Description

The McIntosh MC901 Dual Mono Amplifier is a revolutionary monoblock designed for ultimate bi-amplification. It uniquely combines a 300-Watt vacuum tube amplifier (for mid/treble) and a 600-Watt solid-state amplifier (for bass) within a single chassis. Each section boasts dedicated power supplies and McIntosh’s signature output technologies: Unity Coupled Circuit for tubes and Autoformerā„¢ for solid-state, ensuring full power delivery into any 2, 4, or 8 Ohm load.

Proprietary features like Power GuardĀ® and the new Power Guard SGSā„¢ protect speakers and tubes. Its DualViewā„¢ Power Output Meter independently displays each section’s output. An internal adjustable crossover allows precise frequency tailoring. With balanced and unbalanced inputs, and iconic McIntosh aesthetics, the MC901 offers unparalleled sonic performance and flexibility.

Features

– The MC901 Dual Mono Amplifier is truly a one-of-a-kind monoblock amplifier designed as the ultimate solution for bi-amping loudspeakers.
– What makes the MC901 so unique is that it’s two amplifiers combined into one. Adding to the uniqueness is that each amplifier is of differing designs: the MC901 consists of a 300 Watt vacuum tube amplifier attached to a 600 Watt solid state amplifier on one unified chassis.
– The 300 Watt vacuum tube portion powers the mid and upper drivers; the 600 Watt solid state section drives the power hungry woofers.
– The full power is available to almost any speaker regardless if it has 2, 4
or 8 Ohm impedance via our Unity Coupled Circuit output transformer in the vacuum tube section or our Autoformerā„¢ in the solid state section.
– Each amplifier section has its own discrete power supply so neither siphons power or performance away from the other.
– Internal, adjustable crossover allows you to optimize the performance of both amplifier sections to your listening preferences.
– Features our new DualViewā„¢ Power Output Meter that independently displays the real time power reading of each amplifier section.
– Power GuardĀ® helps prevent distortion and clipping in the solid state section. New Power Guard Screen Grid Sensorā„¢ (SGS) helps prevent premature vacuum tube failure by monitoring the screen grid current in the KT88 output vacuum tubes. If the current becomes too high, Power Guard SGSā„¢ dynamically attenuates the input signal in real time to keep the vacuum tubes operating at safe levels.
