Yamaha DSP-AX2 LIVENESS, ROOM SIZE, P. ROOM SIZE, S. DELAY (Surround Delay), S. ROOM SIZE (Surround Room Size), S. INIT. DLY (Surround Initial Delay)

	DSP Parameter
ROOM SIZE
[P. ROOM SIZE for the presence sound field]	Control Range 0.1 – 2.0

Function .............. This parameter adjusts the apparent size of the surround sound field. The larger the value, the larger the surround sound

field becomes.

Description ......... As the sound is repeatedly reflected around a room, the larger the hall is, the longer the time between the original

reflected sound and the subsequent reflections. By controlling the time between the reflected sounds, you can change the apparent size of the virtual venue. Changing this parameter from one to two, doubles the apparent length of the room.

LIVENESSControl Range 0 – 10

Function .............. This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early reflections

decay.

Description ......... The early reflections of a sound source decay much faster in a room with acoustically absorbent wall surfaces than in

one which has highly reflective surfaces. A room with acoustically absorbent surfaces is referred to as “dead,” while a room with highly reflective surfaces is referred to as “live.” The LIVENESS parameter lets you adjust the early reflection decay rate, and thus the “liveness” of the room.

S. DELAY (Surround Delay)		Control Range 0 – 49 msec (The range depends on the signal format.)
Function ..............	This parameter adjusts the delay between the direct sound and the first reflection in the surround sound field.
S. INIT. DLY (Surround Initial Delay)		Control Range 1 – 49 msec
Function ..............	This parameter adjusts the delay between the direct sound and the first reflection on the surround side of the sound
	field. You can only adjust this parameter when at least two front channels and two rear channels are used.
S. ROOM SIZE (Surround Room Size)		Control Range 0.1 – 2.0
Function ..............	This parameter adjusts the apparent size of the surround sound field.
