Application Diagrams - Mackie M-2600 Owner's Manual

APPLICATION DIAGRAMS

The following pages show some of the more
common uses for the M•2600, including
stereo, mono, and bridged operation.
USING THE LOW CUT FILTER
The application diagrams include some
small graphs of the frequency range going into
and coming out of the amplifier. These graphs
show the effect of the LOW CUT FILTER to roll
off the lower frequencies going to the speakers.

HIGH PASS
The LOW CUT FILTER rolls off the lows be-
low the frequency setting of the rotary control.
It affects the Speaker output and the THRU
output (if the THRU switch is set to HIGH OUT
1k 10k 20k
or LOW OUT).
Hz Hz Hz
Using the LOW CUT FILTER allows you to
tailor the output to the speakers so they re-
ceive only the frequency range they can
handle. For example, if your speakers can
reproduce the frequency range down to
35Hz, set the LOW CUT FILTER to 35Hz. If
your main speakers can reproduce the full
range, then set it to OFF.
In the hookup diagrams on pages 9–12 and
page 15, this small icon is used to indicate that
the lows have been rolled off by using the LOW
CUT FILTER.
Note: Page 14 and 16 show the use of the in-
ternal CROSSOVER.
FULL PASS
This icon indicates that the full frequency
range is passed, either to the speakers or to the
THRU outputs. In the pages that follow, this
also indicates a full-range signal coming from
your mixer or preamp.
LOW PASS
This icon indicates that the highs have been
rolled off. The low-pass range is available if you
use the internal CROSSOVER, discussed in
more detail on page 13, with some application
diagrams on pages 14, 15, and 16.
