A-50

Network integrated amplifier

With several features engineered expressly to minimize distortion and reduce vibration, the Onkyo A-50 Network Integrated Amplifier is the all-in-one solution to power your perfect hi-fi setup.

Inverted Darlington Amplifier

A three-stage Inverted Darlington Amplifier drives high current signals with minimal distortion, so your content is just as clear and strong as the artists intended.

Dynamic Intermodulation Distortion Reduction Circuitry (DIDRC)

Thanks to patented DIDRC circuitry (Dynamic Intermodulation Distortion Reduction Circuitry), the Onkyo A-50 Integrated Amplifier delivers a vivid yet smooth and comfortable sound from any musical source. DIDRC is a discrete signal control circuit designed to embody Onkyo’s sound philosophy, used in the analog filter of the DAC. DIDRC’s high slew-rate design reduces noise generated in very high frequency bands of digital sources, resulting in cleaner, clearer audio.

Aluminum front panel

A 5mm-thick extruded aluminum front panel is used to increase rigidity and suppress vibration.

An oval chassis

The “oval chassis” with oval press lines strengthens the bottom surface and disperses vibration.

Fan-less design

Combined with a fan-less design that eliminates noise, a premium stereo DAC (32bit / 768kHz) that reduces distortion, and an extrusion aluminum heat sink for vibration suppression, this amplifier provides an exquisite and powerful sound.

High quality capacitors

High-quality 10000uF capacitors custom-made exclusively for Onkyo, a copper bus bar, and rigid front panels further reduce vibration and signal degradation.

Everything you need for sublime audio experiences

Hardwire your turntable, plug in your CD player, and stream your songs with ease thanks to the Onkyo A-50’s many connectivity options. With 3pairs RCA, HDMI ARC, MM/MC phono, coax, USB-A, optical, and headphone output, you have all the flexibility.

The modern audiophile

Hardwire or cast music

Seamlessly hardwire or cast your content from: Spotify connect, TIDAL connect, qobuz connect, Amazon Music, Qplay, TuneIn, AirPlay 2, Chromecast, Roon Ready

Compatible with Onkyo Controller
The A-50 is compatible with Onkyo’s mobile app, the Onkyo Controller which controls various settings and content right from your listening point

Create your perfect system

The A-50 has an output power of 180w(4Ω, 1kHz, THD 0.7%, 2ch driven) / 110w(8Ω, 20-20 kHz, THD 0.07%, 2ch driven). Although a single integrated amplifier, it can powerfully drive a variety of speakers, from large floorstanding speakers to small bookshelf speakers, maximizing each system’s potential.

Dirac Live to correct your room’s acoustic flaws

Onkyo builds world-class products for early adaptors and tech enthusiasts. It’s what sets us apart from the rest, and the A-50 Integrated Amplifier is no exception. That’s why it comes with built-in Dirac Live Room Correction Suite Stereo. With frequency response correction (Limited : 20～500Hz / Licensed, Full version : full bandwidth / Need to purchase a license), multiple playback modes, and more, this highly sought feature will elevate your listening experience by taking your unique system and room setup into account.

From Onkyo academy: Benefits of an integrated amplifier

An integrated amplifier combines the power of a standard amplifier, with the intelligent signal processing of a pre-amplifier, to provide the best of both worlds in one convenient chassis. Input signals from your device (music source) can be controlled and adjusted to your liking – which may vary depending on the speakers you listen through, the type of audio being played, the musical genre, etc. – and customize the experience accordingly. The power amp takes those signals and literally powers them into your speakers.

From Onkyo academy: Why choose an integrated amplifier

Many who choose an integrated amplifier are either new to the hobby, experienced audiophiles with limited space for equipment or choosing to maximize performance on a budget.
