A CD receiver (RCD-S81) and speaker systems (SC-S81) can be easily connected to the S-81 using the speaker cables included with the S-81.
Changing the speaker cable
The speaker cable can be replaced with another one of your choice. Here we describe how to connect the + side cable to the connector. Connect the side cable in the same way.
Note on speaker impedance
If speakers with an impedance below the specified impedance (4 /ohms) are used (for example, speakers with an impedance of 3 /ohms) with the volume turned up high for long periods of time, the temperature may rise, activating the protective circuit. When the protection circuit is activated, the output to the speakers is cut off and the power indicator blinks. If this happens, unplug the power supply cord, wait for the set to cool off and improve ventilation around the unit. Also check the wiring of the input cables and the speaker cables. After doing this, plug the power supply cord back in and turn the units power back on. If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off the power and contact a DENON service center.
wrench 1 Insert the hexagonalside of the(included) into the hole in the + side connector (arrow A).

Noise may be produced in the sound when receiving AM broadcasts if there is a monitor or other such device nearby. If so, move the S81 and monitor as far apart as possible.

Personal Audio System

Main Unit

s Simple, compact design with versatile connectivity and ease of use inherited from Denon's S series The S-81 has 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. s 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. s 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.
s Optical digital output terminal s Useful CD playback functions The S-81 provides two types of playback patterns: Repeat Play, Random play and Program Play. s XM Satellite Radio Ready with optional XM Passport System* *Subscription to XM services also required. s 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. s 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 automatically turns off the power in a time interval that can be preset in 10-minute increments from 10 to 60 minutes. s 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.
s MONO OUT terminal equipped

Speaker System

s 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.
s 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. s 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.

s 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 lightweight 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. s 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. s Antimagnetic design s 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. s 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.
