Blaze Audio PowerZone 504 500 W 4-Channel Install Amplifier

The PowerZone 504 is the non-networked counterpart to the Connect 504, fitting four amplifier channels and 500 watts of total system power into a half-rack chassis. In low impedance it produces 4 x 125 W into 4 or 8 ohms; in constant voltage it produces the same 4 x 125 W at 70V or 100V, with power sharing up to 2 x 250 W across outputs so a lightly loaded zone does not waste capacity. Power consumption is rated at 150 W.

With no DSP or web interface to configure, it is a drop-in choice for restaurants, retail, and small commercial zones where the routing and processing already happen upstream and the amplifier just needs to deliver clean, reliable power.
