Denon AVR-1800 Instructions

By Candace Horgan

The AVR-1800 was a basic five-channel audio receiver introduced by Denon in 1999. It was replaced by the 1801 model in 2000. The receiver can put out 75 watts per channel and has basic video connections (composite), plus digital connections for TOSLINK and S/PDIF inputs.


Do not connect video to the AVR-1800. Unlike more modern receivers, you cannot run HD video or DVD video through the AVR-1800, unless you use composite connections, which is a significant downgrade from component video, S-video and HDMI connections. If you have an HDTV and an AVR-1800, it is best to run video connections straight to the TV and audio connections to the AVR-1800.

For audio, in addition to standard left/right analog audio connections, the AVR-1800 has two TOSLINK optical connections and one S/PDIF digital connection. Use the S/PDIF for the DVD and the TOSLINK for your HD cable or satellite box.

Connect the speakers to their appropriate terminals, using banana plugs or by sliding the wire through the terminals and tightening them down.

Assign the Digital In

Go to the setup menu and assign the digital inputs to the appropriate connection. Power on the receiver, press the System Setup key on the remote to go to the setup menu and use the up/down arrows to go to "Digital In Assignment." Assign "Coaxial" digital in to DVD, and assign "TOSLINK 1" to TV/DBS.

Speaker Configuration

Press System Setup and go to "Speaker Configuration." The default setup is "Large" for front speakers and "Small" for center and surrounds. If you have bookshelf speakers for the front, change front to "Small"; if you have a large surround or rears, change the configuration to "Large."

Go to "Delay Time" next. Measure the distance of the front speakers, center speaker, subwoofer and surrounds from the main listening position in the room and enter that information in the appropriate speaker fields. The default is 12 feet for front and center and 10 feet for surrounds.
