10. Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or when
unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when
the apparatus has been damaged in any way, such as power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
15. This apparatus shall not be exposed to dripping or splashing, and no object
filled with liquids, such as vases or beer glasses, shall be placed on the
apparatus.
16. Do not overload wall outlets and extension cords as this can result in a risk
of fire or electric shock.
17. This apparatus has been designed with Class-I construction and must be
connected to a mains socket outlet with a protective earthing connection
(the third grounding prong).
18. This apparatus has been equipped with a rocker-style AC mains power
switch. This switch is located on the rear panel and should remain readily
accessible to the user.
19. The MAINS plug or an appliance coupler is used as the disconnect device,
so the disconnect device shall remain readily operable.
20.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

Communications.
ATTENTION —
Le présent appareil numérique n’émet pas de bruits radioélec-
triques 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.
22. 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:

PROFESSIONALMIC/LINE MIXER WITH FX
In this example, a Mackie DLM12S subwoofer is connected to two DLM loudspeakers. It is a perfect setup
for a small club.
Here, the L/R outputs of a Mackie ProFX8 mixer are connected directly to the channel A and B inputs
of a single Mackie DLM12S subwoofer.
The channel A and B high pass outputs of the Mackie DLM12S subwoofer are connected directly to the
channel 1 inputs of each DLM loudspeaker. Be sure the mic/line switch is OUT. Or be ready to be blasted
with an additional 30 dB! Select the DLM12 crossover on the DLM12S for a perfectly matched system
tuning.
DLM loudspeakers are also perfect for using as stage monitors. Simply connect a cable from each aux
send to the channel 1 input of each DLM loudspeaker used as a monitor.
For the output, you will want to set a speaker mode, described in detail in the DLM loudspeaker
manual. For this type of setup, we recommend selecting the PA speaker mode for live sound on your
DLM loudspeakers. If using any DLM loudspeakers as monitors, select the monitor speaker mode.

Hookup Diagrams continued...
Perhaps you’re a DJ playing bumpin’ tunes in the middle of the night to a crowd that’s groovin’
and dancin’ to your fine selection.
In this example, a laptop is connected to the channel 1 and 2 inputs of a Mackie Onyx Blackjack
and a set of headphones are connected to the phones jack.
The L/R monitor outputs of the Mackie Onyx Blackjack are connected directly to the channel A inputs
of each DLM12S subwoofer.
The channel A high pass output of each Mackie DLM12S subwoofer are connected directly to the
channel 1 input of each Mackie DLM loudspeaker. Be sure the mic/line switch is OUT. Or be ready
to be blasted with an additional 30 dB! Select the DLM12 crossover on the DLM12S for a perfectly
matched system tuning.
For the output, you will want to set a speaker mode, described in detail in the DLM loudspeaker manual.
For this type of setup, we recommend selecting either the PA or DJ speaker mode. The DJ speaker mode
has more bass and sparkling high end. Try them both out and go with the one that best suits your needs.

Daisy-Chaining Multiple DLM12S Subwoofers
Hookup Diagrams continued...
DLM12S subwoofers may be daisy-chained via the male XLR connector labeled “FULL RANGE”. Simply
plug the signal source (i.e., mixer output) into the input jack(s), and patch that subwoofer’s full range jack
to the next subwoofers’s input jack, and so on, daisy-chaining multiple DLM12S subwoofers. See above
for a visual representation of daisy-chaining.
The full range jacks on DLM12S subwoofers are fully buffered with 100 balanced output impedance
drivers, so there is no additional loading to the inputs when daisy-chaining. In other words, you
could conceivably daisy-chain DLM subwoofers indefinitely.

Hookup Diagrams continued...
Here’s how to set up a large club system using all Mackie gear. In this example, the L/R outputs of
a Mackie DL1608 mixer are connected directly to the channel A inputs of two DLM12S subwoofers.
The channel A full range outputs of these two DLM12S subwoofers are connected directly to the channel
A inputs of another set of DLM12S subwoofers. Talk about beefy low end, that’s 8000 watts, yo!
And we’ve only connected the subs.
The channel A high pass outputs of the last two DLM12S subwoofers are connected directly to the
channel 1 inputs of the main pair of DLM loudspeakers. Be sure the mic/line switch is OUT.
Or be ready to be blasted with an additional 30 dB! Select the DLM12 crossover on each DLM12S
for a perfectly matched system tuning.
DLM loudspeakers are also perfect for using as stage monitors. Simply connect a cable from an aux
send to the channel 1 input of a DLM loudspeaker. For the aux to monitor output, you will want to set
a speaker mode, described in detail in the DLM loudspeaker manual. Since these are monitors, select the
appropriately named monitor speaker mode.
Select PA speaker mode for the main loudspeakers. You will want
to turn the feedback eliminator ON on all four DLM loudspeakers,
as described in the DLM loudspeaker manual.
