According to OSHA, any exposure in excess
of these permissible limits could result in some
hearing loss. To ensure against potentially dangerous exposure to high sound-pressure levels,
it is recommend ed that all persons exposed to
equipment capable of producing these levels use
hearing protectors while this unit is in operation. Ear plugs or protectors in the ear canals or
over the ears must be worn when operating this
amplifi cation system in order to prevent a permanent hearing loss if exposure is in excess of
the limits set forth here.

INTRODUCTION
Thank you for choosing Mackie’s ac tive
sound reinforcement speaker sys tems.
The SWA1801 is a high-output active subwoofer system. It features a high-pre ci sion 18"
transducer combined with application-spe cifi c
amplifi er technology. The system is com posed of
a single, com pact subwoofer cab i net with built-in
control and am pli fi er elec tron ics.
Connecting and setting up the SWA1801 is
a breeze. It accepts a stereo or mono line-level
sig nal via fe male XLR input jacks. Male XLR
Thru jacks are provided for daisy-chain ing the
signal to ad di tion al SWA1801 cabinets. The
built-in cross over separates the low fre quen cies
from the high fre quen cies, and routes the high
fre quen cies to the male XLR high-pass output
jacks. Connect these to the in puts of full-range
active speak ers such as the Mackie SA1521s,
or to an amplifi er pow er ing a pair of pas sive
speak ers such as a combination of the Mackie

POWER Switch
Use this switch to turn the SWA1801 on
and off. Make sure the sig nal source’s lev el
con trol is turned down before you turn it on.
AC Receptacle
This is where you connect the AC line cord to provide AC power to the SWA1801’s
built-in power am pli fi ers. Plug the line cord
into an AC sock et prop er ly con fi g ured for
your par tic u lar model.
LIMIT Indicator
The SWA1801 has a built-in limiter that
pre vents the amplifi er outputs from over-
driving the transducers. The

lights when the limiter is activated. It’s okay
for the
LIMIT
indicator to blink oc ca sion al ly,
but if it blinks fre quent ly or lights continuously, turn down the level con trol until the
LIMIT
indicator only blinks occasionally.
SIGNAL Present Indicator
This LED illuminates whenever there is
a signal present at the
FULL RANGE INPUT

THERMAL Indicator
The SWA1801 has a thermal protection
circuit that monitors the internal tem per a ture of the amplifi ers and heatsink. If the
in ter nal temperature should exceed a safe
op er at ing level, this indicator lights and the
sig nal is mut ed to al low the amplifi er to cool.
When the tem per a ture cools to a safe level
once again, the ther mal protection cir cuit
de ac ti vates and normal operation resumes.
Note:
Activation of the thermal pro tec tion
circuit is an indication that you should take
steps to avoid continued ther mal prob lems.

AC power supply, this indicator lights green
to let you know that you’re ready to rock
and roll. The cool blue LED on the front of
the cabinet works in the same way.
FULL RANGE INPUT
These are female XLR-type connectors
that accept a balanced line-level signal from
a mixing console or other signal source.
THRU (FULL RANGE OUTPUT)
These are male XLR-type connectors that
produce exactly the same signal that is con nect ed to the
FULL RANGE INPUT
jack. Use
it to dai sy-chain several SWA1801s to geth er
off the same sig nal source.
HIGH PASS (MID/HIGH FREQ) OUTPUT
These are male XLR-type connectors
that produce the frequencies above 120Hz.
Con nect these to a pair of full-range active
speak ers or to an amplifer/passive speaker
com bi na tion. The SWA1801 reproduces the
fre quen cies below 120Hz.
SUBWOOFER LEVEL Control
This adjusts the subwoofer level. The
cen ter detent position provides 15 dB of
head room with a nominal +4 dBu input
sig nal. Use this as a starting point for set ting
the balance between the subwoofer and the
main speakers.
PHASE
This switch reverses the polarity of the
subwoofer output. De pend ing on the place ment of the SWA1801 subwoofer relative to
the full-range speak ers, you may get a better
low-fre quen cy re sponse in the room if you
re verse the po lar i ty of the subwoofer’s sig nal.

which po si tion sounds best.
