THIS IS A PRE-ORDER FOR THE FOUNDERS EDITION, ONLY A HANDFUL WILL BE MADE! EXPECT DELIVERY BY END OF 2025

Every design aspect is subject to change as I continue refining the circuit, the functionality, and the design.

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
