Easily obtain a 10dB to 15dB improved signal-to-noise relation with the Cat.22 Dolby A card and to to 25dB noise reduction with the included Cat.280 Dolby SR (Spectral Recording) card for a dynamic range in excess of 90dB on most professional and prosumer reel-to-reel recorders.
Dolby Spectral Recording (SR) and Dolby A are considered far superior to DBX noise reduction without dulling recordings with a mask/veil.
The (2) Dolby Cat.22 included may be “modded” (aka vocal stressor)at the buyer’s request or add (1) “modded” Dolby Cat.22 cards for just €100.
Modding the encoder of Dolby A cards was a common practice in the 1960s and 70s to emphasize higher frequencies during recording tand thus add ‘air’ to vocals for a more transparent sound. The effect is accomplished by disabling two of the four compression bands: Band 1 (below 80Hz) and Band 2 (80Hz to 3kHz).
