Following on from its Argo audio mixing control platform launched at IBC 2022, Calrec has released 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.
Calrec says that the introduction of ImPulse1 makes 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 Calrec Assist, a browser-based GUI suited to remote working, multi-operator and headless operation.
Features
ImPulse1 features a fully self-contained DSP core and dual AC PSUs. Twin-core hardware redundancy or optional single-core systems are available with ST2022-7 as standard. ImPulse1 can provide up 672 processing paths with native AES67/SMPTE ST2110-30 connectivity and has built-in support for NMOS IS-04 advertisements and IS-05 connection management.
Its ST2110-30 connections can operate in 1 or 10Gbps mode, while ImPulse1 has a maximum router capacity of 2,048 x 2,048 and can process up to 512 ST2110 streams with each stream passing between 1 to 80 audio channels.
Surface connectivity is via IP which means that surfaces can be physically remote, connected over COTS networks and supplemented with the Assist web UI for multi-operator, remote or headless use.
Dave Letson, Calrec’s VP of sales, says, “Broadcasters are under pressure to improve workflows in the move to ST2210 and reduce costs while still demonstrating ROI. With the addition of the Argo and ImPulse1, we can help broadcasters of any size navigate the move to ST2110 with a range of solutions, price points and a pace that suits them.”
