According to OSHA, any exposure in excess  
of these permissible limits could result in some  
hearing loss. To ensure against potentially dan-  
gerous exposure to high sound-pressure levels,  
it is recommended that all persons exposed to  
equipment capable of producing these levels use  
hearing protectors while this unit is in opera-  
tion. Ear plugs or protectors in the ear canals or  
over the ears must be worn when operating this  
amplification system in order to prevent a per-  
manent hearing loss if exposure is in excess of  
the limits set forth here.  
Exposure to extremely  
high noise levels may  
cause permanent hear-  
ing loss. Individuals vary  
considerably in suscepti-  
bility to noise-induced hearing loss, but nearly  
everyone will lose some hearing if exposed to  
sufficiently intense noise for a period of time.  
The U.S. Government’s Occupational Safety and  
Health Administration (OSHA) has specified  
the permissible noise level exposures shown in  
this chart.

INTRODUCTION  
M•1400i and C300z. 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 sub-  
woofer 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,  
dramatically extending life expectancy, and  
eliminating maintenance cycles. A tremendous  
benefit of having the amplifier located within the  
subwoofer cabinet is that the SWA1801z functions  
as a system, optimizing acoustic, electronic, and  
mechanical designs to achieve the highest level of  
performance and value.  
Thank you for choosing Mackie’s active  
sound reinforcement speaker systems.  
The SWA1801z is a high-output active sub-  
woofer system. It features a high-precision 18"  
transducer 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 SWA1801z is  
a breeze. It accepts a stereo or mono line-level  
signal via female XLR input jacks. Male XLR  
Thru jacks are provided for daisy-chaining the  
signal to additional SWA1801z cabinets. The  
built-in crossover separates the low frequencies  
from the high frequencies, and routes the high  
frequencies to the male XLR high-pass output  
jacks. Connect these to the inputs of full-range  
active speakers such as the Mackie SA1521z,  
or to an amplifier powering a pair of passive  
speakers such as a combination of the Mackie  
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 to the rear for easy transport.

REAR PANEL DESCRIPTION  
POWER Switch  
POWER Indicator  
Use this switch to turn the SWA1801z on  
and off. Make sure the signal source’s level  
control is turned down before you turn it on.  
When the POWER switch is turned on  
and the linecord is connected to an active  
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.  
AC Receptacle  
This is where you connect the AC linecord  
to provide AC power to the SWA1801z’s  
built-in power amplifiers. Plug the linecord  
into an AC socket properly configured for  
your particular model.  
FULL RANGE INPUT  
These are female XLR-type connectors  
that accept a balanced line-level signal from  
a mixing console or other signal source.  
LIMIT Indicator  
THRU (FULL RANGE OUTPUT)  
The SWA1801z has a built-in limiter that  
prevents the amplifier outputs from over-  
driving the transducers. The LIMIT indicator  
lights when the limiter is activated. It’s okay  
for the LIMIT indicator to blink occasionally,  
but if it blinks frequently or lights continu-  
ously, turn down the level control until the  
LIMIT indicator only blinks occasionally.  
These are male XLR-type connectors  
that produce exactly the same signal that is  
connected to the FULL RANGE INPUT jack.  
Use it to daisy-chain several SWA1801z's  
together off the same signal source.  
HIGH PASS (MID/HIGH FREQ) OUTPUT  
These are male XLR-type connectors  
that produce the frequencies above 120Hz.  
Connect these to a pair of full-range active  
speakers or to an amplifer/passive speaker  
combination. The SWA1801z reproduces  
the frequencies below 120Hz.  
SIGNAL Present Indicator  
This LED illuminates whenever there is  
a signal present at the FULL RANGE INPUT  
connector on the rear panel.  
THERMAL Indicator  
SUBWOOFER LEVEL Control  
The SWA1801z has a thermal protection  
circuit that monitors the internal tempera-  
ture of the amplifiers and heatsink. If the  
internal temperature should exceed a safe  
operating level, this indicator lights and the  
signal is muted to allow the amplifier to cool.  
When the temperature cools to a safe level  
once again, the thermal protection circuit  
deactivates and normal operation resumes.  
Note: Activation of the thermal protection  
circuit is an indication that you should take  
steps to avoid continued thermal problems.  
See “Thermal Considerations” on page 7.  
This adjusts the subwoofer level. The  
center detent position provides 15 dB of  
headroom with a nominal +4 dBu input  
signal. Use this as a starting point for setting  
the balance between the subwoofer and the  
main speakers.  
PHASE  
This switch reverses the polarity of the  
subwoofer output. Depending on the place-  
ment of the SWA1801z subwoofer relative  
to the full-range speakers, you may get a  
better low-frequency response in the room  
if you reverse the polarity of the subwoofer’s  
signal. Experiment with this switch to de-  
termine which position sounds best.

