RME presents the LNI-2 DC, a spectacular active DC filter, compact and portable, milled from a solid block of aluminium. The LNI-2 DC provides isolation, regulation and filtering of output signals from any 12 volt DC power source, enabling a remarkable improvement in DC voltage stability while providing an ultra-clean 12V power source. This results in an enhanced audio signal and sound quality avoiding humming, buzzing and other noises that can be caused by power supplies or dirty mains power.
The LNI-2 DC is based on two key features: galvanic isolation and RME's exclusive ?Filter. Galvanic isolation is an advanced technique to prevent any noise, from hum over high frequency noise to leakage currents from reaching the filtered DC output. Without galvanic isolation parts of these noises will creep over into the filtered signal. Galvanic isolation makes it possible to not only filter the positive DC path, but also separates ground (aka minus) between input and output.
The LNI-2 DC handles power sources from 9-18V DC (input) and provides a fixed, perfect voltage of 12.0 V at 2 A at the lockable output socket. This is ensured by the µFilter's integrated sensor technology, which checks and compares the output voltage directly at the DC connector of the supplied 4-wire cable, thus completely avoiding any load-dependent voltage drops. Two DC Sensor connection cable with lockable & non-lockable DC plug 2.1 x 5.5 mm, (1 m) are included.
