Digital Processing Crossover Network
Digital Crossover provides a separate routing system by
splitting the audio signal into separate frequency bands
optimized for each speaker driver. It provides a fine, three-
dimensional sound field that extend each driver’s
performance to the uppermost. With its built-in time
alignment function, this system also adjusts the sound
shifting that occurs when there is a physical offset between
sound drivers. At a digital processing level, it corrects this
offset by delaying the related audio signal.
Although this function is meant for speakers without
crossover network, it can also be used with bi-amped
speakers.
Tip
• This setting can be done while listening to an audio source.
• Press Mode/D (Blue) to switch from the current audio source to
test noises. Pressing Mode/D (Blue) again or the cursor buttons
will stop the test noises and switch back to the original audio
source.
Note
• This setting can only be made when “Speakers Type (Front)” is
set to “Digital Crossover” (➔ page 58).
■ Crossover
` “250Hz”, “320Hz”, “400Hz”, “500Hz, “630Hz”,
“800Hz”, “1000Hz”, “1250Hz”, “1600Hz”,
“2000Hz”, “2500Hz”, “3200Hz”, “4000Hz”,

Output Band for Test
` High + Low
, High, Low:
Select the output for the audio signal.
Tip
• Pressing Mode/D (Blue) button plays band-limited test noises
which center on the specified frequency.
• We recommend choosing a crossover value that creates no
volume difference between “High” and “Low”.
Note
• Refer to your speaker manual when setting without the use of test
noises.
■ Overlap
` No
` Yes
With this setting, a frequency band near the specified
crossover frequency is output by both tweeters and
woofers. Based on the frequency selected for “Crossover”,
the cutoff frequency of the low-pass filter (LPF) will be set
to 1/3 octave up and that of the high-pass filter (HPF) to
1/3 octave down. Example: With a “Crossover” of
“3200Hz”, the cutoff frequency of the woofers’ LPF will
be “4000Hz”, and the tweeters’ HPF will be “2500Hz”.
Tip
• Sounds processed by Digital Processing Crossover Network are
played.
• You can switch from the current audio source to test noises by
pressing Mode/D (Blue).
• In the case of usage of the bi-amped speakers, if there is a
difference between the crossover frequency in the speakers’ built-
in network and the crossover frequency to be set on the AV
receiver, the frequency dip may be caused. Therefore, it is
recommended that this function should be set to “Yes”.
■ High Level, Low Level
` –6.0dB to 0.0dB
to +6.0dB in 0.5 dB steps
With this setting, you can set the volume of tweeters and
woofers.
Tip
• Sounds processed by Digital Processing Crossover Network are
played.
• You can switch from the current audio source to test noises by
pressing Mode/D (Blue).
■ High Phase, Low Phase
` 0
º
` 180º:
With this setting, you can adjust the phase of tweeters and
woofers.
Tip
• Sounds processed by Digital Processing Crossover Network are
played.
• You can switch from the current audio source to test noises by
pressing Mode/D (Blue).
■ High Distance, Low Distance
` 0inch(0.0cm)
to 12inch(30.0cm) in 1 inch(2.5 cm)
steps
With this setting, you can adjust the virtual position of
tweeter and woofer units. Adjusting “High Distance”
virtually shifts woofers behind tweeters. Adjusting “Low
Distance” virtually shifts tweeters behind woofers.
Tip
• Sounds processed by Digital Processing Crossover Network are
played.
• You can switch from the current audio source to test noises by
pressing Mode/D (Blue).
Cutoff frequencies of the woofers’ low-pass filter (LPF)
and the tweeters’ high-pass filter (HPF) are set according
to the frequency specified for “Crossover”.
