English Digital Sound Field Parameter Descriptions S. DLY (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 milliseconds (The range depends on the signal format.) Description When Dolby Digital signals are decoded: the larger the parameter, the later the surround sound source begins. When a non-Dolby Digital program is decoded: the larger the parameter, the later the surround sound field begins. No surround sound source is produced. Dolby Digital or DTS Input Direct Sound Others The surround sound field is not reproduced. Direct Sound SUSURRROOUUNNDD(L(SLS/R/RSS) ) S Sound Field S Sound Field Level Level S. DELAY S. INIT. DELAY Time S. DELAY Time ROOM SIZE Function This parameter adjusts the apparent size of the surround sound field. The larger the value, the larger the surround sound field becomes. Control Range 0.1 - 2.0 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.
