Mackie DLM12 Owner's Manual

Owner’

s Manual

DLM loudspeakers have powerful system processing

tools built in. Simply press the system [SYS] button
repeatedly until the parameter you want to change is
highlighted:

•  EQ
•  Delay
•  FX
•  Feedback

Once the parameter you want to change is

highlighted, press the + or – button [16] repeatedly
until you have achieved the setting you want for the
loudspeaker system.

Let’s take a more detailed look at each of the four

factory system preset parameters:

Here you are able to change the loudspeaker’s

speaker mode to tailor it to best suit your particular
application. There are seven modes, including PA, DJ,
Soloist, Monitor, EQ K, EQ Y and EQ J.

PA Speaker Mode – This mode is full range, but

focuses on mid-range clarity where vocals often reside.

DJ Speaker Mode – This mode bumps the lows and

highs with a mild tuck to the mids, perfect for music
playback.

Soloist Speaker Mode – This mode features a low

frequency roll-off to get rid of unwanted thumps  
and adds boost and sparkle to mid-range and high
frequencies. This mode is perfect for plug-and-play
singer-songwriters.

Monitor Speaker Mode – This mode features a low

frequency roll-off and a reduction around 2 kHz to
ensure maximum gain before feedback in monitor  
applications.

KYJ Speaker Modes – These modes mimic the  

voicings of popular competitive loudspeakers, allowing
you to add Mackie DLM loudspeakers to an existing
system while maintaining sonic continuity throughout
the system.

Delay “delays” the audio signal for a set period of

time. With DLM loudspeakers, it’s used for aligning
delay stacks, balcony fills, etc, not as an effect. DLM
delay times range from 0 ms [0.0 feet / 0.0 meters]
to 300 ms [337.8 feet / 102.9 meters].

DLM loudspeakers include 16 “gig ready” effects,

including various reverbs, delays, choruses and

combinations of these, as well. Select your preferred
effect from the list then return to channel 1 or 2 [11] to
adjust the appropriate level for each source.

Be sure to check out a more detailed description of

each effect in Appendix D.

The multi-band Feedback Destroyer hunts down

offending feedback frequencies and applies up to six
notch filters automatically to destroy feedback and
maximize gain prior to feedback. This is a great tool for
when an engineer is not present.

There are four Feedback Destroyer settings to choose

from:

Off [Default] – The Feedback Destroyer is not

engaged. If filters have been applied, this setting will
retain its current filter settings if there are any, but they
will not be engaged until it is turned back on. This is
indicated by the grayed out filter graphic.

On – When the automatic Feedback Destroyer is

turned on, scanning occurs continuously. The six filters
will engage sequentially when feedback is present until
all are used and then it will be locked. If feedback is
identified on an existing filter, the notch will deepen in
three steps to further destroy the offending feedback
frequency. Pretty cool, huh?!

Clear – This clears all filters.

Hold – Hold allows a user to turn off the continuous

scan. In this mode, filters that have been applied are
still on, but the circuit is no longer looking for feedback.
