AM Antenna and Clamp
A molded plastic loop antenna is supplied with your AVC-1800. Connect the two wires of
the AM loop antenna to the posts labeled AM and GND. Position the loop antenna for best
AM reception. If you are trying to pick up very distant stations, you may connect a single
long wire to the AM terminal and a good earth ground to the GND terminal. Once you have
connect the AM antenna, fasten it to the antenna clamp on the rear panel.
Bass Management Switches
Bass management is designed to assure overall balanced response by accommodating many
different types of speaker systems that may or may not be able to reproduce frequencies
below 80 Hz. The Bass Management switches allow you to configure your speakers to
reproduce low frequencies below 80 Hz, or to filter out these frequencies and route them to
your front speakers or only to your subwoofer channels. The AVC-1800 has four toggle
switches, which you must set according to the characteristics of your speakers. Refer to the
setup section of this manual for more details on setting the bass management switches to
accommodate your home theater system.
NTSC/PAL Switch
This switch allows you to select the display default system to be for the NTSC or PAL video
format. PAL is the video format in most European countries and NTSC is the predominant
video format in other regions. If you select the incorrect format, the on-screen display will
not synchronize properly with your television and will look scrambled.
Input Connections
Analog Audio 1-3 Input Connections
The three audio-only analog inputs are compatible with typical analog line level sources
such as CD players, MiniDisc players, cassette decks, etc. Connect the left and right analog
audio outputs of your audio source components to these inputs. You can also “assign” any of
the four Digital audio inputs to accompany any of these three Audio analog inputs.
Audio Only Record Output Connections
The audio signal from the source you select for the main zone is routed to the Record Output
connectors of Audio 1. Connect the left and right play/output of your tape deck to the left
and right Audio 1 input connectors. Next, connect the left and right Record Output connectors
of your AVC-1800 to the left and right audio record/input connectors of your tape deck.
Analog Audio/Video 1-4 Input Connections
All four Audio/Video analog inputs are compatible with typical line level sources such as
DVD players, videocassette recorders, satellite receivers, cable converter boxes, etc. Each
of the four Audio/Video inputs also switches an accompanying NTSC/PAL composite video
and an S-Video input. You can also assign any of the four Digital audio inputs to accompany
these four Audio/Video inputs. If you have a DVD player, be sure to connect its digital
output to one of the digital inputs of the AVC-1800 for digital surround decoding.
S-Video and Composite Video Input Connections
Each of the four Audio/Video inputs has both composite and S-Video connectors with separate
video circuits and amplifiers. The AVC-1800 cannot convert video signals from S-video to
composite video, or vice versa. For example, when you connect a video signal to one of the
four RCA composite RCA input jacks, the proper video signal will only be available through
the RCA composite Monitor and Record output jacks. If you try to cross video platforms,
the signal will be black and white and distorted.
