General AVR Settings
Network Settings: When the AVR is connected to a home
network router using the Network Jack, you may play shared content
stored on a PC or other device connected to the network, and you
may enjoy Internet Radio streams when the network is connected
to the Internet. If you are having difficulty accessing these sources,
check the Network Settings. Highlight the Network Settings line and
press the OK Button to view the Network Settings submenu.
• ID #: This line is informational only, and identifies the AVR
to other devices on your home network and the Internet for
www.radioharmankardon.com.
• Network Settings: If leaving this setting at “Automatic”
does not allow access, press the OK Button to change it to
“Manual” and adjust the other settings below it.
• IP Address, Subnet Mask, Gateway, Primary
DNS, Secondary DNS: Depending on your system, this
information may be set automatically and may change each
time the AVR accesses the network for a new listening session.
Contact your ISP for this information.
• Proxy Address and Proxy Port: Some network security
systems access the Internet using a proxy server. Sometimes
filling in just this information correctly may resolve Internet
access issues.
Volume Units: Select whether volume is displayed in the
conventional decibel scale or on a numeric scale from 0 to 90.
When the decibel scale is used, 0dB is the maximum recommended
volume, with lower volumes displayed as negative values.
Volume Default and Volume Default Level: These two
settings are used together to program the volume level at turn-on.
Turn Volume Default on, and then set the Volume Default Level to
the desired turn-on volume. When the Volume Default setting is left
off, the AVR will play at the last-used volume setting from the previ-
ous listening session.
Unit of Measure: Adjusts the speaker-distance settings for
Manual Speaker Setup. Select between meters and feet.
Language: Select the preferred language for the AVR’s on-screen
menus and displays: English, French, Spanish, German, Italian or
Russian.
HDMI Audio to TV: Determines whether HDMI audio signals
are passed through the HDMI Output to the video display. In normal
operation, leave this setting Off, as audio will be played through the
AVR. To use the TV by itself, without the home theater system, turn
this setting On. Mute the TV’s speakers when using the AVR for audio.
Dolby Volume Calibration: This setting determines the
Dolby Volume Calibration Offset, as described on page 33. Its
default of 0dB is best when the system’s loudspeakers have a
sensitivity rating of 88dB (8 ohms, 1 watt, 1 meter). If your loud-
speakers have a higher sensitivity rating, increase the Dolby Volume
Calibration setting by the difference between your speakers’ sensi-
tivity and 88dB. If your speakers have a lower sensitivity, decrease
the Dolby Volume Calibration setting by the difference between
88dB and your speakers’ sensitivity.
Menu Appearance
Menu Transparency: Select whether video programs will
be visible when the menu system is in use. Select Normal for a fully
transparent background, Medium for partial transparency or Opaque
to block video programs while the menus are on screen.
Volume Status Messages: When the AVR is turned on,
the volume is adjusted or the source is changed, or if a change in
the input signal is detected, a status message will be displayed on
screen. Select how long the message remains visible, from 2 to
10 seconds, with a default of 3 seconds. Select “Off” if you do not
wish to see the status messages.
Menus: The settings in the Surround Modes, Video Modes and
Audio Effects menus only remain in effect during the current listening
session. This setting governs how long these menus remain visible
after the last adjustment: 5, 10 or 30 seconds, 1 minute or 5 min-
utes. Select “No Time-Out” to view the menus indefinitely, but this
setting is not recommended, due to the danger of “burn-in” on
some video displays.
Setup and Slide-In Menus: This setting determines how
long the setup menus (Main Menu, Speaker Setup Menu, Zone 2
Menu, all slide-in menus) remain visible after the last adjustment.
Select a time-out period of 5, 10 or 15 (the default) minutes, or no
time-out, which leaves the menus on screen until manually cleared.
A time-out period avoids the possibility of burn-in damage to plas-
ma or CRT displays.
Screen Saver: Program a time-out period for no activity (with
no menus displayed) before the AVR’s built-in screen saver begins.
Select a period of 5, 10, 20 or 30 minutes or 1 hour, or turn off the
screen saver. A time-out period avoids the possibility of burn-in
damage to plasma or CRT displays.
System Information
Software Version: This line is informational only. From time
to time, Harman Kardon, Inc., may release software upgrades that
improve performance or add features. If you are experiencing diffi-
culties with the AVR, a customer service representative may ask for
the software version of your product to determine whether a later
upgrade is available.
Upgrade Software: If a software upgrade is released for
the AVR 7550HD, installation instructions will be available in the
Product Support section of the Web site or from Harman Kardon
Customer Service. At that time, you may access this submenu to
install the upgrade software.
NOTE: During a system upgrade, do not power off the
AVR or use any of its controls. Doing so could permanently
damage the AVR.
