Use this switch to turn the HD1801 on and off. The
LED above the switch will illuminate when powered on.
The front panel LED will also turn on, but only if the
POWER LIGHT ON switch (7) is engaged. Press the
bottom of this switch to turn the subwoofer off.
This jack accepts the supplied 3-prong AC power cord.
Before you plug the AC power cord into the
powered subwoofer, make sure that the
voltage of your unit is the same voltage as your
local AC mains supply. Use only the power
cord supplied. Also, disconnecting the plug’s ground pin
is dangerous. Don’t do it.
As a general guide, powered subwoofers
should be turned on after the mixer and other
sources, but prior to full-range speakers.
Additionally, they should also be powered off
after the tops, but before the mixer and other sources.
This will reduce the possibility of any turn-on, or turn-
off thumps in your speakers.

5. FULL RANGE OUTPUTS
These female XLR connectors accept balanced
line-level signals from a mixing console or other signal
source.
Balanced XLR male connectors are provided for the
line-level A and B full-range outputs. Connect these
outputs to the inputs of another powered subwoofer,
main powered loudspeakers, or to an amplifier powering
passive loudspeakers.
If you are connecting a single subwoofer output, or
LFE (low-frequency effects) output to the subwoofer,
you may use either the A or B input connector.
The signal at these outputs is a direct copy of the
input signals. These outputs allow you to daisy-chain
multiple subwoofers, and/or send the full-range signals
to the main loudspeakers.
CAUTION: NEVER connect the output of an
amplifier directly to the input of the
subwoofer. This could damage the input
circuitry of the powered subwoofer.
The level control and polarity switch have no effect
on the full-range outputs. The outputs are separate and
maintain the stereo separation of the input signals.
4. HIGH PASS OUTPUTS
Balanced XLR male connectors are provided for the
line-level A and B high-pass outputs. The subwoofer’s
internal active crossover splits the input signals into
two frequency bands. The low frequency range below
100 Hz goes to the internal amplifier that powers the
subwoofer. The frequency range above 100 Hz is sent to
these line-level output jacks.
6. POLARITY INVERT
Press this switch in to invert subwoofer polarity.
Depending on the placement of the HD1801 subwoofer
relative to the full-range speakers, you may get a better
low-frequency response if you invert the polarity of the
subwoofer’s signal. See page 11 for more information.
Connect these outputs to the inputs of your main
powered loudspeakers, or to the inputs of the amplifier
powering the main loudspeakers. In this way, the main
loudspeakers will play the range above 100 Hz. If the
main loudspeakers have good low-frequency response,
then you may decide to use the full-range outputs (5)
instead.
7. POWER LIGHT ON
Press this switch in to turn on the front panel power
LED if a visual indicator is preferred. The LED next to
the switch will light as a reminder.
If this switch is out, and the HD1801 is turned on, the
LED on the front of the cabinet will not light, nor will
the LED next to the switch.
The level control and polarity switch have no effect
on the high-pass outputs. The outputs are separate and
maintain the stereo separation of the input signals.
8. LEVEL
This controls the overall signal level at the input to
the built-in power amplifier. It ranges from –6 dB to
+6 dB of gain. The center detent is 0 dB (unity gain).
This control has no effect on the level of the High
Pass Outputs (4) or the Full Range Outputs (5).

This bi-color LED illuminates green whenever there is
a signal present at the main inputs. It senses the signal
just after the level control, so adjustments to the level
control will affect the sig/limit indicator.
The HD1801 is equipped with a thermal protection
circuit that monitors the internal temperature of the
amplifier and heatsink. If the temperature begins to
exceed a safe operating level, this indicator lights and
the amplifier output is limited to allow the amplifier to
cool. If the amplifier becomes excessively hot, the amp is
muted until it cools, then the HD1801 returns to normal
operation.
The HD1801 has a built-in limiter that helps to pre-
vent the amplifier outputs from clipping or overdriving
the transducer. The sig/limit indicator lights in yellow
when the limiter is activated. It’s okay for it to blink
yellow occasionally, but if it blinks frequently or lights
continuously, turn down the input level until it only
blinks occasionally.
When the HD1801 is in thermal protect mode, the
power LED (2) will remain lit, indicating that the unit
is still powered on despite the lack of output. If POWER
LIGHT ON (7) is engaged, the front panel power LED
will go out when in thermal protect mode.
Excessive limiting may lead to

