Lawo said two identical on-air studios were built for Fuzhou Radio. Each is equipped with a 12-fader ruby mixing console, backed with Lawo’s Power Core, an AoIP mixing engine available to radio stations. Fuzhou Radio also equipped the studios with Electro-Voice RE27 and Shure MX 418 microphones, Genelec 8030 monitor speakers, Eventide BD600+ broadcast delay systems, and Infomedia AOIPBox terminals.

Fuzhou Television has worked with Lawo before, installing an mc²56 on its HD OB van. Jochen Richter, Lawo Head of Sales, Radio, said that when Fuzhou decided to renew their radio studios and adopt AoIP, they found the Lawo ruby mixing console perfectly suited to their needs.

“More and more broadcasters are realizing the benefit of audio networks based on standards rather than proprietary protocols,” he said.

The ruby console features the Power Core DSP mixing engine as well as multiple MADI and AES67 interfaces that provide access to as many as 384 channels of stereo audio, standard. This, Lawo said, makes it the perfect bridge between baseband and AoIP audio operations.

Eight plug-in slots accommodate additional I/O via mic, line, AES3, HD MADI and Dante expansion cards. When paired with a Lawo ruby mixing console, Power Core can provide as many as 96 DSP channels for precision audio shaping, with up to 80 summing busses, multiple AutoMix groups, and comprehensive compression / expansion / de-essing tools. It also has dual, redundant NICs with SMPTE 2022-7 Seamless Protection Switching to ensure instant, inaudible recovery from network faults.

Lawo’s complete line of physical and virtual radio solutions include the ruby radio console, sapphire, sapphire compact and crystal mixing surfaces, crystal Clear and RƎLAY Virtual Radio Mixers, and VisTool GUI-builder software.
