INTRODUCTION

Suitable for portable sound reinforcement or xed installations, the series features 2 models that deliver between 300W

and 500W per channel into a 4 ohm load in a rugged 2U, 19” rackmount enclosure. An advanced SMPS (Switched Mode

Power Supply) and Class AB topology deliver high power with low distortion in a compact and lightweight form factor.

A full suite of protection includes thermal, over and under voltage, over-current, DC, short circuit protect and power on/off
mute. The WX Series features XLR inputs and link outputs with a maximum input level of +22dBu allowing integration

with any typical professional audio system. A variable speed fan keeps the amplier rack quiet when not in use. The
WX series features a built in in switched 100Hz LPF/HPF on each channel, allowing the amplier to drive a bi-amplied

system without any external processing.
