    Overview

    Designed to elevate your music to new heights, this Onkyo 5.1 Channel AV Receiver is a wonderful addition to your home theatre setup. Experience audio the way the director, producer, or composer intended, with this receiver ready and able to decode Dolby TrueHD and DTS-HD Master Audio, for amazing sound quality. Delivering 135 watts per channel, you can enjoy impactful and full audio across your speakers.

    This pairs quite well with the AccuEQ technology in this unit, minimising distortion caused by the unique layout of your listening space. AccuEQ analyses your speaker positions and creates melodic sound, even if your speaker placement isn’t symmetrical. And with four HDMI inputs, you can easily connect all of your favourite devices including games consoles and Blu-ray players. This couples with HDMI ARC, reducing the number of cables needed to connect your receiver.
    Hi-Res Audio

    This unit is a Hi-Res Audio device, which allows it to play a variety of 24-bit digital audio formats. This simply means you can take full advantage of high-quality audio sources like FLAC audio files.

    Digital Audio Conversion

    Digital audio conversion technology takes high-quality audio signals—e.g. Spotify premium—and creates a clear, virtually noiseless analogue signal. This is especially useful if your speaker setup is wired and your speakers are older. (384 kHz/32-bit conversion to be specific)

    Bluetooth Connectivity

    Wires are out, wireless is in. The simple Bluetooth connectivity in this unit makes it easy to enjoy your favourite music wirelessly.

    High Current Amplification

    The higher the current from amplifier to the speaker, the greater the accuracy of sound that comes out of the speakers. This is needed to prevent phase-shifting—which is when electrical signals interferes with sound—so that you have well-focused, realistic audio.
