Both remote broadcasting and remote working have had accelerated learning curves. Many sports productions, for example, are being mixed remotely or via virtualized surfaces. Smaller consoles like Calrec’s compact Brio have been used as remote work surfaces from mixers’ homes to provide live on-air mixing, and Calrec’s Assist web GUI has been implemented with Apollo, Artemis, and Type R work surfaces, as well as with virtual cores like VP2 and Calrec’s ImPulse IP engine, to provide control on a web browser from remote locations. Meanwhile, the modular Type R IP console is increasingly used for virtualized production on dedicated hardware, along with the Assist web interface. Calrec’s RP1 continues to provide comprehensive remote-broadcast capabilities and local IFBs at a remote venue from a centralized studio environment.

Calrec ImPulse audio processing and routing engine

As the industry continues to converge on IP workflows, Calrec has introduced more products to meet the need. Its IP ImPulse core has a native SMPTE 2110 backbone and is compatible with existing Apollo and Artemis control surfaces to provide an upgrade path to IP infrastructures. ImPulse is fully NMOS IS-04/05–compliant, which is critical to unifying IP workflows from different vendors, and features 3D immersive path widths and panning with full monitoring and metering and height and 3D-pan controls. Upgrading to IP infrastructures still requires careful planning; Calrec’s Gateway products smooth the transition and allow more flexibility at multiple outside broadcast events where both proprietary and IP networks are used. Both H2-IP Gateway and the AoIP modular I/O controller card are SMPTE 2110–compatible and provide an interface between Calrec Hydra2 and IP networks to allow control data and audio labels to be passed in both directions.


DiGiCo Quantum 225

Launched in February, the Quantum225 is DiGiCo’s newest digital audio-mixing console and includes 72 input channels with 36 busses plus a master bus and a 12×12 matrix. There are four MADI ports and dual DMI ports for added connectivity (Dante, Hydra, AES, Waves, etc.), as well as 8×8 analog and four AES channels for local I/O, built-in UB MADI, optional optics and Waves SoundGrid, plus dual PSU. The Quantum225 incorporates several Quantum features: Mustard processing-channel strips, Spice Rack plug-in–style native FPGA processing options, Nodal processing, and True Solo. When specified with the new 6RU DQ-Rack with integrated Dante, the system meets the demands of an AoIP networking environment. Other amenities include a 17-in., 1,000-nit TFT multitouch screen plus 41 additional mini TFTs, 25 100-mm touch-sensitive faders, and a custom-designed, multipurpose mounting bracket that can accommodate an additional channel or overview screen, laptop, KLANG:controller, or other device.
