Large+Sub Pure stereo fed to left and right and extracted bass is
sent to the subwoofer.
Sat+Sub Use this setting if you have ‘Small’ satellite left and right
speakers. Full bass management is used in analogue stereo so
that analogue sources are fed to the DSP where the bass is
filtered off left and right and redirected to the subwoofer.
NOTE: The above three Stereo Mode settings pass the audio
through the DSP. The Large setting can be duplicated for analogue
inputs by pressing Direct to bypass the DSP.
LFE Level: Allows you to adjust the output level of the low frequency
effects channel relative to the other speakers in the system. This
adjustment affects the loudness of movie low frequency effects such as
thunder, explosions, etc.
DTS LFE Gain: DTS soundtracks typically have the LFE track recorded
10dB lower than the main audio tracks. It is therefore necessary to
compensate for this by raising the LFE output level by 10dB. Setting the
DTS LFE gain to
Normal activates this compensation.
Some DTS soundtracks have been recorded with the LFE signal at
the same levels as the main audio and therefore require no gain
compensation. For these disks set the DTS LFE gain to -10dB.
Sub Stereo: Allows you to trim the subwoofer output for stereo
listening. Use this trim setting, with a stereo source, to reduce the
subwoofer output in stereo playback to an acceptable level. The
subwoofer level for stereo music often needs to be set at a lower
level than that for cinema use. This depends on various factors such as
speakers, the types and styles of music to be played and personal taste.
DVD-A Sub Level: External decoder sub level outputs are typically
the same level as the main audio and therefore require no gain
compensation. For these decoders set the DVD-A sub level to
Normal,
the default setting.
Some external decoders may have the sub output 10dB lower than the
main audio outputs. It is therefore necessary to compensate for this by
raising the sub level by 10dB. Setting the DVD-A sub level to +10dB
activates this compensation.
No. of subwoofers: Allows you to set the number of subwoofers
used in the system from 1 to 3. All three subwoofer outputs are active
all the time. This setting compensates the sub output level for the
number of subwoofers in the system.

THX Surr. EX: This can either be set to Auto or Manual and is only
applicable when playing THX Surr. EX encoded material.
Auto The AV8 automatically switches THX to THX Surr. EX when
suitably encoded material is detected (this can be temporarily
overridden by pressing the
THX button on the AV8).
Manual The AV8 will not select THX Surr. EX automatically. It
can however be selected manually by pressing the
THX button.
Boundary Gain Compensation
THX Ultra2 Sub: THX Ultra2 specified subwoofers can effectively
deliver down to 20Hz, which may be problematic in some rooms.
Set to No if the subwoofer being used is not a THX Ultra2 specified
subwoofer, or is not capable of a good response to 20Hz.
Set to Yes If you are using a 20Hz subwoofer or a THX Ultra2
specified subwoofer. When set to Yes, another menu option
appears.
Boundary Gain Compensation: Tailors the subwoofer low
frequency response.
When set to On, this will roll off the very low frequency
information coming from the subwoofer so that any interactions
and reinforcements from nearby boundaries (i.e., walls) can be
compensated for to reduce boom and overblown bass response.
We recommend this setting for smaller rooms.
When set to Off, the subwoofer output from the AV8 will
remain flat to 20Hz.
Advanced Speaker Array: Set this distance to be the separation
between the surround back left and right speakers. This enables the AV8
to distribute the signal to the surround back speakers appropriately to
get the most accurate image for the soundstage.

Exit without saving
If you choose to ‘Exit Setup’ without first saving the changes, then these
new settings will be used by the AV8 until you recall a preset or press
FAV on the remote control, when the last used preset will be recalled.
This is the case even if the AV8 is put into standby or turned off.
1. Press MENU to go to the ‘Setup Menu Index’ at the ‘Save Setup’
point.
2. Press 4 to select ‘Exit Setup’.
3. Press OK when ‘Exit Setup’ is selected to exit system
configuration.
