Features
7-Channel Equal Power Amplifier: The Denon AVR-2309CI
features a 7-channel equal power, discrete amplifier. Each channel is rated at
100 watts RMS. The amp can power a 7.1-channel surround system in the main room;
or it can power a 5.1-channel system and the surround back channels can be
reassigned to power Zone 2 speakers at the same time.
Digital Signal Processing (DSP):
The Denon AVR-2309CI is equipped with a
high-resolution 32-bit floating point Digital Signal Processor (DSP). 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.
24-Bit, 192 kHz D/A
Converters: The AVR-2309CI uses Analog Devices 24-bit/192-kHz Digital-to-Analog
converters for all channels. The 192kHz sampling and
24-bit word length capabilities of the DACs allow you to play high-resolution
recordings and hear the increased clarity, detail and dynamic range of those
recordings.
Audyssey: This receiver is equipped with an Auto Setup and Room Equalization function, to
achieve the most ideal sound field for your room.
The AVR-2309CI's Audyssey MultiEQ
function is designed to optimize the sound quality at each listening position in
the room. The included DM-A409 microphone is used to measure test tones at each
listening position. This measured data is then analyzed using a program to
improve acoustic characteristics in the listening area. For best results at
least 6 positions should be measured, including a main position. The main
position is given more weight in the calculations.
Audyssey Settings:
- MultEQ:
The Room EQ function offers the following adjustments:
- Audyssey: optimizes the crossover point, output
level, delay time, and equalization of all speakers based on speaker
frequency response, speaker location, and room acoustics
- Audyssey Byp. L/R:
optimizes
all speakers except front left and right
- Audyssey Flat: optimize frequency response of all speakers
to flat
- Manual:
adjusts the tonal quality for each speaker individually using the manual equalizer
settings; adjust from -20 to +6 dB at 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 khz, 4 kHz, 8 kHz, and
16 kHz
- Off: turns equalizer off
- Dynamic EQ: Audio engineers mix music and movie
soundtracks at reference levels much louder than typical home listening
levels. At lower volumes the human ear perceives sound differently; voices
change, bass dissipates, and the surround effect becomes less enveloping.
Dynamic EQ adjusts the frequency response curve based on volume to maintain
consistent bass output, octave-to-octave balance, and surround impact,
resulting in rich sound at any volume.
- Dynamic Volume: Dynamic Volume addresses the issue of
commercials that are too loud and movie soundtracks with vast differences
between soft and loud passages; the results are more intelligible dialogue,
loud passages maintain impact, and soft whispers are clearly heard. When the
volume level changes, Dynamic EQ also adjusts the frequency response to
maintain sound quality.
Custom Integration: The AVR-2309CI carries
the "CI" stamp, which is Denon's certification to custom installers that the
receiver has advanced connectivity and control features often required for
custom home integration and theater applications using premium control systems.
These features include a RS232C jack for use with whole house control systems,
remote in/out IR command control, and a +12-volt trigger.
Video
Up-Conversion Powered With DCDi By Faroudja: The AVR-2309CI is equipped with a
flexible video switching system that converts video signals in an effort to only
require one video connection from the receiver to your TV. The video switching system
features a Directional Correlation De-interlacing (DCDi) special video processor
developed by Faroudja that involves advanced algorithms to remove the jagged
edges that appear when standard interlaced video is viewed on progressive scan
displays. DCDi 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. Unlike most other conversion
circuits, this receiver will 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/1080p input cannot be converted)
Note: Video signals
input as HDMI must be output via HDMI.
