ESI launches Planet 22c Audio Interface


ESI has introduced the Planet 22c, a compact interface box that provides 2 analog input and 2 analog output channels at reference audio quality in a Dante IP audio network.


Dante is a standard for routing audio over IP, making it possible to send multiple channels of high-end audio over standard Ethernet cables.


The Planet 22c is equipped with 24-bit / 96kHz analog-to-digital and digital-to-analog converters, supporting balanced line audio signals with home (-10dBV) and professional (+4dBu) signal levels. This makes planet 22c ideal to interface any analog equipment such as a traditional mixer, studio monitors or PA speakers, synthesizers or other electronic instruments with the Dante world.


In addition, it can be powered directly from the Ethernet cable as a PoE (Power over Ethernet) device, besides  via the included 12V DC power adapter. This is perfect when using it in a remote location. It can also be integrated into a modern music studio when using the optional Dante Virtual Soundcard (DVS) software for PC or Mac.
