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.
