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 a Cat 5 or Cat 5e
Ethernet cable.
3. Digital audio input connector (HK 3770 only): There are two audio optical inputs
labeled OPTICAL 1 and OPTICAL 2 and one coaxial input labeled COAXIAL.
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.
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 and Phono in: This is used for phono input. Plug your analog turntable
in here. Connect the outputs of your turntable to these jacks, and connect the ground
wire from the turntable to the ground connector to reduce system hum. Only moving
magnet (MM-type) cartridges are compatible with the Phono Input. 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.
7. Analog audio input connector: There are 5 audio analog inputs labeled A1 to A5
to connect your different source devices.
8. Recorder output: Connect this analog audio output to the analog audio input of a
recording device.
NOTE: Ensure that you are aware of any copyright restrictions on any
material you record. Unauthorized duplication of copyrighted materials is
prohibited by federal law.
9. Subwoofer connector: If you have a powered subwoofer, connect these jacks to the
line-level inputs on the subwoofer.
10. Speaker connectors: 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 buttons on the remote to select either or both pairs
of speakers for playback.
11. 12 V Trigger output: This connector provides 12 V DC whenever the stereo receiver
is ON. It can be used to turn on and off other devices such as a powered subwoofer.
