From some year part of the Ermitage Records catalog has been enriched with a new format: The Master Tapes. Thanks to the cooperation with Hemiolia Records we show the music as you’ve never heard it before: made in 1:1 copy mode using two Otari MTR 15 recorders with optimized calibration of the recording unit on each single white tape used. All Hemiolia Records Master Tapes are accompanied by an A4P (Analog Four Phases) certificate of authenticity which guarantees complete analog coherence in every production phase and are made using exclusively production masteres (First Generation) in stereo, 2 tracks – 1/4′ as a source.
