Calrec is showing its new Impulse core audio processing platform at IBC2018. The Impulse core is a powerful audio processing and routing engine with AES67 and SMPTE 2110 connectivity, and is compatible with existing Apollo and Artemis control surfaces.

Impulse provides 3D immersive path widths and panning for NGA (next generation audio) applications, 5.1, 5.1.2, 5.1.4, 7.1, 7.1.2 and 7.1.4 input channels, busses, monitoring and metering are available. Height and 3D pan controls are provided, and paths of all widths can co-exist within a mix and be routed to/from each other with flexible panning and downmixing built in.

Impulse has an integral AoIP router, which fully supports NMOS discovery and connection management, as well as mDNS/Ravenna discovery. Up to four router cards can be fitted, each with a 4096 x 4096 audio routing matrix, and can operate at 1 or 10Gbps. Two 5U Impulse cores can be combined to provide full redundancy and can be physically remote from each other for disaster recovery.

“Impulse is a very robust and scalable DSP platform that illustrates a clear direction for Calrec’s future development, giving our customers a fully defined upgrade path as they transfer to IP infrastructures,” said Dave Letson, Calrec’s VP of Sales. “In addition, future scalable expansion will allow up to threeDSP mix engines and control systems to run independently on a single core at the same time, providing the ability to use multiple large-format mixers simultaneously in an extremely cost-effective and compact footprint.”

“The signal processing capacity of the Impulse core is unlike anything else available and is the most powerful DSP engine on the planet,” continued Letson. “It utilises the next generation of Calrec’s award-winning Bluefin DSP technology – Blu3fin – with five different user-upgradable DSP packs, all of which will be available from launch and range from 256 input channels in the XS Pack to 1,122ch in the XL Pack. In fact, Impulse provides more than 400 independent busses; 192 x mains/groups, 48 x auxes, 96 x tracks, with 3 x AFL and 3 x PFL immersive busses.”

He added, “With control connectivity via IP, surfaces can be physically remote and connected over standard networks using COTS hardware. Above all else, it gives our customers a very powerful suite of broadcast features, which will take them into the next era of broadcast workflows.”
