Adjusting  with  the  main  remote  control  unit  using  the  test  tones  is
only possible in the “Auto” mode and only effective in the STANDARD

again.

• The level of each channel should be adjusted to 75 dB (Cweighted,

slow meter mode) on a sound level meter at the listening position. If
a sound level meter is not available adjust the channels by ear so the
sound levels are the same. Because adjusting the subwoofer level
test tone by ear is difficult, use a well known music selection and
adjust for natural balance.

• Speakers set to “None” in the “Speaker Configuration” settings are

not displayed.

• When “Channel Level” is adjusted, the adjusted values are set for

all  the  surround  modes. To  adjust  the  channel  level  separately  for
the  different  surround  modes,  use  the  operation  see

Setup when using a THX-certified speaker.

:

Only  the  portion  of  the  bass  sound  of  the  various  speakers  output
from  the  subwoofer  that  has  a  frequency  below  the  frequency  set
here is output.
Set this according to the low frequency reproduction capabilities of the
speakers you are using.

:

Specify crossover frequency for each speaker.

• Please set all THX Certified speakers, set the “Speaker Configuration”

for all speakers to “Small”. We recommend using with the crossover
frequency  set  to  “FIXED–THX–”,  but  depending  on  the  speaker,
setting it to a different frequency may improve frequency response
near the crossover frequency.

• The  “Crossover  Frequency”  can  be  set  when  there  are  speakers

that have been set to “Small” at GUI menu “Speaker Configuration”
or when “Subwoofer” is set to “Yes” (

vpage 23).

• At the “Advanced” settings, if the “Subwoofer Setup” (

vpage 24)

setting is set to “LFE–THX–”, GUI menu speakers for which “Speaker
Configuration” is set to “Small” can be set. If set to “LFE+Main”,
the setting can be made regardless of the speaker size.

• For speakers set to “Small”, sound below the crossover frequency

is cut from the sound output. The cut bass sound is output from the
subwoofer or front speakers.

h

Set the speaker to play the optimal THX surround mode.

Set when using a subwoofer compatible with THX Ultra2 standards or
a subwoofer that can be properly played at low range.

Make these settings when “Yes” is selected for the subwoofer in the
“Speaker  Configuration”  settings. This  option  is  not  available  when
“No” is selected (

vpage 23).

If bass sound feels big compensate by lowering volume.

• If the bass sound seems too strong:
 Set “BGC” to “ON”. This activates a filter that gently reduces very

deep  bass  below  55  Hz  to  provide  the  flattest  overall  deep  bass
response. Select “ON” or “OFF” according to how strong you prefer
the deep bass response to be.

• This can be set when the “THX Ultra2 Subwoofer” setting is set to

“Yes”.

Set the distance between the left and right surround back speakers.

• When  two  surround  back  speakers  have  been  set  in  “Speaker

Configuration” (

vpage 23), set the distance of the speakers. This

option is not available when “1spkr” is selected.

• This setting is necessary to achieve the optimum effect in the THX

Surround EX, THX Ultra2 Cinema, THX Music mode and THX Games
mode.
