ADVANCED FUNCTIONS
Dolby Surround Settings
In addition to the MODE line, the DOLBY SURROUND submenu includes three settings that are active only when the Dolby Pro Logic II Music mode has been selected.

CENTER WIDTH: This setting affects how vocals sound through the three front speakers. A higher number (up to 7) focuses the vocal infor- mation tightly on the center channel. Lower numbers broaden the vocal soundstage across the three speakers.
DIMENSION: This setting affects the depth of the surround presenta- tion, allowing you to “move” the sound toward the front or rear of the room. The setting of “0” is a neutral default. Setting
PANORAMA: With the Panorama mode turned ON, some of the sound from the front speakers is moved to the surround speakers, creating an enveloping “wraparound” type of effect.
Night Mode
Night mode is available with some Dolby Digital programs, if it has been encoded in the material. It compresses the peak sound levels, maintain- ing the intelligibility of the dialogue and quieter passages, while reducing the loudness of special effects and louder passages to avoid disturbing others. Three levels of compression are available:
OFF: At this setting, there is no compression, as the Night mode is deactivated.
MID: A mild compression is applied.
MAX: More compression is applied.
We suggest that you experiment with the modes to find a setting that meets your needs.
The Night mode may also be adjusted without using the
Upsampling
The last line of the Surround Select menu activates upsampling, only available with the Dolby Pro Logic II Movie, Dolby Pro Logic II Music and Dolby Pro Logic modes. Normally set to OFF, upsampling, when activat- ed, processes digital sources at a higher resolution for improved sound quality. This feature can be useful to eliminate distortion in some low- resolution sources.
Default Modes
During initial use or after a processor reset, the AVR 145 will default to the Logic 7 Music mode for all analog and PCM audio inputs. Subse- quently, when a source input is selected and an analog or PCM signal is received, the AVR will switch to the last surround mode used for that source input/incoming signal combination.
Whenever a multichannel Dolby Digital or DTS signal is detected, the AVR 145 will automatically switch to that mode, unless the DEFAULT SURR MODE setting in the System Setup menu has been changed to OFF. You may observe that other surround modes are available for use with the multi- channel digital bitstreams. If you would prefer the AVR 145 to use one of those alternate modes any time the same digital signal is detected, then select that mode while the multichannel bitstream is present, and then change the DEFAULT SURR MODE setting in the System Setup menu to OFF.
