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 available when the Dolby Digital surround mode is selected.
To adjust the Night mode setting from the menu press the OSD Button LE so that the MASTER menu appears. Then press the ¤ button EF to access the SURROUND SETUP and press the Set Button FQ to select the SURROUND SETUP menu. Press Set FQ to select the DOLBY SURR SETUP menu (see fig. 15).
To adjust the Night mode setting, make certain that the › cursor is on the NIGHT line of the DOLBY menu. Next, press ‹/› Buttons EF to choose between the following settings.
OFF: When OFF is highlighted, the Night mode will not function.
MID: When MID is in the highlighted video, a mild compression will be applied.
MAX: When MAX is in the highlighted video, 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.
Note that the Night mode may be adjusted directly any time that Dolby Digital surround mode is selected by pressing the Night button B. When the button is pressed, the words D-RANGEfollowed by the current setting (MID, MAX, OFF) will appear in the lower third of the video screen and in the Main Information Display ˜. Press the ⁄/¤ but- tons EF within five seconds to select the desired setting, then press the Set Button FQ to confirm the setting.
When all settings on the DOLBY SURROUND menu have been competed, press the ⁄/¤ Navigation Button EF until the cursor is next to BACK TO SURROUND SETUP and press the Set Button FQ. You may then make any additional changes to the available options from that screen, or use ⁄/¤ Navigation Button EF to move the cursor to the BACK TO SURROUND CONFIG menu and press the Set Button FQ again to back up one menu.
At the main SURROUND SETUP menu, you may change the SOURCE to make adjustments to another input, or when all input sources have been configured, use ⁄/¤ Navigation Button EF to move the cursor to the BACK TO MASTER MENU and press the Set Button FQ to return to the main menu so that you may move to the next step in configuring your AVR 645.
Using EzSet/EQ
The AVR uses Harman Kardon’s EzSet/EQ tech- nology to automatically configure your system to deliver the best possible performance based on your specific speaker selection, where the speak- ers are placed in the room and the acoustic influ- ences in your listening room. By using a series of test signals and the processing power of the Texas Instruments DA 610 digital signal proces- sor, EzSet/EQ eliminates the need for manual adjustment of speaker “size”, crossover, delay and output level settings while it adds the power of a multi-band parametric equalizer to smooth out the frequency settings for optimal sound reproduction.
In addition to making system setup quick and easy, EzSet/EQ is more precise than manual settings. With EzSet/EQ you are able to calibrate your system in a fraction of the time it would take to enter the settings manually, and with results that rival those achieved with expensive test equipment and time consuming procedures. The end result is a system calibration profile that enables your new receiver to deliver the best possible sound no matter what type of speakers you have or what the dimensions of your listening room are.
We recommend that you take advantage of the precision of EzSet/EQ to calibrate your system, but if desired you may also make any of the configuration settings manually, or trim the settings provided by EzSet/EQ by following the instructions on pages 32-35.
Before starting the EzSet/EQ process, make cer- tain that you have connected all speakers for your system and that you have both the EzSet/EQ microphone and the extender rod handy. If you have a standard camera tripod, attach the exten- der rod to the tripod, and then screw the micro- phone to the top of the rod. Place the tripod at your primary listening position, at least one meter from the nearest speaker and adjust it so that microphone is at least one meter above ear level. If you do not have a tripod, simply screw the extender rod into the bottom of the EzSet/EQ microphone.
Next, plug the microphone into the EzSet/EQ Microphone Jack ˘ located behind the Front Panel Control Door. The microphone cable is approximately 6 meters long, which should accommodate most listening room situations. If required, you may use an optional extension cable, available at most electronics stores, for use in larger rooms. However, we recommend that you make every effort to avoid using extension cords for the microphone cable as they may adversely affect the test results.
Finally, before going further, make certain that the program volume is at -35dB. If there is a volume or “level” control on your subwoofer, make certain that it is set to at least the mid- point, if not a bit higher
You are now ready to start the EzSet/EQ process by following these steps:
Step 1. Navigate to the EZSET/EQ MODE menu (Fig. 17a) by first pressing the OSD Button L on the remote. Press the ¤ Navigation Button E until the ➔ cursor is pointing to EZSET/EQ in the MASTER MENU. Press the Set Button F to bring the menu to the screen.
