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 surround channels will be assigned by default to each of the MIX buses. (You are free to change these assignments subsequently.) Surround mode MIX bus MIX bus 1/9 3-1ch MIX bus 2/10 MIX bus 3/11 MIX bus 4/12 MIX bus 5/13 C (Center) S (Surround) MIX bus 6/14 MIX bus 7/15 MIX bus 8/16 5.1ch 6.1ch L (Front L) R (Front R) Ls (Rear L) Rs (Rear R) C (Center) LFE Bs (Subwoofer) (Rear center) LFE (Subwoofer) Note MIX buses shaded in gray in this table can be used as conventional 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. Input channel 1 Input channel 2 How the MIX section will operate When a surround mode is selected, the MIX encoders allocated 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 12345 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.
