CHAPTER 5
For 2 channel input sources, you 
can choose from the following modes: 
     STEREO                         
DOLBY PRO LOGIC II              
DOLBY PRO LOGIC IIx            
PARTY                                      
JAZZ CLUB                               
DTS Neo:6                      
SOURCE DIRECT
The mode selection can be made 
from the front panel MODE buttons,    
or from the remote control.
STEREO
This is the conventional two-chan-
nel stereo mode with sound from 
your left and right speakers. The 
TGIV bass management lets you 
use your subwoofer to handle the 
lower frequency range.
We recommend that you try the 
HOLOGRAPHIC IMAGE when 
using stereo sources.
DOLBY PRO LOGIC II and     
DOLBY PRO LOGIC IIx
These modes allows you to enjoy 
many of the benefi ts of Dolby 
Digital (and Dolby Digital EX) from 
your stereo sources.
DOLBY PRO LOGIC II features 
enhanced realism from full range 
stereo surround channels. Use 
this mode to listen to your stereo 
sources in 5.1 surround sound. 
It has two options, Movie and 
Music, which can be set using the 
On Screen Display (OSD) menus.
Surround Modes for 2-Channel Sources
In MOVIE mode, Dolby Surround 
soundtracks are decoded by the 
TGIV into separate channels: left 
and right channels for off-screen 
imaging, a center channel for 
most on-screen dialog, and stereo 
surround channels for ambience 
and special effects. This is the 
mode to use for any surround-en-
coded material.
Try MUSIC mode for all of your 
stereo programs, and adjust these 
extra options to suit your taste: 
  Center Width spreads the 
center channel across the front 
soundstage.
  Panorama wraps the left and 
right channels around you.
  Dimension adjusts the front/
rear balance.
DOLBY PRO LOGIC IIx extends 
the Dolby Pro Logic II technol-
ogy by adding stereo full range 
surround back channels. Use this 
instead of Dolby Pro Logic II if you 
are using the surround back chan-
nels in your system. This also 
has Movie and Music options as 
described above.
PRO LOGIC mode emulates the 
original standard surround mode. 
It can be used for source material 
which is not of optimum quality, 
or if you just feel nostalgic for the 
way things were.
MATRIX mode can be used for 
mono sources, or for FM pro-
grams with poor stereo reception.
PARTY
This extra stereo mode copies the 
front speaker signals to the other 
speakers in your system. This 
mode adds tremendous presence 
to your stereo sources and is 
great for parties and casual listen-
ing alike. The OSD menu can be 
used to select which speakers are 
active in this mode.
JAZZ CLUB
In this DSP mode, the surrounds 
simulate the ambiance caused 
by rear refl ections and effects of 
a small to medium sized venue. 
This is useful for adding surround 
sound effects to stereo sources. 
The ambiance effect can be var-
ied using the OSD MODES menu.
DTS Neo:6
The CINEMA option can produce 
up to six full range, separate 
channels and a subwoofer output 
from stereo matrix surround 
sources. This enhances the play-
back of sources such as surround 
sound video tapes, Laser Discs 
and broadcast TV programs.
The MUSIC option can expand 
normal stereo programs into six 
channels. It does so in a natural 
sounding way, which enhances 
the listening experience.
SOURCE DIRECT
This mode bypasses all DSP, 
Tone, and bass management 
circuits. It is stereo analog only, 
and offers the shortest signal 
path through the TGIV. Only the 
front left and right speakers are 
engaged. Do not use this mode 
for digital-only sources, as it 
only routes the analog audio. To 
prevent damage to your speakers, 
this mode only works if your front 
speakers are set to Large. 
In addition to these modes, and 
those offered for multi-channel sourc-
es, the side-axis speakers will widen 
the front sound stage and fi ll in the 
sound fi eld between the front speak-
ers and the surrounds. Note that the 
side-axis speakers are active in stereo 
as well as multi-channel operation.
The Holographic Image can also 
be selected for any 2 channel or multi-
channel source for enhanced realism 
and depth.
