CENTER WIDTH: This setting affects how vocals sound through the
three front speakers. A higher number (up to 7) focuses the vocal
information tightly on the center channel. Lower numbers broaden
the vocal soundstage across the three speakers.
DIMENSION: This setting affects the depth of the surround presentation,
allowing you to “move” the sound toward the front or rear of the room.
The setting of “0” is a neutral default. Setting “F-3” moves the sound
mostly toward the front of the room, while setting “R-3” moves the
sound mostly toward the rear.
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, maintaining 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 full-OSD
menu system. With a Dolby Digital program encoded with Night mode
playing, press the Night Button on the remote. Each press of the button
will cycle through the three settings, with the selected setting being
displayed on the front panel and in the semi-OSD display.
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 activated, 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 154 defaults
to the Logic 7 Music mode for all analog and PCM audio inputs.
Subsequently, 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.
Dolby Digital and DTS digital signals are handled slightly differently. Consult
Table 2 for the alternate surround modes available when one of these digital
signals is detected. For example, you may prefer Dolby Digital Stereo when
a Dolby Digital 5.1 signal is present if only two speakers are connected to
the AVR. By default, the AVR selects the mode encoded in the incoming
bitstream, i.e., Dolby Digital 5.1 in the example.
To change the AVR’s default behavior so that it always selects the alternate
mode when the digital bitstream is present:
1. Select the desired alternate mode when the digital mode is present. In
this case, play a Dolby Digital 5.1 DVD and press the Dolby Surround
Mode Button on the remote repeatedly to select Dolby Digital Stereo
mode.
2. Change the DEFAULT SURR MODE setting in the System Setup menu
to OFF.
Table 2 provides descriptions of all surround modes available on the
AVR 154, along with the incoming bitstreams or signals that the particular
mode may be used with. Feel free to experiment and simply cycle through
all of the available modes at any time; you cannot cause any problems for
the AVR 154 by doing so.
System Settings
The AVR 154 offers several system settings that make the receiver easier
to use rather than directly affecting performance. Access these settings
by pressing the OSD Button and navigating to the SYSTEM SETUP line
of the MASTER MENU. Press the OK Button to display the submenu.
See Figure 66.

VFD FADE TIME OUT: Some people find the brightness of the AVR’s
front-panel display distracting during movies or listening sessions. It’s
possible to dim the front-panel display completely using the Dim function
(see below). This sets the display to remain dark most of the time, lighting
