Blaze Connect 504: Powerful 500 W, 4-channel DSP amp with hybrid Lo-Z/Hi-Z power, network control, and automatic power sharing in a half-rack 1U design.
The Blaze Audio PowerZone Connect 504 is a robust 500 W Class-D amplifier that delivers exceptional power and flexibility in a small package. Designed for sophisticated commercial audio installations, this amp features a space-saving half-rack, 1U form factor without compromising on performance or control.
This 4-channel amplifier offers highly versatile hybrid power distribution, allowing you to drive conventional Lo-Z (4Ω to 16Ω) loudspeakers and Hi-Z (70V/100V) transformer-coupled systems. The Connect 504 provides impressive output options, including 4 x 125 W in Lo-Z mode or 2 x 250 W in Hi-Z mode. Its innovative automatic power sharing technology allows 250 W to be proportionately shared between each pair of Lo-Z outputs, maximizing efficiency. The unit is built with highly efficient Pascal UMAC™ Class-D technology and a UREC™ universal power supply with PFC, ensuring reliable global operation and adherence to Energy Star/ErP compliance.
System configuration is simple and powerful via the integrated PowerZone™ Control web app. Accessible through a wired or wireless network connection, this platform offers full-matrix DSP configuration, allowing you to manage inputs/outputs, control sound zones, import speaker pre-sets, and access professional tuning settings quickly—all from any standard browser, including your smartphone. Connectivity is comprehensive with four analog inputs, one stereo digital input, S/PDIF input/output, and configurable GPIO for seamless integration with external control systems. The Connect 504 is UL listed and secured by an industry-leading 5-year warranty.
