Cardioid Arrays with NOMOS LT
The subwoofer NOMOS LT is designed so that it can be used as a cardioid and hypercardioid
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 (cardioid) or in the lateral side area (hypercardioid),
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.

Setup instructions for a cardioid array
To achieve a cardioid or hypercardioid 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 stacked or flown rear-facing while both other
subwoofers are front-facing.
You can stack the subwoofers even when they are facing opposite directions, and you can
connect them to front-facing systems.
There is an additional Speakon connector on the front grille so that you can connect the
cables to the rear-facing side of all subwoofers in a cardioid array.
You can choose from the following options for cardioid and hypercardioid setups:
