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

PowerZone series
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.
- Configure any output in Low or High impedance – complete flexibility of power options
- Power sharing technology delivers versatile power output for each install
- 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
- Blaze Audio is powered by ultra-reliable Pascal UMAC™ Class-D technology
