CALREC AUDIO HYDRA2 - A POWERFUL NETWORK FOR TOMORROW’S PRODUCTION NEEDS
THE ROUTE TO INTEROPERABILITY - FULLY INTEGRATED THIRD PARTY PROTOCOLS
Hydra2 encourages several third party control protocols. The SW-P-08 protocol allows router
control from third party router panels. It enables remote control over source to destination crosspoint patching. In addition to direct routing of physical inputs to outputs, it can also route to and from a console DSP via Calrec’s Hydra Patchbays. EMBER enables further system control
Hydra2 links the Apollo, Artemis and Callisto consoles to their integral crosspoint routers, and on to more complex networks if required. Offering up to 512 bi-directional channels of I/O per copper or fibre connection, Hydra2 offers true ‘one-to-many’ routing and allows the construction of large-scale distributed mixing networks with multiple control surfaces and routers/processors. The Hydra2 control software makes connecting resources very straightforward. Audio interfaces and consoles may be added and removed without the need for manual intervention making new resources available to console operators instantaneously. Hydra2 also features Hydra Patchbays,
which are virtual I/O within the Hydra2 domain allowing console operators to make console outputs available to other users on the network, as well as sources on mixing console inputs, and feeds to output ports, to be changed remotely – and without using up physical I/O or requiring extra cabling. Hydra Patchbays are a powerful tool for
control room and studio resource management, allowing network administrators to be able to put control rooms “on-air” and to manage the sources available to them.
allows consoles with relatively few physical controls to drive a much greater number of channels, busses and outputs.
SOLID YET FLEXIBLE
Despite the shift towards networked audio solutions, some things never change. 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.
Multiple control surfaces can also be connected to the same rack to allow multiple operators access to the same processing resources. A separate submix can be created in another location which feeds audio directly into the same busses output as the main mix without ever leaving the system. This gives broadcasters increased flexibility without the need for additional hardware.

including loading user defined memories, selecting I/O port alias files used by control surfaces, editing H2O I/O box and port labels, viewing the available metadata sets and selecting them for insertion into any Hydra2 SDI embedder output stream and muting selected audio channels in an SDI embedder output stream. The Calrec Serial Control Protocol offers mixer control to 3rd party video switchers and automated production controller technology, which allows visibility into and control over a number of Calrec console settings such as fader position, PFL and cut control for paths on faders, routing to auxes and mains from faders, output level control for auxes and mains, and LB/RB input switching for paths on faders. Interoperability, the concept of data
being shared freely between video and audio equipment, is increasingly seen as central to future audio networks. Transport protocols such as AVB and Ravenna continue to develop and mature, and Calrec will continue to take an agnostic approach to these technologies with a view to providing greater interoperability to its customers.
