Developed specifically for professional use in the fields of event technology, studio, TV, and broadcast, the Palmer RIVER naab is a two-channel, DI box designed to eliminate ground-loop hum and buzz when connecting a playback device (e.g. laptop, tablet, CD player) to a mixing console or PA system. It can also be used to convert unbalanced signals into balanced signals for sending audio over long cable runs without interfering noise. To eliminate the need for adapter cables, naab is equipped with a variety of inputs including two 1/4" jacks (which can be balanced or unbalanced), two RCA unbalanced connectors, and a 3.5mm TRS unbalanced stereo connector. The balanced line outputs are on two 3-pin XLR male connectors. With switchable mono/stereo mode, the box can pass either a stereo signal or two independent mono signals without causing any sound alteration or noise.
RIVER naab features a simple and reliable passive design that requires no battery. It utilizes galvanic-isolation technology via its transformers to preserve the sound quality of your audio channels. Use the ground-lift switches to disconnect the ground connections from the inputs and outputs and further eliminate hum loops.
Engineered in Germany and built to last, the unit is virtually indestructible thanks to its rugged, aluminum-and-steel casing and reinforced connectors.
