Introducing Power Surge - Surge Audio's flagship series of high power amplifiers. These models were designed from the ground up, to be anything other than average. PS Series amplifiers feature a military-grade PCB with the most copper tracing possible, added standoffs for extreme vibration resistance, and overbuilt transformers to withstand the heaviest of abuse.

Cooling is key. The PS Series heatsink was custom tooled to optimize cooling capacity. We made use of thermal modeling to determine the best possible heat dissipation capacity of our heatsink options. Beyond that, we have spaced the mounting feet 1/4" below the heatsink to allow for additional airflow below the backplate of the amplifier.

All PS Series amplifiers include silver plated Tiffany style RCA inputs, four-stage intelligent protection circuitry, and a remote bass knob with clipping, voltage, and temperature indication.
