ARROW button or select the Exit option. You can also move on to configure the next speaker by
selecting the Next Speaker option.
The following speaker parameters can be configured:
1. Size: The following speaker size parameters control bass filtering for the speakers.
Large – All audio content is passed to the appropriate speaker.
Small – All audio content, except for bass frequencies, is passed to the appropriate speaker.
The purpose is to reduce possible distortion. If a subwoofer is available, bass frequencies are
re-directed to the subwoofer, otherwise, they are discarded. The bass frequency upper limit is
set by the Crossover Frequency selection in the Setup Menu (see page 48 for details).
Off – Speaker for the corresponding position does not exist. Audio for the missing speaker is
redirected to other speakers or discarded if redirection is not possible.
On (for Subwoofer only) – Specifies that a subwoofer is available.
NOTE
The Size for Front, Surround and Surround Back speakers is configured in pairs. Changes to
the size of one speaker will automatically change the other of the pair.
2. 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.
A typical 7.1-channel speaker layout and their speaker distance measurements are displayed as
