In order to feed your amplifiers with an appropriate and qualitative audio signal, keeping your original head-units and the associated OEM controls, you can choose the converter HILO.V3. HILO.V3 converts a stereo amplified signal in two low-level line outputs, eliminates parasitic interferences and generates separated grounds. You can now use an amplifier very simply, without any interference. It is now very easy to create a quality hi-fi install in your car. The selectable DC and AC voltages detection makes the HILO compatible with any original manufacturer head units. Entirely developed by Focal, HILO is available under generation 3 with an impedance simulator that creates a speaker simulation network to avoid head-unit muting.
