CONNECTIONS
HK 3490, it also counts as a source, even though no external connections are needed, other than the FM and AM antennas and the XM module.
Separate connections are required for the audio and video portions of the signal.
Audio Connections
There are two formats for audio connections: digital and analog. Digital audio signals offer improved quality, free of distortion and with greater detail and presence. The HK 3490 uses two types of digital audio connections: coaxial and optical. Either type of digital audio connection may be used for each source device, but never both simultaneously for the same source. However, it’s alright to make both analog and digital
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.

Analog Audio
Analog 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 6. Most sources that have digital audio jacks also have analog audio jacks, although some older types of sources, such as tape decks, have only analog jacks. For sources that are capable of both digital and analog audio, you may wish to make both connections. If you wish to record materials from DVDs or other

Antennas
The HK 3490 uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner.
The FM antenna uses a
