Eq Setup - Mackie DRM12A Owner's Manual

Now that you're hungry, let's take a look at what
opening the sub menu really displays:
• Off – Choose this if there is no subwoofer
connected to the system. Here you are using
a DRM12A loudspeaker only.
• DRM Sub – Choose this if a Mackie DRM18S
subwoofer is connected to the system. The crossover
point is set to 90 Hz to work in perfect harmony with
the Mackie DRM18S Sub. This is what we hope you
choose, thank you for your support!
• Var – Choose this if a non-Mackie DRM18S
subwoofer is connected to the system. Here you
can select the subwoofer's HPF, ranging from
40 Hz – 160 Hz.
Rotate the speaker control knob until the sub HPF
you desire is illuminated, then push to select it.
If var is selected (as seen below), the frequency
is illuminated and may be changed by rotating the
speaker control knob clockwise (raise the frequency)
and counter-clockwise (lower the frequency).

In addition to the three sub modes, there's a fourth
and final selection: the left-facing arrow. Illuminating
and selecting this simply returns you to the menu.

EQ Setup

On to the bottom row now! The first one listed
is EQ, and, as you might expect, this is where
to adjust the output EQ.
The DRM12A has 3-band EQ with shelving hi, peaking
mid and shelving low. Shelving means that the circuitry
boosts or cuts all frequencies past the specified
frequency. Peaking means that certain frequencies
form a "hill" around the center frequency.
we know that everyone will occasionally need that.
But if you max the EQ, you'll get mix mush.
In order to change the EQ, first push the speaker
control knob when the EQ icon is illuminated
(see image above). This opens the EQ view:

From here, rotate the speaker control knob until
the parameter you want to change is illuminated.
Push the speaker control knob in to select the

knob clockwise (raise the gain / frequency)
and counter-clockwise (lower the gain / frequency).

EQ DELAY
With too much EQ, you can really upset
things. We've designed a lot of boost
and cut into the equalizer circuit because
