Passion City Church Builds Future-Proof Live Audio Transport Solution on Artel Quarra PTP Ethernet Switch
Artel Video Systems, a world-class provider of innovative, real-time multimedia delivery solutions, today announced that Passion City Church is using two Artel Quarra 1G PTP Ethernet switches to support IP-based handling of audio signals being transported between its two main Atlanta church locations — “515” and Cumberland — and a third site in Trilith, Georgia, to support worship services, events, and other productions.
“The high-performance feature set of Quarra and its level of timing accuracy allows us to leverage the power and flexibility of IP in the most reliable way,” said Stephen Bailey, Lead Audio Engineer at Passion City Church. “Having this infrastructure in place allows us to be ‘living in the future,’ capable of exchanging full-resolution audio to wherever there’s an internet connection while being ST 2110-ready at the push of a button.”
Passion City Church uses a dark fiber connection between the three locations to support bidirectional RAVENNA audio transport. This approach allows the church to implement audio over IP (AoIP) transport now while maintaining the flexibility and scalability to move toward SMPTE ST 2110-based media transport in the future.
Fully compatible with RAVENNA, Artel’s Quarra switch serves as the networking element that allows Passion City Church to move a large volume of audio signals between multiple sites with ease and reliability. With exceptionally accurate IEEE 1588v2 timing, the switch also provides the accurate PTP synchronization essential for audio over IP applications. During concurrent live services across all three sites, Passion City Church leverages this accuracy to allow three separate bands at different sites to perform together live, all playing the same song at the same time.
“Few houses of worship embrace the possibilities of AoIP, and it’s exciting to see Passion City Church approach this recent audio transport challenge with an eye toward the future,” said Paul Seiden, Director of Sales at Artel. “Designed for demanding applications including pro AV and broadcast, Quarra is a great choice for any worship facility with plans for IP migration. It ensures interoperability along this journey and boasts the capabilities needed to maintain the quality of real-time audio streams.”

Artel’s Quarra Switches Support SLG’s Install of IP-Native Lawo Diamond Radio Consoles for CH Media Group
Artel Video Systems, a world-class provider of innovative, real-time multimedia delivery solutions, today announced that Swiss systems integrator SLG has installed Artel Quarra PTP Ethernet switches to support seven Lawo IP-native diamond radio consoles installed in control and production rooms at CH Media Group. The Quarra switches facilitate an audio-over-IP workflow for this industry-first deployment of the brand-new Lawo consoles.8
“This was a large-scale implementation of media-over-IP, and we chose to work with Artel because we trust both the company and its Quarra switches,” said Francesco Mattuzzi, Project Manager at SLG Broadcast. “The install was straightforward, as we anticipated, and our customer was very pleased with how smoothly we were able to complete the project.”
“We knew going into the project that Quarra has enabled many successful migrations to IP,” added Steve Handke, Head of Technology TV & Radio at CH Media. “Given this track record, we were confident following SLG’s recommendation of the Quarra along with our new Lawo consoles.”
The IP-native diamond radio console is based on the open AES67/RAVENNA audio-over-IP network standards and complies with SMPTE ST 2110-30/-31 and ST2022-7 standards. Artel’s Quarra PTP Ethernet switch accommodates all of these standards, provides leading-edge PTP switch technology, and supports the CH Media Group’s implementation of the Lawo consoles by providing the breadth of essential features and functionality.
“SLG is a leading systems integrator specializing in IP migrations, and we’re proud to be trusted by the company — and innovative end users including CH Media Group — for these types of mission-critical implementations,” said Paul Seiden, Director of Sales at Artel.

PTP Boundary Clock Testing of Artel’s Quarra switch
Video, audio, and metadata signals have always depended on precise synchronization along the entire delivery chain. As the industry transitions to IP networks for all aspects of the signal processing path, accurate timing becomes more difficult, due to the fundamentally asynchronous, non-deterministic nature of packet-based networks.
As we know by now the solution is Precision Time Protocol (PTP) as it can synchronize device clocks to within nanoseconds across a large network with many hundreds of nodes.
The Quarra range of boundary and transparent clock switches are PTP capable, offering an excellent solution set for reducing jitter in a real-time media IP network. As the broadcast industry continues to migrate toward all-IP networks, providing reliable solutions to manage IP-based workflows becomes paramount to maintaining efficiencies and ensuring the delivery of mission-critical multimedia streams.

Time Travels – A Closer Look at PTP
IP video and audio technology is moving rapidly into all facets of media production, and PTP is the essential technology to provide absolute synchronization of the timing relationships of all devices. This is a requirement in delivering mission-critical media signals in IP- and fiber-based ecosystems.
PTP specifies a methodology for synchronizing devices to a single, shared clock across packet-based networks, including Ethernet switches and IP routers. This standard, which was originally developed for laboratory and industrial installations, is now fundamental for IP video/audio signal transport using SMPTE ST 2110 and IP audio signals using AES67, among other media applications. PTP creates a common time base for multiple video cameras and is used to synchronize video and audio devices to a uniform clock or timecode. When used properly, PTP can synchronize device clocks to within nanoseconds of each other across a large network with hundreds of nodes.
“Time Travels — A Closer Look at PTP” examines the key elements and considerations of PTP deployments including PTP synchronization, master clock selection, transparent and boundary clock functions, PTP domain and profile configuration, and other network considerations.

It’s About (Precision) Time
With the emergence of IP in sport broadcasts, the need to maintain and improve synchronization among end points, devices, and processes across a broadcasters’ network is critical. This is of most importance in live sports broadcast productions. Precision Timing Protocol (PTP) is the backbone of an IP live sports broadcast as it enables the integration of audio and video in the time and phase domain, allowing for effective media processing. By leveraging the networking flexibilities of IP and combining it with a sound implementation of PTP, sports broadcasters could cost effectively introduce novel workflows, resulting in an improved and unique viewer experience. In addition, it allows for leveraging the efficiencies of media essence integration, remote production, and the ubiquity of IP networks to deliver live content of second and third-tier sports production.
PTP is the foundation upon which sports broadcasters can build automatic processes, creative workflows, and innovation. In this white paper, we will provide an overview of the importance of PTP, using the SMPTE Epoch for synchronization; benefits, system components, and applications for media.
