regular text denote connections to be made when input or output
3. When input or output audio is digital, certain connections are reserved. Do not
4. Grounds/screens (S) are connected to chassis on all outputs and inputs and
5. On units with analog output option, neither (+ or -) output should be grounded.
