Sonorus Audio produces the ATR 10, a reel to reel deck based on the chassis from the Revox PR99 . The ATR10 is a 1/4” REPRO machine (playback only, no recording) for hi-end music listening.
Electronically regulated tape tension, dual EQ (NAB and IEC), wire remote controlling and Library Wind (FF controlled speed to prepare tape for storage) are all new functionalities.
Sonorus builds the tape transport with original mechanical components from Revox/Studer. Internal electronics have been redesigned to use parts currently in production. The playback board is completely new, featuring a vacuum tube preamp section.
