Denon AVR5308CI Reference-Level 7.1-Channel Multi-zone Network Streaming AV Receiver




Product Description
From the ManufacturerDenon has long been one of the elite names in home theater receivers, offering a combination of advanced technologies and user-friendly features that transform even the most mundane listening rooms into rich, powerful audio environments. Now Denon sets the reference standard for sound and video quality with the AVR-5308CI A/V receiver, which is packed with all the latest technologies to produce the ultimate home theater experience. In addition to the many standard features people have come to expect from Denon receivers, the company adds such forward-looking details as THX Ultra2 certification; Denon's legendary DDSC-HD surround sound decoding with no less than three high-speed DSP processors; HDMI v1.3a digital video inputs that bring with them the latest high-definition audio formats, including Dolby Digital Plus, Dolby True HD, and DTS-HD Master Audio; and video upconversion all the way up to 1080p via the top-performing Realta HQV video processor. And that's just the tip of the iceberg, as the AVR-5308CI also offers versatile multizone functionality, including independent high-definition and standard-definition outputs, and network connectivity through your Ethernet or Wi-Fi network.
Under the Hood: Component Technology
With a power output of 150 watts per channel, the AVR-5308CI multizone 7.1 receiver can handle most audio applications.The AVR-5308CI offers a power output of 150 watts per channel, but adds a number of engineering advancements to get the most out of the technology. One of the most significant--7-Channel Equal Power--lets you connect seven speakers independently without connecting individual power amps via pre-outs. That's because the AVR-5308CI comes with a built-in internal amplifier for each speaker in your collection, along with five individual transformers that supply power to each discrete circuit. The all-new circuit layouts, meanwhile, shorten the audio and video signal paths to produce the best possible picture and sound. Finally, the receiver's Dynamic Discrete Surround Circuit (DDSC) optimizes all the elements of the three 32-bit floating-point digital sound processors through the use of discrete high-performance components, including separate Burr-Brown audio digital-to-analog converters on all output channels.
The receiver also offers a series of escalating AL24 Processing enhancements. Denon's original AL24 Processing technology was designed to faithfully duplicate some of the delicate nuances of analog music in digital form, a technology that's particularly effective among next-generation media with ultra-high bit and sampling rates. The results sound particularly good when music quietly fades away or starts again following silence, helping the listener detect some of the low-level details. AL24 Processing Plus upped the ante by supporting the 192 kHz sampling frequency of DVD-Audio. Denon followed with Advanced AL24 DSP and AL24 Multi Processing, which further increased the dynamic range and spatial information among high-resolution stereo PCM and multichannel sources.
The receiver also includes High-Definition-Compatible Digital (HDCD), an encoding/decoding technology that encodes with 20 bits of real musical information--as compared with 16 bits for all other CDs--thereby greatly reducing distortion. This creates a better dynamic range, a more-focused three-dimensional soundstage, and extremely natural vocal and musical timbres. And from a video perspective, the AVR-5308CI offers several valuable essentials: progressive scan technology, which processes approximately twice as much video data to produce a sharper, noise-free image with finer details; DCDi video processing, which employs advanced algorithms to remove the jagged edges that appear when standard interlaced video is viewed on progressive scan displays; and 10-bit Realta HQV video processing, which accurately upconverts video signals up to 1080p resolution while also offering Deep Color support and multi-cadence detection.
Diverse Sound ModesAs with the best surround receivers, the AVR-5308CI is capable of reproducing a host of 5.1-, 6.1-, and 7.1-channel audio formats, with several processing technologies layered over the top. In addition to providing standard Dolby Digital, DTS, and Pro Logic II formats, the receiver also supports Pro Logic IIx, which allows 5.1-channel sources to be played in up to 7.1 channels; the expanded multichannel capabilities of DTS 96/24, Neo:6 Surround, and DTS-ES Extended Surround, all of which improve the digital surround impression for 5.1 or 6.1 channels; and dts-HD and Dolby True HD, which boost the maximum sampling frequency (up to 96 kHz) and faithfully reproduce the sound of the studio master on up to 7.1 channels.
To assist with film soundtracks, the receiver offers a Cinema Equalizer that corrects for the placement of your speakers vs. the way they're placed in the movie theater. Theaters that locate their front speakers behind the movie screen tend to emphasize the high frequencies, which can sound too strong in a home with a conventional surround setup. Denon amplifiers adjust the high-frequency range so that the sound is cleaner and easier to listen to than uncorrected audio. Listeners can also improve the image detail of their audio sources using Neural Surround technology. This audio breakthrough--which is 100-percent compatible with stereo--offers superior spectral resolution and channel separation, thereby drawing the brain's attention to the sonic details in musical instruments, vocals, and ambience that are typically masked by other playback systems. This allows the listener to fully experience the richness and subtleties in recorded performance as never before. Neural Surround is the chosen format for XM satellite radio's XM HD surround programming.
