6 - Surround modes
Because the TM-D4000 is capable of mixing to sev-
eral different surround modes, some of the operations
and display screens are slightly different from the
“normal”, stereo mode, as explained here.
Some of these operations are also explained in other
parts of the manual, but are gathered here for easy
reference.
In all cases where a surround mode is selected, the
output busses are used to control the levels of the sig-
nals sent to the different channels of the surround
matrix.
6.1 Selecting a surround mode
This selection is made through the

A plan view of the speaker layout is shown on
the display screen.
Note that in the 5.1 screen, the two rear
speakers can be selected as a single mono
output.
6.1.1 Selecting a buss pattern
As mentioned earlier, the output busses are used to
control the levels of signals sent to the surround
matrix channels.
In this context, they can be regarded as “super-stereo
master” controls.
The assignment of the busses to the channels is
shown by a number beside the representation of the
on-screen speakers.
The surround buss assignments below each surround
mode type allow the assignment of different buss pat-
terns to the surround channels. Where a channel does
not exist as part of a surround mode pattern, it is rep-
resented by a dash (–).
