REAR-PANEL CONNECTIONS
AM and FM Antenna Terminals:
Connect the included AM and
FM antennas to their respective terminals for radio reception.
Video 1, Video 2 and Video 3 Audio/Video Inputs:
These
jacks may be used to connect your video-capable source components
(e.g., VCR, DVD player, cable TV box) to the receiver.
NOTE: The Video 3 source has inputs on both the front and
rear panels of the HK 3390, and you may connect different
devices to each set of inputs. To select between the two sets of
inputs, press the Video 3 Source Selector repeatedly. When
VIDEO 3 appears in the Message Display, the device connected
to the rear panel has been selected. When VIDEO F appears,
the device connected to the front panel has been selected.
Video 1 Audio/Video Outputs:
These jacks may be used to
connect your VCR or another recorder.
Video Monitor Output:
If some of your sources use video
connections, connect the Video Monitor Output to the corresponding
input on your television or video display to view the sources. No video
signal will be available when an audio-only source input, such as CD
or Tape, is selected.
Remote Infrared (IR) Input and Output:
When the remote
IR receiver on the front panel is blocked, such as when the HK 3390
is placed inside a cabinet, connect an optional IR receiver to the
Remote IR Input jack for use with the remote control. The Remote
IR Output may be connected to the Remote IR Input of a compatible
source device (or other product) to enable remote control through the
HK 3390. When several source devices are used, connect them in
“daisy chain” fashion.
AC Power Cord:
After you have made all other connections, plug
the AC power cord into an unswitched outlet.
Switched AC Accessory Outlets:
You may plug the AC power
cord of one source device into each of these outlets, and it will turn on
whenever you turn on the receiver. Do not use sources that consume
more than 100 watts of power per outlet.
Speaker 1 and 2 Outputs:
Use two-conductor speaker wire to
connect each set of terminals to the correct speaker. Observe the
correct polarity (positive and negative connections). Always connect the
positive lead to the red or white terminal on the receiver and the red
terminal on the speaker. Connect the negative lead to the black terminal
on both the receiver and the speaker. Use the Speaker 1/2 Selectors
on the front panel or remote to select either or both pairs of speakers
for playback.
Subwoofer Outputs:
If you have a powered subwoofer, connect
these jacks to the line-level inputs on the subwoofer. The same full-
range signal is output through both jacks. Thus, you have the option of
connecting each jack to the line-level input on a separate subwoofer, or
to use these full-range outputs to feed a remote room in a distributed-
audio application. If you have only one subwoofer with a single line-level
input, connect it to the right Subwoofer Output on the HK 3390.
Subwoofer Trigger Outputs:
Connect these outputs to a
compatible trigger input on the subwoofer connected to the Subwoofer
Output immediately to the right of the Trigger Output. Consult the
owner’s manual for the subwoofer to set its trigger input correctly,
and the subwoofer will automatically turn on or off when the HK 3390
is turned on or off. In addition, the Trigger Outputs are used with the
Subwoofer Link Switches to conserve energy by powering off the
subwoofer’s amplifier when it is not needed. The Subwoofer Trigger
Outputs send a signal of 15 volts DC.
Subwoofer Link Switches:
Each switch affects the subwoofer
connected to the jack immediately to the left of the switch. To use
the switch, first connect the corresponding Subwoofer Trigger Output
to a compatible trigger input on the subwoofer, and make sure the
subwoofer’s instructions are followed to activate its trigger input. When
the Link Switch is on, the HK 3390 will remove the trigger signal
whenever the corresponding pair of main speakers are not in use,
thereby conserving energy that would otherwise be used to maintain
the subwoofer’s amplifier in standby mode. This feature is activated
any time no signal is present at the main speaker outputs, including
when the Speaker 1/2 Switch turns off both speaker pairs, when the
HK 3390’s output is muted, or when the headphones are plugged in.
See Table A2 in the appendix for details.
Main-Amp Inputs and Preamp Outputs:
These jacks are
normally connected directly to each other with an included jumper.
Some devices, such as equalizers and some loudspeaker systems,
require connection between the Preamp Outputs and Main-Amp Inputs,
in which case the jumpers should be removed and stored in a safe
place for future use. You may also remove the jumpers if you wish to
connect the Preamp Outputs to an external amplifier, or if you wish
to connect another device’s line-level output directly to the HK 3390’s
power amplifier for a special application.
Tape Outputs:
These jacks may be used to connect your CDR or
another audio-only recorder.
CD and Tape Inputs:
These jacks may be used to connect your
audio-only source components (e.g., CD player, tape deck). Do
not connect a turntable to these jacks unless you are using the turntable
with a phono preamp. When your recorder features three-head or
off-head playback, you may monitor a recording as it is being made.
Phono Inputs and Ground:
Connect the outputs of your turntable
or tonearm to these jacks, and connect the ground wire from the
turntable to this Ground Connector to reduce system hum. Only moving-
magnet (MM-type) cartridges are compatible with the Phono Inputs. If
your turntable is equipped with its own onboard phono preamp, you
may connect it to any of the HK 3390’s other audio inputs.
Main Power Switch:
This mechanical switch turns the power supply
on or off. It is usually left turned on (push the rocker in at the top), and
cannot be turned on using the remote control. Turn this switch off when
connecting or disconnecting source devices or loudspeakers to prevent
any possibility of damage to components resulting from an unexpected
power surge.
