Seamless Integration. Pure Signal. Effortless Amplification.

The Focal HILO V3 is a high/low level converter designed to make amplifier installation simple, clean, and fully compatible with OEM head units. Developed entirely by Focal, this third-generation converter ensures a high-quality audio signal while preserving all original vehicle controls.

By converting a stereo amplified signal into two low-level RCA outputs, the HILO V3 delivers a clean, interference-free signal path to your amplifier. Its advanced circuitry eliminates parasitic noise and isolates grounds for optimal clarity. The built-in impedance simulator replicates a speaker load to prevent head-unit muting ensuring perfect compatibility with modern systems.

Selectable DC and AC voltage detection further enhances versatility, allowing the HILO V3 to integrate seamlessly with virtually any factory audio configuration.
