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

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:
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
