Denon S-81 User manual

S-81
Personal Audio System
Main Unit
■Simple, compact design with versatile connectivity and ease of use
inherited from Denon's S series
The S-81has been built on the design concept inherited from Denon's S-301 home
theater system that was released last year and has since received considerable
acclaim. This design features ease of operation combined with a visually pleasing
appearance in a round form that integrates the main unit and speakers. The front
panel on the main unit is made of tactile aluminum, and the control keys have been
arranged in a layout that make them easy to find even for beginners. The speaker
output terminals have a unique shape with easy-to-handle one-touch cable
connection jacks that are color-coded for the Left and Right channels.
■High-power 50W+50W digital amp
The compact body of the main unit houses a robust 50W+50W power amp.
Despite its compact size, this amp reproduces music through the speakers with
considerable detail and power on a rock-stable foundation. The amp also has a built-in
Speaker Optimize filter circuit that takes maximum advantage of the speakers'
characteristics to ensure high-grade audio reproduction from the overall system.
■iPod®support
The front panel includes a port for connecting
Apple Computer's iPod music player via a
dedicated cable that comes with the S-81.
iPod playback versatility can be expanded
by connecting Denon's separately available
ASD-1R iPod Control Dock to a dedicated
control port and other terminals on the rear
panel. With the ASD-1R, the user can enjoy
not only music from the iPod but also video
on a TV monitor, and the remote control unit
that comes with the S-81 can be used to
control the iPod.*
*Supports 3rd-generation and later iPods equipped with a dock connector. Some features may not work
depending on the version of the software used.
■Analog Music Input, for connecting a portable player
The front panel also provides a mini-jack input terminal for connecting a
portable digital or analog audio player and enjoying music from the
player in high sound quality.
■MP3 and WMA audio files supported
The S-81 plays MP3 and WMA audio files stored on CD-R or CD-RW discs*. Music
libraries on computers or portable digital audio players can also easily be enjoyed
through the S-81. The names of files, artists, and tracks are shown on the S-81's
large display
* Some discs may not be playable due to poor writing conditions or other factors.
■Optical digital output terminal
■Useful CD playback functions
The S-81 provides two types of playback patterns:
Repeat Play, Random play and Program Play.
■ XM Satellite Radio Ready with optional XM Passport System*
*Subscription to XM services also required.
■60-station FM/AM Preset
Up to a total of 60 FM/AM stations can be preset and called up through the system
remote control unit. A convenient Auto Preset Memory feature is also provided.
■Handy Timers
The S-81 includes an "Everyday Timer" that automatically turns on and off the power
at a preset time each day, a "Once Timer" that automatically turns on and off the
power that has been preset once during the day, and a "Sleep Timer" that automati-
cally turns off the power in a time interval that can be preset in 10-minute increments
from 10 to 60 minutes.
■Remote control unit
with simple design
The buttons that are most often used
have been arranged so that they are
easy to find and operate. The other
buttons are accessed by simply
opening a small door.
■MONO OUT terminal equipped
Speaker System
■A marriage of European sound design and Denon engineering
In the history of audio, Denon speakers have been developed on a foundation of
European taste from such countries as Denmark and England. The S-81's
speaker system represents the result of collaboration between Denon engineers and
European sound designers intimately familiar with classical music. The speakers have
been tuned to produce a European sound that tastefully matches the main unit.
These compact speakers have been carefully crafted with the latest
technology and materials to produce a sound that is sensitive to the music.

■Large 12-cm woofer unit with D.D.L. (Denon Double Layer) cone
The newly-developed D.D.L.(Denon Double Layer) cone has been used for the
woofer diaphragm. This dual-layer diaphragm whose structure is the result of
meticulous simulations is both highly rigid and light-
weight and achieves a precision piston motion
across the entire sonic spectrum. The ingenious
structural design ensures that sympathetic vibration
from the edge do not adversely affect the audio
characteristics but deliver the best possible quality
in sound. Improvements in top-bottom symmetry in
magnetic flux distribution and other areas, together
with the magnetic circuit of advanced design, bring
out a deeply impressive strength of expression.
■Soft-dome tweeter
The tweeter features a 2.5-cm soft-dome diaphragm. Designed to achieve flat
radiation impedance following a rigorous regimen of tests, the shape of the frame
helps to produce a supple sound. A highly-magnetic, low-distortion neodium
magnet has been used in the magnetic circuitry.
■Cabinet design
Metal powder has been mixed in the speaker cabinet walls to ensure that the
cabinet is not only highly rigid but also suppresses unwanted vibration. Along with
enhancing the S-81's overall sense of design, the gentle shape of the cabinet
contributes to a sense of presence as a Hi-Fi speaker. The speakers can be set up
vertically or horizontally according to the installation of the stand, or they can be
mounted on a wall using the supplied brackets. The S-81's speakers offer
considerable flexibility for system set-up.
■Speaker cables with one-touch jacks and color coding for easy connection
The connectors on the speaker cables and the speaker terminals on the amp have
been color coded-white for the Left channel and red for the Right-to simplify system
set-up. The one-touch jacks on the cables make the connection process a snap.
