ROTEL RSP985 - Handbuch (Seite 23)

Subwoofer Setup Menu
This menu, also reached from the MAIN screen,
allows you to optimize the RSP-985 for your
particular subwoofer. The settings in this menu
may be considered to be “advanced” and need
not be adjusted unless specifically desired.
SW LIMITER: The wide dynamic range and
impressive bass effects of today’s source
material can overload a subwoofer. This set-
ting allows you to limit the level of the signal
sent to the subwoofer. Go to the limiter menu
by highlighting the SW LIMITER line and press-
ing ENTER. An instruction menu appears and
a low frequency noise signal is sent to the
subwoofer (or LARGE speakers if no subwoofer
is present). Adjust the noise level with the VOL
buttons until you just begin to hear distortion
from the speakers. Press the ENTER button to
set the limiter at this level. Press BACK to re-
turn.
STEREO/P/L SW: This setting allows you to
override the standard bass management in
STEREO, PRO LOGIC, and DSP MUSIC modes
when LARGE front speakers are selected. Select
YES to have a subwoofer active with LARGE
front speakers in these modes. Select NO if
you don’t have a subwoofer. Select NORMAL
for the standard automatic bass management
in all modes.
LFE MIX LEVEL: This setting determines the
relative signal level of the LFE (Low Frequency
Extension) channel (the .1 channel) relative to
the five full-range channels. It is factory set ac-
cording to the standards of Dolby Labs, DTS
Technology, and THX Lucasfilm. The adjustment
may be varied for each surround mode ac-
cording to personal taste, if desired.
The LFE content of DTS encoded movies is mixed
differently than DTS encoded music. For DTS
movies, the LFE MIX LEVEL should be set to
10dB for correct THX playback. For DTS music,
the level should be set to 0db. THX should not
be activated for music playback. For Dolby
Digital movies, the LFE MIX LEVEL should be
set to 10db for proper playback in DOLBY
DIGITAL and THX modes.
Once you have completed the subwoofer
settings for all of your speakers, return to the
MAIN menu by pressing the BACK button.
Factory Default Menu
The final menu that can be reached from the
SYSTEM SETUP screen is the FACTORY DE-
FAULT menu, which resets all system configu-
ration settings to the factory supplied settings.
NOTE : Resetting to factory default settings will
erase all stored settings including delay set-
tings, speaker settings, balance settings, in-
put settings and more. You will lose ALL system
configuration settings. Be certain that you wish
to do so before resetting the factory defaults.
To reset the factory defaults, press the ENTER
button. This will take you to a confirmation
screen where you will have a chance to con-
firm your decision by pressing ENTER a sec-
ond time.
To return to the SYSTEM SETUP screen with-
out resetting the factory defaults, press the BACK
button.
