The most important parameter when it comes to mixing is the listening environment in conjunction with some really high-end monitors. Only then can you be sure of what's really going on in the mix. It's all about definition, clarity, and being able to hear all frequencies on a detailed level. The listening environment, or control room if you like, here at Studio PH Sweden is acoustically engineered, built, and designed by Claes Olsson of EORA Sound Engineering. Claes designed the room with the Genelc 1237 in mind, ensuring absolute world class listening environment.
