Onkyo M-80 Power Amplifier

Onkyo M-80 Power Amplifier The Onkyo M-80 is a reference-grade stereo power amplifier engineered for audiophiles who demand the ultimate in power, control, and sonic purity. Delivering 200 watts per channel into 8 ohms, it is built around Onkyo's WRAT (Wide Range Amplifier Technology) with a massive high-current toroidal transformer, fully balanced circuitry, and a dual-mono construction that ensures complete channel separation. Whether paired with the Onkyo P-3000R preamplifier or any high-quality preamp, the M-80 delivers an authoritative, effortless sound that brings your music to life. Key Features 200 W x 2 channels (8 ohm, 20 Hz–20 kHz, 0.05% THD) — reference-grade stereo power Dual-mono construction with independent power supplies per channel for complete channel separation Balanced XLR and unbalanced RCA inputs for maximum flexibility and noise rejection WRAT (Wide Range Amplifier Technology) with high-current toroidal transformer for low-distortion, wide-bandwidth amplification Three-stage Darlington circuit with 10 output transistors per channel for high-current drive capability Instrumentation amplifier for superior common-mode noise rejection on balanced inputs Speaker A/B switching for two pairs of loudspeakers Trigger input for system integration and auto power-on Heavy-duty binding post speaker terminals for secure, low-resistance connections Soft-clipping circuit to protect speakers during high-level transients Reference-Grade Engineering The M-80's dual-mono architecture places a dedicated toroidal transformer, rectifier, and filter capacitor bank for each channel, eliminating crosstalk at the power supply level. The three-stage Darlington output stage with 10 transistors per channel delivers enormous current reserves, allowing the M-80 to drive even the most demanding loudspeakers with ease and composure. Fully balanced signal paths from XLR input to output stage ensure the lowest possible noise floor. System Integration The M-80 is designed to work seamlessly within a high-end separates system. A 12 V trigger input allows automatic power-on when paired with a compatible preamplifier or AV processor. Balanced XLR and unbalanced RCA inputs accommodate any source, and heavy-duty speaker binding posts accept bare wire, spades, or banana plugs.
