Onkyo A50B Icon Integrated Amplifier

Onkyo A50B Icon Integrated Amplifier with Inverted Darlington Amplifier and 32-bit/768kHz Stereo DAC

The Onkyo A50B Icon integrated amplifier powers a hi-fi setup with features that minimize distortion and reduce vibration. It delivers vivid, smooth, and comfortable sound from a wide range of musical sources.

Clear, high-current amplification with low distortion

The three-stage Inverted Darlington Amplifier drives high current signals with minimal distortion, so music stays clear and strong. As a result, the amplifier focuses on preserving signal integrity during playback.

• Three-stage Inverted Darlington Amplifier
• High current signal drive

Noise reduction for cleaner digital-source playback

Patented DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) uses a high slew-rate design to reduce noise generated in very high frequency bands of digital sources. Because DIDRC operates as a discrete signal control circuit in the analog filter of the DAC, it supports cleaner, clearer audio from digital content.

• Dynamic Intermodulation Distortion Reduction Circuitry (DIDRC)
• Discrete signal control circuit in the analog filter of the DAC
• High slew-rate design to reduce very-high-frequency-band noise

Rigidity and vibration control throughout the chassis

Rigid structural elements help suppress vibration and reduce signal degradation. Additionally, the oval chassis structure strengthens the bottom surface and disperses vibration to help keep operation stable.

• 5mm-thick extruded aluminum front panel
• Oval chassis with oval press lines
• Extrusion aluminum heat sink for vibration suppression
• Copper bus bar

Fan-less operation and integrated high-resolution DAC

A fan-less design eliminates noise while the integrated stereo DAC helps reduce distortion. Together, these elements support a refined listening experience without adding mechanical fan sound to the room.

• Fan-less design that eliminates noise
• Stereo DAC (32bit / 768kHz) that reduces distortion

Power supply components selected to reduce vibration and signal degradation

Custom-made capacitors and rigid construction work together to help reduce vibration and signal degradation. Therefore, the amplifier keeps focus on consistent delivery from source to speakers.

• High-quality 10000uF capacitors custom-made exclusively for Onkyo
• Rigid front panels

Frequently Asked Questions

1. How does the A50B reduce distortion during playback? It combines a three-stage Inverted Darlington Amplifier for minimal distortion with DIDRC circuitry and a stereo DAC (32bit / 768kHz) that reduces distortion.
2. What helps control vibration in the chassis? It uses a 5mm-thick extruded aluminum front panel to increase rigidity, an oval chassis with oval press lines to strengthen the bottom surface and disperse vibration, and an extrusion aluminum heat sink for vibration suppression.
3. Does it use a fan, and will that add noise? No. It uses a fan-less design that eliminates noise.
