Product Description
The Blaze Audio PowerZone™ 1004 is a high-performance, 4-channel, 1,000 W installation amplifier engineered for professional audio systems in commercial, institutional, and architectural settings. Combining compact form, robust reliability, and flexible connectivity, the PowerZone 1004 addresses the demands of fixed installations where space, efficiency, and adaptability matter.
With each output channel independently configurable for low-impedance (Lo-Z) or high-impedance (70V / 100V Hi-Z) operation, this amplifier enables a single unit to drive a mix of conventional and line-level distributed speakers. The unit is based on Pascal UMAC™ Class-D topology, delivering clean, efficient power with minimal heat dissipation. A rear 8-position DIP switch allows granular configuration of channel mode, front-panel gain lock, input mode, and standby logic. For remote control, a GPIO interface supports external potentiometer or control logic for volume adjustment and standby switching.
Designed with installation flexibility in mind, the PowerZone 1004 occupies just 1U of rack height and includes bracket options for rack, shelf, wall, or under-desk mounting. It is ErP / Energy Star compliant, consumes ~300 W at full load, and enters a low-power standby mode (< 0.5 W) when not in use. Blaze backs this amplifier with a 5-year warranty, making it a dependable choice for long-term installations.
This amplifier is ideal for environments such as restaurants, retail stores, hotels, corporate boardrooms, educational campuses, fitness centers, houses of worship, and other venues requiring compact, reliable, and flexible audio distribution.
