(3–1)x3+15=21. Thus, in this example, the Pro Logic delay should be set at twenty millisec- onds.
NOTE: The DTS, Logic 7, 5CH Stereo, Hall and Theater modes use a fixed, nonadjustable delay time.
The Dolby Digital Mode also includes a separate setting for the center channel delay mode, since the discrete nature of these signals makes the location of the center channel speaker more criti- cal. To calculate the delay for the center channel, measure the distance from the preferred listening position in the center of the room to both the center channel speaker and either the left or right speaker.
If the distances are equal, no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposition the speakers by mov- ing the front left and front right speakers closer to the listening position or the center speaker further away from the listening position.
If repositioning of the speakers is not possible, adjust the center delay time, adding one milli- second of center channel delay for every 30 cm closer to the listening position the center speaker is than the front speakers. For example, if the front left and front right speakers are each 3 m from the listening position and the center chan- nel speaker is 2.4 m away, the delay is figured as 300 cm –240 cm=60 cm, suggesting an optimal center delay of 2 milliseconds.
To set the delay time, follow these steps:
1.To make the delay settings for the Dolby Digital mode (this will include the Center delay setting, and the surround delay for the Pro Logic mode will be set automatically), press the Input Source Selector !on the front or 4on the remote and select any input now that is associat- ed with a digital input and the Dolby Digital sur- round mode (the surround mode associated with each input selected will be indicated by the Surround Mode Indicators ˆin the front panel).
2. Press the Delay button on the remote or front panel. The words S DELAY TIME appear in the Main Information Display X.
3.Press the Set button EÓ.
4.Press the ⁄/¤ buttons Con the remote or the Selector buttons 5on the front panel until the desired rear delay time for the Dolby Digital mode, calculated using the formula for Dolby Digital above (item a.), appears in the display.
5.Press the Set button EÓto enter the setting into the AVR2000’s memory.
6.Press the ⁄/¤ buttons Con the remote once, so that C DELAY TIME appears in the Main Information Display X.
7.Press the Set button EÓ.
8.Press the ⁄/¤ buttons Con the remote until the desired delay time for the center chan- nel appears in the display.
9.Press the Set button EÓto enter the set- ting into the AVR 2000’s memory.
You have now completed the delay time settings for all surround modes and inputs.
Night Mode Settings
The Night mode is a feature of Dolby Digital that uses special processing to preserve the dynamic range and full intelligibility of a movie sound track while reducing the peak level. This prevents abruptly loud transitions from disturbing others, without reducing the sonic impact of a digital source. Note that the Night mode is only avail- able when the Dolby Digital surround mode is selected.
To adjust the Night mode setting press the Input Source Selector !on the front or 4on the remote and select an input that is associated with a digital input and the Dolby Digital sur- round mode.
Next press the Night button Aon the remote. When the button is pressed, the words D-RANGE will appear in the Main Information Display X. Press the ⁄/¤ buttons Cwithin three seconds to select the desired setting:
OFF: When OFF is shown in the display, the Night mode will not function.
MID: When MID is shown in the display, a mild compression will be applied.
MAX: When MAX is shown in the display, a more severe compression algorithm will be applied.
When you want to use the Night mode feature, we recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired.
When any Night mode is selected, the NIGHT Mode Indicator Nwill illuminate. To confirm the selection press the Set button EÓor wait for some seconds until the display returns to the normal mode.
Output Level Adjustment
Output level adjustment is a key part of the con- figuration process for any surround sound prod- uct. It is particularly important for a Dolby Digital receiver such as the AVR 2000, as correct outputs will ensure that you hear sound tracks with the proper directionality and intensity.
NOTE: Listeners are often confused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambiance, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set it is normal for surround speakers to operate only occasionally. Artificially increasing the vol- ume to the rear speakers may destroy the illu- sion of an enveloping sound field that dupli- cates the way you hear sound in a movie the- ater or concert hall.
IMPORTANT NOTE: The output level can be adjusted for each digital and analog surround mode separately. This allows you to compensate for level differences between speakers, that may also vary with the surround mode selected, or to increase or decrease the level of certain speakers intentionally, depending on the surround mode selected.
Before beginning the output level adjustment process, make certain that all speaker connec- tions have been properly made. The system volume should be turned down at first. Finally, make certain that the Balance Control &is set to the center “12 o’clock” position.
To adjust and calibrate the output levels, follow these steps. For accurate calibration, it is a good idea to make these adjustments while seated in your favorite listening position. As the adjust- ment must be made for each surround mode, it is best to select any input associated with Dolby Pro Logic, make the adjustment for that surround mode, then step through all inputs you´re using (and thus through all surround modes associated with the inputs) and repeat the adjustment when any surround mode appears that has not yet been adjusted.
1.Select any input associated with the Dolby Pro Logic surround mode by pressing the Input Source Selector !4until the Pro Logic Surround Mode Indicator ˆon the front and Fin the display light up.
2.Press the Test Tone button 7ıon the remote. The words T-T FL 0dB will appear in the Main Information Display X.
