Remote Control Extension
If the receiver is placed behind a solid or smoked
glass cabinet door, the obstruction may prevent
the remote sensor from receiving commands. In
this event, an optional remote sensor may be
used. Connect the output of the remote sensor
to the Remote IR In jack

AC Power Connections
This unit is equipped with an accessory AC out-
let. It may be used to power accessory devices,
but it should not be used with high-current draw
equipment such as power amplifiers. The total
power draw may not exceed 100W at this out-
let.

This Switched AC Outlet
will receive
power only when the unit is on. This is recom-
mended for devices that have no power switch,
or those with a mechanical power switch that
may be left in the “ON” position.

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 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.
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.

A good starting point for speaker placement is to make
the distance between the two speakers and the distance
between either speaker and the listener identical.

To optimize the sound field, or to suit your lis-
tening room environment, you may find that
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.

Finally, when all connections are complete, plug
the power cord into a nonswitched 230-volt AC
wall outlet. You’re ready to enjoy the HK 3480!
