Symetrix Jupiter Enhances Audio at St Ann’s Church

Dating from the 1890s, St Ann’s church in the Welsh seaside town of Rhyl now boasts a thoroughly modern audio-visual system built around a Symetrix Jupiter audio DSP courtesy of Richard King Systems. The powerful DSP platform hides all of the complexity from the end user leaving them with a simple to operate audio system that has improved speech intelligability and music playback in the historic building.

As well as improving speech intelligibility, a key requirement for the audio refresh was that the installed system would be easy to operate for non-technical people. For this reason, Richard Hughes of Richard King Systems chose to build the new solution around a Symetrix Jupiter 12 processor. Richard explains, “often we see churches of this size being fitted with a traditional mixing desk but the plethora of buttons, knobs and faders can look like the bridge of the Starship Enterprise and very intimidating for the average person; with Jupiter we can hide all of that complexity”.

Three AKG gooseneck microphones and three MIPRO wireless microphones are fed in to a Jupiter 12 where the input processing section offers five bands of EQ, a dynamics processor with compressor, limiter and AGC, and a feedback fighter. Jupiter’s gain-sharing automixer ensures a natural sounding mix when multiple microphones are in use.

Although microphone mixing has been automated, it is sometimes desirable to mute or adjust the level of a particular microphone. To make this foolproof, CUK’s application Engineer, Fraser Sanaghan, created a custom SymVue interface that only presents level and mute controls to the operator and runs on an off-the-shelf Microsoft Surface tablet PC.

Processing for the speakers installed in the church is also handled by Jupiter; the comprehensive Speaker Manager on each output features eight bands of parametric EQ, high pass and low pass filters as well as 341ms of delay for accurate time alignment.
