Cardioid Array - LD Systems STINGER G3 SERIE Manual De Usuario

CARDIOID ARRAY

The CARDIOID DSP preset is a sophisticated DSP program that makes it possible to attain a cardioid dispersion pattern by combining three
Stinger G3 subwoofers.
This results in the following advantages in comparison with conventional subwoofer setups:
-a rear attenuation of up to 20 dB
-enhanced bass presence in the audience area
-avoidance of unwanted reflections from rear walls
-reduction of diffuse sound in rooms
-elimination of bass frequency interference onstage
-differentiated sound for onstage monitoring
-reduction of the risk of feedback when using stage microphones
Use only Stinger G3 subwoofers of the same type for cardioid setups. Align 3 subwoofers in a row as shown, with the middle subwoof-
er directed towards the rear. Select the CARDIOID preset for the middle subwoofer and the preset with a 100 Hz low-pass filter for the
forward-facing subwoofers. The same audio signal must be present at all subwoofers used for a cardioid setup and the MAIN LEVEL setting
must be identical.
