Hifonics HF-SC4 - 4-channel "High/Low Level" converter

HF-SC4

The signal converters from HiFonics   impress with their absolutely brilliant sound characteristics. This result is no coincidence, as the developers placed great emphasis on outstanding technical data right from the design stage. And these are truly impressive: sensationally high signal-to-noise ratios of 115-121 dB combined with very low distortion factors of 0.001% impressively demonstrate that these converters are real highlights. They are designed for connection to conventional car radios that deliver up to 50 watts RMS per channel at 2 ohms.

Another special feature of the multi-channel converters is their summing function. This circuit is a must for many new vehicles if 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, on the other hand, the split output signals of the factory system can be easily recombined by activating the "MIXED" function via a switch. The sophisticated electronics then generate a full-range signal at the outputs, which can be used to optimally control external DSPs or amplifiers.

Thanks to EPS, the converters can also be easily connected to factory radios that have a so-called load detection circuit. As a further feature for interference suppression, "floating ground" can be activated via a jumper.
