Be one of the first in the world to own an LF Audio Amplifier! THIS IS A PRE-ORDER FOR THE FOUNDERS EDITION - EXPECT DELIVERY in 2026 Every design aspect is subject to change as I continue refining the circuit, the functionality, and the design. Unique Features Gorgeous touch screen Comes with a WVC bass knob for remote data telemetry and control Multiple sensors to monitor and display data for: input voltage and amperage output voltage, amperage, wattage, impedance, power factor, apparent power real-time efficiency real-time signal-analysis (just like the WVC-PRO) with fast fourier transform of the signal Auto gain match (1-15v RCA input) Intelligently detects signal level and auto calibrates gain level Uses high quality Class AB analog pre-amp circuit driven digitally to achieve lowest THD and avoid gain walking (physical potentiometers can drift / wear out over time) Optical input using ESS chips Equalizer views, animations, and more Bluetooth connection / control via AuralSync™ app Specs Power RMS ≤ 1% THD+N - @ 8 Ohms 230 Watts per channel - @ 4 Ohms 450 Watts per channel - @ 2 Ohms 510 Watts per channel Inputs 2 x RCA1 x Remote In1 x Optical In Input sensitivity RCA 0.1 - 15.0 Volts Input impedance RCA 12 kOhms Outputs 1/2/4 Speaker outputs (depending on model) Frequency response 10 Hz - 60 kHz Signal-to-noise ratio analog input > 125 dB (A-weighted) Distortion (THD) < 0.001 % Damping factor > 10,000 Operating voltage 9 - 18 Volts Output technology PURIFI's "EIGENTAKT" Class D Show more
