Description
Description
This LF Audio High Precision Amplifier is a Class D power amplifier built around PURIFI's EIGENTAKT output technology, delivering 230 watts per channel at 8 ohms, 450 watts at 4 ohms, and 510 watts at 2 ohms, all at no more than 1% THD+N. Its auto gain match reads the incoming signal and calibrates gain automatically across the 0.1 to 15.0 volt RCA range, using a digitally driven Class AB analog pre-amp circuit to hold distortion below 0.001% and avoid the gain drift that physical potentiometers develop over time.
A touch screen and multiple sensors put input voltage and amperage, output voltage, amperage, wattage, impedance, power factor, apparent power, real-time efficiency, and fast Fourier transform signal analysis in front of you, while the included WVC bass knob adds remote data telemetry and control. Optical input runs through ESS chips, and Bluetooth control is handled by the AuralSync app.
