Bass Peak Level
The loudest part of a movie soundtrack is often LFE bass. The Bass Peak
Level Manager “looks ahead” at the bass signal and reduces the risk of
subwoofer/speaker overload by tailoring bass output to match their power
handling capabilities.
Music and Cinema Speaker Configurations
Two independent speaker configurations are provided for greater flexibility
in bass management:
•
Cinema Speaker Configuration is intended for use with movies that
contain LFE information (5.1/6.1-channel program material).
•
Music Speaker Configuration is optional and can be used to tailor
your system for music (and movies that do not contain an LFE track).
These configurations can be assigned separately to each source. Our
unique Auto-LFE option automatically switches speaker configurations
based on the presence or absence of LFE information. This is useful
when using the same player for DVDs and CDs operating into the same
source. DVD movies with LFE will engage the Cinema configuration, while
CDs with no LFE will engage the Music configuration.
Bass Management, Plus!
For each Speaker Configuration, you can select which speakers you have
in your system (or which ones you want to use), as well as their size—
large or small.
The global crossover frequency determines the low-frequency cut-off for
all speakers set to small and the high-frequency cut-off for the subwoofer.
You can also set the subwoofer to Super which will engage your subwoofer,
even if you have the front speakers set to large. This is particularly useful
when listening to 2-channel music with large fronts, where the Super setting
then allows your subwoofer to reproduce all of the glorious deep bass in
your favorite music recordings.
Advanced Settings for Bass Management
Each Speaker Configuration also includes Advanced Settings which offer a
number of fine-tuning capabilities. You can set crossover points independ-
ently for each speaker group, in 5-Hz increments from 25 Hz to 160 Hz, to
better optimize their low-frequency cut-off. You can also independently set
the cut-off frequency for the subwoofer; and unique to the D1, make precision
adjustments to the Phase and Polarity of the subwoofer. This offers greater
flexibility in dealing with room bass anomalies and allows you to achieve a
seamless blend between the subwoofer and the other speakers in your
system, to provide the most accurate and extended bass possible.
In addition, the D1’s Bypass LFE Crossover allows you to recover LFE
information that might otherwise be lost if you choose to use a particularly
low SUB/LFE crossover setting.
Room Resonance Filter
Rooms often have a prominent resonance peak which can make bass
from even the finest subwoofer sound boomy. Using our proprietary low-
frequency test tones, our Room Resonance Filter allows you to identify and
effectively remove this prominent peak and gain a major improvement in
bass detail and definition.
Dipole Surrounds/Rears
Surround and rear settings apply to both speaker configurations. You can
select direct or dipole—which then automatically presets correct listener
position settings for the reverberant soundfield provided by dipole speakers.
You can also reconfigure surround and rear-channel information in a 7.1
system. With 5.1 output, surrounds can be copied to rear speakers. For
a 6-channel music program, you can have surrounds rerouted to the
rears, while for a 5.1 movie program the surround channel will still be
routed to the surround speakers.

Center-Channel Equalization
When you place a center-channel speaker on top of your TV the front of the
TV screen becomes an extension of the speaker baffle, essentially
“changing” its exterior shape. This can reduce dialog intelligibility. The
D1 addresses this problem with its unique Center-Channel Equalization
feature. Just select your TV’s screen size and the D1’s proprietary algorithm
modifies the center-channel’s frequency response curve to provide the
clearest sound possible.
