*Default Factory Settings.
The S/C column denotes standard jumper settings for either stand-alone (S) or control port (C) operation.
8. DESIGN NOTE
CDB4351 Revision A.0
The FET muting circuit must be bypassed by placing a shunt on J13 and J21, otherwise unwant-
ed noise will occur while muted.
CDB4351 Revision B.0
There are no known issues on this revision.
