CONCRETE RESOLUTIONS

1R Melbourne is located at the new Capitol Building in the hub of South Yarra. Spanning a total of 800sqm, every aspect of the design (by Foolscap Studios) and fitout is meticulously thought through.

“We inherited the space after the building work had been done, which includes consideration for reduction in audio transmission between studios and from the club to the rest of the building and residents upstairs,” explains David Gilfillan.

“Getting even coverage across the studio floors was really important,” continues Avivo’s Peter Ivanoski.

David Gilfillan mapped the three main rooms in EASE, to predict and optimise direct field coverage. A distributed system was necessary to avoid too much variation in level, and because of the unusual room shapes.

“Two of the rooms are narrow with low ceilings. To help keep reverberation under control, we were offered a fixed amount of acoustic absorption for the club. It was not quite enough, but we developed a plan to install the material to the surfaces where it could have most effect,” explained Peter.

Achieving a nightclub audio experience in sealed concrete bunkers is tricky but with the aforementioned acoustic treatment and a carefully positioned loudspeaker system, it’s possible. But fitness centres have an audio sting in the tail: instructors need to speak over the music. 1R’s Catharine Rose sets the scene: “There can be up to 40 people in a session at any one time. The instructor’s role is keep everyone safe, and they are guiding patrons through the program and cueing music and lighting. They are controlling the volume of the sound, selecting the lighting programs, and through their instructions they are also really helping to provide the energy.” Almost like a cross between a ring master and a lifeguard.

Avivo specified the industry standard headset mic, the AeroMic — which is well known for its robust manufacture and high resistance to sweat and moisture. But that’s only half the solution. Peter Ivanoski explains: “In an environment like this it is really difficult to lift speech over the music. I’ve seen lots of clubs try. Often you’ll see instructors yelling to be heard over a big-box PA, and they will distort the mic channel, and you’ll get clipping, and things get ugly very quickly.”

For a project where the quality of the audio is paramount, Peter and David couldn’t cross their fingers and hope there would be enough gain before feedback to be heard over the loud music. Instead, they proposed a design that borrows from an old theatrical technique: give the speech channel its own signal path independent of the music playback system.

The resulting audio design in the two long spaces sees Martin Audio CDD6s dotted down both sides of the room for speech, interspersed with CDD8s for music. A further four Martin Audio Blackline X210B double-10-inch subs complement the music.

The squarer, ‘Rumble’, punching bag room uses fewer CDD10 for music and CDD6s for speech.

“Gyms want that experience of a big nightclub sound thumping away at their chest, plus the voice of the instructor over the top, and that’s really hard to achieve, particularly when the instructor is walking around inside the listening area,” explains David Gilfillan. “Having the independent channel for speech helps us refine the speech component. Why don’t more people do it? Cost, mainly, but also, it’s tricky to set up. Once you factor in the extra cost of the speakers, the wiring, the amplifiers, the installation time, the architectural impact and the commissioning, it’s a significant cost. But for 1R, it’s totally worth it. When Peter and I pitched our ideas and concepts to Fitwork and 1R, they were on board from the start. They immediately saw the potential benefits and gave us the green light to help them create something special.”
