Mozartsaal der Irnberger Foundation Salzburg

“The Mozartsaal der Irnberger Foundation (Mozart Hall of the Irnberger Foundation) is, so to speak, the ideal case. Here, with the help of first-class acousticians, a successful symbiosis of a concert hall with ideal room acoustics and a technically perfect recording studio was achieved. The natural reverberation times can be individually adjusted between 2 and 0.6 seconds using special acoustic curtains, making it possible to avoid the need for a reverberator. Adjacent to the hall is the recording studio, which is equipped with a high-quality listening system from the renowned Manger company. 24 shielded microphone cables from Belden with gold-plated Neutrik connectors run underground.”
