PowerZone 252 is a 2x125 Watt power amplifier in a half width, 1U format

The PowerZone 252 is a 2 x 125 Watt power amplifier in a half width, 1U format. It drives both low impedance (4Ω to 16Ω) and constant voltage (70V/100V) loudspeaker loads. Each output channel can be independently configured to drive either Lo-Z or Hi-Z and automatic power sharing enables the total 250 Watts to be shared proportionately across the 2 output channels.

With a small form factor and just 1.9kg – it’s a powerful amplifier for its size and can be installed in locations where others cannot.

Key Features

  • Configure any output in Low or High impedance – share total power as you need it
  • DIP Switches allow you to configure on site – with GPIO connectors for external controllers
  • Ultra-compact form factor means it can be installed in spaces where others cannot
  • Class leading energy efficiency and long-term low cost of ownership
  • Powered by Pascal UMAC™ Class-D technology
