Description

Product Description

Features

  • Ultra high definition
  • 4 channel rack mountable power amplifier
  • Specifically designed for optimised performance with ESD loudspeakers, as well as with other passive systems
  • 4 x 1000W / 2Ω
  • Two separate power supplies ensure increased reliability and continuous delivery of full power
  • Two shock mounted fans move air across the fins but never directly across the electronic components. Minimises maintenance cycles and improves the components lifespan and reliability

Applications

Designed to drive the ESD and ESM range of passive loudspeaker units with superior sound quality

  • Portable PA
  • Fixed installations
  • Monitor Amplifier
