Our reference is simple, we listen to the sounds of instruments in the recording spaces we have designed, and then walk into the control room, where we have designed the control room, the amplifiers and the loudspeakers. Listening there, and then walking back to the real thing to listen again, means you also have to optimize the microphone placement and type. This kind of quick reference to live sound is obviously a luxury most people or manufacturers do not have. However, it also makes us even more critical of our own products than our audio customers are. Stated simply, the sound of a single note played on a well tuned Steinway grand piano in the FOCUS Recording Studio is so refined and complex. As an audio manufacturer, it makes you feel very humble when you then listen to the reproduced sound in the control room. This 250m2 recording room has been designed in the shape of the grand piano. This shape of music instruments is the result of experiments and careful listening over many hundred years, and the piano shape does give a superb even spread of resonances in a room, which supports the sound of the grand piano so well. As far as we know, this piano shaped recording room is the only such room in the world. FOCUS will allow visitors in there from time to time, so if you are in Copenhagen, do give them a call.
