Viamux DAB in the Cloud 
The fully-managed 'DAB as a service' solution
The Viamux cloud solution is a breakthrough for small-scale DAB in that it significantly reduces the capital investment required to own and operate a small-scale multiplex. DAB in the Cloud takes a radio station's existing web stream and encodes the audio in the cloud. Multiple DAB/DAB+ encoded streams are then 'blended' into a single multiplexed stream - which is sent over the internet to the transmission site(s) for broadcast.  The Optimux software is accessible from a desktop, tablet or phone. It provides a user-friendly dashboard interface to manage every aspect of the multiplex  

Optimux 
The complete small-scale DAB multiplex management solution
Optimux is a powerful and easy to use multiplex management solution. Fully ODR-compatible, the user-friendly dashboard allows administrators to add, remove and configure stations on the multiplex. Optimux continually monitors the multiplex with SMS/email alerts enabled and full performance reporting available to stations.  The Finance module  includes invoicing and automated collection of carriage fees by Direct Debit. The Monitor module enables the multiplex operator and service providers to listen to the audio feed of their DAB broadcast from any individual transmitter in the network.
