Calrec has announced its new ImPulse1 IP audio processing and routing engine — a smaller, yet powerful cost-effective ST2110 version of the industry-established ImPulse.

ImPulse1 is a compact 1U solution with an optional second core for redundancy and a new 128 input channel DSP pack offering entry-level pricing.

Since Calrec’s ImPulse IP core was debuted four years ago, the industry has seen a significant uptake in IP, but not without cost constraints.

With the introduction of ImPulse1, Calrec is making the move to IP much more attainable for all its customers, offering a range of options to suit all budget requirements.

ImPulse1 works with Argo Q and Argo S control surfaces, and/or Calrec Assist, a browser-based GUI, ideally suited to remote working, multi operator and/or headless operation. Cores with smaller DSP licenses can be offered without hardware redundancy.

Dave Letson, VP of Sales at Calrec said, “Broadcasters are under pressure to improve workflows in the move to ST2210 and reduce costs whilst still demonstrating ROI.

“With this in mind, we have introduced a cost-effective and compact 1U solution with an optional second core for redundancy and a range of DSP options, including a new 128 channel DSP pack.”

ImPulse1 is designed for small to medium single mixer applications and is offered with an all-new DSP license of 128 input channels without compromising its ST2110 capability.

With a small overall form-factor, it’s immediately attractive for compact installation sites, such as outside broadcast and fly pack applications, where space is at a premium.

Furthermore, it doesn’t compromise on features and DSP power; it has DSP options ranging from 128 to 384 input channels and benefits from the DSP features from the larger ImPulse core.

Calrec is continually adapting to changing production needs, with the launch of Argo, transforming how broadcasters configure and use their control surfaces and now ImPulse1 which provides powerful, less expensive options for Argo and/or Calrec Assist.

Argo has been built around an expanded version of Calrec’s ImPulse and ImPulse1 cores. IP connectivity allows for processing cores to be remote from surfaces and backup redundant cores.

Letson added: “With the addition of Argo and ImPulse1, we are able to help broadcasters of any size navigate the move to ST2110 with a range of solutions, price points and a pace that suits them.”

ImPulse1 features include a fully self-contained DSP core as well as dual AC PSUs. Twin core hardware redundancy or optional single core systems are available with ST2022-7 as standard. Other main ImPulse1 features include:

–        Up to 672 processing paths

–        Native AES67 / SMPTE ST2110-30 connectivity

–        ST2110-30 connections can operate in 1 or 10Gbps mode

–        Built-in support for NMOS IS-04 advertisements & IS-05 connection managements

–        Max router capacity of 2,048 x 2,048

–        Up to 512 ST2110 streams – each stream can pass between 1 to 80 audio channels

Surface connectivity is via IP, so surfaces can be physically remote, connected over COTS networks and supplemented with Assist web UI for multi operator, remote or headless use.
