A-50 NETWORK INTEGRATED AMPLIFIER
Exceptional engineering to power your playlist
With several features engineered expressly to minimise distortion and reduce vibration, the Onkyo A-50 Network Integrated Amplifier is the all-in-one solution to power your perfect hi-fi setup.

Three-Stage 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. This advanced amplifier design ensures powerful performance while maintaining exceptional audio fidelity.
DIDRC Technology
Thanks to patented DIDRC circuitry (Dynamic Intermodulation Distortion Reduction Circuitry), the A-50 delivers 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 analogue filter of the DAC. Its high slew-rate design reduces noise generated in very high frequency bands of digital sources.


Superior Construction
A 5mm-thick extruded aluminium front panel increases rigidity and suppresses vibration, while the “oval chassis” with oval press lines strengthens the bottom surface and disperses vibration. Combined with fan-less design that eliminates noise and an extrusion aluminium heat sink, this amplifier provides exquisite and powerful sound.
Premium Components
High-quality 10000uF capacitors custom-made exclusively for Onkyo, a copper bus bar, and rigid front panels further reduce vibration and signal degradation. The premium stereo DAC (32bit / 768kHz) reduces distortion while maintaining exceptional audio clarity throughout the signal path.


Complete Connectivity
Hardwire your turntable, plug in your CD player, and stream your songs with ease thanks to comprehensive connectivity options. With 3 pairs RCA, HDMI ARC, MM/MC phono, coax, USB-A, optical, and headphone output, you have all the flexibility needed for sublime audio experiences.
Modern Streaming Excellence
Seamlessly hardwire or cast your content from built-in platforms: Spotify Connect, TIDAL Connect, Qobuz Connect, Amazon Music, Qplay, TuneIn, AirPlay 2, Chromecast, and Roon Ready. Compatible with Onkyo Controller mobile app for convenient control of various settings and content right from your listening point.


Powerful Performance
With an output power of 180w (4Ω) / 140w (8Ω), the A-50 can powerfully drive a variety of speakers, from large floorstanding speakers to small bookshelf speakers, maximising each system’s potential. Although a single integrated amplifier, it delivers exceptional performance across diverse speaker configurations.
Intelligent Room Correction
Built-in Dirac Live Room Correction Suite Stereo elevates your listening experience by taking your unique system and room setup into account. With frequency response correction, multiple playback modes, and advanced room analysis, this highly sought feature ensures optimal audio performance in any environment.
All-in-One Solution
An integrated amplifier combines the power of a standard amplifier with intelligent signal processing of a preamplifier, providing the best of both worlds in one convenient chassis. Input signals can be controlled and adjusted to your liking, customising the experience according to your speakers, audio type, and musical preferences. Perfect for new audiophiles, experienced users with limited space, or those maximising performance on a budget.
ICON SERIES
The Icon series, developed to be the icon of the Onkyo brand, is not only a renewal of Onkyo’s previous Hi-Fi products but the culmination of Onkyo’s accumulated and continuously evolving sound creation technologies. Built for early adopters and tech enthusiasts, the A-50 represents the perfect balance of power, intelligence, and convenience.