The Ins and Outs of Polarity
Mackie’s HD-Series Powered Subwoofers include a
switch that allows you to quickly invert the polarity of
the subwoofer’s output relative to the input signal it is
receiving from the mixer or other sound source. But
what exactly does that mean? A subwoofer works by lit-
erally pumping air as the woofer cone moves in and out
The polarity invert switch comes into play when the
HD1801 subwoofer is paired with a loudspeaker. Ideally,
the woofer cones of the subwoofer and full-range loud-
speaker would work together by pushing and pulling in
unison. HD-Series subwoofers are designed to be used
in a broad range of applications, and with a wide variety
with respect to the cabinet in which it is housed. It does of full-range loudspeakers. The flexibility provided by

receiving the best possible sound from your system,
regardless of your setup.
The woofer cone is simply following the waveform
as seen in the sine wave in Figure 1. As the sine wave
rises, the woofer cone pushes out. Likewise, as the sine
wave falls, the woofer cone pulls into the cabinet. A

to experiment to find the best sound for your venue. The
loudspeakers may be stacked, pole-mounted, or flown.
When the Polarity Invert switch [6] is engaged, the
original waveform is simply reversed 180º (see Figure
2). Again, the subwoofer cone follows the waveform.
However, this time the woofer cone starts by pulling into
the cabinet followed by the woofer cone pushing out. If
you have ever experimented with a subwoofer polarity
switch, you may not have noticed any changes to the
sound regardless of its position, especially if you are
listening to just the subwoofer. This is normal, as our
ears perceive them both as the same.
• HD-Series full-range loudspeakers - Engage the
Polarity Invert switch on the HD1801.
• SRM450v2 full-range loudspeakers - Disengage the
Polarity Invert switch on the HD1801. Engage the
Low Cut Filter switch on the SRM450v2 loudspeaker.
In alternate setups where the full-range loudspeakers
are not co-located with the subwoofers or are not
connected to the HD-Series subwoofer’s High-Pass
outputs, you will need to experiment with the Polarity
Invert switch to determine which setting gives you the
desired bass response for your application.

Rigging Hardware and Accessories
Rigging
Rigging Mackie subwoofers will invariably require
hardware not supplied by Mackie. Various types of
load-rated hardware are available from a variety of
third-party sources. There are a number of such
companies specializing in manufacturing hardware for,
designing, and installing rigging systems. Each one of
these tasks is a discipline in its own right. Because of
the hazardous nature of rigging work and the potential
liability, engage companies that specialize in these
disciplines to do the work required.
HD1801s may be individually flown using M10 x 1.5 x
37 mm forged shoulder eyebolts.
WARNING: Installation should only be done
by an experienced technician. Improper
installation may result in damage to the
equipment, injury or death. Make sure that the
subwoofer is installed in a stable and secure way in
order to avoid any conditions that may be dangerous for
persons or structures.
Mackie does offer certain accessory rigging items,
primarily for attachment to the hardware integral with
the subwoofer. Some items, such as eyebolts, may be
used with a variety of products. While these accessories
are intended to facilitate installation, the wide variety of
possible installation conditions and array configurations
do not permit Mackie to determine their suitability or
load rating for any particular application.
WARNING: The cabinet is only suitable for
rigging via its fly points. NEVER attempt to
suspend the HD1801 by its handles.
Rigging Design Practices
Rigging a subwoofer requires determining:
1. The rigging methods and hardware that meet static,
shock, dynamic, and any other load requirements for
supporting the subwoofer from structure.
Mackie is not in the business of providing complete
rigging systems, either as designers, manufacturers, or
installers. It is the responsibility of the installer to
provide a properly engineered, load-certified rigging
system for supporting the subwoofer from structure.
2. The design factor for and the required WLL
(Working Load Limit) for this support.
Mackie strongly recommends the following rigging
practices:
Rigging Notes
The HD1801’s integral mounting points are designed
to support only the weight of their own subwoofer,
or in combination with (1) one HD-Series full-range
loudspeaker, with suitable, external hardware. This
means that each HD subwoofer, alone or paired with an
HD-Series full-range loudspeaker, must be supported
independently of any other HD subwoofer and any other
loads.
1. Documentation: Thoroughly document the design
with detailed drawings and parts lists.
2. Analysis: Have a qualified professional, such as a
licensed Professional Engineer, review and approve the
design before its implementation.
3. Installation: Have a qualified professional rigger do
the installation and inspection.
A minimum of two rigging points must be used to hang
an HD1801. More may be used for creating the desired
hanging angle as shown in the illustrations on page 12.
All mounting points are fully load bearing so any two
may be used for rigging; no mounting points are
restricted to angle control only.
4. Safety: Use adequate safety precautions and
back-up systems.

Important Rigging Reminder:
To reiterate, Mackie is not in the business of providing
complete rigging systems, either as designers,
manufacturers, or installers. It is the responsibility of
the installer to provide a properly engineered, load-cer-
tified rigging system for supporting the subwoofer from
structure.

