The LF Audio WVC Quad Knob is a wireless controller for multi-zone audio systems, pairing two stacked concentric encoders side by side to give you four independent rings and four channel groups from a single control. It works alongside a WVC base station of any version, and its main 128 x 128 OLED display shows live volume, dB readout, amplifier temperature, supply voltage, battery level, and signal strength, while a dedicated secondary OLED keeps all four channel group levels visible at once.

Each knob includes a push button, and the aluminum housing gives the unit a solid feel for daily adjustment. The rechargeable battery charges over USB-C, the AuralSync wireless link is long-range and encrypted, and the knob supports automatic sleep with instant wake on press plus over-the-air firmware updates. Paired with a WVC-PRO base station, it also provides live spectrum and oscilloscope views.
