Tascam DS-M7.1 用户手册

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.

In the LCRS to LR (stereo) downmix, 

the attenuation values are:

In the LCRS to mono downmix, the 

attenuation values are:
