CARDIOID PRESET
The �ardioid pre�et m��t �e ��ed in a ��� array o� three �W121HLA. T�o �ox m��t �e oriented to�ard� the a�dien�e and one m��t �e t�rned in
the oppo�ite dire���on (typi�ally the �ox in the �entre o� the array). The �ottom and the top �oxe� m��t ha�e the �TAN�AR� PRE�ET, the �ox in
the middle m��t ha�e the CAR�IOI� PRE�ET. The a�dio �ignal �ent to all �oxe� i� the �ame.
The CAR�IOI� PRE�ET ha� the �ame re�pon�e o� the �TAN�AR� PRE�ET, ��t to o�tain the maxim�m �an�ella��on on the �a�k �ide o� the array it
ha� the pha�e in�erted and a proper le�el and delay �etting.
The fig�re �elo� �ho�� t�o typi�al di�pla�ement o� the array. The fir�t �ith all the �oxe� in horizontal po�i��on �or a total height o� 1770 mm and
a �idth o� 801 mm. The �e�ond one �ith all the �oxe� in �er���al po�i��on �or a total height o� 801 mm and a �idth o� 1770 mm.
NOTES:
When placing the cardioid array keep a distance to walls or other obstacles of at least 80 cm (2.7 ft) in order not to affect the radiation of the
reversed cabinet.
When placing multiple cardioid arrays keep a distance between them of at least 120 cm (3.9 ft) in order not to maximize the combined radiation
of whole arrays.
