Both [Measurement Group 1] and [Measurement Group 2] can be set so that measurement is performed as
follows.
- The loudness values of 2ch and 5.1ch can be measured together. (For example, set L-ch1, R-ch1 and
[Downmix]- No to [Measurement Group 1], and L-ch3, R-ch4, C-ch5, LS-ch7, RS-ch8, and [Downmix]- No to
[Measurement Group 2].)
- 5.1ch output and the downmix processing result can be measured together. (For example, set L-ch1, R-ch2,
C-ch3, LS-ch5, RS-ch6, and [Downmix] - [No.] to [Measurement Group 1], and set L-ch1, R-ch2, C-ch3,
LS-ch5, RS-ch6, and [Downmix] - [Equation - 2] to [Measurement Group 2].)
- In mono measurement, the same output channel is assigned to both L/R.
