Why do the HD channels & Digital channels seem quiet, compared to the Analog channels (Ch. 99 and below) when using Digital Audio Output (Optical/Coax)?
*Return to Questions* This has mostly to do with the dynamic range of the Dolby Digital Signals. Read through the next question & its listed links to get a better idea on what this means. What do the Audio Compression / Matrix Stereo settings mean, in the Audio portion of the Main Menu of the 5100? *Return to Questions* This refers to the Dolby Reference levels for Audio output on the DIGITAL Channels only when using ANY ANALOG audio output. These settings DO NOT effect the sound when using the Digital Audio outputs (Optical or Coax) & DO NOT effect the sound on the ANALOG Channels regardless of audio outputs used (Analog or Digital). There was a very good post on the AVSforum.com DCT5100 Topic that explained what each setting meant in the Audio Set-up menu of the DCT5100. I copied it and posted it separately from the forum to this page. Thanks to — hwc — on AVSforum.com for doing the research.
