Page: 9 / 51

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 3485, 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. Observe
the HK 3485’s front panel. When the dot next to the Video 3
Input Indicator lights steadily, the device connected to the rear
panel has been selected. When the dot flashes, 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 connec-
tions, then you will need to connect the Video Monitor Output to the
corresponding input on your television or video display in order 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 3485
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 3485. 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. Remember to
observe the correct polarity (positive and negative connections). Always
connect the positive lead to the red 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 Selector 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.
If you have only one subwoofer with a single line-level input, connect
it to the right Subwoofer Output on the HK 3485.
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 3485’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 Audio 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 3485’s audio inputs.
