■ Preserve THX Settings
`Yes
`No
If this setting is set to “Yes”, Dynamic EQ and
Dynamic Volume have no effect in THX listening
mode.
Note
• This setting is fixed at “Yes” if “Loudness Plus” is set to
“On”.
THX Loudness Plus
THX Loudness Plus is a new volume control
technology featured in THX Ultra2 Plus™ and THX
Select2 Plus™ Certified receivers. With THX
Loudness Plus, home theater audiences can now
experience the rich details in a surround mix at any
volume level. A consequence of turning the volume
below Reference Level is that certain sound elements
can be lost or perceived differently by the listener.
THX Loudness Plus compensates for the tonal and
spatial shifts that occur when the volume is reduced
by intelligently adjusting ambient surround channel
levels and frequency response. This enables users
experience the true impact of soundtracks regardless
of the volume setting. THX Loudness Plus is
automatically applied when listening in any THX
listening mode. The new THX Cinema, THX Music,
and THX Games modes are tailored to apply the
proper THX Loudness Plus settings for each type of
content.
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 65).

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

`180°:
With this setting, you can adjust the phase of tweeters
and woofers.
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”.
