Onkyo TX-NR809 (Others version)

Overview

Onkyo TX-NR809 was introduced in 2011. It is equipped with 7 channel amplifier and is capable of 7.1 maximum channel processing.

We evaluated the Receiver and gave 83 overall score out of 100. Our ranking system is based on the amplifier specifications, audio and video features, connectivity, multizone capabilities, radio and many other details.

Amplifier score is based on power ratings, minimum impedance load, power supply, transformer type, total harmonic distortion, damping factor, signal to noise ratio and other small details. Audio score depends on the number of channels, front wide channel support, maximum channel processing, support of audio formats, DAC specifications, room calibration algorithm... Video score is based on HDR, Dolby Vision and video signal passthrough and upscaling, analog to HDMI upconversion. Connectivity score is defined from all wired and wireless inputs and outputs, internet and bluetooth connections, HEOS, SONOS and others. Multizone score depends on the number of zones with their outputs. Radio score is evaluated form digital radio support and analog tuner with its frequency range, signal to noise ratio, harmonic distortion...

Pros and Cons

In this section we present pros and cons of Onkyo TX-NR809.

Amplifier

Onkyo TX-NR809 has 7 channel amplifier and delivers 135 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and also has a stable performance at 4 Ω load. This receiver even supports front wide channels which is found only in a very few high-end receivers these days.

Video Features

The Receiver has 1080p passthrough and 4K upscaling up to 30p.

WRAT

Onkyo TX-NR809 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

3-Stage Inverted Darlington Circuitry

Onkyo TX-NR809 features 3-Stage Inverted Darlington Circuitry. Standard amplifiers employ a negative feedback (NFB) design that counters distortion by feeding back the opposite phase of the output signal into the input stage. Unfortunately, NFB is easily affected by inverse electromotive forces from the speakers, leading to an increase in circuit noise. Three-Stage Inverted Darlington Circuitry is a core Onkyo technology incorporating a low-NFB design that makes the sound more natural. Sensitive to oscillations, this circuitry requires very advanced control technology in order to be incorporated into the amplifier.

THX™ Certification

Onkyo TX-NR809 is THX™ certified which offers optimal performance, superior quality and seamless integration. THX works with partners from the ground up, so that certified products deliver professional quality audio-visual experiences right out of the box. They only certify the very best products with uncompromised quality, performance and consistency. They ensure that THX certified devices play well with lower performing devices and components. THX listening modes make the receiver to have one speaker set up for movies, music and games. They are tested for power output, bass management, signal-to-noise ratio and feature RE-EQ, timbre matching, boundary gain compensation and THX Loudness Plus. The current model has Select™2 Plus class performance. This means that it is ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.

Advanced Music Optimizer

Compressed music enhancement in Onkyo TX-NR809 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.

Audyssey

Onkyo TX-NR809 comes with Audyssey Dynamic EQ, Audyssey Dynamic Volume and Audyssey DSX.

Audyssey 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.

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.

Audyssey DSX allows you to augment a standard five-channel home theater with either two Front Wide or two Front High speakers. The Wide channels create an expansive soundstage and bring out convincing directional effects. Alternatively, Height channels can add a vertical dimension to movie and game soundtracks.

Room Correction

Onkyo TX-NR809 comes with Audyssey MultEQ XT room correction system and includes the calibration microphone.

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.

Connectivity

Onkyo TX-NR809 can be connected to internet using ethernet cable or wirelessly via Front USB (optional UWF-1 sold separately). It has 8 HDMI inputs. There is a phono input with built-in phono stage for connecting the cartridge output of the turntable directly to the Receiver. There are 7.1 multi-channel analog inputs and 7.2 channel analog pre-outs for external amplification.

Front panel has HDMI, USB, Composite Video, RCA Audio and Optical inputs.
