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.

Press the

DOWNMIX

function key so that the

screen shows something similar to the follow-
ing:

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.
