Features & Specs Line Circle

Serious stereo power
A robust Class-AB amplifier delivers 110 W per channel into 8 Ω with vanishingly low 0.08% THD, providing the headroom to control demanding speakers and preserve musical dynamics.
Room-tailored sound
Dirac Live is built in to correct your room’s acoustics; upgrade to full-bandwidth processing for even more precise results as your system grows.
Reference-grade conversion
A 32-bit/768 kHz stereo DAC and DIDRC circuit reduce high-frequency noise for a vivid yet refined presentation from digital sources.
All the connections you need
HDMI ARC for simple TV audio, MM/MC phono for turntables, optical/coaxial digital, USB-A for drive playback, and stereo pre-out to expand with powered subs or external amps.
Stream everything
Play directly via Spotify Connect, TIDAL Connect, Qobuz, Amazon Music, AirPlay 2, Chromecast built-in, and even Roon, all controllable with the Onkyo Controller app.
Built to silence noise
A 5 mm aluminum front panel, oval anti-resonant chassis, copper bus bar, custom 10,000 µF capacitors, and fan-less thermal design keep vibrations and mechanical noise at bay.

Onkyo A-50 Integrated Amplifier Q&A:

Does the A-50 include room correction, and what’s required for full-bandwidth Dirac Live?
Yes—Dirac Live is built in. The included license provides limited-band correction by default; you can purchase an upgrade license from Dirac to enable full-bandwidth correction.
Can I connect my TV directly?
Yes. The rear HDMI (ARC) input lets your TV send audio to the A-50 and supports CEC for volume and power control from the TV remote.
Is the phono input compatible with both MM and MC cartridges?
It is. There’s a dedicated MM/MC phono stage with a rear panel selector and a ground terminal, plus generous overload margins for both cartridge types.
Which Bluetooth codecs are supported?
When receiving, the A-50 supports SBC and AAC. When transmitting (to Bluetooth headphones, for example), it supports SBC, aptX, and aptX HD.
Can I use the USB port as a computer-audio input?
The USB-A port is for storage playback (flash drives, etc.). For computers, use the optical/coaxial digital inputs, HDMI ARC from a TV, or stream over the network.
What streaming and casting options are built in?
Spotify Connect, TIDAL Connect, Qobuz, Amazon Music, Qplay, TuneIn, Apple AirPlay 2, Chromecast built-in, and Roon Ready, controllable with the Onkyo Controller app.
Will it drive 4-ohm speakers?
Yes. The A-50 supports speaker loads from 4 Ω to 16 Ω.
What’s in the box?
The amplifier, power cord, remote controller (RC-991S), speaker setup microphone, and documentation; batteries are included on some models.
