Audio and Speaker Connections
After unpacking the unit and placing it on a
solid surface capable of supporting its weight,
you will need to make the connections to your
audio and video equipment. These steps need to
be done only when the receiver is first installed
or when a change is made to the input source
equipment.

NOTE: While most speaker manufacturers
adhere to an industry convention of using black
terminals for negative and red ones for positive,
some manufacturers may vary from this configu-
ration. To assure proper phase, and optimal per-
formance, consult the identification plate on
your speaker, or the speaker’s manual to verify
polarity.
If you do not know the polarity of your speaker,
assure that both speakers are connected with
the same polarity, i.e. speaker wires or terminals

Speaker Placement
For optimal listening enjoyment, and for sound-
field reproduction that best re-creates the origi-
nal recording, it is good practice to place the
speakers so that they form a triangle with the
speakers at the front of the room, and the pre-
ferred listening spot at the third point of the tri-
angle. The distance between each speaker and
the listener should be identical.

speakers at the front of the room, and the pre-
ferred listening spot at the third point of the tri-
angle. The distance between each speaker and

For example, if the speakers are 2,5 meters from
one another, each of the speakers should opti-
mally be placed so that they are also 2,5 meters
from the listener. It is also desirable to place
speakers so that their tweeters, or highfrequency
drivers, are aimed at ear height when you are
seated in the listening position.

To optimize the sound field, or to suit your lis-

some experimentation is required to find the
correct location. Ideally, pans from left to right
across the front of the room should sound
smooth, and instruments should appear to be
coming from the proper location within an
orchestra.

The placement of subwoofers should be done as
suggested in the manufacturer’s instructions. In
general, subwoofers often produce best results
when they are placed in the corner of a room,
along the same wall as the speakers, but optimal
placement will vary widely depending on room
size, the subwoofer type and the placement of
rugs and furniture in a room. It may be helpful
to temporarily position the subwoofer in the
usual listening position, then walk around the
room while program material is playing until the
bass reproduction sounds best to your ears. That
location is likely to be the optimum position for
the subwoofer.

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

• Adjust the volume to a comfortable level using
the front panel Volume Control Ò or remote
Master Volume Up/Down π buttons. The vol-
ume level is displayed by the position of the
Volume Indicator Ú. Think of the Volume
Control knob Ò as the face of a clock, with the
Volume Indicator Ú indicating the hour. The
HK 3370 is playing at the minimum volume level
when the Volume Indicator Ú points to 7
o’clock; when the Volume Indicator Ú points
to 5 PM, the HK 3370 is playing at the maximum
volume level. It is important that you make sure
never to exceed this maximum volume level at
any time, in order to avoid possible damage to
your loudspeakers due to “clipping”, a type of
distortion that is not audible to the human ear
until it is severe enough to permanently damage
most loudspeakers. It is also possible, depending
upon the program material, for clipping to occur
at volumes below the maximum volume level.
