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:

MEMSYS21
2000WDigital Loudspeaker
DLM loudspeakers are the perfect tool for singer-songwriters touring the local coffee shops.
Bring your favorite axe and mic, DLM loudspeakers and cables and power cords.
Compact and portable perfection.
In this example, a dynamic microphone is connected to the channel 1 input of a DLM12 loudspeaker.
Be sure that the mic/line switch is down in order to get an extra 30 dB boost for the mic. Be sure the
switch is OUT if anything other than a microphone is attached to the channel 1 input. Adjust the level
and EQ, as described on page 12.
Now grab your axe and plug it directly into the channel 2 input. Or if you use effects, connect the guitar
to the effects input and another cable from the effects output to the channel 2 input. Adjust the level and
EQ for the guitar now.
An additional DLM8 or DLM12 loudspeaker is great for monitoring. Simply connect a cable from the
main DLM loudspeaker’s THRU jack to the monitor loudspeaker’s channel 1 input [mic/line switch OUT!].
Also, make sure the Ch 1/Mix switch is down on the main DLM, as well, so a mix of the vocals and
guitar is relayed to the monitor. Release the kickstand for a perfect angle
For the output, you will want to set a speaker mode, described in detail on page 13. For this type of
setup, PA works well for the main DLM12. However, don’t count out the soloist mode! It has a nice low cut
and a brilliant high end. Select the monitor mode for the DLM12 monitor. Lastly, you can ring out before
you play, utilizing the DLM’s feedback destroyer [page 13] or just let it kill the feedback while playing.

PROFESSIONALMIC/LINE MIXER WITH FX
In this example, a Mackie DLM12S subwoofer and additional DLM loudspeaker have been added to the
mix, giving our sound system a little extra beef. 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 on page 13. 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.

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 on page 13. 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.

DLM loudspeakers may be daisy-chained via the male XLR connector labeled “THRU”. Simply plug the
signal source (i.e., mixer output) into the input jack(s), and patch that loudspeaker’s THRU jack to the next
loudspeaker’s input jack, and so on, daisy-chaining multiple DLM loudspeakers. See above for a visual
representation of daisy-chaining.
The THRU jack on DLM loudspeakers 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 loudspeakers indefinitely. If you do that, we want pictures!

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 on page 13. 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.
