This amplifier receives the frequency
range above the first amplifier's
CROSSOVER point.
NOTE: Set its LOW CUT FILTER
below the CROSSOVER point of the
first amplifier or you will miss part of
the bass range.
Because the OUTPUT APPLICATION
switch is set to LOW OUT, this
M•2600 plays the frequency range
below the CROSSOVER point (60, 90,
or 120Hz).
Set the LOW CUT FILTER to the
lowest frequency your subwoofers can
handle (or set it to OFF).
Set the THRU switch to HIGH OUT
so the next amplifier will receive the
frequency range above the
CROSSOVER point.
Use the MONO MODE so the
subwoofers play the same and are
always in-phase. Low-frequency sound
is non-directional, so there is no
benefit in playing the subs in STEREO,
in fact, there may be times when the
speakers get out of phase, causing
some bass reduction.
