1. Radio Antenna connector : connect the included aM and FM antennas to their
respective terminals for radio signal reception.
2.
Network Connector : connect to your home network using Rj45 connector.
3.
Digital audio input connector (HK 3770 only)
: If your non-HdMI source devices
have digital outputs, connect them to the receiver’s digital audio connectors.
NOTE: Make only one type of digital connection (HDMI, optical or coaxial)
from each device.
4. IR in and trigger connector : when the IR remote receiver on the front panel of
the HK 3700/3770 receiver is blocked, connect an optional IR receiver to the IR Remote
Input jack for use with the remote control. the Remote IR Output may be connected to
the IR Remote Input of a compatible source device (or other product) to enable remote
control through the HK 3700/3770. when several source devices are used, connect them
in a “daisy chain” fashion.
Trigger Connector
: 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 3700/3770 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.
5.
AC input connector
: after you have made all other connections, plug the supplied
ac power cord into an unswitched wall outlet.
6.
Signal GND : this is used to connect the ground wire of an analog player. this reduces
noise when an analog player is connected.
7.
Phono in : connect the outputs of your turntable 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 on board phono preamp, you may connect it to any
of the HK 3700/3770’s other audio inputs.
8.
Analog audio input connector
: use the receiver’s analog audio Input/Output
connectors for source devices that don’t have HdMI or digital audio connectors. use the
Video 2 Out and tape Out connectors to connect to the audio inputs of a VcR and tape
deck.
9.
Recorder
: two-channel analog audio signals, as well as composite video signals, are
normally available at the appropriate recording outputs. thus, to make a recording, you
need only make sure to connect your audio or video recorder to the appropriate output
jacks. Insert blank media and make sure the recorder is turned on and recording while
the source is playing.
NOTE: Please make certain that you are aware of any copyright restrictions
on any material you record. Unauthorized duplication of copyrighted
materials is prohibited by federal law.
10.
Subwoofer connector
: If you have a powered subwoofer, connect these jacks to
the line-level inputs on the subwoofer.
11.
Speaker connector : use two-conductor speaker wire to connect each set of
terminals to the correct speaker. Observe the correct polarity (positive and negative
connections). use the Speaker 1/2 Selectors on the front panel or remote to select either
or both pairs of speakers for playback.
