Audyssey Technology: The NR1604 features a full package of
Audyssey audio technologies for optimal sound quality. Audyssey Dynamic Volume
offers real-time volume adjustment, while Audyssey DynamicEQ improves your
system's surround effects during low volume levels. Audyssey MultEQ
automatically sets speakers to suit your room's listening environment and the
- 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.
- 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.
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 adjust:
- Panorama: Broadens the front stereo image to the
surround speakers to provide a wraparound effect, especially effective
when 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 or backward.
- 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 7
(nothing subtracted from the L/R channels) to 0 (L/R channel output is cut
- Height Gain: Adjust the volume (Low/Mid/High) of the
Front Height channels in Dolby Pro Logic IIz.
The Marantz NR1604 surround receiver also provides
two-channel stereo and multi-channel stereo playback, as well a virtual surround
from two stereo speakers.
- 2CH Stereo: This is the mode for playing in 2-channel
stereo; bass and treble can be adjusted and sound is output from the front
left and right speakers, along with a connected subwoofer.
- Multi-Channel Stereo: This mode lets you enjoy stereo
sound from all speakers.
- Virtual Speaker: Enjoy surround effects using only the
front speakers or headphones.
The Marantz NR1604 offers two Direct sound modes which
offer high-quality sound by bypassing the receiver's DSP & video circuitry.
Source Direct Mode provides playback of 2ch or Multichannel audio in its
original form, without any surround or tone processing. Pure Direct Mode goes a
step further by turning off the receiver's display and analog video circuitry to
minimize the possibility of any noised being added to the audio signal.
Audio Enhancements: The Marantz NR1604 receiver provides
various audio enhancements to deliver a high-quality listening experience every
- M-DAX: 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 M-DAX 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
- HT-EQ: The tonal balance of
a film soundtrack will be excessively bright and harsh when played back over
audio equipment in the home. This is because film soundtracks were designed to
be played back in large movie theater environments. Activating the receiver's
HT-EQ feature when watching a film made from movie theaters corrects this and
restores the correct tonal balance.
- 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.
- Tone Control: You can adjust the receiver's Bass and Treble
independently to suit your listening taste or room acoustics.
Level Adjustments: The NR1604 provides the following level
- Source Level: This function adjusts the playback level
of the currently selected input source's audio input. Use this feature if

(-79.5 to 18dB).
- Volume Limit: You can set a maximum volume level of 0dB
(80), -10dB (70), or -20dB (60) to limit the receiver's total volume output.
- Turn-On Volume: You can define the volume setting that
is active when the power is turned on (0, 1-98, -79 to +18dB, or Last)
- Mute Level: 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).
Audio Inputs/Outputs: The Marantz AV receiver offers a
variety of analog and digital audio inputs/outputs.
- Assignable Digital Inputs: The NR1604 features an optical
digital (Toslink) input and a coaxial digital input. Each input can be assigned

compatible Apple iOS or Android device. For added convenience, there are eight
customizable home screen short cut buttons that allow you to tailor the look and
function of the Marantz Remote App to suit your needs.
Bluetooth Adapter (optional): Through its proprietary M-Xport, the NR1604
offers Bluetooth capability. Simply add the optional RX101 Bluetooth adaptor (642RX101,
sold separately) to the NR1604 and you can play the music stored on any
Bluetooth-enabled portable device (your iPhone, iPod Touch, or PDA for example)
through your home theater system. The optional RX101 doubles as an IR (infrared)
receiver so you can place all your components out of sight and still maintain
full remote control.
