This menu screen allows you to specify the speaker 
configuration 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 configuration 
accurately reflects 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 configured 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 configuration).
NOTE:
1.  Any speaker that is not connected should be identified 
by selecting ‘Not Present’ for that speaker.
2.  Although the DV89 is very flexible in the speaker 
configurations it can handle, some restrictions have 
been applied. For example, if no subwoofer is present, 
then it is not possible to configure 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 defines 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.

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.
