7 Channel Amplifier: The Onkyo TX-NR737 AV receiver
features a 7-channel amplifier rated at 110 watts (into 8-ohms, at
20Hz-20kHz, with 0.08%, driving 2 channels). The AV receiver's amplifier
employs WRAT, 3-Stage Inverted Darlington Circuitry, H.C.P.S, and
Optimum Gain Volume Circuitry for dynamic, detailed, clear sound.
- WRAT (Wide Range Amplifier Technology): WRAT is
based around a low negative-feedback circuit topology that works to
reduce signal noise and distortion across the frequency range. A
"closed ground-loop circuit" design is employed, in which each
circuit has a separate link to the power supply. This helps to
cancel individual circuit noise and keep the ground potential free
of distortion. High Instantaneous Current Capability (HICC) enables
WRAT amplifiers to immediately cancel the speakers' reflex energy
and instantaneously send out the next signal. The same high current
better manages speaker impedance fluctuations, which can negatively
- 3-Stage Inverted Darlington Circuitry: The AV
receiver incorporates 3-Stage Inverted Darlington Circuitry into the
front & center channels. This core Onkyo technology employs a low-NFB
(negative feedback) design that makes the sound more natural.
- H.C.P.S. (High Current Power Supply): Under the
anti-resonant cover of any Onkyo receiver, you'll instantly notice
the High Current Power Supply (H.C.P.S.) transformer. With its huge,
isolated power supply design and high-capacity filter capacitors, it
delivers the large amounts of power necessary for reproducing the
wide dynamics of movie soundtracks and the detail and clarity of
- Optimum Gain Volume Circuitry: Optimum Gain
Volume Circuitry adjusts the gain so that less than half the amount
of attenuation is needed, ensuring the signal never comes close to
the noise floor. This protects the signal against noise, resulting
in a dramatically clearer sound.
Amplifier Assignment: The 7-channel amplifier can be
configured in a variety of ways to match your type of speaker setup.
- Normal (7.2ch): The Onkyo TX-NR737 provides 7.2ch
surround in your main listening area. You can choose either Surround Back or
Front Height speakers (but not both).
- Front Bi-Amp (5.2ch): The Surround-Back/Front-High
speaker terminals can be reassigned and used along with the Front terminals
to bi-amp the front speakers, providing improved bass & treble performance.
When bi-amping the front speakers the receiver is limited to a 5.2ch speaker
system in the main room (no Surround Back or Front Height speakers)
- Powered Zone 2 (7.2ch + Zone 2): In this configuration,
you can connect Front, Center, Surround, Surround Back (or Front Height),
and Zone 2 speakers to the AV receiver. When Zone 2 is off, all seven
channels will be used in the Main Zone. However, when Zone 2 is on, power to
the two surround back (or front height) channels will be directed to the two
speakers in Zone 2 and the Main Zone will receive only five channels of
- Dolby Atmos (w/ Firmware Update): The
Surround-Back/Front-High speaker terminals are assigned to power a pair of
overhead ceiling speakers or a pair of Dolby Atmos-enabled speakers to
create 5.2.2ch Dolby Atmos surround sound. Zone 2 speaker can still be
powered by the receiver in the configuration. When Zone 2 is off, all seven
channels will be used in the Main Zone for Dolby Atmos. However, when Zone 2
is on, power to the Dolby Atmos channels will be directed to the two
speakers in Zone 2 and the Main Zone will receive only five channels of
power without Dolby Atmos.
192kHz/24-bit DACs + Dual 32-Bit DSP Processing: This
Onkyo TX-NR737 is equipped with 192kHz/24-bit Burr-Brown DACs to decode
and playback high-resolution recordings with less jitter and clearer
sound. The receiver also employs powerful and highly accurate Dual 32-bit
processing DSP's (Digital Signal Processor) for better surround sound
PLL (Phase Locked Loop): PLL jitter-cleaning circuit
technology reduces jitter by comparing the input and output phases of the
digital signal and creating an accurate clock waveform. This enhances the
precision of digital signal processing and noticeably improves audio quality.
Jitter-cleaning technology works both for digital signals input via HDMI and for
digital signals converted from analog signals inside the receiver itself
AccuEQ Room Calibration: Calibrating the sound to
suit your room's acoustics is simple with Onkyo's AccuEQ auto-room
calibration. Once you've connected your speakers, plug-in the included
mic and wait a few moments as the TX-NR737 measures things such as
speaker distance, type, crossover, and output, taking into account any
reflections from your walls and floor. The system is designed
specifically to by-pass your front left and right speakers. The system
then optimizes the frequency response of the remaining speakers so you
can enjoy balanced surround sound regardless of room shape or furnishing
while retaining the characteristics of your front left and right
speakers for optimum enjoyment
Multi-Channel Decoding Formats: The Onkyo TX-NR737 AV
receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro
Logic) decoding formats.
- Dolby Digital:
Dolby Digital EX,
Dolby Digital Plus,
DTS-HD Master Audio,
DTS-HD High Resolution,
DTS Neo: 6
- Dolby Pro Logic:
Dolby Pro Logic II,
Dolby Pro Logic IIx,

