Array made of 4 bi-amplified elements
with “Big punch” subwoofer
(*) The “Far” output has a boost in the ultra- high frequency zone; to be used for a set of upper modules which are positioned in the top part of the array (suspended or stacked), depending on installation
geometry and environmental conditions (architecture, humidity), to throw the very high frequencies far enough, despite air absorption.

I diffusori XTMLA sono equipaggiati con una coppia di connettori
Neutrik Speakon NL8. Tutti gli 8 poli di ogni connettore sono ca-
blati in parallelo. L’XTMLA usa i poli 2+/2- per il woofer, 3+/3- per
la sezione medio-alti in bi-amplificazione e per la sezione medi
in tri-amplificazione, 4+/4- per la sezione alti in tri-amplificazione.
I subwoofer XTHPS36 utilizzano una coppia di NL4 Neutrik Spea-
kon: i poli 1+/1- del subwoofer XTHPS36 sono dedicati al woofer
1, mentre i 2+/2- al woofer 2.
Il doppio connettore Speakon consente di collegare in parallelo un
diffusore aggiuntivo del medesimo tipo.
