Following on from its new Argo audio mixing control platform launched at IBC 2022, Calrec announces 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.

The industry has seen a significant uptake in IP, but not without cost constraints. The introduction of ImPulse1 is making the move to IP much more attainable, 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.

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.

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.
