It employs the latest technology in wide band output devices with enhanced low level linearity. This unified current summation drive stage network eliminates the crossover notch problems common in many solid state amplifier designs. The M150 runs cool under most listening conditions and provides a live presentation with none of the hardness normally associated with solid state amplifiers. The output network of this amplifier is resonance free and remains stable even with a 1 micro-Farad capacitor connected across the output terminals. The M150 engenders the fine resolution and liquidity normally associated with tube amplification plus the power and bass control of solid state.
Individual voices remain distinct and clear amidst the crescendo full orchestra and chorus.
The sound of the M150 is pure and true to the source. It has the clarity, focus in time, and natural sound inherent in all Herron Audio products. The M150 incorporates automatic low level d.c. offset cancellation plus high level d.c. shutdown speaker protection circuits. The effects of continuous low level d.c. at the input of the M150 will be nulled out over time and higher levels of d.c. The M150 has an oversized toroidal transformer capable of supplying enough current to power two amplifiers with the ratings of the M150.
