S-4000S Channel Numbers
To facilitate custom labeling for a particular installation or multiple S-4000 Systems, the S-4000S is
shipped from the factory without channel number labels on its input and output modules.
The illustratration below shows the S-4000S’s channel numbers as they correlate to the S-4000H’s
audio I/O and input channel selection on the S-4000R.
If desired, use the included adhesive-backed number label sheets to affix channel numbers to
the S-4000S’s input and output modules.
