The EPS is a high-precision constant voltage source. The chassis and circuit design are magnetically and capacitatively optimized. The circuit board layout ensures the lowest losses due to oversized current paths and controls the current flow into ground.

The arrangement of the toroid core transformers minimizes the influence of magnetic disturbances. The voltage supply is managed by two 100 VA ring toroid transformers that are each responsible for one half-wave. The capacity of the fast and impulse-stable high current capacitors is 260,000 uF. Only Schottky-diodes with extremely fast switching times are used. A highly constant and low-noise laboratory source serves as voltage reference. In an additional stage, high-precision operational amplifiers smooth the reference voltage once again and eliminate the remaining noise. The voltage regulators are built up as discrete and very fast MOSFET regulators. Their output voltage is constant and load-independent up to highest frequencies.
The EPS is therefore the ideal power supply for connected Audionet devices.
