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 7.

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.

The analog audio connection is strongly recommended if you intend to
use the source with the multiroom system. It’s required if you will be
using the multiroom preamp outputs with an external amplifier to power
your remote speakers, as the AVR 247’s multiroom system is not capa-
ble of converting the digital signal to analog format. It’s suggested that
you also use the analog audio connections when using the surround
back/multiroom speaker outputs, in case another two-channel digital
audio source is in use in the main listening area. The AVR 247 is only
capable of processing one PCM source at a time.

If you wish to record materials from DVDs or other copy-protected
sources, you may only do so using analog connections. Remember to
comply with all copyright laws, if you choose to make a copy for your
own personal use.

Figure 7 – Analog Audio

Multichannel analog connections are used with some high-definition
sources where the copy-protected digital content is decoded inside the
source. These types of connections are usually used with DVD-Audio,
SACD, Blu-ray Disc, HD-DVD and other multichannel players. See
Figure 8. However, the multichannel analog audio connection is not
required for DVD-Audio players compliant with HDMI version 1.1 or
better, or HD-DVD and Blu-ray Disc players that decode the digital audio
internally and output linear PCM signals in digital format. Consult the
owner’s guide for your disc player for more information.

Harman Kardon receivers also include a proprietary, dedicated audio
connection called “The Bridge/DMP”. If you own an iPod with a dock
connector, you may purchase The Bridge separately and connect it to
The Bridge/DMP port on the receiver. See Figure 9. Dock your iPod
(not included) in The Bridge, and you may enjoy your audio and video
materials through your high-performance audio/video system. You may
even use the AVR 247 remote to control the iPod, with navigation

messages displayed on the front panel and on a video display connected
to the AVR. The Bridge outputs analog audio to the AVR 247, and it is
available to the multiroom system.

Video Connections

Although some sources produce an audio signal only (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, connect one type of video connec-
tion for each source (never more than one at the same time for any
source).

Digital Video

If you have already connected a source device to one of the HDMI
inputs as explained in the Digital Audio Connections section, then you
have automatically made a video connection at the same time, as the
HDMI signal includes both digital audio and video components.

If the source device is not capable of transmitting its digital audio signal
through the HDMI connection, then use one of the coaxial or optical
digital audio inputs for the source.

If a multichannel analog audio connection is required for certain lossless
formats (e.g., DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you may
make both connections, but you must also make an analog video con-
nection. To listen to the multichannel disc, first select the analog video
source input, then select the 6-/8-channel analog audio inputs, and the
AVR will retain the last video source you selected other than HDMI.

The AVR 247 is Simplay HD-verified for compatibility via the HDMI
connection with other Simplay HD-verified products.

Analog Video

There are three types of analog video connections: composite video,
S-video and component video.

Composite video is the basic connection most commonly available. The
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 or coaxial digital audio jack, or vice versa.
Both the chrominance (color) and luminance (intensity) components of
the video signal are transmitted using a single cable. See Figure 10.

Figure 10 – Composite Video

S-video, or “separate” video, transmits the chrominance and luminance
components using separate wires contained within a single cable. The