Perhaps the most significant audio enhancement, however, is the receiver's THX Ultra2 certification. The THX Ultra2 Cinema mode produces the appropriate sound field effects when 5.1-channel movie sources are played in a 7.1 system, helping accurately re-create a theater-type sound in a conventional home listening environment. The AVR-5308CI works by widening the rear soundstage, which effectively makes the side speakers play ambient sounds and the surround back speakers play directional sounds. There's no better way to immerse your ears in a rich, powerful, nuanced surround sound environment. Likewise, the THX Ultra2 Music mode produces appropriate sound field effects for Dolby Digital, DTS, and other 5.1-channel music sources when played in a 7.1-channel system.
Convenience Features
The AVR-5308CI offers 6 HDMI inputs, 2 HDMI outputs, and a host of other connectivity options.Modern A/V receivers are increasingly designed for multi-room listening, and the AVR-5308CI is no exception. The four-zone, multisource system--which supports three analog and one digital source--lets you select different audio sources for listening in different locations, letting you simultaneously listen to the DVD player in the main room, the iPod in the bedroom, and XM radio in the kitchen, for example. The receiver also supports such multizone extras as a Zone 2 onscreen display, which lets you view the playback details of a second audio source through your TV; dual HDMI outputs for connecting to multiple TVs; an independent Zone 2 component output; and both digital-to-analog and analog-to-digital conversion for multizone output.
The AVR-5308CI is also capable of connecting to your PC's wired or wireless network via its built-in Ethernet and Wi-Fi connectivity. This lets you play back the MP3, WMA, AAC, FLAC, or WAV files stored on your computer's hard drive, access Internet radio stations, or play back JPEG photo slideshows. To make iPod playback easier, you can connect the receiver to Denon's separately sold ASD-1R iPod docking station, which charges and controls your iPod through the receiver's display.
Other user-friendly features include an EL touchpanel remote control, which offers an electroluminescent display similar to the technology employed by LCD backlights; built-in HD Radio; XM satellite radio compatibility (requires a subscription and an optional plug-and-play XM antenna); two-way remote capability; an attractive GUI with an onscreen display; and a night mode for neighbor-friendly listening.
Connectivity and SetupThe AVR-5308CI offers a host of inputs and outputs for connecting to diverse audio and video sources. The most significant is HDMI v1.3a, the digital interface standard for next-generation TV. With the receiver's six HDMI inputs and two HDMI monitor outputs, you can easily connect to such devices as HDTVs, DVD players, video game consoles, and cable and satellite boxes, each through a single cable that handles both high-definition video and multichannel audio signals. HDMI is also compatible with High-bandwidth Digital Contents Protection (HDCP), a technology for protecting copyrights that encrypts digital video signals. If your components don't offer HDMI outputs, you still have plenty of options, however, as the receiver also offers six component inputs, eight S-video and eight composite inputs, 11 total digital audio inputs (five optical, four coaxial, and two coaxial BNC), an Ethernet port, and two USB ports, among many others.
Audiophiles will dig the Denon Link jack, which is far less susceptible to radiated noise than coaxial or unbalanced cables. The Denon Link interface can transfer high-grade LPCM 24-bit, 192 kHz two-channel and 96 kHz, 24-bit multichannel digital output. The receiver also lets you input multichannel audio signals, whether in high-definition MUSE 3-1, SACD, or DVD-Audio formats, via the eight-channel input. Made using eight standard RCA cables--one each for front left, front right, center, surround left, surround right, surround back left, surround back right, and subwoofer--the eight-channel input receives discrete analog audio signals via a digital source such as a DVD player, creating an immersive multichannel audio performance.
Setting up the AVR-5308CI is easier than ever thanks to Denon's Audyssey technologies. Audyssey Equalized was the first technology to properly measure sound information throughout a listening area, and then combine the information to accurately represent the acoustic problems in the room. Based on these measurements, Audyssey calculates an equalization solution that corrects for both time and frequency response problems. Denon also employs Audyssey MultEQ XT technology, which automatically determines how many loudspeakers are connected, whether they are connected in phase, and whether they are satellites or subwoofers. After processing, it then analyzes all the physical details--speaker level, size, and distance--and determines the correct frequency response for up to eight listener positions simultaneously. It's a must for people who want to get the most out of their surround systems.

Yamaha RX-Z11BL 11.2-Channel Digital Home Theater Receiver


From the ManufacturerYamaha introduces a new benchmark for home theater receiver performance: the RX-Z11. This takes high end receiver evolution to a higher level with an enormous range of exciting features, capabilities and new cutting edge technologies. The RX-Z11 performance sets a new standard in home theater experience.Trilateral Sound DevelopmentYamaha set ambitious goals for the sound performance of the RX-Z11, and succeeded in achieving them through a trilateral sound development program. The three aspects of the program were technology, engineering and artistic sensitivity. Technology refers to the technologies that enable us to create the level of sound quality suitable for total audio enjoyment in the present digital audio era. Engineering refers to upgrading functions and specifications, which are the foundation of the overall quality. And of equal or perhaps even greater importance is artistic sensitivity, which is how we go beyond the specifications to create, tune and refine the sound based on the musical acuteness of our most experienced audio technicians. The result is that the RX-Z11 achieves an unprecedented level of audio performance. Sound that is not only clear and high resolution, but finely textured. Able, for example, to realistically convey the sound of light rain, rustling cloth or breaking glass. Surround sound that is not only spacious but has a sense of magnificence. Sound that is not only well localized, but sharply focused in every area of the immense CINEMA DSP HD3 sound field. And finally, sound with an optimum balance among the three key elements of resonance, deep bass and responsiveness, for best compatibility with all types of sources.
