Bus Configuration And Operation In Surround Mode; About The Surround Buses; How The Mix Section Will Operate - Yamaha DSP5D Owner's Manual

Bus configuration and operation in surround mode
When any of the three surround modes (3-1ch, 5.1ch, 6.1ch) are selected, the PM5D's bus configuration and operation will
change as follows.

About the surround buses

While a surround mode is selected, MIX buses 1–8 or MIX
buses 9–16 can be used as surround buses. (The choice of
whether to use MIX buses 1–8 or MIX buses 9–16 is made
in the MATRIX/ST function SURR SETUP screen.)
When you switch the surround mode, the following sur-
round channels will be assigned by default to each of the
MIX buses. (You are free to change these assignments
subsequently.)

S

MIX bus 5/13
MIX bus 6/14
MIX bus 7/15
MIX bus 8/16
Note
MIX buses shaded in gray in this table can be used as con-
ventional MIX buses. However in 6.1ch mode, the MIX 8/16
bus will operate only as FIXED type.
For example when the surround mode is 6.1ch and you
have chosen MIX 1–8 to use as the surround buses, the
surround pan signal flow will be as follows.

How the MIX section will operate

When a surround mode is selected, the MIX encoders allo-
cated to surround buses will operate differently than
normal. For example if MIX buses 1–8 are being used as
surround buses, you can use MIX encoders 1–8 of the MIX
section to edit the following parameters.
❏ If the MIX section [MIX SEND] key is on
1 2 3 4
A L ↔ R
Moves the surround pan of the selected channel
between left and right.
B F ↔ R
Moves the surround pan of the selected channel
between front and rear.
C Front divergence (5.1ch and 6.1ch modes
only)
Adjusts the front divergence (the proportion at which a
signal panned to the center will be sent to the front
center bus and to the front LR buses) of the selected
channel. Front divergence (the DIV F parameter) can
be adjusted if 6.1ch mode is being used.
D Rear divergence (6.1ch mode only)
Adjusts the rear divergence (the proportion at which a
signal panned to the rear will be sent to the rear center
bus and to the rear LR buses) of the selected channel.
E LFE (5.1ch and 6.1ch modes only)
Adjusts the send level of the signal sent from the
selected channel to the LFE (Low Frequency Effects)
bus.
Hint
• For details on each of the surround pan parameters, refer to
SURR PARAM screen ( ➥ p.309) in the Reference section.
• If MIX buses 9–16 are being used as surround buses, you
can use MIX encoders 9–16 to perform the above
operations.
