7-Channel Amplifier: The Denon AVR-1611 features a 7-channel,
equal power, discrete amplifier. Each channel is rated at 75 watts RMS. The seven
amplifier channels built into the receiver are typically used for 7.1 channel
surround in the main room, but there are various amplifier configurations to
accommodate your home theater setup:
- Normal: The AVR-1611 is designed to be used as a 7.1ch
surround sound receiver with front left/right, center-channel, surround
left/right, and surround back left/right channels along with a preamp
- Zone2: The surround back channel
amplifier can also be assigned to power stereo speakers in Zone2.
- Bi-Amp: You can configure the amplifier for front
bi-amp operation to achieve a higher-quality 2-channel sound by connecting
the receiver's front and surround back channels to your main front speakers
- Front B: A second set of front speakers can be powered
by the surround back amplifier.
- Front Height: To enjoy Dolby Pro Logic IIz you can reassign the
power amp from the two surround back channels to the two front height
channels for better front effects.
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.
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-1611's Audyssey MultEQ 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 (up to six positions
including the main position). This measured data is then analyzed using a program
to improve acoustic characteristics in the listening area; the main position is
given more weight in the calculations. Audyssey EQ offers the following options:
The MultEQ function has the following
- 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
- 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. You can set the Dynamic EQ to 0, 5,
10, or 15 dB.
- 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 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.
Note: You can also setup your speaker system manually
using the receiver. You can adjust speaker configuration (large/small/none),
bass setting (LFE/LFE+Main), low-pass crossover
(80/90/100/110/120/150/200/250Hz), speaker distance (0-60'), channel level
(-12 to +12dB), and high-pass crossover frequency

function only works in the Dolby Digital, DTS, Dolby Pro Logic (including PL II, PL IIx,
PL IIz), and DTS Neo:6 modes.
- 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 TrueHD.

pre-compression form, correcting the sense of bass and treble volume to obtain a
richer sounding playback; select 64, 96, or HQ based on the compression setting
of the source material.
Auto Lip Sync (Audio Delay):
This feature automatically compensates for the timing shift between the audio
and video of the receiver. If needed, the audio signal can be manually delayed
to match the video signal; adjust from 0-200ms.
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 -80 to +18dB or Last
(whatever the volume setting when the receiver was turned off).
Adjustment: You can set the amount of attenuation for the audio muting circuit; -40dB
or -20dB below current volume, or full mute (sound turned off entirely).
