INTRODUCTION
Thank you for choosing Mackie’s active
sound reinforcement speaker systems.
The SWA2801z is a high-output active sub
-
woofer system. It features two high-precision
18" transducers combined with application-
specific amplifier technology. The system is
composed of a single, compact subwoofer cabinet
with built-in control and amplifier electronics.
Connecting and setting up the SWA2801z is
a breeze, even for your brother-in-law. It accepts
a stereo or mono line-level signal via female
XLR input jacks. Male XLR Thru jacks are pro-
vided for daisy-chaining the signal to additional
SWA2801z cabinets. The built-in crossover
separates the low frequencies from the high fre-
quencies, and routes the high frequencies to the
male XLR high-pass output jacks. Connect these
to the inputs of full-range active speakers, or to
an amplifier powering a pair of passive speakers.
A Phase switch gives you the option of reversing
the polarity of the signal to the subwoofer by 180º.
A Subwoofer Level control allows you to adjust
the balance between the subwoofer and the full-
range speakers.
The built-in amplifier produces 800 watts of
continuous power. The amplifier module sits on a
heatsink that eliminates the need for fans, dra-
matically extending the amplifier's life expectancy,
and eliminating maintenance cycles. A tremen-
dous benefit of having the amplifier located within
the subwoofer cabinet is that the SWA2801z func
-
tions as a system, optimizing acoustic, electronic,
and mechanical designs to achieve the highest
level of performance and value.
The cabinet is constructed with 15 mm thick
multi-layered birch plywood. Carrying handles are
integrated into each side for easy loading, and cast-
ers are attached for easy transport.
