D.RNG (Adjusting dynamic range)Choices: MAX/STD/MINPreset position: MAX* This adjustment is effective only when the Dolby Digital isdecoded.MAX: “Dynamic range” is the difference between themaximum level and the minimum level of sounds.Sounds on a movie originally designed for movietheaters feature very wide dynamic range.Dolby Digital technology can bring the original soundtrack into a home audio format with this widedynamic range unchanged.In this position, a source encoded with the DolbyDigital is reproduced in the original sound track’swide dynamic range providing you with powerfulsounds just like in a movie theater.Selecting this position will be even better if you canlisten to a source in a high output level in a roomspecially soundproofed for audio/video enjoyment.STD (Standard):Powerful sounds of extremely wide dynamic rangeare not always suitable for home use. Dependingupon the condition of your listening environment, itmay not be possible to increase the sound outputlevel as high as a movie theater. However, in a levelsuitable for listening to in your room, the low levelparts of source sound often cannot be heard so wellbecause they will be lost among noises in yourenvironment.Dolby Digital technology also made it possible toreduce an original sound track’s dynamic range for ahome audio format by “compressing” the data ofsound.In this position, a source encoded with the DolbyDigital is reproduced in the “compressed” dynamicrange of the source suitable for low level listening.MIN: In this position, dynamic range is more reduced thanin the STD position.Selecting this position will be effective when youmust listen to a source at lower level.ADJUSTMENTS IN THE “SET MENU” MODEThe following ten types of functions maximize the performance of your system and expand your enjoyment for audio listening andvideo watching.1.
