Andrew Hills, Studer: Creation of Vistonics user interface is greatest innovation in audio mixers in the last five years

Modular solutions designed to grow with you

Gordon:We have always believed the

size of a console should not limit its processing capabilities. Our SD10-24 is a compact frame, but can still process the same amount of channels and busses. We have recently introduced ‘multi-channels’, which allows you to fold, for example, the six 5.1 sources under one fader and unfold them on to the surface when you need to adjust any parameters. We can fold up 11 sources under one fader, so in a music environment you

Jenkins: SSL’s C100 was fully 5.1 compliant when first released in 2003. Out of the box we had single fader 5.1 channels complete with full surround EQ, compressors, and limiters as well as multi-fader spill. Dual 5.1 program busses and surround monitoring were also standard features. We have subsequently added user control over the 5.1 downmixing coefficients, stereo to 5.1 upmixing, and an integrated 5.1 media player to the surround feature set.

“With improvements in audio processing power and console features, the challenge is to maintain speed of operation and easily accessible controls”

could have all your drum microphones under just one fader. Hills: Weight and mechanical stability is an issue with OB use. The packing of ever more transistors on to single chips helps both of these factors greatly. In 1985 a stereo DSP channel required a board 30cm square and 1,000 chips. Nowadays, a board 10cm square with six chips can provide 96 DSP channels.

TVBEurope: How are you gearing up (or have already geared up) to handle the increasing demands for 3D production with associated 5.1? Green: For 3D broadcasting, many

live events are now covered by not one, but two OB trucks: one for the 2D mix, the other for 3D. While the audio kit might be the same and both tend to mix in 5.1, the mixes are quite different. One is for a standard HD output, the other for what we now call 3D audio. Calrec’s Hydra2 networks are designed to move such audio around very efficiently, with resources being instantly available to all consoles on the network. This connectivity can be expanded to MADI (Multichannel Audio Digital Interface), too. In fact, more and more trucks in this kind of set-up use MADI to transport signals between units.

Nemes: One major point is

integration in order to save space. For example, Stagetec Nexus today not only serves as audio matrix, but also takes over HDSDI embedding and de-embedding, Dolby E encoding and decoding etc. This makes things very compact and space saving in the OB truck.

TVBEurope: Is there a trend towards incorporating what, previously, would have been considered sub-mixers into the main consoles? Gordon: As larger consoles do more,

the requirement for sub-mixers is less - but we have seen the SD11 become an ideal sub mix solution. It is able to mount into a 19-inch rack, but can still output and monitor 5.1. Hills: Yes and no. The large number

of channels available in today’s mixers means that the need to bring in extra ‘side consoles’ for large LE shows is a thing of the past. However, it is simply not possible to have a single sound operator provide all the mixes (main 5.1, main stereo, PA, monitor and grams) required on a large TV show. It is also much safer to have different mix engines and control surfaces providing these mixes.





When it comes to digital KVM, G&D thinks of your future. Our systems can be combined and cascaded, allowing them to fi t and expand to any sized installation through an infi nite number of versatile modules. So you can keep growing without having to constantly reinvest in new systems.

Our new DVICenter DP64 matrix switch has 64 dynamic ports to allow fl exibility in connecting either a computer or a user console to each port. Hence, multiple computers and platforms can be controlled by teams of users simultaneously. The system provides crystal clear digital images with transmission distances of up to 560m using CAT cables or up to 10 km with fi ber optics. It also comes with a superior user interface, easy intuitive confi guration and the extra assurance of a built-in monitoring function.

With digital KVM systems from G&D, your future’s looking good – and geared for growth
