Test Tone; Crossover Frequency - Sony STR DA6400ES Operating Instructions Manual

Tips
• The "LARGE" and "SMALL" settings for each
speaker determine whether the internal sound
processor will cut the bass signal from that
channel.
When the bass is cut from a channel, the bass
redirection circuitry sends the corresponding bass
frequencies to the subwoofer or other "LARGE"
speakers.
However, since bass sound has a certain amount of
directionality, it is best not to cut it, if possible.
Therefore, even when using small speakers, you
can set them to "LARGE" if you want to output the
bass frequencies from that speaker. On the other
hand, if you are using a large speaker, but prefer not
to have bass frequencies output from that speaker,
set it to "SMALL."
If the overall sound level is lower than you prefer,
set all speakers to "LARGE." If there is not enough
bass, you can use the equalizer to boost the bass
levels.
• The surround back speakers will be set to the same
setting as that of the surround speakers.
• When the front speakers are set to "SMALL," the
center, surround, and surround back speakers are
also automatically set to "SMALL."
• If you do not use the subwoofer, the front speakers
are automatically set to "LARGE."
