OPERATION

Now that you have installed your system components, you are ready to begin enjoying your new audio system.

Turning On the HK 3390

After you plug the power cord into an AC outlet and turn on the Main Power Switch on the rear panel, the Power Indicator should light up in amber. This indicates that the HK 3390 is in Standby mode and is ready to be turned on. See Figure 23.

The HK 3390 may be turned on by pressing the Power Switch or any Source Selector on the front panel or the remote. See Figures 23 and 24.

The Power Indicator will turn white to indicate that the HK 3390 is on. If the PROTECT message appears, unplug the receiver from AC power and check all of your wires and connections. Make sure no speaker wires are shorting out by touching each other, and that there are no breaks in the insulation covering any of the speaker wires, interconnects or the power cord. If the PROTECT message still appears when you plug in the HK 3390 and try to turn it on again, bring the receiver to an authorized Harman Kardon service center for assistance.

To turn the receiver off, press the Power Switch on the front panel, or press the Power Off Button on the remote. When the HK 3390 is left unplugged, any settings you have programmed, including system configuration and preset radio stations, will be preserved indefinitely.

Volume Control

The volume may be adjusted either by turning the knob on the front panel (clockwise to increase volume or counterclockwise to decrease volume), or by pressing the Volume Control Buttons on the remote. See Figure 25. The volume is displayed as a negative number of decibels (dB) below the 0dB reference point. Unlike some volume controls on other products, 0dB is the maximum volume for the HK 3390. Although it’s physically possible to turn the volume to a higher level, doing so may damage your hearing and your speakers. For certain more-dynamic audio materials, even 0dB may be too high, allowing for damage to equipment.

The HK 3390 is designed to reproduce audio with a minimum amount of distortion. This clarity may lead you to believe that your hearing and the equipment can handle higher volumes. We urge caution with regard to volume levels.

Mute Function

To temporarily mute all speakers and the headphones, press the

Mute Button on the front panel or remote. See Figure 26. Any recording in progress will not be affected. If the Subwoofer Trigger Outputs are

in use and the Subwoofer Link Switch is on, muting will turn off the subwoofer’s amplifier to conserve energy. The MUTE message will flash

in the display as a reminder. To restore normal audio, either press the Mute Button again, or adjust the volume. Turning off the HK 3390 will also end muting.

Sleep Timer

You may program the HK 3390 to play for up to 90 minutes and then turn off automatically using the sleep timer.

Press the Sleep Button on the front panel or remote, and the time until turn-off will be displayed. Each additional press of the Sleep Button will reduce the time until turn-off by 10 minutes, until the OFF setting is reached, which disables the sleep timer. See Figures 27 and 28.

When the sleep timer has been set, the front-panel display will automatically dim to half-brightness. If you press any button on the remote or front panel, the display will return to full-brightness. The display will dim again several seconds after your last command.

If you press the Sleep Button after the timer has been set, the remaining time until turn-off will be displayed. You may press the Sleep Button to change the time until turn-off. Pressing and holding the Sleep Button will disable the sleep timer, and the SLEEP OFF message will appear.

Tone Controls

You may boost or cut either the treble or the bass frequencies by up to 10dB.

The Bass and Treble Tone Controls may be adjusted using the knobs on the front panel. Remove the front-panel covers if necessary, then gently press the desired control knob until it unlatches and pops out.

Turn the appropriate knob counterclockwise to reduce the levels of the low frequencies (Bass Control) or the high frequencies (Treble Control), and turn it clockwise to increase the levels for the low or high frequencies. See Figure 29.

You may also adjust the balance to compensate for speaker placement or the acoustic characteristics of your listening room. Ideally, the audio should be heard most clearly at a point exactly midway between the left
