Dantax LR-7500 manual Dolby Surround, Upsampling

Theater

The Theater mode creates a sound field that resembles the acoustic feeling of a standard live-performance theater.

Hall 1, Hall 2

The two Hall modes create sound fields that resemble a small (Hall 1) and medium-sized (Hall 2) concert hall.

5-Channel Stereo, 7-Channel Stereo

This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the unit has been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music in sit- uations such as a party, it places the same signal at the front-left and surround-left, and front-right and surround- right speakers.

The center channel is fed a summed mono mix of the in- phase material of the left and right channels.

Stereo

This mode turns off all surround processing and presents the pure left- and right-channel presentation of two-chan- nel stereo programs.

PURE STEREO: When Audio input is selected analog, the unit is in a "bypass" mode with no bass management.

DSP STEREO: When DSP Stereo is selected, the signal is digitized and bass management settings are applied.

Dolby Headphone, DH 1, DH 2, DH 3

Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker surround-playback sys- tem. The DH1 mode creates a headphone presentation that resembles a small, well-damped room and is appropriate for use with both movies and music-only recordings. The DH2 mode creates a more acoustically live room particu- larly suited to music listening. The DH3 mode creates a larger room, more like a concert hall or movie theater.

The Bypass mode bypasses any Dolby Headphone pro- cessing.

BACK TO MAIN MENU

The choices on this menu include the selection of the actu- al surround mode, the selection of rear channel post-pro- cessing when the system is configured for 7.1 operation, adjustments to the Night Mode when available with a Dolby Digital soundtrack, the adjustment of special parameters available when either Dolby Pro Logic ll Music or Dolby Pro Logic llx Music is selected as the surround mode and con- trol over digital upsampling, when available.

•Center Width: This setting adjusts the balance of the vocal information in the front sound stage between the center and front left/right speakers. The lower settings spread the center channel sound more broadly into the left and right channel s. A higher number (up to "7") pro- duces a tighter center channel presentation.

•Dimension: This setting alters the perceived depth of the surround field by creating a shallower presentation that appears to move sounds toward the front of the room, or a deeper presentation that appears to move the center of the sound field toward the back of the room. The setting of "O" is a neutral default, with the range of adjustment shown as "R-3" for a deeper, rear-oriented sound.

•Panorama: Switch this setting on or off to add an envelop- ing wraparound presentation the increases the percep- tion of sound along the sides of the room.

•NIGHT

OFF: When OFF is highlighted, the Night mode will not function.

MID: When MID is highlighted, a mild compression will be applied.

MAX: When MAX is highlighted, a more severe compres- sion algorithm will be applied.

•UPSAMPLING

The setting to turn the unit's upsampling feature on or off.
