Operation

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

Turning On the HK 3485

After you plug the power cord into an AC outlet, the Power Indicator should light up in amber. This indicates that the HK 3485 is in Standby mode and is ready to be turned on. See Figure 23.

The HK 3485 may be turned on by pressing the Power Switch on the front panel or the remote. See Figure 24.

The Power Indicator will turn red briefly, and then blue to indicate that the HK 3485 is on. If it remains red, then 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, inter- connects or the power cord. If the Power Indicator remains red when you plug in the HK 3485 and try to turn it on again, then 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 3485 is left unplugged, any settings you have programmed, including system configuration and preset radio stations, will be preserved indefinitely.

Sleep Timer

You may program the HK 3485 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 25 and 26.

When the sleep timer has been set, the front-panel display will automati- cally 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.

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 27. 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 3485. 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.

Remember that the HK 3485 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 28. Any recording in progress will not be affected. 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 3485 will also end muting.

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 by turning the knobs on the front panel. Turn either knob counterclockwise to reduce the levels of the low frequencies (Bass Control) or the high frequencies (Treble Control), and turn either knob 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 and right speakers, unless the artist has mixed the recording in a way that pans sounds to one side or the other. If your speakers are not placed the same distance from the listening position, or if your room has other unusual characteristics, turn the Balance Control knob on the front panel counterclockwise to move the sound toward the left speaker or clockwise to move the sound toward the right speaker. See Figure 30.
