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.

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.
