Professional 2 Channel Solution

The fernStudio Light combines a compact design ( 19” and 1 RU) with great versatility at an affordable price. This makes it the perfect choice for many RTP and SIP transmission applications. If the regular fernStudio has more channels than you need, the fernStudio Light is the alternative for you. It still supports all professional and industry standards like encoding with Opus, AAC, xHE AAC, mp3, FLAC, Vorbis but also supports new developments like AES67 I/O and all of this at absolute reliability. It also has power for all auxiliary codec features, like audio recording and analyzation, automatization, VPN and more.

Broad Codec and Protocol Support

All aixtream products represent the cutting edge of contemporary audio transmission and recording technology. All modern formats and protocols are supported and new developments are quickly adapted into the ferncast reportoire. This shows itself in the wide range of available codec algorithms, including Opus, AAC, xHE AAC, mp3, Vorbis and more, and also in all the supported transport and streaming protocols. RTP and SIP are supported studio and for classical broadcasting applications, just like HLS, RTMP and IceCast for OTT streaming. DVB transmission too is available, and with our focus on cutting edge technology input and output via AES67 is of course also possible.

Highly Customizable Controls

Perhaps the biggest advantage of the aixtream software for the customer is its exceptional customizability. This is especially important for the large number of diverse applications that each of our products supports. With a customizable Dashboard for instant control and monitoring, as well as as many search and filter functions for the fastest possible navigation, the GUI can do whatever you need it to. And should something, despite expectations, not fit your use case, we are happy to make adjustments for you as necessary.
