How to use


To use the NetMixer a network is required connecting all clients to the server, best performance is achieved using udp over a single subnet.

Audio cabling is required linking the server audio output to the client input.


  • Set Network up
  • Assign NetMixer ID
  • Start Audio
  • Adjust input levels as required


  • Set Network up
  • Set NetMixer ID
  • Set client ID (matches server audio output)
  • Check input monitor


  • More than 1 NetMixer may be run using different NetMixer IDs
  • No audio is transmitted over the network (due to performance requirements)

Reasons for V2

Version 2 was developed due to consistently encountered hardware limitations when working with more than 8 audio ins or out.

As a consequence version 2 removes support for more than 8 ins or outs and is much leaner code. It does however add support for multiple NetMixers within a subnet which was unsupported in v1.
