Operation
Basic Operation
The HK 3470 is simple to operate, and very sim- ilar to stereo receivers you may have used in the past. This section will explain the use of several features that may be new to you.
•Install the two supplied AAA batteries in the remote as shown. Be certain to observe the (+) and (–) polarity indicators shown in the bottom of the battery compartment.
•When using the HK 3470 for the first time, it will be necessary to press the Main Power button 1 on the front panel to turn the unit on. This places the unit in a standby mode, as indicated by the amber color of the Power Indicator 3. Once the unit is in standby, you may begin a listening session by pressing the System Power Control 2 on the front panel or the Main Power On button å on the remote. Note that the Power Indicator 3 will turn red, then green. This will turn the unit on and return it to the input source that was last used. The unit may also be turned on from standby by pressing any of the Source Selector buttons on the front panel 8 9 ! # $ & or remote ç.
To turn the unit off at the end of a listening session simply press the System Power Control 2 on the front panel or the Main Power Off button ∫ on the remote. This places the unit in the Standby mode, and the Power Indicator 3 will turn amber to remind you that the unit is ready for operation when a power command is received from the remote.
When the remote is used to turn the unit “off”, it is actually placing the system in a standby mode, as indicated by the amber color of the Power Indicator 3.
When you will be away from home for an extended period of time it is always a good idea to completely turn the unit off using the front panel Main Power Switch 1.
•To dim the brightness of the front panel dis- play, press the Dimmer button ˙ on the remote. The first press will dim the lights to half normal. A second press will turn the display completely off. Press the Dimmer button ˙ again to restore the display to normal bright- ness.
Source Selection
•To select a source at any time, press any of the Source Selector buttons on the remote ç or front panel 8 9 ! # $ &.
•During a listening session you may wish to adjust the Bass Ó, Treble Ô and Balance
controls to suit your listening tastes.
•Adjust the volume to a comfortable level using the front panel Volume Control Ò or remote Master Volume Up/Down π but- tons. The volume level is displayed by the posi- tion of the Volume Indicator Ú. Think of the Volume Control knob Ò as the face of a clock, with the Volume Indicator Ú indicat- ing the hour. The HK 3470 is playing at the minimum volume level when the Volume Indicator Ú points to 7 o’clock; when the Volume Indicator Ú points to 12 o’clock (straight up), the HK 3470 is playing at the maximum volume level. It is important that you make sure never to exceed this maximum vol- ume level at any time, in order to avoid possi- ble damage to your loudspeakers due to “clip- ping”, a type of distortion that is not audible to the human ear until it is severe enough to per- manently damage most loudspeakers. It is also possible, depending upon the program material, for clipping to occur at volumes below the max- imum volume level.
•To temporarily silence all speaker outputs,
press the Mute button ®5. This will cut the output to all speakers, but it will not affect any recording or dubbing that may be in progress.
When the system is muted, the MUTE indicator will light in the Main Information Display
Û and the Volume/Mute indicator Ú will flash. Press the Mute button ®5 again to return to normal operation.
•For private listening, plug the 1/4" stereo phone plug from a pair of stereo headphones into the front panel Headphone jack 4.
•One or two separate sets of speakers may be connected to the HK 3470. To listen to one of the speaker sets, press the Speaker buttons 67 on the front panel corresponding to the desired speakers. The active speakers will be
indicated by a lit green LED in the Speaker Indicators Ù display. Both sets of speakers may be turned off for private headphone listen- ing.
•To program the HK 3470 for automatic turn- off, press the Sleep button on the front panel ( or remote ©. Each press of the button will increase the time before shutdown in the fol- lowing sequence:
| | | 90 | | 80 | | | 70 | | 60 | | 50 | |
| | | min | | | min | | min | | | min | | | min | |
| | | | | | | | | | | | | | | | |
| | 40 | | | 30 | | | 20 | | | 10 | | | OFF |
| | | min | | | min | | min | | | min | | |
| | | | | | | | | | | |
The sleep time will be displayed in the Main Information Display Û and it will count down until the time has elapsed.
When the programmed time has elapsed, the unit will automatically turn off. Note that the front panel display will dim to one-half bright- ness when the Sleep function is programmed. To cancel the Sleep function, press the Sleep button (© until the Sleep indicator numbers disappear and the Main Information Display shows the current source. Pressing any control button while the Sleep control is activated will momentarily return the Main Information Display to full brightness for increased legibility without interrupting the Sleep function.
To take advantage of Harman Kardon’s exclu- sive VMAx mode, Press the VMAx button ^†. When the VMAx circuits are engaged, patented processing algorithms are used to cre- ate a three-dimensional sound space with the illusion of “phantom” speakers at center and surround positions. This spacious sound will simulate a surround-sound presentation with- out the need to add additional speakers. To return to standard stereo listening, press the VMAx button ^† again and note that the VMAx Mode Indicator A will go out.
Tuner Operation
The HK 3470’s tuner is capable of tuning AM, FM and FM Stereo broadcast stations. Stations may be tuned manually, or they may be stored as favorite station presets and recalled from a 30-position memory.
Station Selection
1.Press the AM/FM & buttons on the front panel or on the remote ç to select the tuner as an input.
2.Press these buttons again at any time to switch between AM and FM.
