Calrec, Putting Sound in the Picture
In the current fast paced, technologically progressive era, modern broadcasters demand more versatility and integration from their audio equipment. TV companies need to ensure that their systems can produce programmes efficiently and to required specifications. For their audio systems to be able to achieve this, greater consideration has to be given to their networks as a whole and how efficiently they can be controlled.
The Apollo, Artemis , Summa and Brio consoles all leverage the increased power of FPGA technology, providing more digital audio channels for 5.1 Surround production and more user-friendly control surfaces to deal with them.
Calrec consoles have an excellent reputation for reliability and on-air stability. Unlike many other consoles which claim redundant features, Calrec provides on-line redundant hardware for all critical systems as standard. DSP, router, processing and PSU cards are all hot pluggable and supplied with hot spares as standard, and are all contained within a single, lightweight, space saving, energy-conscious 8U or 4U rack.
With a simple 2U core with integrated I/O resources, a single core can power up to three independent mixing environments. Whether used as independent studio consoles, microphone processors or utility mixing, the ability to use multiple mixing engines combined with the flexibility of the AES67 compatible network, provide all the power you will ever need.
With a native IP Backbone, Type R provides an infrastructure for future expansion. It guarantees stations are not only able to keep pace with changing demands, but provides the facility to ignite their audiences with new and innovative programming. (more..)
Brio is the most powerful and compact digital broadcast audio console in its class. It has a comprehensive broadcast feature set to support a wider breadth of broadcasters, and the same market-leading levels of quality and customer support which Calrec is renowned for.
The smallest in Calrec’s Bluefin2 family, Brio’s control surface is unlike any other console. At only 892mm wide with a 36 dual-layer fader surface, Brio is entirely self-contained with analogue and digital I/O, and GPIO, built into the surface. Additional expansion I/O slots are also fitted to allow for further I/O to be connected. A Hydra2 module can be fitted to connect to and share audio over Calrec’s Hydra2 network. (more..)
Calrec’s elegant Summa console is designed for broadcast professionals who need to produce creative and engrossing broadcast audio easily, but may not require as many resources as Calrec’s Apollo and Artemis consoles. Control is via a 17-inch multitouch screen inspired by familiar tablet technology, with a straightforward interface that uses established finger gestures to navigate the system. Summa’s considered control simplifies even complex workflow tasks, such as creating mix-minus feeds. Bluefin2 technology gives Summa a pool of 180 or 128 channel processing paths, eight groups, four mains, 16 auxes, and 32 tracks. Its Hydra2 router core provides Summa with the same integral router technology as the Apollo and Artemis consoles. (more…)
The twin sister of Apollo in Greek mythology, Artemis is based on the award-winning Apollo platform. Available in three sizes and utilising the same Bluefin2 and Hydra2 technologies, Artemis has an enormous routing and processing capacity. Bluefin2 gives Artemis Shine 680 channel processing paths, 340 on an Artemis Beam and 240 on an Artemis Light, with up to 128 program busses, 64 IFB/Track outputs and 32 auxiliaries. Artemis Light packs all this into a 4U enclosure. Artemis’ integrated router means all I/O functions can be performed by Hydra2, using the same high capacity cross-point router technology and a variety of I/O units. (more…)
Apollo provides unsurpassed processing power and a control surface with displays, touch screens and light-emitting knobs which detail function and status. It utilises Bluefin2, the next generation of Bluefin HDSP, which provides unrivalled resources of up to 1020 channel processing paths, 128 program busses, 96 IFB/Track outputs and 48 auxes. With single and dual fader options, Apollo can squeeze in more faders into a single footprint that any other console, and its integrated router provides total network flexibility. Apollo’s I/O functions are performed by the Hydra2 network, which uses high capacity 8192² cross-point routers and a variety of I/O units. (more…)
Remote Production (RP1)
RP1 is housed in a 2U rackmount box, containing Calrec’s award-winning Bluefin2 processing.
Calrec’s RP1 provides local DSP to enable the generation of monitor mixes and IFBs with no latency. It gives an operator in a remote studio direct control over channel functions such as mic gains, aux send/monitor mix levels and fader levels. It also provides a mechanism to embed audio into existing backhaul technologies, such as SDI or SMPTE 2022.
All DSP and bus configuration can be carried out on-site using Assist, Calrec’s web-based configuration tool. Assist makes it simple for on-site engineers to set-up all IFB routing and remote monitor mix levels at the venue.
This enables venue infrastructure, routing and monitor feeds to be tested prior to transmission. Local DSP processing also means there is no latency for commentary or talent monitoring.
With all DSP processing for monitor mixes taken care of on-site, the studio transmission console is able to concentrate purely on the main programme mix. (more…)
ImPulse is a powerful audio processing and routing engine with AES67 and SMPTE 2110 connectivity. It is compatible with existing Apollo and Artemis control surfaces to provide a simple upgrade path for existing Calrec customers as they transfer to IP infrastructures.
With Blu3fin built-in, ImPulse has the most powerful DSP engine available and can switch between five different user-upgradable DSP packs. Future expansion will allow up to four DSP mix engines and control systems to run independently on a single core at the same time.
ImPulse provides 3D immersive path widths and panning for next generation audio applications. Height and 3D pan controls, flexible panning and downmixing are built in. (more..)
Hydra2 provides seamless, scalable audio networking of audio mixing consoles with routers and IO interfaces, allowing for a large numbers of inputs and outputs to be shared and controlled irrespective of location. Hydra2 does not compromise audio quality, performs with negligible latency and is founded on comprehensive, built-in fault detection and redundancy. Many of the world’s most successful broadcasters rely on Hydra2 infrastructure for live on-air application in both fixed and mobile installations every day.
Calrec’s H2-IP Gateway provides an interface between a Hydra2 network and an AoIP network. It awards an extra control level that allows audio labels to be passed in both directions between the two networks along with control data.
This gives Hydra2 users the ability to control gain of Calrec AoIP mic inputs, and AoIP users can control gain of Hydra2 mic inputs. The H2-IP Gateway is SMPTE 2110/AES67-compatible and expands Calrec’s range of AoIP solutions.
The 1U gateway can pass either 256 or 512 channels of audio in each direction and multiple gateways can be used to increase capacity or to connect with multiple networks. For full hardware redundancy additional units can be deployed as backups.
