Our take on the Denon AVP-A1HDCI

by Dave Bar
Denon

Denon's superbly crafted AVP-A1HDCI preamp/processor enhances your high-definition home theater experience with sophisticated features and extraordinary audio and video performance. You get advanced video switching, top-notch THX® Ultra2 processing, plus Dolby® True HD and DTS-HD™ Master Audio decoding to provide superior surround sound with compatible Blu-ray players and discs. Pair it with Denon's outstanding POA-A1HDCI multichannel power amplifier to enjoy reference-quality sound.

Outstanding picture quality from every video source
The 'A1HDCI will accept as many as six high-definition digital video signals at resolutions up to 1080p via its HDMI inputs. This lets you hook up high-res sources such as a Blu-ray Disc player, an HDTV tuner, and a high-end DVD player like Denon's DVD-5910CI, and easily switch among them. Two HDMI outputs mean you can route your high-def video signals to more than one HDTV or projector.

Denon also equipped the 'A1HDCI with the Silicon Optix Realta™ HQV chip — a state-of-the-art video processor usually found only in professional video equipment. It incorporates broadcast-quality video deinterlacing and 1080p scaling for improved detail and smoother playback from all of your video gear, whether connected via HDMI or analog inputs.

Wi-Fi® connectivity and HD Radio
This preamp/processor gives you convenient wireless access to digital music files and JPEG photos stored on your PC, using your Wi-Fi or Ethernet home computer network. It also lets you tap into the world of Internet radio via a broadband Internet connection. The built-in HD Radio tuner lets you listen to the free, over-the-air digital programming that many AM and FM stations now broadcast. Plus, you get front- and rear-panel USB ports to plug in a compatible MP3 player, hard disk drive, or USB flash drive loaded with your favorite tunes.

Precision auto setup tailors sound to your room
Denon also included Audyssey MultEQ® XT, a sophisticated auto-calibration system that helps you get the most accurate home theater sound possible. The 'A1HDCI uses the supplied microphone to analyze sound from up to eight different listening positions, then automatically adjusts level, equalization, and delay settings for each of your speakers. You get precise response across a wide listening area instead of just a single "sweet spot," so everyone in the room can enjoy balanced home theater sound. Audyssey's Dynamic EQ feature ensures that your surround sound stays rich and clear, even at lower volume levels.

Multi-room flexibility
This component's multi-source, multi-room output gives you flexible entertainment options throughout your home. You can enjoy a surround sound movie in your main room while a housemate watches a different video source in a second room, and another housemate listens to stereo music in a third. (External amplification required.) You can even route digital audio signals to a fourth room for playback with a receiver equipped with optical digital inputs.

Top-notch construction for detailed sound
The 'A1HDCI treats your digital sources right with high-quality Burr-Brown digital-to-analog converters for all channels. Pure Direct mode switches off the video circuits and display panel for greater sonic purity when listening to music. This preamp's rock-solid construction includes a massive anti-resonant chassis and twin toroidal transformers dedicated to the audio section only. Seven additional transformers supply power to each individual circuit block. This beefy build, along with shielded and isolated circuitry, ensures pristine audio and video performance at all times.

Features

Overview: The Denon AVP-A1HDCI AV Surround Sound and Video Processor sets the standard for both audio and video processing ability. Built with uncompromising attention to detail, the AVP-A1HDCI is equipped with an astonishing six individual power transformers to ensure the ultimate audio and video fidelity, eliminating interference between the various audio and video processing sections. Featuring unparalleled audio connectivity, the AVP-A1HDCI is equipped with 12 high definition video inputs (6 HDMI/6 component) and an additional 16 standard definition inputs, with deinterlacing, upscaling and conversion to HDMI outputs via the Silicon Optix HQV Realta reference video processor. In addition, the Denon AV Surround Control Center features state-of-the-art next-generation digital media connectivity with built-in Ethernet and Wi-Fi (802.11b/g) that lets you access music and photo files as well as Internet radio stations. An optional adapter lets you stream your favorite songs and videos from your iPod.

Note: The Denon AVP-A1HDCI is a preamplifier and requires and separate power amplifier such as the Denon POA-A1HDCI surround power amplifier.

