Array Mode; Sub - Mackie DRM12A Owner's Manual

Array Mode

This array mode allows the DRM12A to be tailored
for any sound application. It's voiced depending on the
number of DRM12As in use and the user-EQ settings.
As more DRM12As are arrayed together, the boxes
couple and the low frequency energy increases.

Rotate the speaker control knob until the array
mode you desire – Single, Dual, 3-4 or 3-4 Long – is
illuminated, then push to select it. As seen below,
we're going with 3-4.
• Single – Choose this if a single Mackie DRM12A
loudspeaker (or one per side) will be used in the setup.
• Dual – Choose this if two Mackie DRM12A
loudspeakers (or two per side) will be used
in the setup.
• 3 – 4 – Choose this if three or four Mackie DRM12A
loudspeakers will be used in the setup.

• 3 – 4 Long – When configuring an array with three
or four DRM12A loudspeakers per side, set the array
mode on the top one or two boxes to 3-4 Long.
Longthrow mode is calculated to account for up
to 100 feet of air loss compensation.
The top box in a flown three or four box array
typically has to reach an audience that is much further
away than those covered by the bottom boxes. Since
high frequency energy decreases as it travels, audience
members positioned towards the rear of the venue will
commonly perceive less high end than those located
closer. 3-4 Long compensates for this by boosting
the top end so the audio sounds smooth and even
when it reaches those audience members.
Therefore, set the array mode to 3-4 Long on the
top one or two boxes in the array. In doing so, the high
frequency energy will reach the back of the venue,
as intended. Setting the bottom boxes to 3-4 (not long)
will cover the audience converged more towards
the front.
Be sure to listen for consistency by using your ears
while walking around the room.
There's also a left-facing arrow. Illuminating
and selecting this simply returns you to the menu.
