OPERATION
Figure 30 – Balance Control
The Balance Control reduces the level of the speaker opposite the
pointer. For example, turning the knob from the midpoint toward “R”
reduces the level of the left speaker, leaving the right speaker unaffected.
If two pairs of speakers are connected to the HK 3485, then both will
be affected.
Headphones
Plug the 1/4" plug on a pair of headphones into the headphone jack on
the front of the receiver for private listening. See Figure 31.

Speaker 1/2
The HK 3485 may be used with up to two pairs of speakers for addi-
tional sound power in the main listening room, or if you wish to place
the second pair of speakers in another room, or even outdoors (when
you select weather-resistant loudspeakers). Select each pair of speakers
by pressing its associated button on either the front panel or remote.
See Figure 32.
Figure 32 – Speaker 1/2 Buttons
Press the button a second time to deactivate that pair of speakers. You
may activate both speaker pairs simultaneously, or deactivate both pairs
for private listening through the headphones.
Source Selection
Select a source device connected to the HK 3485 for playback by
pressing its associated button on the front panel or remote control.
See Figure 33.
Figure 33 – Source Selectors
To enjoy video sources, make sure to connect the device’s composite
video output to the correct Video Input on the HK 3485. In addition,
connect the HK 3485’s Video Monitor Output to an input on your televi-
sion or video display.
NOTES:
• The HK 3485 is not an audio/video surround sound receiver.
It is only capable of playing source programs in one- or two-
channel formats, and any information encoded in additional
channels will be lost. The HK 3485 is not equipped with digital
audio inputs, and cannot decode digital surround sound programs.
If you have connected the analog audio and composite video
outputs of a DVD player to the HK 3485, remember to select
two-channel audio in the DVD player and disc menus.
• The HK 3485 does not switch the last-selected video source
when an audio-only source, such as Phono, CD or Tape/CDR,
is selected subsequently. It is not possible to view video while
listening to an audio-only source.
• You may select a device connected to either the front- or
rear-panel Video 3 Inputs. Press the front-panel or remote
Video 3 Source Selector repeatedly to toggle between the
front- and rear-panel Video 3 Inputs, and observe the front-
panel display indicators. When the dot to the left of the Video
3 Indicator is lit steadily, the rear-panel inputs have been
selected. When the dot flashes, the front-panel inputs are
active. When the front-panel inputs are not in use, you may
snap the supplied cover over them. Remove the cover by
pressing on the left side until it pivots outward.
• Similarly, if you have connected a three-head tape deck to the
Tape/CDR Inputs, you may monitor a recording while it is being
made so that you can confirm that the correct program material
is being recorded and make any necessary adjustments to
the recording level. When a recording is being made, the dot
to the left of the source being recorded will be lit. Press the
T-Mon Button on the front panel to hear playback from the
tape deck’s playback head. When the recording is being
monitored, the dot to the left of the Tape Monitor Indicator will
flash. Press the T-Mon Button again to hear the original source.
Using the Tuner
The HK 3485’s built-in tuner may be selected in one of two ways
(see Figure 34):
1. Press the front-panel AM or FM Button.
2. Press the AM or FM Button on the remote.
Figure 34 – Tuner Input Selection
Tuner operation requires some special keys, including the Numeric Keys,
which are normally hidden behind a door in the lower half of the remote.
To access these controls, hold the remote in one hand while grasping
the ridged finger holds on the sides of the door with the other hand.
Squeeze the door gently as you slide it toward you, revealing the
additional controls. See Figure 35.