11.2-channel surround means absolute sound immersion11.2-Channel High Density Surround SoundThe RX-Z11 delivers 140W x 7 channels plus 50W to the four presence and rear presence channels. It also allows the simultaneous use of two subwoofers (hence 11.2 channels). In addition to Yamaha’s latest CINEMA DSP HD3 technology for high density, incredibly detailed surround sound, it provides extensive zone customization functions, enabling the 11 amp channels to be allocated to zones 2, 3 and 4 in various configurations.Digital ToP-ART and High Current AmplificationYamaha’s Digital ToPART design concept ensures that the receiver is fully capable of handling the transmission of high volume digital sound data at speeds up to 192kHz. The interior layout thoroughly isolates the digital, analog and video sections and provides the shortest possible signal routes. To achieve the quality demanded by the latest lossless compression formats received via HDMI bitstream transmission, circuit board designs were radically revised and parts selection was reevaluated. The RX-Z11’s superior parts include Burr-Brown DSD1796 DACs, an op amp, custom-made 27,000µF block capacitors and Schottky barrier diodes. A Variable Volume Control helps provide the best possible S/N ratio. High Current Amplification circuitry achieves high current power with low impedance for superior amplifier performance.The power amplifier uses current rather than voltage for feedback in all channels. Because there is virtually no phase shift, phase compensation can be kept to a minimum. This contributes to the RX-Z11’s excellent transient response, allows frequency response to remain unchanged even when the gain changes, and creates a warmer, texture-rich sound.HDMI 1.3a CompatibilityThe RX-Z11 is compatible with the newest version of the HDMI standard, 1.3a, providing the benefits of Deep Color (30/36bit) and the xvYCC color standard. Digital video and audio signals can be transmitted via a single HDMI cable and it accepts the lossless audio formats DolbyTrueHD and DTS Master Audio. There are five HDMI inputs, one of which is on the front panel, as well as two HDMI outputs that allow images to be simultaneously displayed from two devices, such as a flat panel monitor and aprojector. HDMI 1.3a means the RX-Z11 can handle the high 1080p/24Hz resolution of Blu-ray Discs, and also provides an Auto Lip-Sync function that automatically adjusts the lag between video and audio and a double speed Refresh Rate of 120Hz.Network Receiver CapabilitiesLike other Yamaha network receivers, the RX-Z11 can be connected to a PC or Yamaha MCX-2000, and can access Internet Radio via a LAN. It also has an HD Radio tuner and can display HD Radio information on the front panel or on a monitor. Two USB ports are provided, on the front and rear, with 500mA power support. It is compatible with PlaysForSure devices, Windows Vista, Yamaha Music CAST and various audio Codecs such as MP3, WMA, WAV and MPEG4 AAC. And the Compressed Music Enhancer restores the sound of the original music from digitally compressed formats such as MP3. The RX-Z11 offers an improved version that processes multi-channel signals with a DSP algorithm, so all channels (rather than just two) are enhanced, for more accurate reproduction and a more expansive sound.Advanced YPAO Sound OptimizationYamaha’s YPAO Sound Optimization system analyzes the room acoustics and various system factors, then makes adjustments to provide optimum sound quality. In addition to the previous adjustments for speaker size, distance and wiring, plus equalization and level, this Advanced YPAO has four new capabilities. The first is measurement at multiple locations (up to eight). It does not average the results but performs analysis weighted in accordance with the state of each location to calculate compensation values. This results in a larger "sweet spot" at the listening position. The second is the use of parametric equalization to cancel the effects of standing waves, which degrade bass response. The third is speaker angle measurements to optimize CINEMA DSP effects. And the fourth is an Easy Starter feature that activates YPAO when the microphone is inserted and the Enter button is pressed, with information shown on the display.Super-Versatile Zone ControlThe RX-Z11 has extensive zone control capabilities, which are too numerous to explain here. The most important point is that the 11.2 channels can be assigned in a wide variety of configurations to four zones. The presence, rear presence and extra (by surround back amp) speaker terminals can be assigned to each zone. It provides Intelligent Power Amplifier Assignability (surround back amp assignment) and Independent Zone Amplifier Assignment with 7.2-channel main zone playback. Also important is that Zone 2 can distribute bitstream signals and also offers component video output that up converts composite and S-Video signals. Some other convenient zone functions include: a Party Mode that permits audio of the same input source in the main room to sync with and other three zones with one-button operation, a Zone OSD function that lets you browse information about the songs or AM/FM/XM/HD radio broadcasts that are playing, Zone Mono that provides compatibility with one-speaker or three-speaker installation environments, and a Preamplifier Mode that permits the entire 11-channel amplifier to be allotted for three-zone use (main zone powered by an external amp).
