CONNECTIONS
Analog Audio Connections
Analog audio connections require two cables, one for the left channel
(white) and one for the right channel (red). These two cables are often
attached to each other for most of their length. See Figure 4.

Video Connections
Although some sources only produce an audio signal (e.g., CD player,
tape deck), many sources output both audio and video signals (e.g.,
DVD player, cable television box, HDTV tuner, satellite box, VCR, DVR).
In addition to the audio connection, make a video connection for each
of these sources.
The composite video jack is usually color-coded yellow, and looks like an
analog audio jack, although it is important never to confuse the two. Do
not plug a composite video cable into an analog audio jack, and vice
versa. Both the chrominance (color) and luminance (intensity) components
of the video signal are transmitted using a single cable. See Figure 5.

Antennas
The HK 3390 uses separate terminals for the included FM and AM
antennas that provide proper reception for the tuner.
The FM antenna uses a 75-ohm F-connector. See Figure 6.
Figure 6 – FM Antenna
The AM loop antenna needs to be assembled. Connect the two leads
to the spring terminals on the receiver. The AM antenna leads are
polarized, and it is important to color-match the leads and terminals
to maintain the proper polarity. See Figure 7.
