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.

AutoThe 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 aTHX Ultra2 specified	English
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.
