EAW UXA Introduction and Key Features

Introduction

The EAW UXA Series Advanced System Amplifier represents current state-of-the-art technology in several areas. 
This product is the result of several years of research, from which many advances in switched mode power 
technologies and ever finer detail in signal processing have stemmed. Taking advantage of the latest advances 
in analog to digital conversion technologies, the unit achieves performance levels among the very best that 
engineering permits. 

Below is a list of key features, followed by some information on the major advanced features of the product.

Key Features

  –  Four/Eight channels of sonically pure Class D amplification
  –  Very high power density - packs four channels or eight channels and 10kW into just 2U of rack space
  –  Packed with robust protection and monitoring systems to keep the show going
  –  External Breaker Protection (EBP) limits the current draw to prevent breakers opening
  –  EAW minimal signal path design
  –  Class leading sonic performance achieved by the use of state of the art Amplifier technologies and highly  

 

    advanced DSP algorithms
  –  48kHz sampling frequency
  –  Rotary encoders, illuminated buttons and graphical display provide a rapid, intuitive and user-friendly  
    control interface
  –  High speed Ethernet communications supporting DHCP, static-IP and auto-IP and direct connection  
    to a computer
  –  Linear phase HF system EQ profiling which provides perfect integration between enclosures
  –  Dante audio networking with automatic fall over to Analog or AES3
 – AES3 inputs

Greyboxes include:

EAW Focusing

By deploying advanced signal processing EAW Focusing corrects for mechanically 

induced anomalies in the loudspeakers acoustic system and provides a pure 

impulse response.  This means the sound you hear is true to the original version free 

from time smear created by intra-cabinet reflections.

What is a Greybox?

A Greybox is a file that includes everything you need to get optimal performance from an EAW loudspeaker.
‘White’ component that is user accessible. ‘Black’ component that is EAW-provided and locked down.  
Mix together = Grey.
