.
Press the button again to listen to the input
source directly again.

button to tune lower frequency stations and the
right side of the button to tune higher frequency
stations. When a station with a strong signal is
tuned, the TUNED indicator G will illuminate in
the Information Display Û. A brief press of
the button will manually tune to the next fre-
quency increment, while pressing and holding

VMAx indicator A will light, and you will
notice a wider, more spacious field. In order to
obtain maximum benefit, you should be seated
midway between the two loudspeakers, and the
same distance from the speakers as the speakers
are from each other. The speakers must be
placed facing parallel and evenly with each
other so that their baffles are in the same plane.
Press the button again to return to Stereo mode.

In the STEREO mode, a Stereo Indicator F
will illuminate in the Information Display Û
, and stereo reception will be provided when
stations are transmitting stereo signals. In the
MONO mode, the left and right signals from
stereo broadcasts will be mixed together and
repro-duced through all channels. Select MONO
for better reception of weak signals. VMAx will
have no effect in MONO mode.
(
Sleep Button: Press this button to place
the unit in the Sleep mode. Each press of the
button selects the amount of time that will
remain before the unit automatically goes into
the Standby mode, as shown in the Informa-
tion Display 
Û, in the following order:
Ó
Bass Control: Turn this control to modify
the low-frequency output of the left/right chan-
nels by as much as ±10dB. Set this control to a
suitable position for your taste and room
acoustics.
Ô
Treble Control: Turn this control to modify
the high-frequency output of the left/right chan-
nels by as much as ±10dB. Set this control to a
suitable position for your taste and room
acoustics.
Balance Control: Turn this control to
change the relative volume for the front
left/right channels.
Ò
Volume Control: Turn the knob clockwise
to increase volume, counterclockwise to
decrease the volume.
Ú
Volume/Mute Indicator: This indicator
will glow green when the HK 3470 is turned on.
Its position will enable you to judge the relative
volume of the unit even when the speakers are
muted or turned off. When the indicator is point-
ing towards the left, at an “8 o’clock” position,
the volume is low; when it is pointing to the
right, as in a “3 o’clock” position, the volume is
loud. When the unit has been muted, pressing
the Mute button 5, the indicator will flash.
Û
Information Display: This display delivers
messages and status indications to help you
operate the receiver.
Ù
Speaker Selection Indicators: These indi-
cators light as a green LED next to the designa-
tion for each speaker pair to show when they
are active. Press the Speaker 1 6 or Speaker
7 Selectors to activate either pair of speak-
ers. Both sets of speakers may be selected simul-
taneously as long as all speakers are norminally
rated at an impedance of 8 ohms or greater.
However, occasionally the actual impedance will
vary, depending upon the program material.
When the impedance drops too low, the HK
3470 will go into protect mode in order to pre-
vent damage to the equipment. If this should
occur frequently, be sure to select only one set of
speakers at a time until you are able to obtain
speakers with a higher nominal impedance.
ı
Remote Sensor Window: The sensor
behind this window receives infrared signals
from the remote control. Aim the remote at this
area and do not block or cover it unless an
external remote sensor is installed.
