Network & Tuner Functions
Five Channel Amplifier: The Onkyo TX-NR525 AV receiver features a
5-channel amplifier rated
at 80 watts (into 8-ohms, at 20Hz-20kHz, with 0.7%, driving 2 channels).
The AV receiver's amplifier employs WRAT, 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
- 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.
192kHz/24-bit DACs + 32-Bit DSP Processing: This
Onkyo TX-NR525 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 a powerful and highly accurate 32-bit
processing DSP (Digital Signal Processor) for better surround sound
Multi-Channel Decoding Formats: The Onkyo TX-NR525
AV receiver supports the following multi-channel (Dolby Digital, DTS,
Dolby Pro Logic) decoding formats.
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.
Onkyo Original DSP Modes: Onkyo's Original DSP
Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing,
produce more realistic, powerful sound effects for your movie and music
sound tracks based on the type of content and your home theater setup.
You can choose from the following:
- Orchestra: For classical or operatic music.
- Unplugged: For acoustic instruments, vocals,
- Studio-Mix: Suitable for rock or pop.
- TV Logic: Adds realistic acoustics to TV shows.
- Game: The receiver offers four different Gaming
modes - RPG, Action, Rock, and Sports.
- All Ch Stereo: Stereo sound from all speakers.
Ideal for background music.
- Full Mono: All speakers output the same sound
- Theater-Dimensional (T-D): Theater-Dimensional
circuitry takes the complexity out of conventional surround-sound
setups and lets you experience the excitement of surround sound from
as few as two ordinary speakers. Theater-Dimensional's unique
multi-speaker modes let you place up to five speakers conveniently
by the TV, for the most realistic virtual-surround sound possible.
Direct Mode: In Direct mode, audio from the input
source is output without surround-sound processing. This mode delivers
pure sound with minimum sound quality adjustment and filtration.
Audyssey Technology: The TXN-R525 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 speakers' characteristics.
- Audyssey MultEQ Automatic Speaker Setup:
With the supplied speaker setup microphone, Audyssey MultEQ
determines the number of speakers connected, their optimum crossover
frequencies, and their distances from the primary listening
position, then adjusts each automatically. The room's acoustical
properties are then measured and corrected over the listening area
in both the frequency and time domain. There is a threaded insert on
the bottom of the microphone so it can be mounted on a tripod for
accurate listening position placement. Up to 6 listening position
measurements are taken to optimize the surround effect for a broad
area. If you prefer you can also setup your speaker system manually.
- Audyssey Dynamic EQ: Audyssey Dynamic EQ solves
the problem of deteriorating sound quality as volume is decreased by
taking into account human perception and room acoustics. Dynamic EQ
selects the best possible frequency response and surround levels
moment-by-moment as volume is changed. The result is bass response,
tonal balance and surround impression that remain constant despite
changes in volume. Audyssey Dynamic EQ combines information from
incoming source levels with actual output sound levels in the room,
a prerequisite for delivering a loudness correction solution.
Audyssey Dynamic EQ works in tandem with Audyssey 2EQ to provide
well-balanced sound for every listener at any volume level.
- 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 looks at the preferred
volume setting by t he user and then monitors how the volume of
program material is being perceived by listeners in real time to
decide whether an adjustment is needed. Whenever necessary, Dynamic
Volume makes the necessary rapid or gradual adjustments to maintain
the desired playback volume level while optimizing the dynamic
range. Audyssey Dynamic EQ is integrated in Dynamic Volume so that
as the playback volume is adjusted automatically, the perceived bass
response, tonal balance, surround impression, and dialog clarity
remain the same whether watching movies, flipping between television
channels, or changing from stereo to surround sound content.
Surround Parameters: The Onkyo TX-NR525 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).
- Screen Centered Dialogue: By using the front
high speakers, this function moves the center image of the dialogue
upwards, so that the image of dialogue is fixed to the display
- 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-NR525 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 home.
- 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.
- Phase Matching Bass: Onkyo's Phase-Matching Bass
optimizes low frequencies while preserving mid-range clarity. This
means that powerful bass plays back with clear vocals; it doesn't
- Bass & Treble: You can independently adjust the
Bass (50Hz) and Treble (20kHz) of the TX-NR525 from -10 to +10 dB.
Audio Inputs/Outputs: The Onkyo AV receiver offers a
variety of analog and digital audio inputs/outputs.
- Assignable Digital Inputs: The Onkyo receiver
is equipped with one optical digital input and two coaxial digital
inputs. All three digital inputs are assignable. You can choose auto
decoding , PCM, or DTS for the digital audio inputs. Auto will
decode the signal in its original form (Dolby Digital, DTS, PCM,
etc), PCM decodes the signal to 2-channel, while DTS decodes only
DTS formatted sources.
- Binding-Post Speaker Terminals: There are
color-coded binding-post terminals for the following speaker
connections; Front, Center, and Surround. The binding post terminals
will accept bare-wire, pin-connectors, and banana plugs
- Dual Subwoofer Outputs: The receiver is fitted with two
subwoofer outputs to connect dual powered subs for extra bass. Use
6- to 16-ohm speakers.

- Deep/x.v.Color Support: The Onkyo receiver
supports Deep Color and x.v.Color content, which can display a
larger color range than standard-definition schemes. The result is a
more lifelike, vibrant picture.
- ARC (Audio Return Channel): This feature allows
audio to be sent from your compatible HDTV to your receiver through
the same HDMI cable already being used to send audio and video to
your HDTV. This eliminates the need for extra cables connected to
your television. The receiver's main HDMI monitor output supports
the ARC function, while the sub HDMI monitor output does not.
- Auto Lip-Sync: The Lip-Sync function can
automatically synchronize HDMI audio and video that has gotten out
of sync due to the complex digital video processing being performed
by your HDMI-compatible TV. With HDMI Lip-Sync, the audio delay
required to synchronize the audio and video is calculated and
applied automatically by the AV receiver.
HDMI Through: When enabling the HDMI Through
function, regardless of whether the AV receiver is "on" or in "standby"
both audio and video streams from an HDMI input will be output to your
television, via the receiver HDMI monitor output. You can select between
3 HDMI Through functions modes.

VCR/DVR, CBL/SAT, Game, PC, Aux, TV/CD, Port) for which the HDMI
Through function in enabled.
- Last: The HDMI Through function is activated on
the input source selected at the time of setting the AV receiver to
the "standby" mode.
InstaPrevue: InstaPrevue technology provides a live
video thumbnail of the available content on your devices connected to
the receiver via HDMI. As a result, you can preview audio/video streams
coming from up to 5 HDMI inputs previously assigned to input selectors
on your HDMI connected TV. Even with multiple components connected to
receiver through HDMI, you can easily switch between inputs as their
previews are displayed on a single screen on your television. You can
even use the InstaPrevue feature for Picture-in-Picture. You can specify
the number of preview thumbnails, as well as their positioning
Note: If no video signal are present, the
thumbnails will be filled in black. With 3D video signals, the image
