Hifonics HF-SC4-ISO

HiFonics signal converters impress with their absolutely brilliant sound qualities. This result is no coincidence, as the developers placed the utmost importance on excellent technical specifications right from the design stage. And they certainly have a lot to show for it: sensationally high signal-to-noise ratios of 115–121 dB combined with very low total harmonic distortion of 0.00*1% impressively demonstrate that these converters are true highlights. They are designed for connection to conventional car radios that deliver up to 50 W/RMS per channel at 2 ohms.

Another special feature of these multi-channel converters is their summing function. This circuit is essential for many new vehicles when the music signal cannot be tapped "in one piece," but the frequency ranges for the factory-installed speakers have been electrically separated. A conventional converter would be completely useless here. With the HF-SC converters, however, the split output signals of the factory system can easily be recombined by activating the "MIXED" function via the switch. The sophisticated electronics then generate a full-range signal at the outputs, which can be used to optimally drive external DSPs or amplifiers.

Thanks to EPS®, the converters can also be connected without any problems to factory radios that have a so-called load detection circuit. As an additional interference suppression feature, a "floating ground" can be activated via a jumper.

Thanks to the convenient ISO connectors, there is no need to cut the cables behind the car radio as would otherwise be necessary. Simply pull the plug out of the radio, adapt the wiring harness of the ISO versions, and you're done. Anyone whose car radio does not have an ISO connection can even use the optional MPK T-cable adapters to adapt over 100 additional vehicles and obtain a complete plug-and-play system.
