NHK channel assignments
The NHK 22.2 settings have been tuned for op-
timized performance with these channel assign-
ments:
►
Engine 1: Set to 22.2 Top Plane.
This will drive all Top speakers except for TpC
(“voice of God”):
►
1: TpFL, 2: TpFC, 3: TpFR
►
4: TpSiL, 5: TpSiR
►
6: TpBL, 7: TpBC, 8: TpBR
►
Engine 2: Set to 22.2 Mid Plane.
This will drive the front and side Mid speakers
plus TpC:
►
1: FLc, 2: FC, 3: FRc
►
4: FL, 5: FR
►
6: SiL, 8: SiR
►
7: TpC
►
Engine 3: Set to 22.2 Bottom Plane.
This will drive all Bottom and Back speakers:
►
1: BtFL, 2: BtFC, 3: BtFR
►
4, 5: N/A
(can be fed carefully to LFE channels)
►
6: BL, 7: BC, 8: BR
Please note that this setup requires three in-
stances of Reverb 8, so you have to use two Sys-
tem 6000 MKII units.
Good results with the NHL system may also be
obtained using “only” 16 reverb channels. Re-
verb 8 has therefore also been tuned for this
two-engine requirement:
►
Engine 1: Set to 22.2 Top Plane.
This will drive all Top speakers except for
TpBC or TpC:
►
1: TpFL, 2: TpFC, 3: TpFR
►
4: TpSiL, 5: TpSiR
►
6: TpBL, 7: TpBC or TpC, 8: TpBR
►
Engine 2: Set to 22.2 Mid Plane.
This will drive the Mid speakers except for FLc
and FRc:
►
1: FL, 2: FC, 3: FR
►
4: SiL, 5: SiR
►
6: BL, 7: BC, 8: BR
►
This leaves some channels without reverb
(FLc, FRc, TpC/TpBC, BtFL, BtFC, BtFR), but
those are also the least needed in order to
generate envelopment.
Rev page – Reverb Setup section
No of Channels
Settings: 5-16, 22.2, 16-32
Use the No of Channels parameter to define the
total number of Reverb channels you will create
using one or multiple instances of Reverb8.
►
With the No of Channels parameter set to
5-16, you can use the Assignment parameter
(right next to it) to assign each Reverb 8 in-
stance to Layer 1 or 2 of a particular topology
(Surround, Row or Column) – see “Topologies:
Surround, Rows, Columns” (page 33).
►
With the No of Channels parameter set to
22.2, you can use the Assignment parameter
to assign each Reverb8 instance to one of the
three planes (Bottom/Mid/Top) – see “NHK
channel assignments” (page 41).
►
With the No of Channels parameter set to 16-
32, you can use the Assignment parameter to
assign each Reverb 8 instance to Layer 1, 2
or 3 of a particular topology (Row or Column).
Assignment
Range: Depending on setting of
No. of Channels parameter
Use the Assignment parameter to assign every
Reverb8 instance to a particular Layer or Plane.
Make sure that you do not set multiple instances
of Reverb8 to the same Layer.
The available settings are:
►
With the No of Channels parameter set to
5-16: Layer 1 Surround, Layer 2 Surround,
Layer 1 Row, Layer 2 Row, Layer 1 Column,
Layer 2 Column.
►
With the No of Channels parameter set to
22.2: Bottom Plane, Mid Plane, Top Plane.
►
With the No of Channels parameter set to 16-
32: Layer 1 Row, Layer 2 Row, Layer 3 Row,
Layer 1 Column, Layer 2 Column, Layer 3 Col-
umn.
Diffuse
Range: -16 to 16
Use the Diffuse parameter to apply more or less
diffusion to the reverb than the algorithm de-
signer intended for the given Decay time. For
optimum performance, the diffusion is automati-
cally adjusted “behind the scenes” whenever
you change decay time. This parameter gives
you added control to vary the diffusion around
this automatic setting.
