From Sweden to Italy: The Remarkable Journey of a Mint-Condition Console

The emulations included in the Sand 4 Ultra suite are the result of a resampling of a console in near-mint condition, a real gem located at Digital Lake Studio S.r.l. in Italy. This console has an interesting origin, having been commissioned from Sweden. Swedish Radio Television ordered 12 nearly identical consoles between 1994 and 1997. The sampled console, dated 1997, was installed in a mobile broadcast van (OB Van) based in Instad, in southern Sweden. It was used approximately three days a week for two years before being decommissioned. Prior to its transfer to our studio in Italy, it was finely calibrated to a tolerance of 1/10 of a dB between channels using a sophisticated and highly professional system, and it has always been meticulously maintained to keep the mixer in perfect technical and functional condition. As it was commissioned by a broadcaster, it features several customizations tailored to its use, including a master section that is more compact to fit within the 200 cm width requirement of an OB Van.
