22. Rigging Precautions: When mounting or suspending loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. Use
only the mounting/rigging points on the loudspeaker enclosure
intended for this purpose. The user must determine the load requirements, dynamic loading, and any other contributing factors
affecting the loudspeaker installation. The user must determine the
proper design factor for specific applications and the required load rating of the connection to structure. Comply with all applicable
federal, state, and local regulations.
We strongly recommend the following rigging system practices:
• Documentation: Thoroughly document the mounting/rigging
design with detailed drawings and parts lists.
• Analysis: Have a licensed structural engineer or other qualified
professional review and approve the mounting/rigging design
before its implementation.
• Installation: Use personnel experienced and qualified for mounting/rigging loudspeakers in accordance with and in
compliance with all federal, state and local regulations.

This simple system may be utilized in a variety of ways anywhere high-output and easy setup are needed. Great
for wedding DJs to vocal reinforcement to full band PA, the HD1221 is the perfect setup when you need a highoutput, ultra-portable PA.
In this example, the left and right main outputs from a mixer feed the MAIN INPUTs of a pair of Mackie HD1221
powered loudspeakers.
Note: HD1221s do not necessarily need to be pole-mounted. They may be placed on a floor, stage, or other
firm surface or they may be flown for permanent installs. Please refer to pages 9-12 for more information on

Similar to the previous hookup diagram, this one adds some low end to your portable PA. It is perfect for the
same setups as mentioned previously [sound reinforcement, weddings, vocal reinforcement, portable PA for a full
band of all genres, etc.], as well as for DJs and other functions that call for additional low-end thump. This is the
perfect setup when you need an ultra-portable PA with A LOT of output!
In this example, the left and right main outputs from a mixer feed the inputs of a pair of Mackie HD1501 powered subwoofers. HIGH PASS OUTPUT A of each subwoofer feed the MAIN INPUTs of the Mackie HD1221
powered loudspeakers. The HD1221s reproduce the mid-to-high frequencies in stereo, and the subs provide the
low frequencies in stereo.
If just a little extra low end is needed, a single HD1801 may be used with a pair of HD1221s and still retain a
stereo image.

This is the perfect setup for using HD1221s as high output, professional stage monitors. This type of setup may be
utilized at local clubs, festival stages, in churches and more.
In this example, AUX SENDS 1-3 from a mixer feed the MAIN INPUTS of three Mackie HD1221 powered loudspeakers which lay across the front of the stage as monitors for the band. Additionally, a fourth Mackie
HD1221 powered loudspeaker is daisy-chained by using the LOOP OUT XLR jack from one of the other monitors, providing two monitors off of a single aux send. See page 15 [‘Appendix B: Connections’] for details
on how to daisy-chain loudspeakers.
The left and right main outputs from the same mixer feed the MAIN INPUTs of the house PA speakers. See the
hook-up diagram on the previous page [‘HD1221: 3-way system with powered subwoofers’] to see how to connect the mixer to the PA.

3. VOICING MODE
This built-in 3-position voicing mode switch allows the
HD1221 to be tailored for any sound application.
CONTOUR
Set the Voicing Mode switch to the ‘CONTOUR’ position for low-level applications. This is the perfect setting when a little more low and high end is necessary. The LED next to the switch will illuminate yellow when ‘CONTOUR’ is the chosen voicing mode.
NORMAL
This is the standard position of the switch, hence the name, ‘NORMAL’. It is ideal for most PA applications where the HD1221 will be
cranked. Additionally, this is the recommended position when paired with a subwoofer. Of the three options, this is the most accurate voicing mode and should be used in the majority of applications. The LED next to the switch will illuminate green when ‘NORMAL’ is the chosen voicing mode.
MONITOR
The ‘MONITOR’ position is designed for when the HD1221 will be used as a stage monitor, but it may also be utilized when you need the vocals to cut through a high-gain, high-output instrument (such as guitar). In this position, the low frequency is rolled off, while the mids and highs are tuned to cut through stage volume with as much gain before feedback as possible. The LED next to the switch will illuminate red when ‘MONITOR’ is the chosen voicing mode.

