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.

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.
