Alpha Recording System (ARS)

Alpha Recording System makes specialist rotary mixers in Japan. Its ARS models provide control and mixing for vinyl-centred listening systems.

Design & approach

Alpha Recording System’s catalogue includes rotary mixers, crossovers, equalizers and parts. This places ARS at the control point between playback sources and the rest of a system. Its mixers appear in several profiled booths, where channel layout and rotary level controls shape the selector’s interaction with records and other sources.

  • Mixer: MODEL9900 rotary mixer (ARS / Alpha Recording System)

Inside the system

Bonsai’s signal chain puts the selector at the centre: the Technics decks feed the ARS Model 9900, while the GR-Research X-CS Encore speakers reproduce the main programme through the currently listed Sansui BA-2000. The sealed main cabinets and separate bass system allow the upper-bass and midrange presentation to be considered separately from the room’s deeper bass demands.
