- Isolation, regulation and filtering of output signals from any 12 volt DC power source
- Significantly reduces the leakage current usually associated with switching power supplies
- Two status LED at the top of the unit signal existing input and output voltage and overload
The RME LNI-2 DC is an active DC filter in a compact and portable design. 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.
GALVANIC ISOLATION
The LNI-2 DC is based on two key features: galvanic isolation and RME's exclusive μFilter. The galvanic isolation significantly reduces the leakage current usually associated with switching power supplies. At the same time the capacitive coupling between input and output is reduced from typically 1 nF (nano-farad) to less than 35 pF (pico-farad) to prevent noise from the leakage current.
RME'S MICRON FILTER
The μFilter (micron filter) of the LNI-2 DC consists of a discrete Ultra Low Noise linear regulator with extremely low noise output of only a few μV (micro-volt), soft start, thermal overload, short circuit protection and sensor technology.
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 status LED at the top of the unit signal existing input and output voltage and overload. As further special feature the ground of the DC output can optionally be connected to PE, ground or other devices ground via a ground terminal screw to solve ground cabling issues.
Another unique feature is the 17-page manual, which shows the technical data in detail using many measured values illustrated with measurement diagrams. It also contains background information on linear and switching power supplies.
