Quick access via WiFi with QR code scan

One of the most forward-thinking features of the Audio Codec Servers is the option to quickly connect with the management UI using the wifi of your mobile devices. This is in addition to the regular network access. Things are sped up even further by using a QR code scan to access the wifi.

You can say goodbye to outdated front panel controls and enjoy an operation method that ensures you can use all of your audio codec’s functions without a computer and without any compromises. The same UI you have become used to with browser access can be used with your mobile devices.

Grow with expansion packages

All Audio Codec Servers can be expanded to fit multiple use cases at once. Turn an OTT machine into a SIP hub, add transcoding to DVB, change a Loudness controller into a podcast processor – it’s like a matrix of possibility.

The PIPE Concept makes audio stream and call configuration as simple as never before. A row of elements represents each aspect of the connection and coniguration is as easy as using drag-and-drop, while detailed configurations of the elements are available with a single click. Even complex connections can be set up in a few seconds and a minimum of clicks.

It is the simplest and most powerful way to configure your audio connections. Configuring and monitoring your audio I/O was never easier.

Note that a single PIPE can handle a mono, stereo or multichannel signal coming from one input and sent to one output. You do not pay for channels used, but separate connections made!
