In the world of modern car audio, integrating into the OEM sound system is one of the most prominent challenges that we face in nearly any installation. Our ResoNix EZ M-MO150 Interface seamlessly converts the MOST150 signal that is used in select Mercedes sound systems, typically ones that feature the Burmester OEM sound system trim, into a usable digital output. It features an S/PDIF toslink output AND coaxial output to allow you to have a clean digital signal that features none of the OEM processing for an easy, straightforward, and clean sounding car audio system design and installation. This is much preferred over having to do high-level signal integration, which will have you battling distortion, bass roll-off, equalization, crossovers, all pass filters, upmixers, limiters, variable volume equalization, and more. The ResoNix EZ Interfaces retain all OEM features, including backup sensors, door chimes, navigation prompts, Bluetooth calls, and more, unless specific otherwise. Please note that SOS systems are usually separate from the audio system and are left alone.
