(*) 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.

CONNECTORS
The XTMLA cabinets are fitted with a pair of Neutrik Speakon NL8
connectors. All eight pins of both connectors are wired in parallel.
The XTMLA uses the pin assignments 2+/2- for woofer, 3+/3- for
mid-hi section in bi-amp (this configuration) and 4+/4- for high
section in tri-amp. The XTHPS36 uses a pair of NL4 Neutrik Spe-
akon. Pins 1+/1- are assigned to XTHPS36 woofer 1 and 2+/2- to
woofer 2. The double Speakon connector permits parallel con-
nection of a further loudspeaker system of the same type.
