Story Highlights

Remote audio-mixing consoles for broadcast are still a relatively small category at the high end of the market, but there's great diversity within the group, thanks to increased demand for consoles in a variety of sizes and functionality. Here's an overview of the leading offerings.

Calrec Calrec Impulse audio-processing and -routing engine

The Assist web GUI is implemented on Calrec's new Argo Q and Argo S configurable control surfaces, as well as on Apollo, Artemis, and Type R consoles to provide remote control from a remote location. It's also available on the RP1, which continues to provide full broadcast capabilities at a remote venue from an established studio environment.

Calrec's IP-based ImPulse core has a native SMPTE 2110 IP backbone and a defined path for broadcasters to upgrade to an IP infrastructure. ImPulse is compatible with existing Apollo and Artemis control surfaces and Calrec's new approach to audio mixing - Argo Q and Argo S - and is NMOS-compliant, which is critical to the unified workflow of products from different manufacturers. For broadcasters producing live content in immersive formats over platforms like MPEG-H and Dolby Atmos, ImPulse also provides 3D immersive path widths and panning, with full monitoring and metering and height and 3D-pan controls.

Calrec has also introduced a smaller yet powerful, cost-effective ST 2110 version of the established ImPulse. Designed for small to medium-size single-mixer applications, ImPulse1 is a compact 1RU audio-processing and -routing engine with an optional second core for redundancy and a new 128-input-channel DSP pack offering entry-level pricing. ImPulse1 works with Argo Q and Argo S control surfaces and/or Calrec Assist, suiting it to remote, multi-operator, and/or headless operation.

In addition, Calrec's modular Type R IP-native mixing system is increasingly being used for distributed production. www.calrec.com/

Evertz Studer Vista digital mixing console

The Studer Audio portfolio, celebrating its 75th anniversary this year, continues to expand. Since acquiring Studer in 2021, Evertz has integrated the brand's Vista digital mixing consoles into its own Software Defined Video Networking (SDVN) platform. Now supporting SMPTE ST 2110, the consoles are an important addition to Evertz's live-production workflows. This year, Evertz has brought all the power of Studer Vista to its DreamCatcher BRAVO Studio virtual production-control suite, which allows users to quickly and easily produce high-quality live content at lower cost. The introduction of Vista BRAVO provides virtual access to a full mixing console featuring all the enhanced audio capabilities. With Vista BRAVO, users have the flexibility necessary to enhance sports and other productions, whether on-premises or through the cloud. For remote production, Evertz has expanded the Vista controls to its software-based VUE Intelligent User Interface, with more than 2,000 bidirectional controls. VUE mirrors the physical controls of a Vista audio console onto a software interface that is touch-enabled and accessible from any web interface in any location. Inclusion of Vista controls into VUE emphasizes the company's continuing efforts to integrate Studer into its eco-system. evertz.com/

Lawo Lawo mc mixing console

Lawo's mc mixing consoles - mc 96, mc 56, mc 36 - are focused on IP-based broadcast, AV, and live-production scenarios. They are available in multiple configurations for at-home productions, flypacks, production trucks, and large production facilities in on-premises, WAN-distributed, and hybrid deployments. Thanks to open standards like ST 2110, RAVENNA, and AES67, remote-production capability comes as standard.

The mc consoles integrate with HOME, Lawo's management platform for IP-based media infrastructures, which is designed to connect, manage, and secure all aspects and instances of live production. In addition to automatic discovery and registration, HOME provides centralized services for swift and effective interaction of engineers with their tools, whether manufactured by Lawo or other vendors that support the HOME API.

The mc consoles are powered by the A__UHD Core audio engine as the heart of a dynamic and distributed audio-production system. Distributed production approaches involving two or more audio engineers working from adjacent or geographically distanced locations can be used over secure WAN connections, regardless of whether a data-center-style resource-pooling strategy or a globally scattered network of A__UHD Core units is preferred. Software licenses are stored on USB dongles and can be downloaded for seamless transfers from unit to unit. The Pool DSP license allows operators to split the 1,024 available DSP channels across multiple consoles in a range of configurations for physical, virtual, and headless (automation-driven) control surfaces.

A wide range of IP-based audio edge devices is also available. The A__stage series accommodates users in search of high-channel-count I/O in a variety of formats (analog, AES3 digital, MADI); the single-format A__line devices are usually used in flypacks, mobile remote setups, and locations where only a few sources and destinations are used. PowerCoreRP is a remote-production solution for mc audio consoles with built-in modular I/O, DSP, and IP-streaming capabilities. Rear-panel bays allow users to add as many as eight I/O cards for additional audio inputs/ou
