This menu screen allows you to specify the speaker
conguration that is connected to the analogue ouputs of
your DVD player. (Note that these settings do not affect the
digital output in any way.) It is important that this conguration
accurately reects 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 congured 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 conguration).
NOTE:
1. Any speaker that is not connected should be identied
by selecting ‘Not Present’ for that speaker.
2. Although the DV89 is very exible in the speaker
congurations it can handle, some restrictions have
been applied. For example, if no subwoofer is present,
then it is not possible to congure 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.
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 denes 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 optimum crossover frequency depends on the
characteristics of your speaker set-up, and is best determined
by experimentation.
Delay setup

Measurement Unit Metres
Front |--------------------- 0m
Centre |--------------------- 0m
Surround |--------------------- 0m
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 DV89 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.
