Audio Review: Barix Technology Instreamer 100, Exstreamer 100, and Annuncicom 100

Trio of audio-over-IP devices sport practical design and easy setup.

I was able to successfully stream audio from both the Instreamer 100 and Annuncicom 100 and receive it with the Exstreamer 100. The quality of the audio is contingent on the settings. With high-quality audio, there is latency, but in most of the applications for which these devices would be used, latency doesn't present a serious problem. These devices are not intended to be used as multichannel snakes for live sound or some similar application. In light of the considerable ease with which I was able to set up and configure these devices, it's obvious to me that even a system using a great number of these devices would be simple to set up and run. It's straightforward and documented clearly by .pdf files available from the Barix website. One minor quibble: It would be nice to have all the documentation printed and included with the units.

The Exstreamer 100 and Annuncicom 100 are individual units belonging to larger families of devices from Barix, but the Instreamer 100 is the only device in its class. I can say that if the other devices in these series are as well-planned, well-made, and simple to use, Barix is poised for great success in the future. These devices are not sexy in the traditional sense of the word, but they are highly useful and easily configured for virtually any application imaginable. I definitely recommend taking a look at them.
