5 channel Amplifier
Onkyo TX-NR509 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
Onkyo TX-NR509's 5 channel amplifier can be assigned for different speaker configurations.
- Configurations: Available configurations are:
- 5.1 with internal amplifier.
- Audyssey: Onkyo TX-NR509 comes with Audyssey Dynamic EQ and Dynamic Volume.
- Dynamic EQ: selects the best possible frequency response and surround volume levels moment-by-moment. This ensures that the bass response, tonal balance and surround impression remain constant despite changes in volume. This is the first technology that carefully combines information from incoming source levels with actual output sound levels in the room, a pre-requisite for delivering a dynamic volume solution.
- Dynamic Volume: Your Listening experience can be greatly diminished when there are significant shifts in volume between television programs, commercials and within the program material itself. When this happens you must constantly adjust the volume to maintain your desired listening level. Audyssey Dynamic Volume monitors the volume of program material moment-by-moment and automatically adjusts it, maintaining the desired listening level for all content while optimizing the dynamic range to preserve impact.
- Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-NR509 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.
Onkyo TX-NR509 comes with Audyssey 2EQ room correction system and includes the calibration microphone.
- Audyssey Room Calibration: Audyssey is an acoustic measurement technology which automatically restores the acoustic distortion caused by the acoustic behaviour of a room with only a push on a button. Audyssey equalization provides an clear, accurate, natural sound with voices and dialog that become focused and intelligible, restoring the musical balance. Musical instruments and sound effects become precisely localized and the surround soundstage is made seamless and enveloping.
Onkyo TX-NR509 features 4 HDMI inputs. It has 1 output.
- 1080/60p Passthrough: All inputs pass up to 1080p video signal.
- 3D Ready: Onkyo TX-NR509 is able to pass 3D video through HDMI.
Onkyo TX-NR509 offers multi-zone playback which allows you to play different input sources in 2 different rooms.
- Audio Line Output: If you have a dedicated integrated amplifier for Zone 2 you can connect it to the a/v receiver via line outs by sending fixed signal and then control volume on the Zone 2 amplifier.
Inputs and Outputs
- Analog Pre-Outs: Onkyo TX-NR509 has 2.1 preamplifier outputs which allow you to connect the a/v receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the a/v receiver to power the rest.
- Analog Line Inputs and Outputs: There are 6 line inputs and 1 line output for analog audio connection.
- Digital Inputs and Outputs: 0 optical input, 2 optical outputs and 2 coaxial inputs are available for digital audio connection.
- Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.
- Inputs: 4 Outputs: 1
8K Inputs: 0
- Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
- Inputs: 5 Outputs: 2
- Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one.
- Inputs: 2 Outputs: 1
