Connections
Connecting the Speakers
Speaker cables carry an amplified signal from the stereo receiver’s speaker terminals
to each loudspeaker. Each cable contains two wire conductors or leads that are
differentiated in some way, such as with colors or stripes.
The differentiation helps you maintain proper polarity, without which your receiver’s
low frequency performance may suffer. Each speaker is connected to the stereo
receiver’s speaker output terminals using two wires, one positive (+) and one negative
(–). Always connect the positive terminal on the speaker, which is usually colored red,
to the positive terminal on the stereo receiver. The negative terminals on the speakers
and the stereo receiver are black.
Always connect the colored (+) terminal on the stereo receiver to the (+) terminal on
the speaker (usually red), and the black (–) terminal on the stereo receiver to the (–)
terminal on the speaker (usually black).
Connect your speakers as shown in the illustration.
IMPORTANT: Make sure the (+) and (–) bare wires do not touch each other or
the other terminal. Touching wires can cause a short circuit that can damage
your stereo receiver. Connect the speakers as shown in the illustration.
Connecting the Subwoofer
Use a single RCA audio cable to connect your subwoofer to the stereo receiver’s
Subwoofer Pre-Out connector as shown in the illustration below. Consult your
subwoofer’s user manual for specific information about making connections to it.

Connecting Source Devices
The HK 3700/3770 is designed to process audio input signals and playback the audio.
These signals originate in what are known as source devices including your DVD player,
CD player, DVR (digital video recorder) or other recorder, tape deck, game console,
cable or satellite television box, or MP3 player. Although the tuner is built into the HK
3700/3770, it also counts as a source, even though no external connections are needed,
other than the FM and AM antennas.
Connecting the Radio Antennas
1. Connect the supplied FM antenna to the stereo receiver’s
FM 75 Radio Antenna connector. For the best reception,
extend the FM antenna as far as possible.
2. Bend and fold the base of the supplied AM antenna as shown and
connect the antenna wires to the stereo receiver’s AM and GND
connectors (you can connect either wire to either connector). Move
the antenna as necessary to minimize background noise.