7. LEVEL
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.
This controls the overall signal level at the input to
the built-in power amplifiers. It ranges from –6 dB to +6 dB of gain. The center detent is 0 dB (unity gain).
Use this control to vary the level of the HD1221 versus
other loudspeakers and subwoofers in your system. Be
sure to keep an eye on the SIG/LIMIT LED [6].
If this switch is disengaged [out], and the HD1221 is
powered on, the LED on the front of the cabinet will not
light, nor will the LED next to the switch. The LED next
to the POWER Switch [8] and other rear panel LEDs
will still illuminate when the unit is powered on.
5. THERMAL LED
The HD1221 is equipped with a thermal protection
circuit that monitors the internal temperature of the
amplifiers and heatsink. If the temperature exceeds a
safe operating level, this indicator lights and the input
signal is muted to allow the amplifiers to cool. When the
temperature cools to a safe level once again, the thermal
protection circuit deactivates, the THERMAL LED turns
off and the HD1221 returns to normal operation.
When the HD1221 is in thermal protect mode, the
unit is still powered on despite the lack of output. If
POWER LIGHT ON [4] is engaged, the front panel
power LED will go out when in thermal protect mode.
Activation of the thermal protection circuit
is an indication that you should take steps
to avoid continued thermal problems. See ‘Thermal Considerations’ on page 13 for more information.
6. SIG/LIMIT LED
This bi-color LED illuminates green whenever there is
a signal present at the MAIN INPUT connector. It senses
the signal just after the LEVEL control, so adjustments
to the LEVEL control will affect the SIG/LIMIT indicator.
The HD1221 has a built-in limiter that helps to prevent the amplifier outputs from clipping or
overdriving the transducers. The SIG/LIMIT indicator lights 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 level
control 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 13
for more information.

HD1221
8. POWER
Use this switch to turn the HD1221 on and off. The
LED next to the switch will illuminate when powered
on. The front panel LED will also turn on, but only if the
POWER LIGHT ON switch [4] is engaged.
Press the bottom of this switch to put the speaker into
standby mode. The HD1221 will not function, but the
circuits are still live. To remove AC power, either turn
off the AC mains supply, or unplug the power cord from
the speaker and the AC mains supply.
As a general guide, the powered speakers
should be turned on last, after the mixer and
other sources. They should also be the first
things turned off. This will reduce the possibility of any
turn-on, or turn-off thumps in your speakers.
9. IEC AC Receptacle
This jack accepts the supplied ­3-prong AC power cord.
Before you plug the AC power cord into the
powered loudspeaker, make sure that the
voltage of your unit (listed above the IEC AC
receptacle) 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.
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 loudspeaker is installed in a stable and secure way in
order to avoid any conditions that may be dangerous for
persons or structures.
The HD1221 speaker is designed to sit on the floor or
stage as the main PA or as monitors. It may also be polemounted via the built-in socket on the bottom of the
cabinet. Be sure the pole is capable of supporting the
weight of the HD1221. The Mackie SPM200 is a great
option when using a sub. The HD1221 may also be flown
horizontally or vertically via its 12 integrated fly points
as detailed on page 11.
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).
When pole-mounting loudspeakers, be sure that they
are stabilized and secured from falling over or being accidentally pushed over. 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 loudspeaker in places
exposed to harsh weather conditions. If you are setting
them up outdoors, make sure they are under cover if you
expect rain.
You can create a horizontal array by placing the cabinets side-by-side. However, you should have a good
understanding of the relationship between the splay
angle (the angle between the facing sides of the cabinets) and frequency cancellation effects between
cabinets.
When two cabinets are positioned side-by-side such
that the rear-angled faces of the enclosures are
parallel, the splay angle will be 90º. This matches the 90˚ horizontal coverage pattern of each individual
HD1221; the interference between the two cabinets will
be minimized, but the total coverage of 180˚ may be too
wide for some applications (see Figure A). The mid and
high frequencies may also be reduced for those in the
center who are too close to the loudspeakers.
Owner’s Manual
Placement
Reducing the splay angle will reduce the total
horizontal coverage, but it also creates an area both
speakers are covering. Instead of a nearfield hole,
this will cause comb-filtering effects in the frequency
response in the overlapping area. The smaller the splay
angle, the more energy will be delivered on-axis, but the comb-filtering effects will get worse at the same time
(see Figure B).
Experimentation and experience will help you find
the right trade-off for your application. In the end, the
correct placement will depend on the environment and
the necessary audience coverage.

