Audio Features

H.C.P.S. (High Current Power Supply): The Onkyo TX-NR509 is equipped with a H.C.P.S. massive high power transformer to keep your music sounding great at low and high volume levels.

Burr-Brown DACs (Digital-to-Analog Converters): This receiver is equipped with 192kHz/24-bit Burr-Brown DACs to decode and playback high-resolution recordings with less jitter and  clearer sound.

Optimum Gain Volume Circuitry: Optimum Gain Volume Control 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

32-Bit Processing DSP: The Onkyo TX-NR509 is equipped with a powerful and highly accurate 32-bit processing DSP (Digital Signal Processor) for better surround sound reproduction.

Listening Modes: This receiver incorporates a wide variety of listening modes to bring you maximum enjoyment from your audio and video software. You can assign a default listening mode to each input source so that listening mode will be selected automatically when you select the corresponding input source. The following audio formats are supported by the receiver's Listening Mode - Mono, Stereo, 5.1-channel, and 7.1-channel.

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 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).

Listening Angle: While listening in the Theater Dimensional mode you can adjust the listening angle to either Wide (if listening angle is 40-degrees) or Narrow (if listening angle is 20-degrees).

Audyssey 2EQ Automatic Speaker Setup: With the supplied speaker setup microphone, Audyssey 2EQ can measure the number of speakers connected, their sizes, crossover frequencies and distances front he listening position and calculate the optimal speaker setting for you automatically. The supplied microphone includes an attached 19.5' cable that plugs into the Setup Mic input on front of the receiver. There is a threaded insert on the bottom of the microphone so it can be mounted on a tripod for accurate listening position placement. Three listening position measurements are taken, one primary and two secondary, to optimize the surround effect for a broad area. You can also setup your speaker system manually using the receiver.

• Speaker Size: You can set Large or Small for your front speakers; Large, Small or None for your surround, surround-back/front-height, and center speakers; and Yes or No for subwoofer.
• Speaker Distance: The front speaker distance can be set from 1 to 30 feet in 1-foot increments. The center and subwoofer settings can be up to 5 feet more or 5 feet less than the distance you set for the front speakers (30 feet max). The settings for the surround and surround-back speakers are each individually adjustable, and they may be adjusted up to 5 feet more or 15 feet less than the distance you set for the front speakers (30 feet max).
• Adjustable Crossover: This receiver has a built-in high-pass crossover for any of the speakers set to Small. This setting is available when the subwoofer is set to Yes. The frequencies that you can choose from are 40, 50, 60, 80, 100, 120, 150, and 200 Hz. Frequencies lower than the set crossover point are output by the subwoofer.
• Speaker Levels: You can manually adjust the level of individual speakers between -12dB and +12dB; -15dB to +12dB for the subwoofer.

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.

Bass And Treble: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-NR509 from -10 to +10 dB.

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.

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.

Assignable Digital Inputs: The Onkyo receiver is equipped with two optical digital inputs and two coaxial digital inputs. All four 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 all speaker connections - Front, Center, and Surround. The binding post terminals will accept bare-wire, pin-connectors, and banana plugs (single/dual).

Surround Back Pre-Out: The Onkyo TX-NR509 is equipped with a pair of Surround Back Pre-Outs, so you can connect a secondary amplifier to power a pair Surround Back speakers for 7.1ch surround.

Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.

Video Features

HDMI (v1.4): The TX-NR509 has four assignable HDMI v1.4 inputs and one HDMI v1.4 output for connecting DVD players, HDTV set-top boxes, and other video components to your TV or projector. The receiver's HDMI circuitry allows the receiver to output an HDMI audio signal from its speaker outputs, headphone out, and HDMI out so you don't have to run and additional analog or digital cable. The HDMI inputs can accept and switch 480i, 480p, 720p, 1080i, and 1080p video signals to a HDTV. The HDMI inputs will support uncompressed standard or high definition digital video along with the following audio signals: 2-channel linear PCM, Multichannel linear PCM, and Bitstream. Each HDMI input is assignable.

3D-Compatible: The TX-NR509's HDMI v.1.4 connections will accept 3D video from your 3D-ready Blu-ray player and output the video signal in 3D to your 3D-ready HDTV.

x.v.Color: The AV receiver supports x.v.Color, offering a wider color range than the current broadcast standard. For the x.v.Color feature to be useful, the entire video production chain must be compatible (camera-editing-format-player-display).

Deep Color: The Onkyo receiver also supports Deep Color which allows the color depth of video signals passing through HDMI to be raised. The number of colors that could be expressed by 1 pixel was 24 bits (16,777,216 colors) with a standard HDMI jack. However, the number of colors which can be expressed by 1 pixel is 36 bits with a Deep Color enabled HDMI jack. Since the gradation of the depth of a color can be expressed more finely with more bits, continuous color changes can be more smoothly expressed.  For the Deep Color feature to be useful, the entire video production chain must be compatible (camera-editing-format-player-display).

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.

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.

A/V Sync Control: Occasionally, you may need to manually adjust the audio/video signals that are not properly synchronized manually. Typically when using a progressive scanning DVD player. You can correct this by delaying the audio; options are 0 (no delay) to 400 milliseconds, in 20 millisecond steps.

Component Video: There are 2 component video inputs and 1 component video output. The component video inputs and outputs have a bandwidth of 5Hz to 100MHz.
