Analog Output

¦There are two options for analog output: 2-channel and 6-channel.

¦2-channel mode combines the center, left and right surround and subwoofer audio signals to the front left and right speaker outputs.

¦You must set the item ANALOG OUTPUT to 6-CHANNEL when connecting to 6-channel analog output equipment or there will be no output at the center left and right surround and subwoofer speakers.

¦Similarly, you must set the item ANALOG OUTPUT to 2-CHANNEL when connecting to 2-channel analog output equipment or the center, left and right surround and subwoofer channels cannot be reproduced resulting in a movie with no dialog.

¦Use the 1 234 keys to highlight the item ANALOG OUTPUT and use the 34 keys to select an option. Press the OK key to confirm or press the MENU key to save and quit the Setup Menu.

Digital Output

¦Digital signals output through an optical cable or a coaxial cable. They contain all the original audio information, recorded on the disc in a special format. Common formats include PCM, AC-3, DTS and MPEG. Digital signals cannot be reproduced directly to sound and must be first restored to an analog signal (by a decoder), amplified (by a receiver) and used to drive speakers.

¦There are 2 types of digital audio output: bit-stream (BITSTRM) and LPCM. Bit-stream output contains Dolby digital or DTS audio signal and can only be decoded by equipment with Dolby Digital (also known as AC-3 or Dolby 5.1) or DTS audio decoding capabilities. LPCM is the standard output for digital audio signals and can be decoded by most digital decoders.

¦Digital output and analog output do not conflict.

¦Use the 1 234 keys to highlight the item DIGITAL OUTPUT and use the 34 keys to select an option. Press the OK key to confirm or press the MENU key to save and quit the Setup Menu.

Dynamic Range

¦Dynamic range is used to moderate the original loudness of a movie automatically to make it gentler to the ears. When activated, it raises faint sounds and softens loud sounds to suit nighttime viewing.

¦Use the 1 234 keys to highlight the item DYNAMIC RANGE and use the 34 keys to select an option. Press the OK key to confirm or press the MENU key to save and quit the Setup Menu.
