Inputs And Outputs Notes
Digital Signal Processing (DSP):
The Denon AVR-2105 is equipped with
a new high-resolution Analog Devices Hammerhead 32-bit floating DSP processor.
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.
receiver incorporates a wide variety of surround modes to bring you maximum
enjoyment from your audio and video software. The surround modes include:
- Dolby Digital
- Dolby Digital
- Dolby Pro Logic
- Dolby Pro Logic
- Dolby Pro Logic IIx
- Game (2-channel sources only)
- DTS Digital
- DTS-ES Extended
- DTS Neo:6
- DTS 96/24
- Denon Original Surround Modes (DSP)
- Rock Arena
- Jazz Club
- Mono Movie
- Video game
- 5CH/7CH Stereo
receiver has a personal memorization function that automatically memorizes the
surround modes and input modes selected for the different input sources. When
the input source is switched, the modes set for that source last time it was
used are automatically recalled. The surround parameters, tone control settings,
and playback level balance for the different output channels are memorized for
each surround mode.
Setting: When watching a DVD or other video source, the picture on the
monitor may seem delayed with respect to the sound. By inputting the distance
between the listening position and each speaker, the proper amount of delay is
applied to synchronize the sound with the picture. You can set the distance of
each speaker between 0 and 15 feet in 1-foot increments.
Cinema EQ: The Cinema EQ
function gently decreases the level of the extreme high frequencies,
compensating for the overly bright sounding motion picture soundtracks. You can
select this function when the front speakers sound too bright. This function
only works in the Dolby Pro Logic IIx, Dolby Digital, DTS Surround, and DTS
are two 2-channel playback modes exclusively for music:
- Direct: audio
signals bypass the tone control circuits, and are transmitted directly,
resulting in good quality sound.
allows you to adjust the tone to achieve the desired sound while watching
24-Bit, 192 kHz D/A
The AVR-2105 uses highly accurate Analog Devices 24-bit, 192 kHz Digital-to-Analog
converters on all 8 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.
The receiver is equipped with a new 7.1-channel Auto Setup function to
achieve the most ideal sound field for your room. With the supplied DM-S305
microphone placed at the listening position, the powerful new 32-bit floating
point DSP automatically and accurately analyzes, adjusts, and sets the speaker
configuration of the system. The microphone is a specially designed, high
performance unit with a heavy duty base that suppresses vibrations for accurate
Subwoofer Settings: When
"Large" is set for the front speakers, and "Yes" is set for the subwoofer in the
speaker setup, you can choose the following settings for the subwoofer channel:
- Subwoofer Mode: You can
select one of two modes:
- LFE Normal: subwoofer
plays the LFE channel signals (during playback of Dolby Digital and DTS
signals) and the low frequency signal range of the channels set to
"Small" in the speaker setup. Low frequencies for channels set to
"Large" are played from those channels only.
- LFE + Main: subwoofer
simultaneously plays the low frequency signal range of the channels set
to "Large" and the LFE channel signals. In this playback mode, the low
frequency range expands more uniformly through the room.
can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz,
100Hz, 120Hz, 150Hz, 200Hz or 250Hz.
Dual Source/Dual Zone Capability:
The AVR-2105 allows you to enjoy one source in your main listening room, while another source plays in a remote room. Depending on how you configure the receiver, using the dual zone capability of this receiver will require an amplifier and speakers, a set of powered speakers, or simply a set of non-powered speakers located in a remote location. If the receiver is set up for 7.1 surround operation, the Zone 2 RCA outputs act as fixed-level line outputs, and there are no Zone 2 amplified (speaker-level) outputs; in this configuration, the RCA line outputs must be connected to an amplifier or powered speakers equipped with a volume control. If the main room is configured for 5.1-channel surround, the Power Amp Assign function allows you to use the two Surround Back speaker outputs to power speakers in your remote listening room. When the Power Amp Assign function is active, the level of the Zone 2 speaker and preamp outputs can be controlled with the Zone 2 volume buttons on the remote.
Video Up Conversion:
The receiver's video transcoding technology converts composite and S-Video
signals to component video signals to output to the monitor. This allows you to
enjoy the highest picture quality from all video gear connected to the receiver.
In addition, composite video signals are up converted to S-Video and S-Video
signals are down converted to composite for connecting convenience.
HD Video Switching: The
unit has three assignable component video inputs and a high-performance relay
that is used to switch the signals. The switcher has an extended bandwidth range
of up to 100 MHz, making it compatible with progressive DVD (480p) and HDTV
formats (720p and 1080i).
AVR-2105 comes with a remote control which can
operate the receiver as well as other remote control capable Denon components. In addition, the remote is pre-programmed with control signals for other
brands of products, including cable boxes, CD players, TVs, Cassette decks,
Laserdisc, DBS, VCRs, CD recorders, Minidiscs, DVD players and DVD recorders.
And Outputs Notes
AVR-2105 features 3 optical digital (Toslink) inputs and 1 coaxial digital
input. Each input can be assigned to any of the different input sources except Phono,
Tuner and V.Aux (front panel). There is also one Optical
Digital outputs for use with a CD, MD or other digital recording device.
Multi-Channel External Input: The
AVR-2105 is equipped with a 5.1-channel input to accommodate present and future
multi-channel formats. These inputs are rated up to 100kHz for high resolution
audio sources such as SACD or DVD-Audio. You can set the playback level of the
analog input signal connected to the External Input terminal to +0dB, +5dB,
+10dB or +15dB.
Speaker Terminals: All of the receiver's speaker terminals are binding posts.
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
Room-to-Room Remote Jacks: The
receiver has a mini-jack input for use with an optional Denon
RC-616 IR re-transmitter. The adjacent room-to-room output is for future
Front Panel (V.Aux) Inputs: This
unit features stereo audio, composite video and S-Video, and an optical digital
input on the front panel for conveniently connecting a game console or
camcorder. The input for the DM-S305 microphone is also located on the front panel. These inputs are covered by a removable panel.
The receiver has a standard 1/4" headphone jack on the front panel for
private listening. When headphones are plugged in, the receiver's speaker and
preamp outputs are automatically turned off.
