Step 1. Wire the Red & Green (tip and ring) pair of wires
to screw terminals 6 & 7.
Step 2. Wire the Yellow & Black (24V power) pair of wires
to screw terminals 8 & 9.
Step 3. Adjust volume manually at each speaker.
2. Bogen or Valcom Four-Wire Speakers
The SA-25 is backwards compatible with legacy four-wire self-amplified loud speakers such as those from Bogen or Valcom.
Use wire gauge size chart on previous page, but go two sizes larger since 24V power has more current loss then Vikings 40V
two wire protocol. For example, the chart says to use #16 gauge wire for 8 speakers on a 1000 foot run; but instead use #14
gauge wire when using Valcom and Bogen legacy speakers. The SA-25 can power up to 25 Bogen or Valcom speakers (equal
to 25 “Valcom Power Units”), if no Viking SA series two wire speakers are used.
If a combination of Viking SA series two wire speakers and Bogen or Valcom
speakers are used, the SA-25 can power up to a combined total of 25 speakers.
Larger systems can be achieved by adding Viking model SA-X12 for more Viking
SA series two wire speakers, and/or adding a Bogen or Valcom 24V power sup-
ply for more 4 wire speakers.
