the button will manually tune to the next fre-
quency increment, while pressing and holding
the button for a longer period (>0.5 sec) will
step quickly through the frequencies. As soon as

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.

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.

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
2 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.