HD1221
Room Acoustics
The HD1221 loudspeakers are designed to sound neutral; that is, to reproduce the input signal as accurately as possible.
Room acoustics play a crucial role in the overall
performance of a sound system. Here are some additional placement tips to help overcome some typical
room problems that might arise:
• Avoid placing loudspeakers in the corners of
a room. Doing so increases the low frequency
output and can cause the sound to be muddy
and indistinct.
• Highly reverberant rooms, like many
gymnasiums and auditoriums, are a nightmare for sound system intelligibility.
Multiple reflections off the hard walls, ceiling,
and floor play havoc with the sound. Depending
on the situation, you may be able to take some
steps to minimize the reflections, such as putting carpeting on the floors, closing draperies to cover large glass windows, or
hanging tapestries or other materials on the
walls to absorb some of the sound.
However, in most cases, these remedies are not
possible or practical. So what do you do?
Making the sound system louder generally
doesn’t work because the reflections become
louder, too. The best approach is to provide as
much direct sound coverage to the audience
as possible. The farther away you are from
the speaker, the more prominent will be the
reflected sound.
Use more speakers strategically placed so they
are closer to the back of the audience. If the
distance between the front and back speakers
is more than about 100 feet, you should use a
delay processor to time-align the sound. (Since
sound travels about 1 foot per millisecond, it
takes about 1/10 of a second to travel 100 feet.)
• Avoid placing loudspeakers against a wall. This,
too, increases the low frequency output, though
not as much as corner placement. However, this
is a good way to reinforce the low frequencies,
if so desired.
• Avoid placing the speakers directly on a
hollow stage floor. A hollow stage can resonate
at certain frequencies, causing peaks and dips
in the frequency response of the room. It is better to place the loudspeakers on a sturdy
stand designed to handle the weight of the
HD1221.
• Position the loudspeakers so the high-
frequency drivers are 2 to 4 feet above ear
level for the audience (make allowances for a
standing/dancing in the aisles audience). High
frequencies are highly directional and tend to
be absorbed much easier than lower frequencies. By providing direct line-of-sight
from the loudspeakers to the audience, you
increase the overall brightness and
intelligibility of the sound system.

HD1221
Keep in mind that the VOICING MODE switch is a
great way to compensate for some of these issues. See
page 7 for more information.
Rigging
HD1221s may be individually flown horizontally or
vertically 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 loudspeaker is installed in a stable and secure way in
order to avoid any conditions that may be dangerous for
persons or structures.
WARNING: The cabinet is suitable for rigging
via its fly points. NEVER attempt to suspend
the HD1221 by its handles.
Rigging Design Practices
Rigging a loudspeaker requires determining:
Owner’s Manual
Rigging Hardware and Accessories
Rigging Mackie loudspeakers 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.
Mackie does offer certain accessory rigging items,
primarily for attachment to the hardware integral with
the loudspeaker. Some items, such as eyebolts and
U-brackets, 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.

system for supporting the loudspeaker from structure.
Mackie strongly recommends the following rigging
practices:
Rigging Notes
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.
4. Safety: Use adequate safety precautions and back-up systems.

The HD1221’s intergral mounting points are designed
to support only the weight of their own loudspeaker
with suitable, external hardware. This means that each
HD loudspeaker must be supported independently of
any other HD loudspeaker and any other loads.
A minimum of two rigging points must be used to hang
an HD1221. More may be used for creating the desired
hanging angle as shown in the illustrations on the following page. All mounting points are fully load bearing so any two may be used for rigging; no mounting
points are restricted to angle control only.

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, loadcertified rigging system for supporting the loudspeaker
from structure.
The illustrations provided below are just a couple of
rigging possibilities.

Care and Maintenance
The HD1221 has two powerful built-in amplifiers
capable of producing a combined 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.
Your Mackie loudspeakers will provide many years of
reliable service if you follow these guidelines:
The amplifier module is mounted on a large heatsink,
which is cooled by convection where cool air is drawn
through its fins, carrying the heat away. In order for this
convection cooling to work efficiently, it is important
to provide adequate airspa
