Calrec launches smaller version of ImPulse, complete with ST 2110 core

ImPulse1 is ideally suited to remote working, multi-operator and/or headless operation, said the company

Calrec is launching a new version of ImPulse, the company’s DSP engine, that it says will make the move to IP more affordable.

The new ImPulse1 IP audio processing and routing engine 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, said the company.

The engine is designed for small to medium single mixer applications and is offered with an all-new DSP license of 128 input channels, added Calrec.

It has DSP options ranging from 128 to 384 input channels and benefits from the DSP features included in the larger ImPulse core.

Other main ImPulse1 features include:

  • Up to 672 processing paths
  • Native AES67 / SMPTE ST 2110-30 connectivity
  • ST 2110-30 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 ST 2110 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.

Dave Letson, VP of Sales at Calrec said, “Broadcasters are under pressure to improve workflows in the move to ST 2210 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.”
