2.Connect the two RCA inputstogether usinga Y-adaptor,
and then-feed the single
RCA input to a mono signalsource,
suchasthe low pass
(subwoofer)output of an
electronic crossover.
3.Connect the woofer(s)
to the speaker
terminalsas
follows: The positive
connection
of the woofer(s) to thre
lett positive(+) output, and the negative connection of the
woofer(s) to the right negative (-) output.
NOTE: In mono operation, the right positive (+) and left negative (-) speaker terminals have
no connections made to them.

The USA2O5O, USA2OZ!, USA.ZIOrO, and USAZI5O may be used in mixed mono/stereo mode
(For
USA2O5OH, mixed mono usage
with crossover
in "FLAT" positiononly).
Thismeansthat you may run