CONNECTIONS  
The THRU output connectors allow you  
to connect more than one SWA1801z to  
your system. Simply plug the signal source  
(i.e., mixer output) into the first speaker’s  
FULL RANGE INPUT jacks, and patch that  
speaker’s THRU jacks to the next speaker’s  
INPUT jacks, and so on, daisy-chaining mul-  
tiple speakers.  
The THRU jack is wired straight from the  
FULL RANGE INPUT connector — there is no  
electronic circuitry between — so the signal  
coming out of the THRU jack is exactly the  
same as the signal going in.  
The SWA1801z has two female XLR in-  
puts that accept a balanced line-level signal.  
When connecting a balanced signal, be sure  
it’s wired per AES (Audio Engineering  
Society) standards:  
XLR  
Hot (+)  
Cold (–)  
Shield (Ground)  
Pin 2  
Pin 3  
Pin 1  
The HIGH PASS OUTPUT jacks provide  
a line-level signal of the frequencies above  
120Hz that you connect to a pair of active  
speakers (or to a stereo amplifier powering  
a pair of passive speakers).  
PLACEMENT  
The SWA1801z subwoofer is designed  
to sit on the floor. A socket is provided on  
the top of the SWA1801z for mounting  
the Mackie SA1521z or SRM450 active  
speakers. Use the optional Mackie speaker  
mounting pole (SPM100) to mount them  
on the SWA1801z (see Hookup Diagram on  
page 5).  
Balanced XLR Connectors  
If connecting an unbalanced signal to the  
SWA1801z balanced input, be sure that the  
signal high (hot) connection is wired to Pin  
2 and the unbalanced ground connection  
is wired to the low and the ground connec-  
tions of the balanced input (Pins 3 and 1).  
If there are ground-loop problems, try con-  
necting the unbalanced ground connection  
only to the input low connection (Pin 3),  
and leaving the input ground connection  
disconnected.  
As with any powered  
components, protect the  
SWA1801z from exposure  
to moisture. If you are  
setting them up outdoors,  
make sure they are under  
cover if you expect rain.  
There are also four male XLR connectors  
labeled THRU (FULL RANGE OUTPUT) and  
HIGH PASS (MID/HIGH FREQ) OUTPUT  
.
These are also wired according to the  
AES standard.  
WARNING: The cabinet  
has no rigging points and  
is not suitable for rigging.  
NEVER attempt to sus-  
pend the SWA1801z by  
its handles.

