Standard definition video sources such as VCR and DVD are upconverted to high definition HDMI, which allows for a single HDMI cable run to the TV, avoiding the expense and hassle of multiple cable runs.
Easy Setup With Automatic Room Acoustic Correction
Audyssey MultEQ dynamic room acoustic correction system features a microphone (included) to automatically measure the speaker configuration and provide acoustic tailoring for the best surround sound experience. Dynamic Volume helps eliminate jarring volume jumps during commercials, and Dynamic EQ provides a rich tonal balance at any volume level.
Quality Discrete Power Amplifier Section
The equal power amp design features 7 discrete power amp circuits, and each channel is rated at 90 watts (8 ohms, 20 Hz to 20 kHz, .08% THD). 2 of the amp channels can be configured for surround back, or front height effects, or they can be assigned for stereo multi-room use.
7-Channel Equal Power
7-Channel Equal Power is a feature used in various Denon amplifiers to connect 7 speakers independently so that separate power amps connected via pre-outs are not required. It allows you to connect the second 'surround back' speaker to complement the surround back speaker for 6.1, straight off the main amplifier without adding a power amplifier to support 7.1 surround formats. Amplifiers with 7-Channel Equal Power have built-in separate internal amplifiers to power each channel independently, thus allowing you to enjoy the same high power output capability per channel, giving a balanced and truly high-impact surround-sound environment.
7-Channel Stereo
Denon's 7-Channel Stereo mode enables top quality normal two channel stereo output from the surround speakers to provide a unique 7 channel stereo option. This mode can be fully utilized from any high quality stereo source via CD, tape, FM-radio or video recorder for dynamic 7-channel output. The 7-channel stereo is available if you have a surround back right speaker connected as well as the surround back left speaker used in 6.1, otherwise you can still experience multi-channel stereo output using a 5-channel-stereo or 6-channel-stereo configuration.
Audyssey Dynamic Volume
Audyssey Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies.
Audyssey MultEQ
Room acoustic measuring and correction system analyzes (via the included microphone) the audio characteristics of your speaker system and your listening environment at up to 6 measurement points and automatically tailors the sound for top audio fidelity.
Auto Set-Up/Room EQ Adjust
The Auto Set-Up/Room EQ Adjust feature eases setup hassles by confirming speaker phase, assessing the sizes of all of your speakers, measuring speaker-to-listener distances, and balancing speaker levels. With the Denon DM-A405, DM-S205 or DM-S305 calibration-grade microphone (some optional) placed in your favorite listening seat, this feature uses a test tone generator and proprietary programming to precisely balance speaker levels and fine-tune the delay and EQ settings for each speaker. The result is optimized system performance for your specific home theater room.
Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, dts, or other formats emphasizes high-frequency range due to a theaters front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range can be too strong. Denon amplifiers feature a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to.
Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to 5.1 channels – front left, front right, center, surround left, surround right, and an additional channel exclusively reserved for additional deep bass sound effects. Dolby Digitals main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies – 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging and tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.
Dolby Digital Plus
Next-generation multichannel audio format. Delivers up to 7.1 channels of better-than-DVD-quality surround sound in Blu-ray discs. Advanced coding efficiencies facilitate BD-Live and Bonusview playback and enable rich surround sound audio from digital broadcast,IPTV,and streamed and downloadable media.
Dolby Pro Logic IIx
Dolby Pro Logic IIx furthers the matrix decoding technology of Dolby Pro Logic II to decode audio signals recorded on two channels up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel sources to be played in up to 7.1 channels. The mode can be selected according to the source – Music mode is best suited for playing music, Cinema mode for playing movies, and Game mode for playing games.
DTS 96/24
DTS-ES® is used to describe 6.1 channel extended surround sound. DTS Neo:6 is used to describe our matrix technology that takes any 2-channel source material and emulates an immersive surround sound experience using a multi-channel surround sound system. DTS 96/24 is used to describe the high resolution technology featuring 96 kHz sampling rate and 24-bit word length
dts Digital Surround
dts Digital Surround (also called simply dts) is a multi-channel digital signal format developed by Digital Theater Systems. dts is a 5.1-channel surround sound format that is available in movie theaters, and as an optional soundtrack on some DVD-Video movies for home theater viewing. The primary advantage of dts is that it offers higher data rates, leading many home theater enthusiasts to claim the sound quality for movie or music audio tracks to be closer to the original master recordings.
dts-ES Extended Surround
dts-ES Extended Surround is a new multi-channel digital signal format developed by Digital Theater Systems. Used professionally in movie theaters since 1999, dts-ES Extended Surround greatly improves the 360-degree surround impression and space expression thanks to further expanded surround signals. In addition to the 5.1 surround channels, dts-ES Extended Surround also offers Surround Back, sometimes also referred to as surround center channel for surround playback with a total of 6.1 channels. dts-ES Extended Surround includes two signal formats with different surround signal recording methods, dts-ES Discrete 6.1 and dts-ES™ Matrix 6.1.
dts Neo:6 surround
This mode applies conventional 2-channel signals to the high precision digital matrix decoder used for dts-ES Matrix 6.1 to achieve 6.1-channel surround playback. High precision input signal detection and matrix processing enable full band reproduction (frequency response of 20 Hz to 20 kHz or greater) for all 6.1 channels, and separation between the different channels is improved to the same level as that of a digital discrete system. dts Neo:6 surround includes two modes for selecting the optimum decoding for the signal source – dts Neo:6 Cinema and dts Neo:6 Music
GLO-KEY Technology
The keys on the remote control are made of fluorescent glow in the dark material to allow for easy use in dark rooms. On the remotes for the Denon amplifiers and DVD players, the important keys have been highlighted with the GLO-Key technology. Some of the remotes have also a backlight that illuminates the keys on touch of the remote.
HDMI (High Definition Multimedia Interface)
This is a digital interface standard for next generation television developed based on the DVI (Digital Visual Interface) used for computer displays and optimized for use in non-professional equipment. With it, non-compressed digital video and multi-channel audio signals can be transferred with a single connector, eliminating the need to use separate cables for picture and sound and making it possible to make connectors smaller. HDMI is compatible with HDCP (High-bandwidth Digital Contents Protection), a technology for protecting copyrights that encrypts digital video signals.
Made For iPod
The Made for iPod mark signifies that this product has been designed to work with iPod devices either through docking stations or connection cables. Available features will be dependant on the products used.
Multi-Room Entertainment System
Denons Multi Source function lets you select different audio sources for listening in different locations (some models may have volume adjust only for zone 2). Different sources can thus be enjoyed in the main room (MAIN) and sub-room(s) – ZONE 2, ZONE 3 or ZONE 4 – simultaneously (number of zones is model dependent). For additional information, check the instruction manual of the A/V receiver or power amplifier of interest for complete functionality.
