Onkyo Icon M80B Power Amplifier with 130W Output

Onkyo M-80B Icon Power Amplifier with Three-Stage Inverted Darlington Amplifier and High Current Power Supply

The Onkyo M-80B Icon power amplifier delivers dynamic full-range audio by powerfully driving large speakers with a large current output stage. It maintains a highly resolving and informative presentation because it keeps negative feedback (NFB) low to avoid extra noise from the speaker.

High-current drive for dynamic, full-range playback

The three-stage Inverted Darlington Amplifier provides very low output impedance, which helps the amplifier drive demanding speakers with authority. Additionally, the parallel output-stage transistor configuration improves instantaneous current supply capability, enhancing the rise of sound and the sense of power.

• Three-stage Inverted Darlington Amplifier
• Very low output impedance
• Low NFB (negative feedback)
• Parallel output-stage transistor configuration

Noise reduction for natural-sounding detail

The driver stage uses DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) to reduce noise in the ultra-high frequency band. As a result, the High Slew Rate Design helps produce the natural sound of an analog record.

• High Slew Rate Design

Vibration suppression and rigid construction

Attention to vibration suppression supports clearer playback, and the construction increases rigidity for improved sound quality. The three-piece housing uses two aluminum side panels and a steel top panel, and it also improves seismic resistance.

• Extrusion aluminum heat sink that suppresses vibration
• Two aluminum side panels and a steel top panel
• Three-piece housing construction for increased rigidity

Component choices that support stable power delivery

A custom high current power supply provides dynamic, full-range sound, while key internal parts reinforce the amplifier’s ability to supply current quickly. Copper bus bars and custom-made 10000uF capacitors made exclusively for Onkyo support the power stage, and Hi-Fi grade terminals handle both speaker output and audio input connections.

• 10000uF capacitors custom-made exclusively for Onkyo
• Hi-Fi grade terminals for speaker output and audio input
• Copper bus bars
• Robust vibration-proof front panel

Power output for large-speaker systems

The amplifier outputs 130W into 8Ω from 20Hz to 20kHz with THD 0.07% (2ch driven), and it delivers 200W into 4Ω at 1kHz with THD 0.7% (2ch driven). Therefore, it can powerfully drive large speakers and bring out dynamic acoustic information.

• 130W into 8Ω (20Hz - 20kHz, THD 0.07%, 2ch driven)
• 200W into 4Ω (1kHz, THD 0.7%, 2ch driven)

Frequently Asked Questions

• What amplifier topology does it use to drive speakers with high current?

  It uses a three-stage Inverted Darlington Amplifier with very low output impedance to powerfully drive speakers with a large current.

• How does it address noise for more detailed playback?

  The driver stage uses DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) with a High Slew Rate Design to reduce noise in the ultra-high frequency band.

• What construction features support vibration suppression and rigidity?

  It uses an extrusion aluminum heat sink that suppresses vibration, plus a three-piece housing with two aluminum side panels and a steel top panel to increase rigidity and improve seismic resistance.
