With AirPlay, you can enjoy listening to your songs wirelessly from your portable iOS device, including iPhone, iPod touch and iPad. Certification DLNA 1.5 allows you to connect to a PC or Mac via your home wireless network for additional features streaming. Our own Denon Remote App lets you easily check the AVR-X4100W with your mobile device and is available for Apple and Android devices, and the Kindle Fire.
Easy to Install, Easy to Use
Exclusive Installation Guide Denon, together with our Introductory Handbook, ensures proper connection of your system easy and quick configuration, so you can enjoy perfect surround sound home theater system with minimum disruption and difficulty. The Installation Guide has sharp graphics and text, guiding you quickly and easily in the installation process, optimizing critical system settings for the best possible sound quality.
Powerful Amplifier 7-Channel Discrete Reinforcement Layout with Eco Mode
With maximum power channels of 200 watts each, the AVR-X4100W final design features support multiple high-current output devices with identical circuit topology for all seven channels. Our new Eco Mode allows reducing the overall energy consumption and has Eco Meter on the screen, allowing you to see graphically the reduction of energy consumption. The Auto Eco mode automatically switches between normal energy consumption and Eco modes, depending on the selected volume level. The final portion of aid may lead loads low-impedance until the 4 ohms, for compatibility and stability with almost any speaker model.
Audyssey MultEQ-XT32 / LFC
It is the most accurate room correction solution with more than ten thousand individual control points, allowing to identify the smallest details of the room problems and corrected. The ultra high resolution filters are applied to all channels, including two independent subwoofers, with the obvious advantage of sound in low frequency range, where most demand is the correction. The Audyssey LFC uses psychoacoustics algorithms to prevent the bass so you do not spend your walls and disturbing your neighbors, while keeping the bass performance in listening room. The AVR-X4100W is also prepared for Audyssey Pro for the more advanced professional room correction.
Multiroom / Multisource
The AVR-X4100W lets you enjoy program source in the Main Zone (the room where is placed the AVR-X4100W) and Zone 2 and Zone 3. The source may be the same for all zones or you can enjoy different sources in these areas, if desired. The sources for the zones can be either analog or digital 2 channel PCM sources (including optical, coaxial, HDMI and network).

| For a long time, installers worldwide have been unhappy with consumer electronics and they were looking for a professional integrated amplifier for use in commercial environments, boardrooms or small businesses designed for 24/7 operation. Therefore Apart developed the CONCEPT1, a stereo or two mono channel (2 x 80 watts @ 4 ohms) amplifier for small and medium-sized projects.
This CONCEPT1 2-zone integrated stereo amplifier can operate with one stereo zone, two volume-linked mono zones or two individual-volume mono zones. The unit can be controlled via RS232 what makes integration into your AV solution possible. The built-in limiters and system design guarantee a failsafe solution 24 hours a day, 7 days a week.
To make the life of the end-user as easy as can be, the CONCEPT1 has user settings and installer settings. Only the absolute
