The Sonance PowerZone 504 is a 4-channel non-networked Class-D installation amplifier engineered for projects that need affordable, reliable audio power across multiple zones without the overhead of a networked DSP platform. Each of the four output channels is independently switchable between Lo-Z (4-16 ohm) and Hi-Z (70V/100V) operation, letting one chassis simultaneously drive low-impedance background speakers and constant-voltage lines.

Power-sharing technology proportionally distributes the amplifier's total available power across channels, ensuring program-dependent material gets the headroom it needs without wasting capacity on quieter zones. The compact half-rack chassis fits desks, closets, AV cabinets, and tight rack spaces where a 1U amplifier would be too wide, and the optional rack ears, surface, and rear-support kits adapt the 504 to nearly any install location.

Backed by a 5-year warranty, the PowerZone 504 ships ready for universal deployment.

The PowerZone 504's combination of multi-mode operation and intelligent power-sharing delivers more usable system flexibility than fixed quad-channel amplifiers at the same price point. Specify rack-mount, surface-mount, or rear-support hardware separately to complete the installation.
