With the Palmer RIVER lahn you can integrate analogue audio devices into a Dante® network: the lahn is an end-of-network interface that can be used to feed two analogue microphone or line signals into a Dante® network. Thanks to the bidirectional functionality, Dante® signals can also be converted into high-quality analogue audio signals to feed them into mixers, amplifiers, or loudspeakers.
With four-stage gain control and 48 V phantom power per channel, the RIVER lahn offers precise control and flexibility for various application scenarios. The lockable XLR audio connectors and the Neutrik® etherCON® network socket ensure secure connections, while the simple configuration on the front and the user lock on the control panel ensure user-friendly handling.
Each channel is equipped with a signal display that shows you the status of your audio transmission at all times. In addition to the power supply unit included in the packaging content, PoE (Power over Ethernet) can also be used for the power supply, which offers additional flexibility with regard to installation. Developed in Germany, the RIVER lahn is compatible with Dante® Domain Manager and AES 67. The solid aluminium and steel housing guarantees durability and robustness, making it ideal for use in demanding environments.
Experience the seamless integration of analogue and digital audio technology with the Palmer® RIVER lahn and benefit from first-class audio quality and ease of use.