Preamplifier Construction: The AVP-A1HDCI utilizes the following uncompromising construction techniques for the ultimate A/V experience:

  • Full separated Audio, Video, Pre-Amp and Power Supplies allow for a cleaner and clear signal path
  • Left and Right channel separated construction.
  • Aluminum diecast insulators
  • Direct Mechanical Ground to minimize mechanical vibration from transformer and radiators
  • All new circuit layouts that shorten audio and video signal paths for best picture and sound
  • Aluminum front and side panel
  • XLR and RCA 9.3 ch preout

High Current And Separated Power Supply: The AVP-A1HDCI features seven individual transformers to supply power to each discrete circuit. Its two toroidal transformers are only for audio with separated coil winding for pure audio playback. The unit's separate power supply also improves signal-to-noise ratio level.

DDSC HD-Digital (Dynamic Discrete Surround Circuit): The Denon AVP-A1HDCI is equipped with the latest technology in surround audio performance. All elements of the Surround Processor are optimized to the highest standards by the use of selected high performance and discrete components, particularly the A/D and D/A converters and the sophisticated DSP surround decoder. DDSC HD-Digital (Dynamic Discrete Surround Circuit) features triple Analog Device Hammerhead SHARC 32-bit floating point DSP processors, Burr-Brown audio DACs in double differential mode (4 per audio channels) on all 12 output channels, and a master clock design for more accurate processing and less jitter noise.

24-Bit, 192 kHz D/A Converters: The AVP-A1HDCI uses highly accurate Burr Brown PCM-1791 Digital-to-Analog converters, for each channel, on all 12 output channels. The 192kHz sampling and 24-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

Advanced AL24 Multi-Channel Processing: Denon's Advanced AL24 Multi-Channel Processing technology dramatically improves information volume in the time axis region using high-speed signal detection and processing technology. In addition to expanding to expanding original 16-bit data to 24 bits, Advanced AL24 Processing uses data interpolation along the time axis or upconverted sampling to achieve natural interpolation without losing the original data. A digital filter is used to further expand adaptability and perform optimum filtering calculations for ringing-free pulse response, pulsive music data and attack sounds. The result is reproduction of such spatial information as the delicate nuances in your music, the positions of the performers, and the breadth, height, and depth of the concert hall. Advance AL24 Processing is conducted for all channels and modes other than the DSD Direct mode.

Custom Integration: The AVP-A1HDCI carries the "CI" stamp, which is Denon's certification to custom installers that the preamplifier has advanced connectivity and control features often required for custom home integration and theater applications using premium control systems. These features include RS232C jacks for use with whole house control systems, remote in/out IR command control, and assignable +12-volt triggers.

Full 10-Bit Processing Video Circuit With Up-Conversion: The AVP-A1HDCI features discrete construction and circuitry for the highest quality video processing. The preamplifier utilizes a Realta sxT2 HQV 10-bit processor for i/p and video scaling. The AVP-A1HDCI's flexible video switching system converts video signals in an effort to only require one video connection from preamplifier to TV. The video switching system features Multi-Cadence Detection for accurate i/p conversion when standard interlaced video is viewed on progressive scan displays. The Realta sxT2 HQV 10-bit processor converts standard interlaced signals into progressive scan signals in order to eliminate the stair-casing effect that conventional up-converters can introduce to diagonal edges. In addition, this unit's Full 10-bit video processor can pass a 1080p/24fps signal through its HDMI input/output and supports Deep Color up to 36-bit and xvYCC broader color spacing via HDMI. Unlike most other video conversion circuits, this preamplifier will also convert analog signals from composite video, S-Video, and component video to HDMI up to 1080p:

  • Composite Video: can be converted to S-Video, component video, or HDMI
  • S-Video: can be converted to composite video, component video, or HDMI
  • Component Video: can be converted to composite video, S-Video, or HDMI (480i signals only when down converting)
  • HDMI: HDMI input signals must be output as HDMI

Noise Shaped Video (NSV): The NSV precision video feature works in the digital domain to reduce noise in the video signal frequency band in order to enhance video signal linearity, provide accurate signal representations, and enhance the picture quality. Noise shaping techniques can be combined with dynamic element matching techniques in order to reduce the matching requirements of DAC elements by converting the analog mismatch into  and out of band noise. This approach of dynamic element matching and noise shaping has been shown to allow the use of sigma delta modulation at video data rates. NSV can achieve ultimate precision with 12-bit/216-MHz fidelity in both digital-to-analog and analog-to-digital domains.

