14 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.

• 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

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:

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

A will go out.

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.
