Contents Connections Playback Settings Tips Appendix MPEG (Moving Picture Experts Group), MPEG-2, MPEG-4 Speaker impedance These are the names for digital compression format standards used for the encoding of video and audio. Video standards include “MPEG-1 Video”, “MPEG-2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audio standards include “MPEG-1 Audio”, “MPEG-2 Audio”, “MPEG-4 AAC”. This is an AC resistance value, indicated in Ω (ohms). Greater power can be obtained when this value is smaller. Dialogue normalization function WMA (Windows Media Audio) This function operates automatically during playback of Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS or DTS-HD sources.
It automatically corrects the standard signal level for individual program sources. This is audio compression technology developed by Microsoft Corporation. WMA data can be encoded using Windows Media ® Player. To encode WMA files, only use applications authorized by Microsoft Corporation. If you use an unauthorized application, the file may not work properly. Dynamic range The difference between the maximum undistorted sound level and the minimum discernible level above the noise emitted by the device.
Sampling frequency Downmix Sampling involves taking a reading of a sound wave (analog signal) at regular intervals and expressing the height of the wave at each reading in digitized format (producing a digital signal). The number of readings taken in one second is called the “sampling frequency”. The larger the value, the closer the reproduced sound is to the original. This function converts the number of channels of surround audio to a lower number of channels and plays back according to the system’s configuration. Front panel Display Rear panel 246 Remote Index
