Croatian Catholic Radio (HKR) has completed construction of all-new broadcast studios with Lawo mixing and routing technology at its heart.
Established in 1997, HKR is one of just half-a-dozen radio channels in Croatia, which are licensed to broadcast on a national basis. Programming originating from its Zagreb headquarters is heard across the country via terrestrial and online distribution. This installation is centred on four Lawo crystal mixing surfaces, a Power Core DSP engine, and Rǝlay VSC software were installed, with integration and commissioning provided by AVC Group.
‘After 20 years, HKR moved their studios to a new building,’ says Zeljko Pemper of AVC Group Zagreb, which performed the studio integration. ‘The broadcaster chose Lawo equipment because of its reputation for flexibility and reliability – after all, when you’re broadcasting to a national audience, there’s no room for error.’
The main on-air studio and its redundant backup studio are both fitted with 12-fader consoles, with twin four-fader crystals at work in the two production and editing suites and VisTool GUI Builder software providing context-sensitive screen displays for each of the four consoles. A Power Core DSP engine is used in the Tech Centre to provide system-wide routing and audio I/O, while multiple copies of Rǝlay VSC Virtual Sound Card software interface PC audio workstations with HKR’s Ravenna/AES67 audio-over-IP network.
‘Power Core proved to be the centre point of the entire build,’ Trsar says. ‘With hundreds of channels of AES67, analogue, Madi and AES3 capacity, dozens of DSP channels, a routing matrix with more than 1,900 crosspoints, plus SMPTE 2022-7 Seamless Protection Switching, we think that Power Core is an amazing tool for broadcasters large or small. What else can do so much in just one U of rack space?’
