The OLED Display is one of the most vital features

of the DLM12S subwoofer. It displays subwoofer
information including (but not limited to) volume,
selected crossover, delay settings and other parameters.

When a DLM12S subwoofer is powered up, the last

state it was in will load up and the OLED Display will
present the volume screen and settings.

DLM12S subwoofers will display a running Running

Man screensaver if parameters haven’t been changed in
awhile. Simply touch one of the DLP buttons to “wake
up” the OLED Display.

Volume [VOL] adjusts the overall signal level at the

inputs to the built-in amplifiers. Press the VOL button  
to access and update the subwoofer’s volume and
change the volume by pressing the + or – button [16]
repeatedly until you have reached the desired volume.
The volume ranges from off (–  dB) to +10 dB.

The DLM12S crossover [XVR] allows you to choose

from a list of preset crossover frequencies for Mackie
loudspeakers, as noted below. This optimizes the  
subwoofer and loudspeakers connected to the  
DLM12S high pass outputs. If not using DLM or SRM
loudspeakers, a variable mode allows you to select
the best crossover frequency suited for your PA system
from 60 Hz to 120 Hz.

Frequencies below the selected crossover frequency

are sent to the subwoofer while frequencies above the
selected crossover frequency are sent to the high pass
outputs [6]. The crossover frequency should be set
to the lowest frequency response rating of the main
loudspeakers. Press the XVR button repeatedly until  
the desired crossover setting is highlighted.

•  DLM8 : 110 Hz
•  DLM12 : 90 Hz
•  SRM350 : 100 Hz
•  SRM450 : 95 Hz
•  Variable : 60 Hz – 120 Hz

The last one listed – variable – may be set to taste.

Simply press the + or – button [16] repeatedly until
you have achieved the crossover point you desire.  
It ranges from 60 Hz to 120 Hz.

Pressing the VOL [10] and XVR [11] buttons

simultaneously gives you the option to turn the front
LED on, off or limit. Press the + or – button [16] to
make a choice, followed by any other button to exit the
screen. Choosing limit means the LED is on full-time.
However, it will flicker when the limiter is active  
[3 dB of attenuation, averaged].

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

time. With the DLM12S subwoofer, it’s used for aligning
delay stacks, balcony fills, etc, not as an effect.

Press the DLY button to access and update the

subwoofer’s delay. Change the delay by pressing  
the + or – button [16] repeatedly until you have
reached the desired delay. Delay times range from
0 ms [0.0 feet / 0.0 meters]to 300 ms [337.8 feet /
102.9 meters].

Settings for DLM subwoofers may be saved to memory

and recalled at a later time by utilizing the memory
[MEM] button.

Press this button repeatedly until the preset spot

you want to save settings to (or recall settings from) is
highlighted. There are three user presets and a fourth
to recall the factory default settings.

Once the preset you want to save to (or recall from)

is highlighted, press the “+” button [16] to save the
current settings or press the “–” button to recall a
preset that was previously saved.
