WRAT

WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. A “closed ground-loop circuit” design is employed, in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers to immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current better manages speaker impedance fluctuations, which can negatively affect performance.
