The PowerCube Measuring System

Our latest system lets you test all your new audio amplifier constructions, conventional or Class D.

Do you think Class D is the solution for stability? You'd better check it before you go into production! For several decades it has been common knowledge that a loudspeaker is all but an 8 ohm resistor. Playing an 8 ohm speaker may hit the amplifier with impedances as low as 2 ohms, and with severe phase shifts as well - both capacitive and inductive.

"What Is A PowerCube?"

"A PowerCube is a unique piece of test equipment that measures an amplifier's output voltage across 20 impedances from 1 to 8 ohms. Developed by AudioGraph, the PowerCube adheres strictly to the IHF 202 signal standard to create informative three-dimensional (3D) graphs of voltage versus impedance and phase at a single frequency, typically 1 kHz."
(The Clarion Product Training Manual)
