Onkyo TX-SR309 (USA version)

Onkyo TX-SR309 was introduced in 2011. It is equipped with 5 channel amplifier and is capable of 5.1 maximum channel processing.

We evaluated the Receiver and gave 19 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...

In this section we present pros and cons of Onkyo TX-SR309.

Amplifier

Onkyo TX-SR309 has 5 channel amplifier and delivers 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

Video Features

The Receiver has 1080p passthrough.

Advanced Music Optimizer

Compressed music enhancement in Onkyo TX-SR309 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.

Room Correction

Onkyo TX-SR309 does not come with room correction system.

Connectivity

Onkyo TX-SR309 has 3 HDMI inputs.

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