Dual mono - P49 only
Dual mono requires the use of a power amplifier for
each channel.
We recommend that you use the
set
SPEAKER 1 L
of terminals on your P49 power amps for the low
frequencies and the
SPEAKER 2 R
set of terminals for the
high frequencies.
On one of the P49's, connect the red positive speaker
terminal labelled
to the positive
terminal

of your right speaker. Similarly, connect the black
negative speaker terminal labelled
to the
SPEAKER 1 L-
negative
terminal of your right speaker. Repeat this
LF
process for the left speaker, using the terminals labelled
and
on the other P49 power amp.
