With this in mind, TSL’s extensive range of audio products includes support for Dante, AES67 and ST 2110, among other technologies. CONNECT AND CONTROL But while the transport aspect of standards for audio networking may have reached maturity now, the same can’t be said of network control. “With a standard such as AES67,” says Carpenter, “the focus was on the transport side – it doesn’t go into great detail about how to discover and connect streams between different equipment.” He adds that the standard suggests the Session Announcement Protocol (SAP) as a method to simplify connection of streams, but this wasn't universally adopted. Broadcast production services company NEP Group is an enduring customer of TSL Products, using the MPA1 MIX MADI-V units for live broadcast monitoring on a long-term basis. NEP has also invested in TSL’s PAM2-IP units, which enable the monitoring of ST 2022-6 and ST 2110 IP sources, as well as offering compliance with Dante Domain Manager – with primary and secondary Dante ports for connection into its networks – and SDI, AES and analogue connectivity. Putting individual AoIP technologies aside, NEP's Naugle agrees that “control and integration are still challenging areas. Lots of the issues we encounter are about interfacing between equipment”. MAKING IP ADOPTION EASY With this observation in mind, TSL Products has developed the answer, following in the footsteps of its agile monitoring solution, SAM-Q-SDI. This

allowed users to control and visualise their (non-IP) audio content based on application, environment or personal preference. Now, with the forthcoming SAM-Q-NET 1RU unit, TSL will bring the same monitoring and control adaptability to IP audio. With shipping expected to start in early 2022, Carpenter says: “The 1 GigE connectivity will provide great overall cost-benefit, and allow the support of 2110-30 and other IP technologies. There will also be great flexibility in terms of the method of control, and people will be able to integrate their own control system, either by using NMOS [Networked Media Open Specifications] or our RESTful API.” SAM-Q-NET is the fruition of TSL’s emphasis on delivering the utmost flexibility for customers adopting IP audio. “We focus on keeping up with the latest technologies and being as agnostic as possible. That will remain central to our approach in the future.”
