Onkyo M-80 Class AB Stereo Power Amplifier
Meet the Onkyo M-80 - an Icon Series, Class-AB stereo power amplifier engineered to effortlessly drive demanding loudspeakers while preserving fine musical detail. A three-stage Inverted Darlington output with low negative feedback delivers high current, low output impedance, and lifelike dynamics, while DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) keeps ultra-high-frequency noise in check for a cleaner, more natural presentation. A custom high-current power supply, extruded aluminum heat sink, copper bus bars, and Hi-Fi-grade input/output terminals underscore its no-compromise build. Backlit analog power meters (with x1/x10 range), A/B speaker switching, and a 12V trigger make the M-80 as satisfying to use as it is to hear.

Onkyo M-80 Q&A:
- How much power does the M-80 deliver?
- It outputs 130 W per channel into 8 Ω (20–20 kHz, 0.08% THD, both channels driven) and up to 200 W per channel into 4 Ω at 1 kHz (0.7% THD, 2ch driven). In Europe, the rated figure is 140 W/ch into 4 Ω at 1 kHz (1% THD, IEC).
- Does it support balanced connections?
- Yes—there’s one balanced XLR input and one unbalanced RCA input, with rear-panel input selection.
- What speaker impedances are supported?
- When using Speakers A or B, the amp supports 4–16 Ω loads; when running A + B simultaneously, use 8–16 Ω speakers.
- Is there a 12V trigger for system automation?
- Yes—there’s a 3.5 mm 12V Trigger In jack for synchronized power control with a preamp or controller.
- What’s the frequency response?
- The spec sheet lists 5 Hz–100 kHz (+1/−3 dB); the owner’s manual notes 10 Hz–100 kHz (+1 dB/−3 dB) measured conditions.
- Does the M-80 include a remote control?
- No—operation is via the front panel (On/Standby, meter range, backlight, speakers) or 12V trigger; there is no handheld remote.
- Can I switch between two speaker pairs?
- Yes—Speakers A/B can be toggled from the front panel; follow the impedance guidance if using A + B together.
- What’s included in the box?
- The amplifier, regional power cord(s), a 1.8 m mono mini-plug cable for the 12V trigger, and documentation.
