5 – Channel modules : Surround operations
88 TASCAM DM-4800 User’s Manual
Surround operations
There are several screens and functions which
change from those described previously when a sur-
round mode is selected.
There are three surround matrices available, which
can be assigned and mixed differently, but each
matrix must be of the same format (for example, it is
not possible to have an LCRS and 5.1 surround setup
at the same time).
Changing surround mode
The surround mode is set from the PAN/BAL SURROUND
MODE screen:
Use the cursor keys to move the triangle cursor
between
STEREO , LRCS , 5.1 and 6.1 .
Press
ENTER to confirm the selection. A popup mes-
sage appears asking you to press
ENTER again to
change the surround mode, or a cursor key to cancel
the operation.
WARNING
To avoid possible damage to speakers and equipment,
we recommend that you turn off all monitoring equip-
ment when changing the surround mode.
Note that when the 5.1 option is selected, the rear
speakers can be linked as MONO using the on-screen
switch.
Buss assignments When a surround mode is
selected, the 24 busses are used to feed the surround
channels as follows (busses 9 through 16 are used for
surround 2, 17 through 24 are used for surround 3,
and are assigned in the same pattern as 1 through 8):
These assignments cannot be changed.
Assigning channels to surround busses
There are two modes in which the surround busses
can be assigned: pan mode on and pan mode off.
This setting is made by pressing and holding the
SHIFT key together with one of the ASSIGN keys.
Note that this pan mode works in a slightly different
way to the pan mode in stereo setting (“Pan switch”
on page 64). Note especially:
• The Buss Link and Pan preference has no meaning
in surround mode. Channels can always have the
pan mode turned on and off independently.
• There are three surround matrices. These can have
pan mode turned on and off independently for each
channel (
SHIFT + ASSIGN 1 through 8 for the first
matrix,
SHIFT + ASSIGN 9 through 16 for the sec-
ond, and
SHIFT + ASSIGN 17 through 24 for the
third).
