5.1 > mono
In the 5.1 to mono downmix,
the attenuation values are:
Table 2.14: 5.1 to mono downmix pattern
LRCS format
A control room set up for 5.1 can be set up to
use an LRCS configuration without repatch-
ing the speakers. This is possible, since the LS
and RS speakers are assigned the same signal,
thereby creating a “phantom” CS speaker
(attenuated by 3dB).
The default is the LRCS rear hard speaker
configuration, where the LS(S) signal is
assigned to the CS speaker of a 6.1 configura-
tion (not shown above).
LRCS > stereo
In the LRCS to stereo
downmix, the attenuation values are:
