TASCAM DS-M7.1 25
7 – Downmixing
Downmixing, as explained earlier, is the process of
folding a surround mix into a format using fewer
channels. This is done for the purpose of checking
compatibility.
Downmixing is enabled and disabled on the DS-
M7.1 using the
DOWN MIX/MONO key under the
SPL readout and control. When downmixing is
active, the key is lit (it flashes in mono downmix
mode, see below).
The settings for downmix are made using the
DOWNMIX function key.
1 Press the
DOWNMIX function key so that the
screen shows something similar to the follow-
ing:
2 The first parameter, Pattern, sets the
downmix “folddown” pattern. The patterns
available here depend on the source format
currently in use:
Depending on the value picked here, the other values
(that is, the amount by which the source busses are
attenuated before they are folded into the target bus-
ses) will change.
Note that some busses may pass through more than
one attenuator before reaching their destination.
These patterns are shown graphically, with an list of
the parameters and options available in each pattern.
The default downmix pattern for all source patterns is
LR.
A note on the mono downmix
The mono downmix is accessed using the shifted
DOWN MIX key. When the SHIFT key is held down
and the
DOWN MIX/MONO key is pressed (whether it
is currently active or not), the mono downmix is
enabled.
Pressing the
DOWN MIX/MONO key while it is flash-
ing returns it to its previous status.
