AES70 - CB Electronics to join the OCA Alliance

One of the prime reasons to visit the Los Angeles AES this year was to investigate ethernet control.

For the past 30 years CB have specialised in machine control using the Sony P2 protocol. For some time we have looked for a way forward using Ethernet but could not find a unified control protocol. There is AES67 but it does not define a method by which audio streams are discovered, connected or controlled. This year the AES published AES-70 specification based on the OCA (Open Control Architecture) protocol. AES-70 can be used to control audio streams and networked audio devices.

As a result of our discussions with the OCA Alliance, we felt is important to participate in defining the standard.  CB have started a project to develop applications using AES 70. Initially we are adding AES 70 to the TMC-1 - to enable control of networked inputs and/or outputs as the first stage in developing a networked monitoring system.

For the past 25 years interfacing old and new technologies has been a part of our business model. We will design  similar solutions to integrate AES 70 devices with existing and new technology.

PD-1v2 firmware - Now with 192 tracks

The latest PD-1v2 update available from the PD-1 web page allows a maximum of 128 tracks on the Main Output and 64 tracks on the Aux Output. The diagram below shows how to connect the PD-1 with two protools and run the PD-2-win/mac software on one of the protools/
