■ Liveness (Liveness) This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early reflections decay. 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. Control range: 0 - 10 Dead Source sound Live SOUND FIELD OPTIONS ■ Rev. Time (Reverberation time) This parameter adjusts the amount of time it takes for the dense, subsequent reverberation sound to decay by 60 dB (at 1 kHz). This changes the apparent size of the acoustic environment over an extremely wide range. Set a longer reverberation time for "dead" sources and listening room environments, and a shorter time for "live" sources and listening room environments. Control range: 1.0 - 5.0 sec Reverberation Source sound Early reflections 60 dB 60 dB REV.TIME Sound source REV.TIME Level Level Time Time Short reverberation Long reverberation Small reflected sound Large reflected sound Small value = 1.0 s Large value = 5.0 s Small value = 0 Large value = 10 ■ Dialogue Lift (Dialog lift) This parameter adjusts the height of the front and center channel sounds by assigning some of the front and center channel elements to the presence speakers. The larger the parameter, the higher the position of the front and center channel sound. Choices: 0, 1, 2, 3, 4, 5 ADDITIONAL INFORMATION English 111
