OPERATION
and right speakers, unless the artist has mixed the recording in a way
that pans sounds to one side or the other. If your speakers are not
placed the same distance from the listening position, or if your room
has other unusual characteristics, gently press the Balance Control knob
until it unlatches and pops out. Then turn it counterclockwise to move
the sound toward the left speaker or clockwise to move the sound
toward the right speaker. See Figure 30.
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 3390, then both will
be affected.
IMPORTANT NOTE: Do not attempt to install the front-panel
covers with the tone and balance control knobs in the unlatched
position. Gently press each knob until it latches. When locked,
the controls cannot be adjusted, preventing inadvertent changes
to your desired settings.
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 3390 may be used with up to two pairs of speakers for
additional 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. When either of the speaker
pairs are deactivated, if the corresponding Subwoofer Trigger Output is
connected to the subwoofer and the corresponding Subwoofer Link Switch
is on, the trigger signal will be deactivated, turning off the subwoofer
amplifier and conserving energy when the subwoofer is not needed.
Source Selection
Select a source device connected to the HK 3390 for playback by
pressing its associated button on the front panel or remote control.
See Figure 33.

To enjoy video sources, make sure to connect the device’s composite
video output to the correct Video Input on the HK 3390. In addition,
connect the HK 3390’s Video Monitor Output to an input on your
television or video display.
NOTES:
• The HK 3390 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 3390 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 3390, remember to select
two-channel audio in the DVD player and disc menus.
• The HK 3390 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. 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.
• 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. 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 T-MON message will flash.
Press the T-Mon Button again to hear the original source.
Using the Tuner
The HK 3390’s built-in tuner may be selected in one of two ways
(see Figure 34):
1. Press the front-panel AM or FM Button.
