Downmix

  • Functions: surround to stereo, stereo to mono
  • Surround to Stereo:
  • L @ 0 or ・ dB;
  • i
  • R @ 0 or ・ dB;
  • i
  • C @ ・ or ・ dB summed with L and R;
  • /l
  • LFE @ full attenuation or ・ dB summed with L and R;
  • i
  • LS @ ・ or ・ dB summed with L;
  • /l
  • RS @ ・ or ・ dB summed with R;
  • /l
  • C, SUB, LS, and RS monitor outputs mute
  • Stereo to Mono:
  • L @ ・ dB summed with R @ ・ dB to C;
  • /l
  • L, R, LS, RS, and SUB monitor outputs mute
  • For a surround input this results in the C output being the sum of L @ ・ or ・ dB, R @ ・ or ・ dB; C @ ・ or ・ dB, LFE @ full attenuation or ・ dB; LS @ ・ or ・ dB, and RS @ ・ or ・ dB.
