Receiver Inputs and Outputs Notes
Speaker System Features
Digital Signal Processor: The
AVR-487 features a 32-bit DSP processor. This high-quality DSP chip gives the
receiver the ability to accurately decode surround and DSP modes.
24-bit, 96kHz D/A Converters:
The AVR-487 uses highly accurate 24-bit, 96kHz D/A converters to handle
digital-to-analog conversion, giving you superior sound quality.
Surround Modes: This
receiver incorporates a wide variety of surround modes to bring you maximum
enjoyment from your audio and video software. The surround modes include:

Neural Surround: Neural
Surround has been adopted by XM Satellite Radio for digital radio broadcasts of
XM HD Surround recordings and live events in surround sound. Neural Surround
employs psychoacoustic frequency domain processing which allows delivery of a
more detailed sound stage with superior channel separation and localization of
5-Channel Stereo: The
receiver's 5-channel stereo mode transforms any two-channel source into surround
mode, but without directional steering effects. The left front channel signals
are duplicated in the left surround channel, and the right channel signals are
duplicated in the right surround channel. All in-phase components of the left
and right channels are output from the center channel.
iPod Compatibility: Using the
optional Denon ASD-1R iPod dock (033ASD1RBK or 033ASD1RWT), you can connect your
iPod to the AVR-487. Folder and file names appear on the receiver's display
panel. The iPod can be controlled using the buttons on the main unit and the
remote control. iPod functions include: Play/pause, Stop, Manual search, Track
search, Repeat play (one or all tracks), and Shuffle play (songs or albums).
XM Satellite Ready: You can
listen to XM Satellite Radio by connecting the XM Mini Tuner and Mini Tuner Home
Dock to the AVR-487's proprietary plug. XM Satellite
Radio offers over 170 commercial-free channels of music, news, sports, comedy,
talk, and entertainment to choose from--all in digital quality. During XM
playback, you can display the channel number and name, category, artist name,
and song title on the front panel. Note: A subscription is required in
order to receive XM Satellite Radio.
5.1 Multi-Channel Input:
The AVR-487 is equipped with a
5.1-channel input to accommodate outboard decoders.
Assignable Digital Inputs: You
can assign the name of the component connected to each of the two digital
inputs. The names you can choose from include: CD, AUX, DVD, TV, VCR, V.AUX, CD-R, or
Personal Memory Plus:
The Personal Memory Plus function automatically memorizes the surround mode,
channel volume, surround parameters, and other settings for each of the separate
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, Dolby Pro Logic II, Dolby Digital,
DTS Surround, DTS Neo:6, and Neural Surround
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.
You can select one of the four settings: "Off", "Low",
"Mid" (middle), or "Hi" (high).
Last Function Memory:
This unit is equipped with a last function memory, which stores the input and
output setting conditions as they were immediately before the power was switched
The unit is also equipped with a back-up memory. This function provides
approximately one week of memory storage when the main unit's power switch is
off and with the power cord disconnected.

addition to controlling the AVR-487 receiver and other Denon A/V components, the
supplied remote is pre-programmed to control many brands of A/V components,
including DVD players, Video Disc players, VCRs, TVs, cable boxes, DBS
(satellite) receivers, CD players, CD Recorders, MiniDisc recorders, and tape
decks. The unique remote has controls on both sides: on the top, and under a
hinged panel on the back.
Receiver Inputs and Outputs Notes
Front Speaker Outputs: The
AVR-487 offers Front "A" and "B" speaker outputs, allowing
you to connect a second pair of speakers for another room. Because the
"A" and "B" speaker outputs are wired in parallel, the
minimum impedance is 6 ohms when using "A" or "B" and 12
ohms when using "A" and "B" speakers together.
Speaker Connectors: This
receiver is equipped with binding post connectors for the front left A, front
right A, front left B, front right B, surround left, surround right, and center speakers. They are not 5-way
binding posts because a plastic collar prevents their use with spade lugs and
they are positioned too far apart to be used with dual banana plugs.
Front Panel Inputs: The
receiver has a set of A/V inputs on the front panel behind a removable cover. It
includes left and right RCA audio jacks and an RCA composite video jack.
Headphone Jack: The
AVR-487 has a standard 1/4" headphone jack on the front panel. When headphones
are plugged into the headphone jack, the
speaker outputs are automatically turned off. When the plug is removed from the
headphone jack, the speakers automatically turn on again.
Video D/A Converter:
In order to output a high-quality digital signal with its original purity still
preserved, this unit employs a 10-bit, 108-MHz video D/A converter. This design
improves the reproducibility of extremely minute details so that the picture
viewed on the screen is completely faithful to the original image in both its
colors and high resolution.
Audio D/A Converter:
This unit has dual 192kHz/24-bit digital-to-analog converters.
Progressive Scan Output: This unit has a progressive scan output for a
sharper, noise-free picture with finer details. Video images are displayed with
optimum naturalness and color reproduction with less flicker and fewer motion
artifacts than traditional interlaced scanned pictures.
HDMI Output: The DVD-557 is
equipped with an HDMI (High Definition Multimedia Interface) connection, which
outputs both digital video and digital audio signals in one cable. The HDMI can
be set to output 480p, 720p, or 1080i signals to match the input capability of
the connected TV or monitor. This unit supports
HDCP encryption. Note: The AVR-487 receiver does not have HDMI
switching, so the HDMI cable should be directly connected to the TV.
2 MB Buffer
Memory: This unit is equipped with a 2
MB buffer memory to ensure that both picture and sound are played without
interruption when the DVD disc shifts from layer 1 to layer 2, or in the rare
event of a pickup dropout.
MP3/WMA Playback: This
unit will playback MP3 and WMA audio files recorded on a CD-R or CD-RW disc. When playing back
an MP3/WMA-encoded disc, you can directly access a track by entering the track
number on the numerical keypad on the remote.

pressed, that position is stored in the memory. When the Play button is pressed
after pressing the Stop button, playback resumes from the position where the
disc was stopped. MP3/WMA/JPEG playback will resume from the beginning of the
current track. The resume play memory function still works even if the power is
Dialog Speed: When playing back
a Dolby Digital-encoded disc, you can play the disc back in a slightly faster or
slower speed while keeping the sound quality as normal as possible. When Dialog
Speed is activated, you can select playback at 1.3x or 0.8 normal speed.