Be sure the HD1801 is plugged into an outlet that
subwoofers may be flown. However, they are designed to is able to supply the correct voltage specified for your
sit on the floor or stage, as well. A socket is
provided on top of the HD1801 for mounting other
Mackie loudspeakers. Use a suitable speaker mounting
pole to mount them on the HD1801. See the hookup
diagrams starting on page 4.
model. It will continue to operate at lower voltages, but
will not reach full power.
Be sure the electrical service can supply enough
amperage for all the components connected to it.
We recommend that a stiff (robust) supply of AC
power be used because the amplifier places high
current demands on the AC line. The more power that is
available on the line, the louder the subwoofer will play
and the more peak output power will be available for a
cleaner, punchier bass. A suspected problem of “poor
bass performance” is often caused by a weak AC supply
to the amplifier.
Check to make sure that the support surface (e.g.,
floor, etc.) has the necessary mechanical characteris-
tics to support the weight of the loudspeaker(s) and
subwoofer(s).
When pole-mounting loudspeakers, be sure that the
HD1801 subwoofers are stabilized and secured from
falling over or being accidentally pushed over. For
stacked scenarios, it is highly suggested that straps are
utilized. Failure to follow these precautions may result
in damage to the equipment, personal injury, or death.
Never remove the ground pin on the power
cord or any other component of the HD1801.
This is very dangerous.
As with any powered components, protect them from
moisture. Avoid installing the subwoofer in places
exposed to harsh weather conditions. If you are setting
them up outdoors, make sure they are under cover if you
expect rain.
Care and Maintenance
Your Mackie subwoofers will provide many years of
reliable service if you follow these guidelines:
•
Avoid exposing the subwoofers to moisture. If
they are set up outdoors, be sure they are under
cover if rain is expected.
Thermal Considerations
The HD1801 has a powerful built-in amplifier capable
of producing 800 watts of rms power. As an amplifier
works, it produces heat. The higher the signal level, the
louder and hotter it gets. It is important to dissipate the
heat as quickly as possible. This results in increased
reliability and longevity for the amplifier.
•
Avoid exposure to extreme cold (below
freezing temperatures). If you must operate the
subwoofers in a cold environment, warm up the
voice coils slowly by sending a low-level signal
through them for about 15 minutes prior to
high-power operation.
The amplifier module is cooled by twin
•
Use a dry cloth to clean the cabinets. Only do
this when the power is turned off. Avoid getting
moisture into any of the openings of the cabi-
net, particularly where the driver is located.
thermally-controlled vari-speed fans. In order for this
cooling system to work efficiently, it is important to
provide adequate airspace behind the subwoofer. When
positioning the HD1801, 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, muting the
amplifier’s output. When the amplifier has cooled down
to a safe operating temperature, the thermal switch
resets itself, and the HD1801 resumes normal operation.
If the thermal switch activates frequently, try turning
down the level control a notch or two on the mixing
console (or the back of the HD1801) to avoid
overheating the amplifier. Be aware that direct sunlight
and/or hot stage lights may be the cause of an amplifier
overheating.

with the HD1801. Try some of the following
troubleshooting ideas:
•
Use balanced connections throughout your
system for the best noise rejection.
•
•
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.
•
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.
Is the thermal indicator lit red on the rear
panel? Make sure there is at least six inches of
free space behind the HD1801.

The HD1801 has two female XLR inputs that accept
balanced line-level signals. When connecting a balanced
signal, be sure it’s wired per AES (Audio Engineering
Society) standards:
Non-warranty service for Mackie products is

Balanced XLR Connectors

Pin 1 – Shield (Ground)
Pin 2 – Hot (+)
Pin 3 – Cold (–)
There are also two male XLR connectors on the
HD1801 labeled full range. These are also wired
according to the AES standards listed above.
The full range connectors allow you to connect
several HD1801’s. Simply plug the signal source
(e.g., mixer output) into the HD1801 input jack, and
patch that subwoofer’s full range jack to the next
subwoofer’s input jack, and so on, daisy-chaining
multiple subwoofers.
There is a limit to how many you can
daisy-chain together. A general rule is to
maintain a load impedance ten times or
more than the source impedance to prevent
excessive loading on the source. For exam-
ple, if your mixer has an output impedance of 120 ohms,
then you can daisy chain up to nine HD1801s. This is
a load of 1222 ohms (HD1801 input impedance=11
kohms; 9 of these in parallel=1222 ohms). Since
microphones typically have a higher output impedance,
you should limit daisy-chaining from a mic source to two
HD1801s (assuming that loudspeakers are also con-
nected to the subwoofers).
