Distance
: The speaker distance parameters set delay control for the corresponding audio channel. The
delay is to compensate for the audio propagation time difference caused by the placement of speakers.
Speaker distance compensation is not required if the A/V receiver has the capability to adjust channel
delay and compensate for speaker distance differences. However, if your receiver does not have such
functions (most receivers do not offer these functions for their multi-channel analog input), you may
adjust them through the player. Speaker distance delay is only applied if the player is decoding multi-
channel audio. If you use bitstream audio output to your A/V receiver, the bitstream audio is not
adjusted for speaker distance delay.
Since the delay is calculated based on the distance difference from each speaker to the listener’s
position,
it is important to set the distance for the front speakers first
and then the other speakers.
Any time you change the distance of the front speakers, the distance of the other speakers will be
automatically adjusted to maintain the same distance difference.
For example, in the above diagram, measure the distance (in feet) from the primary listening position to
the Front Left or Front Right Speaker. Your Front Right and Left speakers should measure the same
distance. If they do not, please adjust them if possible. Enter the distance of the Front Speakers (1 in
the above picture) into the “Speaker Configuration” menu.
Next, measure the distance (in feet) from center speaker (2) to the listening position. Move the cursor to
highlight the Center speaker in the Channel Delay setup page, and enter the distance (as close as
possible) in feet. Repeat for each speaker in the system (Center, Surround Left, Surround Right,
Surround Back Left, Surround Back Right and Subwoofer) as available. The player will insert
appropriate delay to the center, subwoofer and surround channels to make sure sound waves from
different speakers arrive at the listener at the same time.
Distance between the surround speakers and the listener must be
shorter
than or
equal
to that
between the front speakers and the listener.
In case the channel delay settings cannot match your speaker configuration, please set all distances to
the same and use your receiver/amplifier to set the channel delay.
NOTE
The front, surround and surround back speakers are configured as pairs. Changes to the distance of
one speaker will automatically change the other speaker of the pair.