Note: Dolby Digital and DTS listening modes can
only be selected if your audio source is connected to the A/V
receiver via a digital audio connection (HDMI, optical, or coaxial).
To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound,
the receiver must be connected to your Blu-ray player via HDMI.
Dolby Atmos: The TX-NR737 receiver is
(5.2.2ch) compatible through a
firmware update from Onkyo's website.
Dolby Atmos combines
traditional home theater speaker layouts with either ceiling-mounted
speakers or new Dolby Atmos-enabled speakers to create a plane of sound
above the listener. The impact of either in-ceiling or Dolby Atmos-enabled
speakers is breathtaking. Your room fills with realistic,
multidimensional sound that places you directly in the center of the
- Ceiling Mounted Speakers: Ceiling speakers are used for
maximizing effects in Dolby Atmos listening mode. Install these speakers
midway between the position just above the listening position and the
position just above the front speakers, or simply install them just above
the listening position.
- Dolby Enabled Speakers: There are two types of Dolby Enabled
Speakers; one is to be placed on the top board of other
speakers such as front speakers and surround speakers; the other is
integrated within the front or surround speakers. Dolby Enabled Speakers are
designed with their output facing toward the ceiling to create an elevated
audio effect in the Dolby Atmos mode by providing sounds echoing off the
Note: Globally, more than 100 cinema blockbusters have been
released featuring Dolby Atmos soundtracks in the past two years, and many
more are on the way. Major Hollywood studios are partnering with Dolby to
create home video versions of both current box office releases and
previously released favorites for release starting in 2014.
Dolby Surround offers an enhanced cinema experience to your Dolby Digital
(Plus/TrueHD) and DTS (ES/HD) movie soundtracks using your existing 7.1ch or
Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving
the spatial dimension and overall audio definition of movie soundtracks. It does
this by using four distinct surround zones that provide greater control over the
exact placement of each detail in a movie sound track, so audio can be matched
more accurately to the video on screen; this means more depth and greater
realism for your movies. As a result, individual sounds are clearer and more
distinct. It also improves the surround sound experience across the entire
theater by widening the listening "sweet spot".

Surround Parameters: The Onkyo TX-NR737 lets you
tweak and fine tune specific surround sound modes to suit your
- 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), Dimension (allows you to move the sound field forward or
backward), and 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).
- Pro Logic IIz Height Gain: The Height Gain
Control in Dolby Pro Logic IIz enables the listener to select how
much gain is applied to the front high speakers. There are three
settings, "Low", "Mid" and "High", and the front high speakers are

- Listening Angle: While listening in the Theater
Dimensional mode you can adjust the listening angle to either Wide
(if listening angle is 40°) or Narrow (if listening angle is 20°).
Audio Enhancements: The Onkyo TX-NR737 receiver
provides various audio enhancements to deliver a high-quality listening
experience every time.
- CinemaFilter: Using the CinemaFilter you soften overly
bright movie soundtracks. Movie soundtracks are typically mixed for a large
theater (relative to your home theater) with lots of soft seats and thick
curtains on the walls. Home theater settings often lack these high frequency
absorbing wall treatments, making the soundtrack sound too bright.
CinemaFilter accounts for this and for many movies sounds more natural at
- Music Optimizer: The Music Optimizer function enhances
the sound quality of compressed music files. The Music Optimizer function
only works with PCM digital audio input signals with a sampling rate below
48kHz and analog input signals.
- Late Night Feature: The Late Night feature limits the
dynamic range of Dolby Digital recordings. Limiting the dynamic range makes
it easier to find a volume that ensures the quiet sounds are not too quiet
and the loud sounds are not too loud for night time listening. This allows
you to comfortably listen to without the need to constantly adjust the
volume to keep from waking family/neighbors. The choices are: Off, Low, and
High. This feature only works with Dolby Digital Encoded software and the
depth of the feature will vary based on the individual software package.
Bass Management: The Onkyo AV receiver offers Tone Control
and Phase Matching Bass technology to get the most bass impact out of your
