More details on the Onkyo TX-NR525
Features & specs
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 affect performance.
- 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 your music.
- 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 reproduction.
Multi-Channel Decoding Formats: The Onkyo TX-NR525 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.
- Dolby Digital: Dolby Digital, Dolby Digital Plus, Dolby TrueHD
- DTS: DTS, DTS-HD Master Audio, DTS-HD High Resolution, DTS Express, DTS 96/24, DTS Neo: 6,
- Dolby Pro Logic: Dolby Pro Logic II
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, and jazz.
- 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 in mono.
- 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 preference.
- 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 channel).
- 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 height.
- 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 overpower them.
- 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 (single/dual).
- 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.
- Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted. When you connect an iPod or iPhone to the USB port on this receiver, no sound will be output from the headphone jack.

- 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.
- Auto: Detects the signal and automatically selects the input sources.
- Source: Selects the input source (BD/DVD, 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 on-screen.
Note: If no video signal are present, the thumbnails will be filled in black. With 3D video signals, the image may not be properly rendered on the preview thumbnails of InstaPrevue.
