Onkyo rates it at 130 watts per channel into 8 ohms and 200 watts into 4 ohms.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eIt takes a signal from your preamp over balanced XLR or RCA, and its backlit power meters show the output as you listen. It comes in Black or Silver.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eA Three-Stage Inverted Darlington Output\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe M-80 uses a three-stage Inverted Darlington amplifier with very low output impedance, so it can deliver large current to your speakers. Onkyo keeps negative feedback low so noise from the speaker does not affect the amplifier.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe output transistors are wired in parallel for strong instantaneous current. The driver stage uses Onkyo's DIDRC circuit, a high-slew-rate design that reduces noise in the ultra-high frequency band.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003eBuilt to Control Vibration\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe housing pairs two aluminum side panels with a steel top panel. Onkyo says this three-piece construction increases rigidity and suppresses vibration.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eA custom high-current power supply, 10,000 µF capacitors made for Onkyo and an extruded aluminum heat sink complete the design.\u003c\/p\u003e\n\u003ch3 style=\"font-size:1.05em;margin:0.9em 0 0.25em 0;font-weight:600;\"\u003ePower Meters You Can Read\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eTwo backlit power meters show output in watts. A front button switches the range between x1 and x10 or turns the meters off, and the backlight has its own button.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eHow the M-80 Fits Your System\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe M-80 needs a separate preamplifier or a source with a variable output. Connect it with one pair of balanced XLR cables or one pair of RCA cables, and choose the input with the rear switch.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eTwo sets of speaker terminals, A and B, can run two pairs of speakers. Use 4 to 16 ohm speakers on A or B alone, or 8 to 16 ohm speakers when both play at once.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eA 12V trigger input lets a compatible preamp switch the M-80 on and off, and a cable is included. Auto standby turns it off after 20 minutes with no signal.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eWhat it will not do: it has no volume control, no source inputs and no DAC or streaming. It is a stereo power amplifier, not an integrated amplifier or receiver.\u003c\/p\u003e\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWhat Reviewers Are Saying\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eJeff Wheaton reviewed the M-80 with Onkyo's P-80 preamplifier for Secrets of Home Theater and High Fidelity (October 2026).
