Mackie SP260
Speaker Processor
The Mackie SP260 Speaker Processor is also useful for folks utilizing powered loudspeakers and
subwoofers. Here, the SP260 is configured using the '2xStereo+Subs' setup type. The left and right
line-level XLR outputs from a Mackie ProFX12 mixer feed the A and B XLR inputs of a Mackie SP260
Speaker Processor. XLR outputs 1 and 2 of the Mackie SP260 Speaker Processor feed the XLR inputs
of two Mackie SRM450v2 powered loudspeakers. These loudspeakers are located on stage and
are paired with powered subwoofers as mentioned below.
XLR outputs 3 and 4 of the Mackie SP260 Speaker Processor feed the XLR inputs of two Mackie
TH-15A powered loudspeakers. This full-range pair should be positioned halfway toward the rear of
the venue with delay added, so it syncs with the mains. Or place them in a separate area away from
the stage. Again, beer gardens, for example. Who doesn't like gardening...it's relaxing and looks nice,
right?!
Finally, XLR outputs 5 and 6 of the Mackie SP260 Speaker Processor feed the XLR inputs of two
Mackie SRM1801 powered subwoofers that are located on stage and paired with the SRM450v2
loudspeakers. In this setup, the SP260's high- and low-pass filters on outputs 1 and 2 and 5 and 6 may
be used to configure a crossover between the SRM450v2s and SRM1801s for added control from the
processor. Care should be taken when configuring the SP260's crossover so the SRM1801's built-in
crossover does not conflict. The subs may be stereo or mono by properly configuring the input sources for
SP260 outputs 5 and 6.
The SP260 may be used for additional room corrective EQ and delay to align the loudspeakers
and subwoofers and a limiter added for extra protection against greasy-fingered guest engineers
or irrational DJs.
