SPEAKER CONFIGURATION

Front L/R
Centre
Surround L/R
Subwoofer
Stereo+Sub
Crossover Freq
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 DV27A 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.

DELAY SETUP

Measurement Unit
Front
Centre
Surround
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 Your DV27A 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.
