DV29

Speaker set-up
This menu screen allows you to specify the speaker con guration that is connected
either to the analogue ouputs of your DVD player, or to your HDMI receiver when
the HDMI link is carrying multi-channel uncompressed audio. (If you are using
the coaxial or optical audio outputs, set all speakers to ‘Large’ or ‘Present’.) It is
important that this con guration re ects accurately the actual situation, otherwise
audio quality may be severely compromised.
The speakers are indicated as follows:
Front L/R This is the setting for the ‘Front’ speakers (the speakers used for 2-
channel stereo output).
Centre This is the ‘Centre’ speaker setting.
Surround
L/R
This is the setting for the ‘Surround’ speakers (normally next-to or
behind the user).
Subwoofer This is used to indicate whether a subwoofer is connected.
For each speaker, the player can be con gured to send either audio with the full frequency
range of the source material, or with a reduced frequency range. The reduced frequency range
option is used normally when ‘satellite’ speakers are used for the surround channels; these
cannot handle low frequency information. Full frequency speakers are commonly called ‘Large’
speakers, with reduced-range speakers given the name ‘Small’. Low frequency information is re-
routed from ‘small’ speakers to ‘large’ speakers, or to the subwoofer (depending on the speaker
con guration).
NOTES:
1. Any speaker that is not connected should be identi ed by selecting ‘Not Present’ for
that speaker.
2. Although the DV29 is very exible in the speaker con gurations it can handle, some
restrictions have been applied. For example, if no subwoofer is present, then it is not
possible to con gure the Front speakers to be ‘Small’ since there would be nowhere
to redirect the low frequency information.
Stereo+Sub
This setting is relevant to 2-channel source material only (such as CDs). It controls whether the
low frequency information is redirected to the subwoofer, or not. This item can be changed only
if a subwoofer is speci ed as present in the system.
None No redirection of low-frequency information occurs; all the audio is sent to the
Front speakers.
Crossover Low-frequency information is redirected to the subwoofer, with the remaining
(higher-frequency) information sent to the Front speakers.
Duplicate All the audio is sent to the Front speakers. In addition, the low-frequency
information is duplicated to the subwoofer.
Crossover Frequency
This setting de nes the frequency at which bass redirection begins. Frequencies below this level are
redirected from ‘small’ speakers to the Fronts or to the subwoofer; frequencies above this level are not
redirected. The redirection frequency is the same for all the speakers in a system.
The optimum crossover frequency depends on the characteristics of your speaker set-up, and is best
determined by experimentation. We suggest you start at 100Hz.
Delay set-up
The delay set-up menu page allows two different type of delay to be con gured:
those due to speaker positioning and those due to video post-processing.
Speaker positioning
The relative positioning of speakers within a room (particularly a large room)
may mean that sound from some speakers arrives at the listener later than
sound from others. By altering the delay settings for the different speakers,
this difference in arrival time can be reduced or eliminated.
When setting the delay, it should be imagined that the listener is sitting in a
circle of the speakers; the delay indicates the distance of the speaker from the
listener.
Measurement Units
Your DV29 allows you to choose the measurement units that you feel most
comfortable with: metres or feet.
Delays
Delays for the front, centre and surround speakers can be set using the associated sliders. A delay
may be necessary for a speaker set if those speakers are further away from the listener than the
others – specifying the different speaker distances will cause a slight delay to be added to the output
of the closest speakers so that the sound from all the speakers will arrive at the listener at the same
time.
Note that these delay sliders affect only the analogue and the HDMI outputs (although the HDMI
output is affected only when carrying multi-channel uncompressed audio, not otherwise). The
coaxial/optical digital audio outputs are never affected by changes here. If you are using these
digital audio connections between the DV29 and your receiver, set all of the delays to zero.
