Input and Output Notes
High-Current (+/- 42 amps) Stereo Amplifier: The built-in
amplifier has high-current capability to handle demanding loads. Although the
receiver is made to be used with 8 ohm speakers, the amplifier sees a 4 ohm load
when two sets of 8 ohm speakers are connected and both speaker outputs are on.
The high-current capabilities of the amplifier allow it to simultaneously drive
two sets of 8 ohm speakers without difficulty.
iPod: The included A/V adapter cable (3.5mm mini-jack to
RCA) can be used to connect the audio and video output of many iPod models the
the HK3490; the iPod classic, touch, and iPhone are not compatible with the
included cable for video or photo output (audio only).
Remote In/Out Jacks: There is one 3.5mm mini-jack remote
input and one 3.5mm mini-jack remote output on the rear panel of this unit. If
the receiver is placed behind a solid or smoked glass door, the obstruction may
prevent the front panel IR sensor from receiving commands from the remote. If
the unit is positioned so the front panel IR sensor cannot receive commands
from the remote, an optional IR repeater system may be connected to the Remote
IR In jack and positioned to accept commands from the remote. The Remote IR Out
jack can be connected to the remote input jack of compatible equipment to relay
commands to that equipment.
Sleep Timer: You can program the receiver's sleep timer to
turn it the unit off after a preset amount of time; choose from 90, 80, 70, 60,
50, 40, 30, 20, or 10 minutes. Once the sleep timer has been engaged, the display
will dim to half-intensity and the amount of time remaining will count down.
Remote: The included remote (HK 3390) is preprogrammed to
control harman/kardon DVD players, CD players, CD recorders, and the DMC 1000
digital media server.
Display Dimmer: The display brightness can be set to full
intensity, half intensity, or off. This feature is activated from the remote
only. When the display is dimmed or turned off, the light around the volume
knob also turns off.
Input and Output Notes
Speaker Terminals: There are binding post outputs for 2 pair
of speakers, labeled Speaker 1 and Speaker 2. The terminals are not 5-way binding
posts because each post has a plastic collar that prevents use with spade lugs.
Pre-out/Main-in Loop: Factory jumpers connect the main
amplifier input to the full range preamp outputs. This offers the flexibility
of inserting an equalizer, surround processor (when using multiple amps), or
another type of processor between the two stages.
Subwoofer Preamp Output Jacks: There are two subwoofer preamp
output jacks on the rear panel of the receiver. These jacks are provided for
connection to powered subwoofers with line-level inputs. Each sub output has a
corresponding trigger output and link switch, allowing you to automatically turn
a compatible powered subwoofer on/off along with the HK 3390's speaker outputs.
Headphone Jack: There is a full-size (1/4") headphone
jack on the front panel. When headphones are plugged in the speaker outputs are
Switched AC Outlets: There are two switched AC outlets on
the rear panel; the maximum output is 100 watts each.
- 8 Ohms: 80 watts per channel,
20Hz-20kHz @ 0.07% THD, both channels driven
- 4 Ohms: 100 watts per channel,
20Hz-20kHz @ 0.2% THD, both channels driven
Best Frequency Response: 10Hz-110kHz (1W, +0dB, -3dB)
Weight: 20.9 pounds
