The new “Green” ATM or Atmosphere Tuning Module is a significant breakthrough in acoustic resolution for the Synergistic Research Atmosphere Field Generator as well as being used on it's own within a listening room.
Compared directly to the original Red ATM the Green ATM is a faster resonator portraying acoustics and recordings with a lower noise floor for enhanced detail and air. Notes seem to decay into a darker background while the overall sound field seems to extend further in all directions; front to back, side to side and top to bottom. Use 1 Green ATM on the front wall, in close proximity, between your speakers or add a second Green ATM and place them directly on top of your speakers.
