Russia’s inaugural Formula One Grand Prix race was hosted at the new Sochi Autodrom in 2014. One of the world’s most modern circuits, the technical infrastructure required more than 15km of fibre-optic cabling for which Riedel was heavily involved in creating the specifications for the television production requirements and provided the circuit’s infrastructure for video, audio and intercom systems.

Sochi Autodrom‘The circuit in Sochi is currently one of the most modern in the world, equipped with state-of-the-art broadcast and racing technology,’ says _wige Solutions VP, Thomas Hellemann. For this prestigious project we partnered with Riedel for their specific know-how and more than two decades of experience in motorsports.’

During the Sochi Autodrom project, Riedel worked independently and with general contractor _wige Solutions, a Nürburgring-based company that specialises in media technology (lighting, sound and video), graphics and results services, and race services. The company was responsible for track surveillance and monitoring, time keeping, race control, marshalling and overall technical design. In order to establish a secure communications infrastructure, it opted for Riedel’s Artist digital matrix intercom to provide race control and marshall communications. For the dispatcher system, a Motorola Tetra was directly integrated into the Artist.

As with all other F1 meets, Riedel supplied its communications and signal transmission solutions, including special headsets for radio and intercom systems, the IT infrastructure, and access management. This included more than 500 Artist keypanels and 1,500 Tetra radios used by Formula One Management, Formula One Administration, the Fédération Internationale de l’Automobile, and the Formula One race teams.

‘Following a successful Winter Games, our return to Sochi to work on the F1 course was like a homecoming,’ says, Riedel Director of International Projects, Kai Olaf Houben. ‘It gave us a distinctive home field advantage in completing the Sochi Autodrom project. The smooth interaction and absolute reliability of our communications systems, and a qualified team with experience, are essential in Formula 1, especially with regard to safety. We always have one thing in mind: an absolute zero tolerance for errors in the communications. At the first GP of Russia, we have again demonstrated the quality and reliability of our solutions, and showed that we are the right partner for permanent racing and broadcast infrastructures.’

Sound Devices has released Firmware 2.10 software for its 970 audio rack-mounted and PIX 250i, PIX 260i and PIX 270i video rack-mounted recorders.

New features and upgrades include enhanced metadata functionality, sound report creation and improved file/folder formats. In addition, Sound Devices now offers a Release Candidate Screening Program, which gives existing users of its rack-mounted recorders a preview of features and changes under development in the firmware.

Firmware 2.10 features a new Metadata screen that allows users recording audio to access and edit the Scene, Notes, Take and Circle status of Previous, Current and Next takes. It also provides the same metadata editing functionality from PIXNet, the Web browser interface. Additionally, the PIXNet clips tab now display information about recordings, including start time code, fps, user-bits, duration, codec and audio format.

With regard to reel folder formats, in previous iterations of the firmware, a Custom option enabled users to edit reel folder names with any alphanumeric value, whereas the 2.10 firmware offers a second Daily option. If set to Daily, new reel folders will automatically be named with the current system date in the YYMMDD format. These daily reel folders, which are containers for the recordings, are helpful in organising deliverables for projects that span multiple days. This latest firmware also features a new Phrase List Manager, which lets end users create a list of commonly used phrases and then use them to quickly edit the Notes field of recorded WAV files. Users can also now enter notes from either the File list or the new Metadata screen, for the next recording.

For those devices operating in Audio Only Mono mode, it is now possible to have the system append the actual audio track name to the end of the file name. While recording, track names can now be edited from the audio screen and from PIXNet. This assists those in postproduction in determining which audio file is associated with which member of the cast, a feature that is particularly useful in high-track-count reality shows. In addition, the new Sound Reports feature creates CSV files based on WAV-file metadata.

The Release Candidate Screening Program provides the company with direct customer input on the usability of its updates, ensuring the stability of firmware updates in real-world applications. Initially, the programme will target the Video Devices and Sound Devices rackmount products, with the company planning to expand it to other product lines over time.

‘The goal of our new screening program is to work together with end-users to identify and resolve any potential stability issues and get feedback on product performance in real-life workflows, so the best possible firmware makes it into upcoming official releases,’ says Dan Desjardins, Manager of Software Development & Quality Assurance ‘Sound Devices enjoys a highly regarded, open-door relationship with its customers worldwide, and this programme promises to expand on that bond.’

Each Release Candidate will come with a pre-determined expiration date and limited technical support. Firmware 2.10 is available as a free download for all existing rack-mount products.

Clear-Com has released the Linq series of comms interfaces, enabling connection of two-wire partyline with call signalling and four-wire audio over LAN, WAN or Internet IP infrastructures.

Clear-Com LinqBased on Clear-Com’s IV-Core technology, Linq is available in two-wire (Linq-2W2) or four-wire (Linq-4W2) options. The Linq-2W2 is both Clear-Com and RTS TW compatible. The Linq-4W2 can interconnect with devices, such as analogue ports of any matrix intercom system, analog telephone circuits, two-way radio gateways and audio consoles. A maximum of six Linq IP interfaces can be linked together in any 2-wire or 4-wire combination.

Linq uses the Opus high-quality audio codec, allowing bitrate, bandwidth and delay to be changed quickly without introducing distortion or discontinuity in the audio. As a low audio latency communication link, Linq can be used for natural intercom conversation, networked music performances and for audio signals that are transported via different facilities (transmission sync).

The creation of virtual partylines within a linked group is an exclusive feature. Channels from any of the six devices in the network can be linked to create common virtual partylines. At least two channels must be associated to each other. Linq uses a touch-friendly web-based user interface to configure, control and monitor any device within a linked group.

‘Linq is a simple yet significant development that enables users to expand their remote communications quickly and easily,’ says Clear-Com Product Manager, Stephen Sandford.

Tascam DR-60D MkIITascam has announced the DR-60D MkII four-track recorder for video production.

Designed to be mounted to a camera, the updated recorder is equipped with new microphone preamps with up to 64dB of gain, and its two XLR mic inputs and two stereo inputs can be recorded individually. A Dual Recording mode captures an additional safety track.

The HDDA mic preamplifiers (High Definition Discrete Architecture) employ discrete circuitry and premium parts, and achieve a high EIN (-120dBu) using Cirrus Logic AD converters. It can record up to  four tracks simultaneously, allowing multiple microphones to be used while filming. Inputs 1/L & 2/R can be selected for mono or stereo link operation.

Three sets of stereo outputs are provided. A Camera Out sends a reference track recording to the camera. The Line Out can feed a mixer or recorder. A Headphone Out is available for direct monitoring. Each of these outputs has its own level control, and the Camera Out can be attenuated to microphone level without the need for an attenuating cable.

The DR-60D MkII has an internal digital mixer fowith pan and level control. It is also equipped with a limiter or high-pass filter (40/80/120Hz), and set individual channel delay.

A variety of recording modes are supported:

· Mono/Dual Mono mode for single source microphones.
· Stereo/Dual Stereo mode for shooting with a stereo or mid-side (MS) microphone.
· Internal MS decoding can be added during monitoring or before recording.
· 4CH mode records all four microphone inputs to their own tracks.
· Dual Mono/Dual Stereo mode records a safety track from -6dB to -12dB below the initial take.
· Remote Jack accepts either the RC-3F footswitch-type remote control or RC-10 wired remote control.

The Channel 3/4 input connector supports a high-level maximum input – up to +10dBV. Many microphones designed for use with video cameras have a high-level output and a 3.5mm output connector. Plug-in power is also available for microphones.

The keys of the unit are designed for quiet operation to eliminate handling noise and the Slate feature is designed to mark tracks while in production.
