Product information

Description

Onkyo TX-SR3100 is a 5.2-channel surround AV receiver delivering 80 W per channel (20–20 kHz, 8 Ω). Designed for home cinema and multi-channel music playback, it provides HDMI inputs, Bluetooth streaming, advanced audio decoding and room calibration to adapt sound to your listening environment. The receiver supports modern HDR video formats and high-resolution HDMI connections suitable for 4K and 8K sources, while wired speaker connections and a headphone output enable flexible setup options.

Advantages

The TX-SR3100 combines 5.2-channel amplification with Dolby Atmos, DTS:X and Dolby Surround decoding to reproduce immersive three-dimensional sound fields. Four HDMI inputs support high video resolutions and Dynamic HDR formats for clear, color-accurate images, and Bluetooth allows straightforward wireless audio streaming from mobile devices. AccuEQ room calibration and Vocal Enhancer improve clarity by adapting the system to room acoustics and emphasizing dialogue, while Music Optimizer helps restore detail from compressed audio files.

Suitable for

  • Home cinema setups with a 5.2 speaker layout
  • Multi-channel music playback and streaming
  • Gaming systems requiring low-latency, high-resolution HDMI (4K/8K support)
  • Users who want simplified room calibration and clearer dialogue

Key specifications

  • Channels: 5.2 surround amplification, 80 W per channel (20–20 kHz, 8 Ω)
  • HDMI inputs: 4 supporting up to 3840×2160 and 7680×4320 resolutions and Dynamic HDR formats
  • Audio decoding: Dolby Atmos, DTS:X, Dolby Surround
  • Wireless: Bluetooth for audio streaming
  • Wired outputs/inputs: binding posts for speakers, 6.3 mm headphone jack
  • Room calibration: AccuEQ automatic calibration
  • Special modes: Vocal Enhancer, Music Optimizer, Dolby Atmos Height Virtualizer, Klipsch Optimize Mode
  • Color: Black
  • Weight: 8.4 kg

How to use

Connect your front, center, surround and subwoofer speakers to the receiver's binding posts according to the 5.2 layout. Use HDMI inputs to connect video sources such as Blu-ray players, game consoles or streaming devices. After making physical connections, run the AccuEQ room calibration to measure speaker distances and levels; this will optimize output for your room. Pair a phone or tablet via Bluetooth for direct wireless playback, or plug headphones into the 6.3 mm jack for private listening. Select the appropriate decoding or DSP modes (Dolby Atmos, DTS:X, Music Optimizer, Vocal Enhancer) depending on source material and listening preference.

Usage recommendations

For best performance, use high-quality HDMI cables rated for the required resolution and refresh rate, position speakers according to a typical 5.2 layout with attention to the listener’s seating position, and run AccuEQ each time you change speaker placement. Enable Vocal Enhancer for dialogue-heavy content and Music Optimizer when playing compressed audio files. Keep firmware updated to ensure compatibility with the latest HDMI and HDR features.

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
