18.NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
CAUTION: Changes or modifications to this device not expressly
approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.
19.This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.

radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.
20.Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility 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 the following chart.
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 recommended that all
persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here:

Introduction
Thank you for choosing the Mackie HD1501 subwoofer. Mackie HD Series Powered Subwoofers
provide intense low-frequency extension and punch to
any Mackie full-range system. Designed and tuned by
the experts at EAW, HD1501 subs deliver 1200W peak
power via high-output 15” drivers custom-designed for
optimal pairing with Mackie full-range loudspeakers.
The HD1501 incorporates Mackie-standard professional
components like efficient Class-D Fast Recovery™ amplifiers and system-optimizing Active electronics so
that everything sounds great right out of the box.
Premium circuitry includes a symmetrical LinkwitzRiley crossover, precision tuning filters and user-friendly
features like high pass outputs for stereo operation with
a single sub. The 15mm birch plywood enclosures feature a ported, direct-radiating design for chestpounding punch. Pair the HD1501 with any Mackie full-range loudspeaker for an extremely powerful and
fully high-definition PA solution.
Paired with a Mackie HD1521, you have a complete
(and completely affordable) “plug and play” system that
is ideal for small clubs, DJs and rehearsal spaces. It is
also a great match when paired with the popular Mackie
SRMv2 Series and can easily integrate into nearly any
existing PA setup. The HD1501 has both full-range and
high-pass stereo outputs for connection to full-range
top boxes. Just dial in the appropriate level and use the
polarity switch to make sure the sub is in phase with the
loudspeakers. The integrated pole-cup can accommodate a standard mounting pole, so your favorite speaker has a nice place to sit. Or you can just
stack your full-range box right on top of the sub...the
HD1501 ain’t picky.
So if you are looking for an extremely powerful, affordable PA setup that is simple to use, then you’re in
the right place. Read on to learn everything you could
possibly want to know about your new subwoofer.

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.

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.
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.
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
AVIS: RISQUE DE CHOC ELECTRIQUE — NE PAS OUVRIR
subwoofer. The frequency WARNING:

100 Hz is sent to
these line-level output jacks.
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.
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.
6. POLARITY INVERT
Press this switch in to invert subwoofer polarity.
Depending on the placement of the HD1501 subwoofer

subwoofer’s signal. See page 10 for more information.
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR
MOISTURE. DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
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.
The level control and polarity switch have no effect

control will affect the sig/limit indicator.
The HD1501 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 HD1501 returns to normal
operation.
The HD1501 has a built-in limiter that helps to prevent 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.
Excessive limiting may lead to overheating, which in turn trips the thermal
protect circuitry and interrupts the performance. See ‘Thermal Considerations’ on
page 11 for more information.

HD1501
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 literally pumping air as the woofer cone moves in and out
with respect to the cabinet in which it is housed. It does
so according to the low-frequency portion of the signal it
receives from the sound source.
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
musical signal is much more complex, of course, but the
same principle applies. Movement of the woofer cone
causes air pressure changes that we perceive as sound.
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.
The polarity invert switch comes into play when the
HD1501 subwoofer is paired with a loudspeaker. Ideally,
the woofer cones of the subwoofer and full-range loudspeaker 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
of full-range loudspeakers. The flexibility provided by
the polarity switch is necessary to ensure that you are
receiving the best possible sound from your system,
regardless of your setup.
Listed below are some recommended configurations
for pairing a Mackie HD-Series subwoofer (using the
High-Pass output) with a Mackie full-range loudspeaker. These settings are a good start, but be sure
to experiment to find the best sound for your venue. The
loudspeakers may be stacked, pole-mounted, or flown.
• HD-Series full-range loudspeakers - Disengage the Polarity Invert switch on the HD1501.
• SRM450v2 full-range loudspeakers - Disengage the Polarity Invert switch on the HD1501.
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.

AC Power
The HD1501 subwoofer is designed to sit on the floor
or stage. A socket is provided on top of the HD1501 for
mounting other Mackie loudspeakers. Use the optional
Mackie speaker mounting pole to mount them on the
HD1501. See the hookup diagrams starting on page 4.
Be sure the HD1501 is plugged into an outlet that
is able to supply the correct voltage specified for your
model. It will continue to operate at lower voltages, but
will not reach full power.
Check to make sure that the support surface (e.g.,
floor, etc.) has the necessary mechanical characteristics to support the weight of the loudspeaker(s) and
subwoofer(s).
When pole-mounting loudspeakers, be sure that the
HD1501 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.
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.
The cabinet has no rigging points and is not
suitable for rigging. Never attempt to suspend
the HD1501 by its handles.
Thermal Considerations
The HD1501 has a powerful built-in amplifier capable
of producing 600 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.
The amplifier module is cooled by twin thermally-controlled vari-speed fans. In order for this
convection cooling system to work efficiently, it is
important to provide adequate airspace behind the subwoofer. When positioning the HD1501, we recommend leaving at least six inches of air space
behind it.
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.
Owner’s Manual
Placement
Never remove the ground pin on the power
cord or any other component of the HD1501.
This is very dangerous.
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.
• 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.
• 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 cabinet, particularly where the driver is located.
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 HD1501 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 HD1501) to avoid overheating the amplifier. Be aware that direct sunlight
and/or hot stage lights may be the cause of an amplifier
overheating.

Service Information
If you think your Mackie product has a problem,
please check out the following troubleshooting tips and
do your best to confirm the problem. Visit the Support
section of our website (www.mackie.com/support)
where you will find lots of useful information such as
FAQs and other documentation. You may find the answer
to the problem without having to send your Mackie
product away.
Troubleshooting
No power
• Check the polarity of the connections between
the mixer and the subwoofers. You may have
your positive and negative connections reversed
at one end of one cable, causing one subwoofer
to be out-of-phase.
• Check your subwoofer polarity switches are
configured appropriately for your setup. See
page 10 for more information.
Poor sound
• Is it plugged in? Make sure the AC outlet is live
(check with a tester or lamp).
• 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.
• Our next favorite question: Is the power switch
on? If not, try turning it on.
• Is the input connector plugged completely into
the jack? Be sure all connections are secure.
• 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” below.
• 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 next.
No sound
• Is the input level control for the input source
turned all the way down? Verify that all the
volume controls in the system are properly
adjusted.
• Is the signal source working? Make sure the
connecting cables are in good repair and
securely connected at both ends. Make sure the
output volume (gain) control on the mixing
console is turned up sufficiently to drive the
inputs of the speaker.
• 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 indicator lit red on the rear
panel? Make sure there is at least six inches of
free space behind the HD1501.

Poor bass performance
HD1501
Noise
• Make sure all connections to the powered subwoofers are good and sound.
• Make sure none of the signal cables are routed
near AC cables, power transformers, or other
EMI-inducing devices.
• Is there a light dimmer or other SCR-based
device on the same AC circuit as the HD1501?
Use an AC line filter or plug the HD1501 into a
different AC circuit.
Hum
• Try disconnecting the cable connected to the
main input jack. If the noise disappears, it
could be a “ground loop,” rather than a problem
with the HD1501. Try some of the following
troubleshooting 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.

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 example, if your mixer has an output impedance of 120 ohms,
then you can daisy chain up to nine HD1501s. This is
a load of 1222 ohms (HD1501 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 HD1501s (assuming that loudspeakers are also connected to the subwoofers).
