dition of the extra Panning Modes and Distance parameters listed below.
Panning Modes are selected using the PMOD control, and Distance pa-
rameters are selected from the ROOM page.
AMPL: This function provides standard amplitude panning with sine/cosine char-
acteristics. If the source is placed exactly between two adjacent loudspeak-
ers, the amplitudes of each are attenuated by 3 dB. Front LCR, back LR,
and front/back are separately adjustable. If the joystick is utilized, front
LCR and back LR are coupled. Divergence is also available.
Note: AMPL is the only Panning Mode in which the left surround/right surround
(LsRs) panning function is available for the 5.1 panner.
HRTF: (Head-Related Transfer Function) This function provides a newly devel-
oped, head-related left/right panning with frequency-depending amplitude
and delay characteristics. Sources can be placed beyond the arc of the front
stereo loudspeakers' base. In use, the Sweet Spot is more critical. Front
LCR and back LR are always coupled. Front/back control is also available,
but with conventional amplitude panning characteristics applied.
SPHR: (Sphere) This function provides head-related left/right panning according
to the transfer characteristics of the "Sphere Microphone" proposed by
Theile. Front LCR and back LR are always coupled. Front/back control is
available, but with conventional amplitude panning characteristics applied.
ORTF: This function provides head-related left/right panning according to the
transfer characteristics of the "ORTF" format stereo microphone layout
(two cardioid microphones, spaced 18 cm at a 110° angle). It combines an-
gle-depending amplitude panning and delay characteristics. Front LCR and
back LR are always coupled. Front/back control is available, but with con-
ventional amplitude panning characteristics applied.
AB: This function provides left/right panning based on delay differences only,
according to the "AB" microphone layout (two omnidirectional micro-
phones, spaced 0.5 m). Front LCR and back LR are always coupled.
Front/back control is available, but with conventional amplitude panning
characteristics applied.
AMBI: (Ambience) This function scales the amplitudes of the automatically gen-
erated echoes from 0% (no effect) over 10% (most natural effect, factory
preset) up to 100% (full effect, echoes exaggerated). If the operator only
wants to place sounds at distinct distances from the listener without adding
coloration, the preset should be left unchanged.
DIST: (Distance) This function adjusts the apparent distance between the sound
source and the listener, if the front/back and left/right control knobs (or the
joystick) are set to a maximum position. By adjusting these parameters, the
sound can be moved, for example, from the extreme left front to the ex-
treme right rear.
ABSN: (Absorption) This function simulates frequency-depending room absorp-
tion caused by walls or obstacles. It can be adjusted from 0% (cold hall, no
absorption) up to 100% (anechoic room; full sound absorption).
SIZE: (Room Size) This function scales the room size. The maximum achievable
distance effect is determined herewith. Normally set to maximum (100%,
largest room available).
