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.

It can be powered not only via the included 12V DC power adapter but also directly from the Ethernet cable as a PoE (Power over Ethernet) device. 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.

  1. i bought a midi thru box from Esi once, turned out they were the only brand of these boxes not handling any System exclusive data.