HDCD Decoding: The AVP-A1HDCI automatically detects and decodes the digital bitstream from a CD that has been encoded through the special High Definition Compatible Digital (HDCD) process. HDCD discs use 20-bit encoding and other proprietary processing to provide the ultimate in CD listening.

THX Ultra2 Certification: This unit has been built and tested to conform to the high standards of sound and build quality set by the THX Ultra2 Certification program. THX is the unique collaboration between Lucasfilm Ltd. and audio equipment manufacturers. THX Ultra2 certification provides a rigorous set of performance standards, along with proprietary surround sound post-processing technologies, designed to enhance the surround sound playback experience in the home theater. When the THX Ultra2 mode is on, the following THX post-processing is added:

  • Re-Equalization: The tonal balance of a film soundtrack tends to be excessively bright and harsh when played back over audio equipment in the home because film soundtracks are designed to be played back in large movie theaters using very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie soundtrack in a typical home environment.
  • Timbre Matching: The human ear changes our perception of a sound depending on the direction from which the sound is coming. In a movie theater, there is an array of surround speakers so that the surround information is all around you. In a home theater only two or four surround speakers are used. The Timbre Matching feature filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.
  • Adaptive Decorrelation: In a movie theater, a large number of surround speakers help create an enveloping surround sound experience, while in a home theater there are usually only two or four surround speakers. This can make the surround speakers sound like headphones that lack spaciousness. The surround sounds will also collapse into the closest speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time and phase relationship with respect to the others. This expands the listening position and creates the same spacious surround experience as in a movie theater.
  • ASA (Advanced Speaker Array): ASA is a proprietary THX technology which processes the sound fed to the two side and two back surround speakers to provide the optimal surround sound experience.
  • BGC (Boundary Gain Compensation): The BGC feature provides overall improved bass balance of your home theater system by compensating for room and wall boundaries.

Surround Formats: This preamplifier incorporates a wide variety of surround formats to bring you maximum enjoyment from your audio and video software. The supported surround formats include:

  • Home THX Cinema: Home THX Cinema accurately translates the sound from the movie theater environment into the your home by correcting the tonal and spatial errors that occur. When the Home THX Cinema mode is selected on the AVP-A1HDCI, THX post-processing is automatically added after the Dolby Pro Logic, Dolby Digital or DTS decoder.
  • THX Ultra2 Cinema Mode: The AVP-A1HDCI is equipped with THX Ultra2 Cinema mode that plays 5.1 channel movies using up to 12 speakers (9.3). The THX processing blends the surround and surround back speakers providing the optimal mix of ambient and directional surround sounds. DTS-ES and Dolby Digital EX 6.1 channel soundtracks are automatically detected and processed appropriately.
  • THX Surround EX: With the AVP-A1HDCI Dolby Digital EX soundtracks further undergo Home THX Cinema processing to achieve a THX Surround EX system. This mode gives you more detailed imaging behind you, allowing for 360-degree surround sound effects.

  • Direct: audio signals bypass the tone control circuits, and are transmitted directly, resulting in good quality sound
  • Stereo: allows you to adjust the tone to achieve the desired sound

Surround Parameters: You can adjust the following surround mode parameters:

  • CINEMA EQ (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Pro Logic (including PL II and PL IIx), Dolby Digital, DTS Surround, DTS Neo:6, and Wide Screen modes.
  • D.COMP (Dynamic Range Compression): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). This only works when playing program sources recorded in Dolby Digital or DTS. You can select one of the four settings: "OFF", "LOW", "MID" (middle), or "HI" (high).
  • LFE: This setting adjusts the low-frequency effects level (LFE). You can adjust the LFE from -10 to 0 dB.
  • Center Image: This function assigns a center channel signal to the front left and right channels for wider sound. You can adjust the center image range from 0.0 to 0.3 to 1.0.

