JBL AVR580 manual

tem will appear. When the SURR BACK line of the SPEAKER SETUP menu (Figure 5) is set to SMALL or LARGE the AVR580 will be configured for 6.1/7.1-channel opera- tion, and additional modes such as Dolby Digital EX and DTS-ES will appear, as they are only available when seven main speakers are present. In addition, some of the modes available in the AVR580 will not appear unless a digital source is selected and is playing the correct bit- stream.

To select the mode that will be used as the initial default for an input, first press the ⁄/ ¤ Buttons n until the on- screen cursor is next to the desired mode’s master category name, such as DOLBY, DTS, DSP(SURR) or VMAx. Next, press the Set Button p to view the sub-menu. Press the ‹/› Buttons o 37 to scroll through the available choices, and then press the ¤ Button n so that the cursor is next to BACK TO MASTER MENU to con- tinue the setup process.

The following few paragraphs detail the instructions needed for modes with multi- ple choices.

On the DOLBY menu (Figure 4), choices include Dolby Digital, Dolby Pro Logic II- Music, Dolby Pro Logic II-Movie, Dolby Pro Logic II-Emulation and Dolby 3 Stereo. The Dolby Digital EX mode is only avail- able when the system is set for 6.1/7.1 operation by configuring the Surround Back speakers to “Small” or “Large” as described on page 25. When a disc is playing that contains a special “flag” sig- nal in the digital audio data stream, the EX mode will be selected automatically. It may also be selected using this menu or through the front panel or remote controls as shown on page 31. A complete explanation of these modes is found on page 34.

When the Dolby Digital mode is selected, there are additional settings available for the Night mode.

The Night mode is a feature of Dolby Digital that uses special processing to preserve the dynamic range and full intel- ligibility of a movie soundtrack while reducing the peak level. This prevents abruptly loud transitions from disturbing others, without reducing the sonic impact of a digital source. The Night mode is only available when specially encoded Dolby Digital signals are played.

To adjust the Night mode setting, make certain that the › cursor is on the NIGHT line of the DOLBY menu. Next, press ‹/› Buttons o 37 to choose between the following settings, as they appear in the on-screen display:

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 compression algorithm will be applied.

We recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired.

The Night mode may also be adjusted directly any time a Dolby Digital source is playing by pressing the Night Mode Button l. When the button is pressed, D-RANGE will appear in the lower third of the video screen and in the Main Information Display ˜. Press the ⁄/¤ Button n within three seconds to select the desired setting.

When all settings for the surround setup have been made, press the ⁄/¤ Buttons n so that the › cursor is next to BACK TO MASTER MENU, and press the Set Button p to return to the MASTER MENU.

On the DTS menu, the choices made with the ‹/› Buttons o 37 on the remote are determined by a combination of the type of program material in use and whether the 5.1- or 6.1/7.1-channel configuration is in use.

When a DTS source is playing, the choice of modes for 7.1 systems will vary according to the type of program source (DTS 5.1, DTS-ES Matrix or DTS-ES Discrete). Press the ‹/› Buttons

o37 to scroll through the choices that are available for your system and the program in use. The DTS Neo:6 Music mode is available with analog stereo

sources and the DTS Neo:6 Cinema mode is available with analog matrix surround- encoded sources to deliver an enhanced 5.1-channel sound field.

When the 5.1 configuration is in use, the AVR will automatically select the 5.1 ver- sion of DTS processing when a DTS data stream is selected. When the 6.1/7.1 mode is selected, the DTS-ES Discrete mode will automatically be activated when a DTS source with the ES Discrete “flag” is in use. When a non-ES DTS disc is in use, you may select the DTS-ES Matrix mode through this menu to create a full eight-speaker surround mode. See page 34 for a complete explanation of the DTS modes.

On the LOGIC 7 menu, the choices made with the ‹/› Buttons o 37 on the remote are determined by whether the 5.1- or 6.1/7.1-channel configuration is in use. In either case, the selection of a Logic 7 mode enables the AVR580’s processor to create fully enveloping, mul- tichannel surround sound from either two-channel stereo- or matrix-encoded programming such as VHS cassettes, laser discs or television broadcasts pro- duced with Dolby surround.

In the 5.1 configuration, you may select the Logic 7/5.1 Music, Cinema or Enhance mode. They work best with two- channel music, surround-encoded pro- grams or standard two-channel program- ming of any type, respectively. For 6.1/7.1 configurations, the Music and Cinema modes may be selected. The Logic 7 modes are not available when either Dolby Digital or DTS digital soundtracks are in use. See page 34 for a complete explanation of the Logic 7 modes.

On the DSP (SURR) menu, the choices made with the ‹/› Buttons

o37 on the remote select from one of the DSP surround modes that are designed for use with two-channel stereo programs to create a variety of sound field presentations. The choices available are Hall 1, Hall 2, Theater, VMAx Near and VMAx Far. The Hall and Theater modes are designed for multichannel installations, while the two VMAx modes are optimized for use in delivering a full surround field when only the front left and front right speakers are installed. See page 34 for a complete explanation of the DSP surround modes.
