Denon AVR-681 Stereo System User Manual


 
Versatile Input & Output Terminals
For maximum system flexibility, the AVR-681 is provided with an
abundance of audio and video input and output terminals. Two assignable
digital inputs, one optical and one coaxial, can be configured according to
your system's component output capabilities. The AVR-681 provides five
sets of analog inputs, along with three sets of video inputs, for total system
connection flexibility.

Personal Memory Plus, for Easy Operation
The AVR-681 includes the Personal Memory Plus function that
automatically remembers the surround mode you last used for each
program source, so that you do not need to select the mode again for
that program.
Audiophile Quality Speaker Terminals
In addition to accepting bare wire or pin terminations, the front main
speaker terminals (left, center, and right) can also accept banana-plug
terminals for full compatibility with high grade speaker cables, along
with easy connection capability.
Multi-Function Preset Memory Remote Controller
The supplied system remote controller features a large selection of
remote control codes to operate other components in your home theater
system, including codes for selected DENON models, along with remote
control codes from other manufacturers. The most frequently used buttons
are laid out separately for TV, VCR and DVD, for maximum ease-of-use.
Acclaimed Customization Feature
As with all of DENON’s high-grade A/V amplifiers, the AVR-681 lets
you adjust delay times and other parameters so that you can customize
the performance of the AVR-681 to suit your own home theater and
enhance operating ease. The adjustments are easy to make via a dialog
format on the fluorescent display on the front panel.