This measured data is then analyzed using a program to improve acoustic characteristics in the listening area. For best results at least 8 positions should be measured, including a main position. The main position is given more weight in the calculations. The Audyssey function adjusts the following measurements automatically: Speaker Configuration, Distance, Channel Level, Crossover Frequency, and Room EQ. The preamplifier also features a Pro Auto Setup which allows a professional installer to measure up to 32 positions using software and equipment exclusively purchased from Denon.

  • Room EQ: The Room EQ function offers the following adjustment settings:
  • Audyssey: adjusts the frequency response of all speakers to correct the effects of room acoustics
  • Audyssey Byp. L/R: optimizes frequency response of speakers except front speakers to match room acoustics
  • Flat: frequency response of all speakers are flat
  • Manual EQ: This feature adjusts the tonal quality for each speaker using the preamplifier's built-in graphic equalizer. You can select -20 to +6 dB for the following frequencies for each speaker - 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2khz, 4kHz, 8kHz, and 16kHz.
  • Off: Turns off EQ

Subwoofer Control: The preamplifier features three subwoofer preamp outputs. You can choose to connect one, two or  three powered subwoofers. You can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz, 90Hz, 100Hz, 110Hz, 120Hz, 150Hz, 200Hz or 250Hz. You can also select the subwoofer output level between 0, 5, 10 or 15 dB. In addition, the preamplifier features a THX Ultra2 Subwoofer mode when connecting a powered subwoofer compatible with THX Ultra2 standards or a subwoofer that can be properly played at low range.

Preamplifier Assign: There are 9.3ch preamplifier channels built into the AVP-A1HDCI. The preamplifier features nine different preamplifier assignment configurations. You can choose from the following - 9.1ch, 9.2ch, 9.3ch, 7.1ch, 7.2ch, 7.3ch, 5.1ch, 5.2ch, or 5.3ch.

Dual Surround Speaker Mode: The AVP-A1HDCI provides the ability to connect two different sets of surround speakers to the Denon POA-A1HDCI amplifier, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise. If you play one pair of surround speakers at a time (Surround A or B), the minimum impedance of the connected speakers is 4 ohms. If you play both pairs of speakers simultaneously (Surround A + B), the minimum impedance of the connected speakers is 8 ohms. In addition, the preamplifier also features discrete surround back left/right channels. 

Multi Zone/Multi Source Operation: Denon's Multi-Zone/Multi-Source function lets you select different audio/video sources for listening and viewing in different locations of your home. The AVP-A1HDCI features a Main Zone (Zone 1), two Audio/Video Zones (Zone 2 and 3), and a Digital Audio Only Zone (Zone 4). The Main Zone 1 contains 9.3-channel playback of your audio/video gear in your main entertainment room. The Audio/Video Zone 2 allows stereo or digital audio and video playback of another AV source connected to the preamplifier and power amplifier in another room of your home via left/right RCA audio output connections or optical digital output connection and composite video, S-video or component video connectors. Zone 2 will pass S-Video and composite video inputs through its composite video output. The S-video and component video output of Zone 2 will only output video that is input using the same type of connection. Audio/Video Zone 3 also allows stereo audio and video playback of another AV source connected to the preamplifier in another room of your home via left/right RCA audio output connections  and a composite video connector. Zone 3's composite video output will support video input via S-video or composite video. The Digital Audio Only Zone 4 allows you to play a digital audio source connected to the preamplifier in a fourth room of your home via an optical output connection.

AM/FM Tuner With RDS: The preamplifier features an AM/FM tuner which allows you to preset up to 56 radio stations (8 stations each in 7 separate banks). You can delete any unused tuner banks. The unit also supports RDS (Radio Data System). RDS is an FM broadcasting service which allows a station to send additional information along with the regular radio program signal. The following three types of RDS information can be received by this preamplifier's FM tuner - Program Type (identifies the type of RDS program), Traffic Program (identifies programs that carry traffic announcements), Radio Text (allows RDS stations to send text messages that appear on the display of the unit).

