1 INTRODUCTION
Thank you for your purchase of this Ashly
nX
,
nXe
, or
nXp
multi-mode power amplifier. Each speaker output can be config
-
ured for low impedance (2, 4, or 8 Ohm), or 25V, 70V, or 100V constant voltage output. This amplifier uses state of the art,
light weight, high power, high efficiency switching technology with active power-factor-correction, developed through years
of design and field testing. NX amplifiers are available in the following three series, designed to meet the most demanding live
sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
