Palmer RIVER naab
The Palmer RIVER Naab is a passive 2-channel direct-in box designed to easily connect a laptop, audio player, tablet, or any other multimedia device to a mixing console or professional sound system.
Thanks to its galvanic isolation transformers, it effectively eliminates ground loops and any noise that may occur when connecting multimedia devices to an audio system.
The RIVER Naab features highly versatile connectivity with 2 6.35 mm jack inputs, 2 RCA inputs, and 1 3.5 mm stereo mini-jack input. The two balanced XLR outputs then allow the signal to be sent to a mixing console or sound reinforcement system, even over long distances.
A switch allows you to toggle between stereo and mono modes. In mono mode, the summed signal is available simultaneously on both XLR outputs, which also allows the Naab to be used as a signal distribution solution.
The Ground Lift system helps eliminate grounding issues, while the impedance matching provided by the transformers ensures a clean and balanced signal.
Fully passive, the Palmer RIVER Naab requires no power supply. Its rugged metal housing makes it particularly well-suited for live performances, audiovisual installations, conferences, DJ sets, and professional applications.
