Calrec and Grass Valley unlock exceptional choice and flexibility for broadcasters with ImPulseV and AMPP integration

The companies are building a strong broadcast audio technology roadmap to remove barriers to software-defined production. Global broadcasters will benefit from unprecedented flexibility with zero compromise on quality.

NAB Show 2026, Las Vegas, April 18, 2026 - Calrec (Booth:C6907) and Grass Valley (Booth: C2408) are today announcing a long-term broadcast audio technology partnership at NAB Show 2026. The companies are combining their industry expertise to deliver a software-defined production environment that will see Calrec's ImPulseV virtual DSP software integrated with Grass Valley's AMPP cloud-native live production platform. The deployment will provide broadcasters with a unified environment for managing live broadcasts.

Coupling Grass Valley's leadership in video production with Calrec's trusted broadcast audio expertise, ImPulseV, strengthens audio workflows within Grass Valley's AMPP market leading Ecosystem. The partnership provides all the benefits of close integration and orchestration with proven applications from renowned broadcast partners on a single platform. Calrec's pathway into AMPP OS will start with AMPP Control integration and evolve towards a fully native ImPulseV application running on AMPP.

The collaboration strengthens AMPP's tier 1 audio capabilities alongside its tier 1 video production strengths, creating a single platform for high-end live productions. The partnership reinforces the industry's direction for software defined production, open standards and collaboration as the drivers of innovation. As hybrid workflows continue to develop, the partnership gives broadcasters the confidence to define and scale their own infrastructure requirements, and to fully utilise their resources.

Sid Stanley, Managing Director at Calrec says, "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."

Sid continues: "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.

"This is not just an important announcement for today, but a meaningful step towards the future. Both Grass Valley and Calrec are deeply committed to continuous innovation and investment - because in a world moving this fast, standing still is not an option."

Adam Marshall, Chief Product Officer at Grass Valley, says, "With the integration of Calrec's ImPulseV into AMPP, we are extending the power of software-defined production with tier-one audio workflows. Media organizations 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."

Freedom without compromise

As media organisations increasingly look to consolidate their technology stacks and reduce operational complexity, audio has remained one of the most challenging workflows to virtualise - without compromising quality, latency or the operator experience.

The cohesive Calrec ImPulseV and Grass Valley AMPP integration is designed to meet these challenges, delivering:

• Common orchestration
• Shared control
• Scalable infrastructure
• Cloud and on-prem flexibility
• Elastic resources aligned to live production demands
• A modern, software defined architecture designed for long-term flexibility

"We are giving broadcasters maximum flexibility in how and where they deploy their audio production; without forcing them to choose between functionality, quality and control," adds Stanley.

Virtualisation with purpose - zero limitations

Calrec's ImPulseV creates flexible workflows across COTS hardware, public and private cloud, existing processing hardware and distributed resources, contributing to an efficient, flexible hybrid production environment. ImPulseV is part of Calrec's Ecosystem, powered by True Control 2.0, which unifies the company's high-end control surfaces with remote production capabilities. Broadcasters can use True Control 2.0 to manage up to five Calrec consoles or processing cores simultaneously.

By integrating ImPulseV with AMPP, broadcasters' flexibility to manage their assets is further expanded. One control surface can adapt - without loss of quality - to local, cloud and remote productions.

Both ImpulseV and AMPP provide OpEx based deployment models, enabling broadcasters to expand event coverage. The integration delivers audio capabilities that scale, without compromising the operator experience.

Calrec is exhibiting at NAB Show on Booth C6907, and Grass Valley is on Booth C2408. The integrated ImPulseV and AMPP workflow will be demonstrated on the Grass Valley booth (C2408).
