INTRODUCTION PREPARATION BASIC OPERATION SOUND FIELD PROGRAM PARAMETER EDITING I LIVENESS Function: This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early reflections decay. Control range: 0 - 10 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. Sound source Live Level Level Level Dead Time Small reflected sound Time Time Large reflected sound Sound source Small value = 0 Large value = 10 I S.DELAY (surround delay) Function: This parameter adjusts the delay between the direct sound and the first reflection in the surround sound field. Control range: 0 - 49 msec (The range depends on the signal format.) I S.INIT.DLY (surround initial delay) 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. Control range: 1 - 49 msec I S.ROOM SIZE (surround room size) Function: This parameter adjusts the apparent size of the surround sound field. Control range: 0.1 - 2.0 I S.LIVENESS (surround liveness) Function: This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field. Control range: 0 - 10 ADVANCED OPERATION ADDITIONAL INFORMATION APPENDIX English 63