HD Radio: The AVP-A1HDCI features a separate, built-in HD AM/FM tuner. HD radio stations offer higher sound quality than conventional FM/AM broadcasts. HD FM stations sound as great as CD quality while HD AM sounds a rich as analog FM stereo. It is also possible to receive data services and select broadcasts from among up to eight multicast programs.

XM Satellite Ready: The optional XM Direct 2 Home Tuner (220XHD2H1, sold separately) lets you enjoy XM Satellite Radio through the XM-ready receiver. Simply connect the XM direct 2 Home Tuner to the XM jack on back of the receiver, place and aim the included antenna for optimum reception, and you are ready to start enjoying commercial-free music, plus live sports, new, talk, and exclusive entertainment. The channel number, channel name, artist name, and song title are listed on the AVR-4310CI's display and on the connected TV monitor. XM stations are stored as presets and recalled in the same way AM and FM stations are.

Note: In addition to the XM Direct 2 Home Tuner and the XM-ready receiver, you will need a subscription to XM Satellite Radio to receive XM programming.

USB Terminals:  USB terminals that let you connect a USB-compatible portable music player are located behind the fold-down door on the front panel and on the preamplifier's rear panel. You can connect your player or PC to these terminals and play the MP3 or WMA (Windows Media) files directly through your AVP-A1HDCIsystem. When an MP3 music file includes album art data, the album art can be displayed on your connected TV while playing the file. You can also play JPEG still picture files in a slideshow fashion that are stored on a USB memory device. The AVP-A1HDCIis compatible with mass storage class and MTP (Media Transfer Protocol) USB memory devices in FAT16 or FAT32 format.

Note: You cannot use the front USB port and rear USB port at the same time. You must select which port you want to use - Front or Rear.

iPod Compatibility: Using the optional Denon ASD-1R iPod dock (033ASD1RBK or 033ASD1RWT), you can connect your iPod to the AVP-A1HDCI Folder and file names appear on the preamplifier's display panel. The iPod can be controlled using the buttons on the main unit and the remote control. In addition, you can view photo and video data stored on an iPod on a TV or monitor. The AVP-A1HDCI also supports Denon's optional iPod/Network adapter docks (ASD-3N/ASD-3W, sold separately) through its iPod terminal.

Note: The ASD-1R and ASD-3N/ASD-3W is compatible with 3rd generation and later iPods with a dock connecter.

Home Network Function: The AVP-A1HDCI is equipped with an Ethernet port and WiFi (WLAN) antenna that lets you build various types of network environments either hardwire or wireless (802.11 b/g). You can use these network environments to take advantage of 4 home audio network functions:

  • Music Server: The AVP-A1HDCI's Music Server function lets you stream audio and still image files (MP3/WMA/WAV/MPEG-4 AAC/FLAC/JPEG) stored on your PC to the preamplifier. This network connection uses 2 standard technologies: Windows Media Player Network Sharing Service or Windows Media DRM10. To access iTunes library and playlists you need to install TwonkyMedia software to your PC. Twonky Vision is a software program needed to manage your iTunes database and can be downloaded from www.twonkyvision.com for a one time fee of $29.99. The AVP-A1HDCI also supports MP3 ID3-Tag (ver.2) and WMA META tags. The AVP-A1HDCI only supports files that are not copyright protected.
  • Internet Radio: Internet Radio is a system that lets you hear radio broadcasts from stations on the Internet. A wide variety of stations, both large and small and some which are operated by individuals, can be found on the Internet. Until now, radio stations could only be heard if you were within listening range of their radio waves, but with Internet Radio, you can listen to broadcasts from all over the world. The list of stations that the AVP-A1HDCI uses comes from the vTuner radio station database that has been customized for Denon.
  • Rhapsody: Rhapsody is a paid music broadcast service of RealNetworks which offers a massive music catalog. Rhapsody currently offers a 30-day free trial and memberships start at just $12.99 month.
  • A/V preamplifier Network Setup (Web control): This function lets you set up and control the A/V preamplifier over a network using Internet Explorer on a PC. The AVP-A1HDCI's Ethernet port also supports serial controls that use Crestron and others.
