Using the DENON original surround modes
The AVR-687 is equipped with a high performance digital signal processor (DSP) that uses digital signal processing to recreate sound fields
artificially. One of seven surround modes can be selected according to the program source and parameters can be further adjusted to achieve
even more realistic sound fields.
Types of surround modes and their features
This mode recreates the atmosphere of a live concert in an arena.
This mode recreates the atmosphere of a live concert in a club with low ceilings, hard walls and the artist just in
front of you.
This mode provides a rich sense of presence for video games.
This mode recreates the atmosphere of an expansive sound field for movie sources recorded in monaural.
This mode recreates music sources recorded in stereo with an enhanced sense of expansion.
This mode can be used to enjoy surround sound with only front speakers or when using headphones.
NOTE 1: “5CH STEREO” is displayed when “SB CH OUT” is set to “OFF”.
NOTE 2: When playing sources recorded in monaural, the sound will be one-sided if signals are only input to one channel (left or right), so input
signals to both channels. If you have a source component with only one audio output (monophonic camcorder, etc.) obtain a “Y”
adapter cable to split the mono output to two outputs, and connect to the L and R inputs.
• Depending on the program source being played, the effect may not be very noticeable. In this case, try other surround modes, without
worrying about their names, to create a sound field suited to your tastes.
This mode lets you enjoy stereo sound with seven speakers. The front L (R) channel signals are played from the
surround and surround back L (R) channels and only the in-phase component of the L and R channels is played on
the center channel.
