Storm Audio PA 8 Ultra MK 2 Multi Channel Power Amplifier



Built upon StormAudio’s robust and high performance MK1 generation, the PA MK2 range shines with its new refined and classier appearance.

The result of a close collaboration with Danish company Pascal Audio, the Class D technology embedded reflects the StormAudio’s philosophy of reliable, controllable and impressive sounding products.

With its UMACTM Class D technology, the PA MK2 range demonstrates audiophile performance with high efficiency, high dynamic range and very low distortion. With four individual URECTM technology-based power supplies, each PA MK2 offers up to 3kW of power capacity with instantaneous response, adapting in real time to the demanding dynamic of cinema soundtrack reproduction.

If high power is required in your installation, you will find the solution in the PA 8 ULTRA MK2. This model, offering up to 800W in Bridge Tied Load mode, is capable of driving any demanding loudspeaker or subwoofer to be found in a modern residential cinema.

When partnered with our ISP products, all PA MK2 status information becomes accessible to the installer within the ISP WebUI interface thanks to StormMonitoring technology, allowing for a total visibility of the installation, whether locally or remotely.

All in all, the PA MK2 range delivers a without compromise offering to power any installation.
