The second is an analog sensitivity control with three settings (Low, Mid, High) to match speaker sensitivity to source output voltage. The third provides sound adjustment with three tone settings: Dark, Neutral, and Bright. I preferred Neutral with most music and Dark with certain ’70s pop albums and early digital recordings. The fourth knob is a room-position control with three settings—Wall, Corner, and Free—to adjust for speaker placement near (or not near) room boundaries. The fifth knob offers sample rate conversion, which can be set to leave the source sample rate intact for the highest sound quality or to convert the files to enable gapless playback of tracks with different sample rates. The sixth and final control is a light switch that sets the illumination of the Y-shaped Dynaudio logo on the front of the stand to Off, On, or Dim. The light glows white during playback, flashes red if there’s clipping at the analog input, pulses red rapidly if thermal protection is activated, and extinguishes itself after 20 minutes without a signal. I never saw it turn red.
