Note 1:
Mount the
PSA-IP
close to where the
other speakers are installed to minimize the
speaker wire run lengths.
Note 2:
Using half the recommended distance
or half as many speakers per run will keep the
volume lost limited to 3db.
Note 3:
Doubling up the wires will allow double
the length, or reduce the amount of volume
loss.
Note 4:
Heavier gauge wire, fewer speakers
per run, and shorter runs will all minimize
volume loss.

ire Gauge Size
Number of 8 Ohm Speakers on
Each of the Two Wire Runs
Maximum recommended length (in feet) for the number of 8 Ohm speakers on a wire pair to maintain
a volume loss of less than 5dB. Once the length limit has been reached for the wire gauge used, if
additional speakers are needed, start back at the
PSA-IP
with a 2nd parallel wire run. If the length limit
is reached again, start a 3rd run, etc. See
DOD 895
for an example.
