Onkyo TX-8220

Onkyo TX-8220: The versatile integrated stereo hi-fi amplifier

The Onkyo TX-8220 is an integrated stereo hi-fi amplifier that delivers an impressive output of 100 W per channel at 6 ohms. This generous power efficiently drives most compact speakers on the market, ensuring dynamic, lively sound reproduction, even during complex musical passages. The amplifier section benefits from Onkyo’s WRAT (Wide Range Amplification Technology), which ensures wide bandwidth and low distortion. The phase-matching amplification circuit, equipped with discrete power transistors, contributes to audio reproduction that’s faithful to the source.

Comprehensive connectivity for all your audio needs

The TX-8220 offers extensive connectivity to meet all your audio needs. On the rear panel, you’ll find 4 RCA line inputs, an MM phono input for vinyl enthusiasts, a coaxial input, and an optical input for digital sources. A pre-amplified subwoofer output is also available to add greater depth to your bass. On the front, a 6.35 mm headphone jack lets you listen to your music in privacy. This variety of connections makes the TX-8220 a versatile amplifier, capable of adapting to different audio setups.

Bluetooth technology for convenient wireless streaming

The integration of Bluetooth 4.1 enables wireless audio streaming from your compatible mobile devices. You can easily stream your music from your smartphone, tablet, or computer. The Auto Connect function simplifies pairing and playback, while improved stability limits audio quality loss. This modern feature fits perfectly into a classically designed amplifier, offering the best of both worlds.

A digital radio tuner for varied listening

The TX-8220 is equipped with a digital radio tuner compatible with DAB+ and FM/RDS. You can store up to 40 preset stations, allowing quick access to your favorites. The RDS (Radio Data System) function displays detailed information about the station and the currently playing track, enhancing your listening experience. Whether you’re into music, news, or radio shows, the TX-8220’s built-in tuner offers a wide variety of content.

Thoughtful design for optimal sound quality

Onkyo paid particular attention to the TX-8220’s design to ensure optimal sound quality. The amplifier uses custom-designed capacitors and an oversized E-I transformer, contributing to precise, detailed audio reproduction. The optimised-gain volume circuit and Direct mode allow for faithful, source-true playback. In addition, the rigid chassis reduces unwanted vibrations, thereby improving overall sonic clarity.

Installation flexibility and sound personalization

The TX-8220 allows you to connect up to two pairs of speakers simultaneously. This feature lets you play music in different rooms or switch between two speaker systems. Bass, treble, and balance controls allow you to adjust the sound to your preferences or your room’s acoustics. These personalization options, combined with the amplifier’s power and sound quality, let you create a tailor-made listening experience.
