On the occasion of the feast of December the 8th , it was inaugurated the new audio plant within the Sanctuary of Our Lady of the Snows in Domodossola (VB). The system, designed and made by BL Acoustics with professional materials of their own design (www.blacoustics.net/catalog), provides excellent speech intelligibility of the priest at every point of the audience with the use of just two controlled directivity speakers. .
