6.2 Cardioid�Arrays�with�NOMOS�LS
The subwoofer NOMOS LS is designed so that it can be used as a cardioid system in an array of three
subwoofers, or in multiples of three.
A cardioid array results in an increase of sound pressure towards the front because of the rear-facing
subwoofer. In the rear area, on the other hand, the sound pressure is clearly reduced.
With this, you achieve
• less unwanted sound on the stage
• low feedback
• simplified miking
• improved room acoustics with fewer reflections from the rear and side walls, or – when flown –
from the ceiling
• simplified adherence of sound emission limits and therefore less noise disturbance for nearby
residential areas during open air events.
6.2.1 Setup�instructions�for�a�cardioid�array
To achieve a cardioid pattern, you must always have an array with 3 subwoofers - or a multiple of 3
subwoofers - setup next to one another (3, 6, 9, etc.). In this set of three, the middle one must be
rear-facing while both other subwoofers are front-facing.
You can choose from the following options for cardioid and hypercardioid setups:
3 x NOMOS LS horizontal
3 x NOMOS LS vertical
3 x NOMOS LS horizontal stacked
3 x NOMOS LS vertical stacked
