29OPERATIONNow that you have installed your components and completed abasic configuration, you are ready to begin enjoying your hometheater system.TURNING ON THE AVR 2600Flip the rear-panel Main Power Switch to the “On” position. ThePower Indicator on the front panel will turn amber, indicating thatthe AVR is in Standby mode and is ready to be turned on. TheMain Power Switch is normally left on.There are several ways to turn on the AVR 2600:a) Press the Standby/On Switch on the front panel.b) Using the remote, press the AVR Power On Button or any of theSource Selectors.To turn the receiver off, press either the Standby/On Switch onthe front panel or the AVR Power Off Button on the remote control.Unless the receiver will not be used for an extended period of time,leave the Main Power Switch on. When the Main Power Switch isturned off, any settings you have programmed will be preserved forup to four weeks.IMPORTANT NOTE: If the PROTECT message everappears in the Message Display, turn off the AVR and unplugit. Check all speaker wires for a short. If none is found, bringthe unit to an authorized Harman Kardon service center forinspection and repair before using it again.VOLUME CONTROLAdjust the volume either by turning the knob on the front panel(clockwise to increase volume or counterclockwise to decreasevolume), or by pressing the Volume Control on the remote. Thevolume is displayed as a negative number of decibels (dB) belowthe 0dB reference point.0dB is the maximum recommended volume for the AVR 2600.Although it’s possible to turn the volume to a higher level, doingso may damage your hearing and your speakers. For certain moredynamic audio materials, even 0dB may be too high, allowing fordamage to equipment. Use caution with regard to volume levels.To change the volume level display from the default decibel scaleto a 0-to-90 scale, adjust the Volume Units setting in the SystemSettings menu, as described on page 42.Dolby VolumeThe AVR 2600 implements Dolby Volume processing, which canimprove the audio performance of the system by revealing subtledetails even at normal home-listening volumes.One concern of the typical home theater listener is that volumescan vary widely for different programs played by a source, e.g.,television commercial advertisements are often much louder thanthe main feature. Another is that details heard in the recordingstudio at typically high reference volumes are lost at the lowervolumes used by many listeners.The AVR 2600 uses two Dolby Volume techniques to address theseissues. The Leveler module maintains a consistent listening volumewithin a source, e.g., while watching commercial television or whilelistening to different tracks on a data CD. The Modeler moduleendeavors to re-create the reference presentation that was heardin the recording studio without losing portions of the program atthe typically lower volume levels often used in the home. When theModeler module is active, you may notice details of the performancethat were hidden when the program was played on other equipment.NOTE: The Dolby Volume processor is not used to levelvolume across sources.To adjust the Dolby Volume setting, press the Audio Effects Button.A screen similar to the one shown in Figure 27 will appear. Movethe cursor to highlight the Dolby Volume setting, and each press ofthe OK Button will switch to one of the options in Table 4 below. Thesettings do not refer to the volume level, which is adjusted normallyusing the Volume Control, but rather to the amount of Dolby Volumeprocessing desired.Figure 27 – Adjust Dolby VolumeTable 4 – Dolby Volume SettingsNOTE: Dolby Volume processing is compatible with sourcesrecorded at a sampling rate of 48kHz. High-resolution sources,such as DTS 96/24, will be decoded at 48kHz. DTS 96/24programs will be played in DTS 5.1 mode. To hear DTS 96/24materials in high resolution, turn off Dolby Volume processing.Dolby Volume Calibration OffsetCalibration Offset is a feature of Dolby Volume processing thatallows you to adjust the calibration of the AVR 2600 to optimallymatch your speakers and listening environment. The AVR 2600 iscalibrated with the average speaker sensitivity in mind; however,different speakers may have different sensitivities. Use CalibrationOffset to adjust the calibration of the AVR 2600 according to thetypes of speakers you have.The average home audio speaker sensitivity is 88dB SPL (8 ohms,1 watt, 1 meter). Check the sensitivity specification for your loud-speakers, found in the owner’s manual or on the manufacturer’sWeb site. If your speakers have a sensitivity rating greater than88dB SPL, increase Calibration Offset by the difference betweenSetting EffectOff No Dolby Volume processingLow Only Dolby Volume Modeler module is activeMedium Both Modeler and Leveler modules are active;Leveler module has a value of 3Max Both Modeler and Leveler modules are active;Leveler module has a value of 9
