Equal Power Amp Design: The Denon AVR-1612 is equipped with
a 5 channel power amplifier rated at 75-watts (into 8-ohms, at 20-20kHz, with
0.08% THD, driving 2 channels) that reproduces high-fidelity sound in surround
mode with equal quality and power for all channels, true to the original sound.
The power amplifier circuit adopts a discrete-circuit configuration that
achieves high-quality surround sound reproduction. To faithfully reproduce the
original surround sound, each of the Denon AVR-1612's five channels are equipped
with its own high-current power amp of equal power. Since these power amps also
use discrete circuits configured with parts strictly selected for their
contribution to high sound quality, rather than with low-cost integrated
circuits (ICs), the surround sound playback is of impeccably high quality.
Minimum Signal Path Design: The simple & straight design
concept has been thoroughly implemented in the signal paths to contribute to clean
audio and video playback. Signal paths are as short as possible to keep signal
degradation in the audio and video circuitry to a minimum.
Direct Mechanical Ground Construction: Vibration-resistant
construction has been used to suppress the adverse influences of vibration on
sound quality. The power transformers, a source of vibration, have been securely
mounted on the high rigid bottom chassis. Direct mounting of cast-iron feet to
the radiator in near proximity to each other serves to suppress mutual vibration
with the power transformers and other sources of vibration.
Independent Power Supplies: The Denon AVR-1612 employs
independent stable power supplies
for high-quality sound and picture playback.
24-bit/192-kHz DACs: This receiver is equipped with
AKM Semiconductor 24-bit/192-kHz (AK4358VQ) DACs to decode and playback
high-resolution recordings with less jitter and clearer sound.
32-Bit Processing DSP: The Denon AVR1612 is equipped with a
HammerHead SHARC 32-bit DSP (ADSP21487) for powerful and highly accurate
surround sound reproduction.
High-Definition Audio Support: Fully compatible with current HD audio
formats, the Denon AVR-1612 A/V Receiver provides powerful, theater-quality
surround sound. The Denon AVR-1612 features support for Blu-ray high-resolution
audio formats, including Dolby TrueHD and DTS-HD Master Audio for a dynamic
surround-sound listening experience. These formats play back sound with
exceptional fidelity, providing a more realistic listening experience.
Surround Formats: This receiver incorporates a wide variety of
surround modes to bring you maximum enjoyment from your audio and video software.
The unit can be set to store the most recently selected surround mode for each
input, so it is automatically activated each time the particular input is chosen.
The surround modes include:
this mode the audio signal is played in its original form, without

Note: Dolby Digital and DTS listening modes can only be
selected if your audio source is connected to the AV receiver via a digital
audio connection (HDMI, optical or coaxial). Even though the AV receiver
will decode 7.1channel surround sound (via HDMI), it will only output 5.1ch
surround, because it lacks Surround Back channel speaker outputs (unless you
connect an addition Surround Back amplifier to the receiver's SB/FH Pre-Outs).
Pro Logic IIz requires additional Front-Height speakers connected to a
separate amplifier using the receiver's Surround Back/Front-Height preamp
Surround Parameters: You can adjust the following surround
- Dolby Pro Logic II Music Settings: While listening in the
Dolby Pro Logic II Music format, there are three further enhancements you can

there is limited output from the surround channels, panorama can be turned
on/off in the menu.
- Dimension: Allows you to move the sound field forward
- Center Width: Allows you to adjust the width of the
- Center Image: In the Neo:6 Music mode, the Center Image
feature adjusts the output of the left and right channels relative to the center
channel, allowing you to make the center channel more or less dominant as
needed. This improves the image of the center channel, especially when the
listener is off-center. Adjustment varies from 5 (nothing subtracted from the
L/R channels) to 0 (L/R channel output is cut in half).
- Denon Original Surround Mode Settings: While listening in one of
the Denon Original Surround Modes, there are three further enhancements you can
- Room Size: This feature allows you to set the size
of your desired acoustic environment when using specific Denon Original
Surround Modes; select Small, Medium small, Medium, Medium large, or
- Effect Level: This function adjusts the effect
signal level from 1 to 15 when using specific Denon Original Surround
- Delay Time: This feature adjusts the delay time
(0-300ms) to control the sound stage size
- Height Gain: Adjust the volume (Low/Mid/High) of the Front Height
channels in Dolby Pro Logic IIz.
Audyssey MultEQ: Audyssey MultEQ technology helps create an
optimal acoustic profile for your home theater. Using the included setup
microphone, Audyssey MultEQ measures sound levels and adjusts speaker
configuration accordingly, making setup fast and easy. This room acoustic
measuring and correction system analyzes (via the included microphone) the audio
characteristics of your speaker system and your listening environment at up to 6
measurement points and automatically tailors the sound for top audio fidelity.
You can set the Audyssey MultEQ to one of the following modes.
- 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 Bypass L/R: Optimizes
all speakers except front left and right.
- Audyssey Flat: Optimizes
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.
Note: You can also setup your speaker system
manually using the receiver. You can select speaker configuration and size
(large/small/none), as well as subwoofer (yes/no). Set subwoofer and LFE
signal range playback (LFE/LFE+Main), as well as low-pass crossover
frequency (80/90/100/110/120/150/200/250Hz). Set distance (0-60') from listening
position to speakers. Set the volume (+/-12dB) of the test tone to be the
same when it is output from each speaker. And set the high-pass crossover
frequency (40/60/80/90/100/110/120/150/200/250Hz) for each speaker.
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. You can set the Dynamic EQ to 0, 5, 10, or 15 dB.
Audyssey Dynamic Volume: Audyssey Dynamic Volume solves the
problem of large variations in volume level between television programs,
commercials, and between the soft and loud passages of movies. 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
heard clearly. When the volume level changes, Dynamic EQ also adjusts the
frequency response to maintain sound quality. You can set the Dynamic Volume to
Day (low), Evening (middle), Midnight (high), or off.
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 Digital, DTS, Dolby Pro Logic (including PL II, PL IIx, PL IIz), and DTS
Restorer: Compressed audio formats such as MP3, WMA (Windows Media Audio), and MPEG-4 AAC
reduce the amount of data by eliminating signal components that are hard for the
human ear to hear. The Restorer function generates the signals eliminated upon
compression, restoring the sound to conditions near those of the original sound
before compression. It also corrects the sense of volume of the bass to obtain
richer sound with compressed audio signals. You can choose from 4 settings:
- Mode 1 (Restorer 64): Optimized mode for compressed sources with
very weak highs.
- Mode 2 (Restorer 96): Apply suitable bass & treble boost for all
- Mode 3 (Restored HQ): Optimized mode for compressed sources with
- Off: Does not use Restored function.
Dynamic Range Compression (DRC): 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, Compressing the dynamic range allows you to hear all of the
sounds in the soundtrack with reduced dynamic range. DRC works when playing
program sources recorded in Dolby Digital or DTS.
Night Mode: The Night Mode optimizes sound for late night listening.
This function can be set to Low, Mid, High, or Off.
Source Level: This function adjusts the playback level of
the currently selected input source's audio input. Use this feature if there are
differences in the input volume levels between different sources. You can correct
the playback level of the audio input from -12 to +12dB.
Tone Settings: You can independently adjust the system's
overall Bass and Treble settings from -6 to +6 dB. You can also fade the sound
from front to rear or vice-versa.
Volume Setting: You can set a
maximum volume level of 0, -10, or -20 dB to limit the receiver's total volume
output. You can also specify a turn-on volume, from
