OPERATION
should be heard most clearly at a point exactly midway between the left
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 33.
Figure 33 – 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 3490, 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 34.

Speaker 1/2
The HK 3490 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 35.
Figure 35 – 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 3490 for playback by
pressing its associated button on the front panel or remote control.
See Figure 36.
Figure 36 – Source Selectors
To enjoy video sources, make sure to connect the device’s composite
video output to the correct Video Input on the HK 3490. In addition,
connect the HK 3490’s Video Monitor Output to an input on your
television or video display.
To select whether the source will use its analog audio input or one of
the digital audio inputs, press and hold the front-panel Source Selector
and simultaneously tap the front-panel T-Mon Button repeatedly until the
desired input appears in the Message Display. Audio input selection
requires use of the front-panel controls and cannot be selected using
the remote control.
To 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,
as indicated in 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.
NOTES:
• The HK 3490 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 3490 cannot decode digital
surround-sound programs. If you have connected the analog
audio and composite video outputs of a DVD player to the
HK 3490, remember to select two-channel audio in the DVD
player and disc menus. However, you may press the DSP
Surround Button to select a Dolby Virtual Surround mode
(Reference or Wide) to expand the presentation of the sound
field even though only two main loudspeakers are in use.