AC POWER  
If the thermal switch activates frequently,  
try turning down the level control a notch  
or two on the mixing console (or other  
signal source) or on the subwoofer itself to  
avoid overheating the amplifiers.  
If the temperature in the room is too  
high, it could cause the amplifier to over-  
heat. In this case, you should try aiming  
a fan at the rear panel to move more air  
across the heatsink panel.  
Be sure the SWA1801z is plugged into  
an outlet that is able to supply the correct  
voltage specified for your model. If the volt-  
age should drop below 97% of the specified  
line voltage, the built-in amplifiers will no  
longer be able to supply rated power. (They  
will continue to operate down to 80% of  
the rated line voltage, but won’t reach full  
power, resulting in lower headroom.)  
Be sure the electrical service can supply  
enough amperage for all the components  
connected to it.  
We recommend that a stiff (robust)  
SERVICE INFORMATION  
supply of AC power be used because the  
amplifiers place high current demands on  
the AC line. The more power that is avail-  
able on the line, the louder the speakers  
will play and the more peak output power  
will be available for cleaner, punchier bass.  
A suspected problem of “poor bass per-  
formance” is often caused by a weak AC  
supply to the amplifiers.  
Warranty Service  
Details concerning warranty service are  
spelled out on page 11 of this manual.  
If you think your subwoofer has a  
problem, please do everything you can  
to confirm it before calling for service,  
including reading through the following  
Troubleshooting section. Doing so might  
save you from being deprived of your Mack-  
ie loudspeaker.  
Of all Mackie products returned for  
service (which is hardly any at all), many  
are coded “CND” — Could Not Dupli-  
cate— which usually means the problem lay  
somewhere else in the system. The follow-  
ing troubleshooting tips may sound obvious,  
but here are some things you can check:  
Never remove the ground  
pin on the power cord  
of the SWA1801z or any  
other component. This is  
very dangerous.  
THERMAL  
Troubleshooting  
CONSIDERATIONS  
No power  
The SWA1801z has a powerful 800 watt  
amplifier built-in. As amplifiers produce  
heat, it is important to dissipate the heat as  
quickly as possible. This results in increased  
reliability and longevity for the amplifier.  
The amplifier module is mounted on  
a large heatsink, which is cooled by con-  
vection where cool air is drawn through it’s  
fins, carrying the heat away. In order for  
this convection cooling to work efficiently,  
it is important to provide adequate airspace  
behind the loudspeaker. When you position  
the SWA1801z, we recommend leaving at  
least six inches of air space behind it.  
In the unlikely event of the amplifier  
overheating, a built-in thermal switch will  
activate, which mutes the signal. When the  
amplifier has cooled down to a safe oper-  
ating temperature, the thermal switch resets  
itself, and the SWA1801z resumes normal  
operation.  
• Our favorite question: Is it plugged in?  
Make sure the AC outlet is live (check  
with a tester or lamp).  
• Our next favorite question: Is the POWER  
switch on? If not, try turning it on.  
• Is the POWER LED on the rear panel  
glowing green? If not, make sure the AC  
outlet is live. If so, refer to “No sound”  
next.  
• The internal AC line fuse may be blown.  
This is not a user serviceable part. If you  
suspect the AC line fuse is blown, please  
see the “Repair” section on page 9.

No sound  
Noise  
• Is the input LEVEL control for the input  
source or the subwoofer turned all the  
way down? Verify that all the volume  
controls in the system are properly ad-  
justed.  
• Make sure all connections to the active  
loudspeakers are good and sound.  
• Make sure none of the signal cables are  
routed near AC cables, power trans-  
formers, or other EMI-inducing devices.  
• Is the signal source working (and making  
union scale)? Make sure the connecting  
cables are in good repair and securely  
connected at both ends. Make sure the  
output volume (gain) control on the mix-  
ing console is turned up sufficiently to  
drive the inputs of the speaker.  
• Is there a light dimmer or other SCR-  
based device on the same AC circuit as  
the SWA1801z? Use an AC line filter or  
plug the SWA1801z into a different AC  
circuit.  
Hum  
• Make sure the mixer does not have a  
Mute on or a Processor loop engaged. If  
you find something like this, make sure  
the volume/gain is turned down before  
disengaging the offending switch.  
• Is the thermal protection circuit activated?  
Make sure there is at least six inches of  
free space behind the SWA1801z.  
• Try disconnecting the cable connected  
to the INPUT jack. If the noise disap-  
pears, it could be a “ground loop,” rather  
than a problem with the SWA1801z.  
Try some of the following troubleshoot-  
ing ideas:  
• Use balanced connections throughout  
your system for the best noise rejection.  
• Whenever possible, plug all the audio  
equipment’s linecords into outlets which  
share a common ground. The distance  
between the outlets and the common  
ground should be as short as possible.  
Poor bass performance  
• Check the polarity of the connections  
between the mixer and the loudspeak-  
ers. You may have your positive and  
negative connections reversed at one  
end of one cable, causing one loudspeak-  
er to be out-of-phase.  
• Try switching the PHASE switch on  
the rear panel. This affects the polarity  
between the full-range speakers and the  
SWA1801z and may improve the low-  
frequency response.  
Poor sound  
• Is it loud and distorted? Make sure that  
you’re not overdriving a stage in the  
signal chain. Verify that all level controls  
are set properly.  
• Is the input connector plugged  
completely into the jack? Be sure all con-  
nections are secure. It’s a good idea to  
periodically clean all electrical connec-  
tions with a non-lubricating electrical  
contact cleaner.
