Input and Output Notes
7-Channel Equal Power Amplifier: The Denon AVR-1609
features a 7-channel equal power, discrete amplifier. Each channel is rated at
75 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 in the main room, and the surround back channels can be
reassigned to power Zone 2 speakers at the same time.
Digital Signal Processing (DSP):
The Denon AVR-1609 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.
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-1609'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:
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:
all speakers except front left and right
- Audyssey Flat: optimize frequency response of all speakers
- 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.
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:
- Dolby Digital: Dolby
Digital is a 5.1 multi-channel digital surround format.

- Dolby Pro Logic II: Dolby Pro Logic II technology processes any high
quality stereo (two-channel) movie and music audio into five playback
channels of full-bandwidth surround sound. A matrix surround decoding
technology, Dolby Pro Logic II detects the directional cues that occur
naturally in stereo content and uses these elements to create a five-channel
surround sound playback experience. You can choose from Cinema, Music, or Game
formats. You can also choose Dolby Pro
Logic (the earlier 4-channel mode).
- Dolby Pro Logic IIx: Pro Logic IIx expands any existing
stereo- or 5.1-channel audio for a 6.1- or 7.1- channel playback, creating a
seamless, natural surround soundfield that immerses you in the entertainment
experience. You can choose from the following Dolby Pro Logic IIx formats -
Cinema, Music, or Game.
