Blaze Audio PowerZone 252 250W 2-Channel Power Amplifier

The PowerZone series of install power amplifiers are designed to provide versatile and reliable high-performance audio power.

Each output channel can be independently configured to drive either Lo-Z or Hi-Z loads - making it so much more flexible and versatile than other full rack products. This means a system can be easily configured with any power output, and drive both Lo-Z and Hi-Z loudspeakers - from just one clever amplifier.

Total available power is automatically shared across channel pairs - thanks to our power sharing technology (*252 and 504 models only). The ultra-compact PowerZone can be installed in locations where other products cannot - and has desk and wall mount brackets as well as full rack supports.

PowerZone is a robust and energy-efficient amplifier, that offers quick set-up and custom configuration options, and like all PowerZone products, this reliable, high-performance amplifier has a 5-year warranty.
