GLOBAL: A landmark collaboration that reflects the accelerating shift toward virtualised and cloud-native workflows – Calrec and Grass Valley have announced a long-term broadcast audio technology partnership that brings Calrec’s ImPulseV virtual DSP engine into Grass Valley’s AMPP cloud-native live production platform.

The integration establishes a unified, software-defined production environment where high-end audio and video workflows coexist seamlessly within a single ecosystem. By combining Grass Valley’s leadership in video production with Calrec’s deep-rooted expertise in broadcast audio, the partnership strengthens AMPP’s capabilities with tier-one audio processing—delivering a comprehensive platform tailored for modern live production demands.

At the heart of the collaboration is ImPulseV, Calrec’s virtual DSP solution, which will initially integrate with AMPP Control before evolving into a fully native application within the AMPP OS. This progression reflects a broader industry movement toward open, scalable, and software-defined infrastructures that allow broadcasters to build, adapt, and scale operations with unprecedented flexibility.

Sid Stanley, Managing Director at Calrec, emphasised the strategic significance of the partnership. “We are delighted to be partnering with Grass Valley, an organisation that shares our belief that innovation, people, and technology define the future of our industry. In today’s fast-moving production landscape, strong solutions and trusted collaborations are more critical than ever.

“Our virtual ImPulseV technology, combined with the Grass Valley’s AMPP Ecosystem, creates a powerful proposition, uniting best-in-class solutions to give broadcasters the freedom to build, scale, and adapt without compromise. This marks the next evolution of Calrec’s strategy, empowering our customers with true choice, flexibility, and control in a software-defined world.”

As hybrid production models continue to gain traction, the integration directly addresses one of the industry’s most persistent challenges: virtualising audio workflows without sacrificing quality, latency, or operator familiarity. By delivering tightly integrated orchestration, shared control, and scalable infrastructure across cloud, on-premise and hybrid environments, the solution enables broadcasters to align resources dynamically with production demands.

Stanley continued, “As our industry transforms, the need for agile, scalable, future-ready solutions has never been greater. Together, Calrec and Grass Valley are setting a new standard, combining cloud, virtualisation, and multi-vendor integration into one seamless ecosystem for next generation production.

“The introduction of ImPulseV into this ecosystem is a key milestone, enabling customers to deploy everything from micro-control rooms to global production environments with speed and precision – shaping infrastructure around their needs, not the other way around.”

Adam Marshall, Chief Product Officer at Grass Valley, highlighted the impact on high-value productions. “With the integration of Calrec’s ImPulseV into AMPP, we are extending the power of software-defined production with tier-one audio workflows. Media organisations can now deploy premium audio capabilities in a fully software-defined environment while maintaining the quality, responsiveness, and familiar operator control expected for high-value live production. Whether on-prem, in the cloud, or across hybrid environments, it all operates within a single, unified platform.”

Built around Calrec’s True Control 2.0 framework, ImPulseV enables flexible workflows across COTS hardware, public and private cloud, existing processing systems and distributed resources. Operators can manage up to five Calrec consoles or processing cores simultaneously from a single control surface, which can dynamically adapt across local, remote and cloud-based production environments without compromising performance.

The integration also aligns with the industry’s growing shift toward OpEx-based deployment models, allowing broadcasters to scale coverage more efficiently while maintaining consistent operational standards.
