Harman Kardon AVR 245, Service Manual

Page: 19 / 228

NOTE: The AVR 245 is equipped with a total of six digital audio inputs, four on the rear panel (Coaxial 1 and 2, Optical 1 and 2) and two on
the front panel (Coaxial 3 and Optical 3). However, there are a total of nine sources that may be connected to devices that have digital audio
outputs. We recommend certain digital audio connections simply because, as reflected in Table A1 of the Appendix, those digital audio inputs
are assigned to the particular sources by default at the factory. But any digital audio input may be reassigned to any source. Since you may
not be using all nine source inputs, you may reassign a digital audio input that is recommended for a source you aren’t using to another
device. Table 2 is a guideline; you may need to make adjustments to fit your system.

INSTALLATION
Video 1 Source
Since this source includes audio and video recording output jacks, it is
best suited to a video recorder, such as your VCR or DVR.
Referring to Table 2, connect your recorder to the Video 1 Analog Audio
inputs and outputs
and to any available coaxial or optical digital audio
input (and corresponding digital audio output). See Figure 20. Use either
the Video 1 S-video or composite video input and output if you wish to
make recordings. If you don’t plan on recording, you may use the
Component Video 2 inputs.
Figure 20 – Video 1 A/V Inputs and Outputs, and Digital Audio Inputs and Outputs
Remember to connect the audio and video output jacks on your
recorder to the Video 1 or digital audio input jacks on the AVR, and the
audio and video input jacks on your recorder to the Video 1 or digital
audio output jacks on the AVR.
NOTE: It isn’t possible to make recordings using component
video connections. Keep this in mind as you connect other
source devices that you may wish to make recordings from.
Video 2 Source
The Video 2 source is used only for playback, never recording. The
AVR 245 remote control is programmed to operate many brands and
models of cable and satellite television devices, and we recommend
connecting your cable or satellite set-top box to this source.
Referring to Table 2, connect your set-top box to the Video 2 Analog
Audio inputs
and to the Optical 1 Digital Audio input. If possible, use
the Component Video 3 inputs. Otherwise, connect the set-top box’s
S-video or composite video output to the matching Video 2 video input.
See Figure 21.

Video 3 Source
The Video 3 source is used for playback only, never recording. The
remote control is programmed to accept codes that will operate a TV,
but you may connect any audio/video source device to the Video 3
inputs and use the device’s own remote to control it.
If you receive your television programming using your TV with an
antenna or direct cable connection, then you will need to connect the
analog audio outputs (if available on your TV) to the Video 3 Analog
Audio inputs. See Figure 22.
Do not connect any video output on the
television set to any video input on the receiver. See Step Five for infor-
mation on connecting the receiver’s video monitor outputs to the TV.

Video 4 Source
The Video 4 source is used only for playback, never recording. It is also
generally reserved for components that are only temporarily connected
to the receiver, such as cameras and game consoles. When not in use,
you may place the supplied covers over the front-panel Video 4 jacks
for a cleaner appearance. Simply snap the covers in place. When you
wish to use the jacks, gently press on the left side of each cover to pivot
it out for removal.
Referring to Table 2, connect your camera or game console to the
Video 4 Analog Audio inputs
and to either the Coaxial 3 or Optical 3
digital audio input. Connect the component’s S-video or composite
video output to the matching Video 4 video input. See Figure 23.
