tightly on the center channel. Lower numbers broaden the vocal sound-
stage. Use the

Buttons to adjust.
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
toward the front of the room, while setting “R-3” moves the sound
toward the rear. Use the
‹

Buttons to adjust.
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” effect. Each press of the OK Button toggles
the setting on or off.
Night Mode
Night mode is available with Dolby Digital programs, if it has been encod-
ed 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.
Night Mode is accessed from the Audio Effects menu. See page 45.
NOTE: To access 6.1- and 7.1-channel modes, the surround
back channels must be enabled as explained in the Manual
Setup section. Do not enable these channels if you don’t have
surround back speakers in your system.
Manual Setup
The AVR 3550HD is flexible and may be configured for most speakers,
and to compensate for the acoustic characteristics of your room.
The EzSet/EQ process automatically detects the capabilities of each
speaker, and optimizes the AVR 3550HD’s performance. If you are
unable to run EzSet/EQ calibration, or if you wish to make further
adjustments, use the Manual Setup on-screen menus.
Before beginning, place your loudspeakers as explained in the Speaker
Placement section, and connect them to the AVR. Consult the owner’s
guide for the speakers or the manufacturer’s Web site for the frequency
range specification. Although you may set the output levels “by ear,” an
SPL (sound-pressure level) meter purchased at a local electronics store
will provide greater accuracy.
Record your configuration settings in Tables A3 through A11 in the appendix
for easy re-entry after a system reset, or if the AVR’s Master Power
Switch is turned off or the unit is unplugged for more than four weeks.
NOTE: When using the AVR’s Speaker Setup menus, select a
video output resolution of 720p or higher to view graphics that
simplify configuration.
Step One – Determine Speaker Crossover
Without using the EzSet/EQ process, the AVR 3550HD can’t detect
how many speakers you’ve connected to it; nor can it determine their
capabilities. Consult the speaker’s technical specifications and locate
the frequency response, usually given as a range, e.g., 100Hz – 20kHz
(±3dB). Write down the lowest frequency that each of your main
speakers is capable of playing (100Hz in the example) as the crossover
in Table A3 in the appendix. This is not the same as the crossover
frequency listed in the speaker’s specifications. For the subwoofer, write
down the transducer size.
The receiver’s bass management determines which speakers will be
used to play back the low-frequency (bass) portion of the source program.
Sending the lowest notes to small satellite speakers won’t sound right,
and may even damage the speaker. The highest notes may not be
heard at all through the subwoofer.
With proper bass management, the AVR 3550HD divides the source
signal at a crossover point. All information above the crossover point
is played through the satellite speaker, and all information below the
crossover point is played through the subwoofer. Each loudspeaker in
your system performs at its best, delivering an enjoyable sound experience.
Step Two – Measure Speaker Distances
Ideally, all of your speakers would be placed in a circle, with the listening
position at the center. However, you may have had to place some
speakers a little further away from the listening position than others.
Sounds that are supposed to arrive simultaneously from different speakers
may blur due to different arrival times.
Use the AVR’s delay adjustment to compensate for real-world speaker
placements.
Measure the distance from each speaker to the listening position, and
write it down in Table A4 in the appendix. Even if all of your speakers
are the same distance from the listening position, enter your speaker
distances as described in Step Three.
Step Three – Manual Setup Menu
Now you are ready to program the receiver. Sit in the usual listening
position and make the room as quiet as possible.
With the receiver and video display turned on, press the AVR Settings
Button to display the menu system. Use the
¤
Button to move the
cursor to the Speaker Setup line, and press the OK Button to display
the Speaker Setup menu. See Figure 51.
If you have run the EzSet/EQ process, the results were saved. Adjust
the EzSet/EQ On/Off setting in the Audio Effects menu to activate or
deactivate the results (see page 45). To tweak the EzSet/EQ results, or
to configure the AVR from scratch, select Manual Setup. The screen
shown in Figure 66 will appear.
