are transmitted by the IR panel. Balanced, differential input. One
side of each may be grounded for unbalanced sources. Ground
at source is recommended.

It is easier to configure and test the IRC-28 before it is installed. The configura-
tion and test procedures are listed below.
1. Connect the power supply to the IRC-28. Note the + and - terminal marking
near the terminal strip. Connect the positive (red) wire to the positive terminal.
2. Connect the HI audio to the channel A terminals of the IRC-28. Connect the
VI-N audio to the channel B terminals. Two conductor shielded twisted pair cable
is suggested for each audio channel. Connect the two conductors to the + and
- terminals of the appropriate channel. Connect the shield to the adjacent ground
terminal. If an audio source is unbalanced, connect the - lead to the shield at the
audio source.
