Blaze by Sonance PowerZone Amplifiers

Introduction

The Blaze by Sonance PowerZone amplifiers are designed to provide configurable, consistent, and reliable high-performance audio power amplification for commercial and entertainment applications. This manual provides essential information for installation and operation. For any questions regarding configuration, installation, or operation, please contact the appropriate customer support portal.

Product Overview

This document details the PowerZone 252, PowerZone 504, and PowerZone 1004 amplifiers. These amplifiers support both conventional low impedance (Low-Z) and constant voltage (70V/100V - Hi-Z) loudspeaker loads. Key features include automatic power sharing technology, front panel gain controls, status indicators, and rear panel DIP switch configuration for various operational settings. The amplifiers are operational as soon as mains power is connected and are designed for rack mounting, desk mounting, or free-standing placement, with adequate ventilation being crucial for optimal performance.
