London, UK – July 22, 2026 – In a significant development for the professional audio landscape, Kelsey Acoustics has officially announced that its KelseyVerse line of audio interfaces—specifically the KV-M22A and KV-M22D—has successfully achieved Milan certification. This milestone, confirmed by their formal inclusion in the Avnu Alliance Certified Product Registry, signals a new chapter for the company, aligning its legacy of high-performance infrastructure with the industry’s most rigorous standards for deterministic, interoperable networked audio.
For systems integrators, broadcast engineers, and live sound professionals, this certification serves as a guarantee of seamless connectivity within the Milan AVB (Audio Video Bridging) ecosystem, ensuring that these compact interfaces will perform reliably alongside certified hardware from any manufacturer.
Main Facts: The KelseyVerse Advantage
The KelseyVerse series represents a strategic pivot for Kelsey Acoustics, a company with over four decades of history in manufacturing high-end cabling and connectivity infrastructure. The two certified units, the KV-M22A and the KV-M22D, are designed to bridge the gap between legacy audio signals and the sophisticated, time-sensitive requirements of modern Milan networks.
- The KV-M22A: A specialized 2-in/2-out analog-to-Milan interface, facilitating the integration of traditional analog microphones, instruments, and line-level devices into an AVB-enabled digital infrastructure.
- The KV-M22D: A 4-in/4-out AES3-to-Milan interface, providing a streamlined path for digital console outputs, high-end outboard processors, and digital playback systems to interface directly with the network.
Central to the appeal of these devices is their adherence to the "plug-and-play" ethos of Milan. By achieving certification, these units confirm their ability to maintain clock synchronization, deterministic latency, and fault-tolerant operation—factors that are non-negotiable in critical broadcast and live event environments. Furthermore, both units leverage Power over Ethernet (PoE), adhering to IEEE 802.3af/at/bt standards, which significantly simplifies deployment by eliminating the need for localized power distribution.
A Chronology of Innovation: From Infrastructure to Networked Intelligence
To understand the significance of the KelseyVerse certification, one must look at the trajectory of Kelsey Acoustics over the past forty years.
The Foundation (1980s – 2010s)
For decades, Kelsey Acoustics built its reputation on the physical layer of the audio signal chain. As a provider of premium-grade cables, patch bays, and custom stage boxes, the company became synonymous with the "invisible" infrastructure that keeps concert tours and television studios running. Their expertise was rooted in signal integrity, noise rejection, and mechanical durability.
The Transition (2020 – 2025)
As the audio industry underwent a tectonic shift toward IP-based networking, Kelsey identified a gap in the market. While manufacturers were flooding the space with high-channel-count digital mixers and large-scale switches, there was a deficit in compact, reliable "edge" devices. In 2025, the development of the KelseyVerse range began, focusing on the needs of the integrator who requires a simple, bulletproof way to get two or four channels onto a network without the overhead of massive hardware.
The Certification Phase (2026)
The journey toward Avnu Alliance certification was characterized by rigorous laboratory testing. Milan certification is not merely a label; it requires exhaustive validation of the AVB stack to ensure that the device never causes "network jitter" or clock drift, even under heavy traffic. Following months of internal testing and independent validation by the Avnu Alliance, the KV-M22A and KV-M22D were officially ratified in July 2026, marking the formal arrival of Kelsey Acoustics as a player in the digital network domain.
Supporting Data: Why Milan Matters
The complexity of modern live sound and broadcast has outpaced the capabilities of traditional point-to-point analog cabling. When multiple devices from different manufacturers share a single network, the risk of "packet collisions" and synchronization errors increases exponentially.
Deterministic Performance
Milan is a protocol built on the IEEE 802.1 Audio Video Bridging standards. Unlike other protocols that rely on "best-effort" delivery, Milan is deterministic. It reserves bandwidth on the network, ensuring that audio packets arrive with microsecond precision. The KelseyVerse interfaces, now certified, have proven their ability to adhere to this timing, which is essential for multi-speaker arrays and complex surround sound setups.
Power over Ethernet (PoE) Efficiency
The inclusion of IEEE 802.3bt compatibility allows the KV-M22A and KV-M22D to operate in environments where traditional AC power may be difficult to access. This is particularly beneficial in:
- Distributed Sound Systems: Placing interfaces near stage boxes or in remote rafters for ambient microphones.
- Studio Installations: Reducing cable clutter behind workstations.
- Rack Integration: The optional 1U rack adapter kits allow for single or dual-unit mounting, providing a professional finish for permanent installs.
Official Responses: A Vision for the Future
Tony Torlini, General Manager at Kelsey Acoustics, emphasizes that this certification is more than a marketing achievement—it is a continuation of the company’s commitment to the professional user.
"Achieving Milan certification is a significant milestone for KelseyVerse and for Kelsey more broadly," says Torlini. "It gives integrators and engineers confidence that the KV-M22A and KV-M22D will work seamlessly with any other certified device on the network, regardless of brand. This is the standard our customers expect from Kelsey after 40-plus years of building infrastructure for live sound, broadcast, and studio environments."
The sentiment within the industry has been largely positive. By providing an interface that prioritizes reliability over feature bloat, Kelsey is addressing a specific pain point for engineers: the need for a stable, high-fidelity entry point into the network.
Implications: The Shift Toward Interoperable Ecosystems
The certification of the KV-M22A and KV-M22D has immediate implications for the professional audio market, particularly regarding how systems are designed and maintained.
The End of Vendor Lock-in
For years, manufacturers pushed proprietary network protocols that required specialized hardware from a single brand. Milan represents a departure from this siloed approach. With KelseyVerse devices now part of the registry, an integrator can use a Milan-certified console from Brand X, speakers from Brand Y, and the KelseyVerse interface from Brand Z, all while knowing that the underlying network will function as a unified entity.
Simplified Troubleshooting
One of the greatest fears for any live sound engineer is a "network meltdown" during a show. Because Milan requires devices to report their capabilities and performance status in a standardized way, the inclusion of KelseyVerse units makes it easier for network management software to identify and isolate issues. If a signal chain fails, the technician can be confident that the fault lies elsewhere, rather than in an incompatible interface.
The Future of Infrastructure
Kelsey Acoustics has effectively signaled that they are not abandoning their roots; rather, they are digitizing them. As we look toward the remainder of 2026 and into 2027, it is highly likely that we will see an expansion of the KelseyVerse line. The current success of the M22 series suggests a blueprint for future products—compact, robust, and impeccably compliant with the highest standards of the industry.
Conclusion
The path to Milan certification is long and demanding, reserved for companies that prioritize technical accuracy over speed to market. For Kelsey Acoustics, this achievement is a validation of their pivot toward the future of IP-based audio. By providing a bridge between the physical and the digital, the KV-M22A and KV-M22D ensure that the next generation of sound systems will be more reliable, more flexible, and more interoperable than ever before.
For those looking to integrate these interfaces into their current workflows, detailed documentation, specification sheets, and the comprehensive KelseyVerse & Milan Manager user guide are now available via the official Kelsey Acoustics website. As the industry continues to move toward a more integrated, networked future, Kelsey Acoustics has firmly established its position as a provider of the essential infrastructure that makes it all possible.
