TASCAM DS-M7.1
LCRS format
As mentioned earlier, there are two LCRS configura-
tions. The first is the LCRS (LS, RS) configuration,
This allows a control room set up for 5.1 or 6.1 to use
an LCRS configuraiton without repatching the speak-
ers. This is possible, since the Ls and Rs speakers are
assigned the same signal, thereby creating a “phan-
tom” Cs speaker.
The second is the LCRS (CS) configuration, where
the LS(S) signal is assigned to the CS speaker of a
6.1 configuration.
Both configurations use the same downmix settings,
as shown here.
LCRS > LR In the LCRS to LR (stereo) downmix,
the attenuation values are:
LCRS > mono In the LCRS to mono downmix, the
attenuation values are:
