The McIntosh MC2125 is a 2-channel solid-state amplifier that was manufactured between 1976 and 1981. Rated at 120 Watts per channel (125W x 2), it can also operate as a single-channel unit with a maximum output of 240 Watts. This amplifier features unique autoformers that enable optimized speaker connections with 2, 4, 8, and 16 Ohm taps, enhancing its compatibility with various speaker impedances. One of its notable attributes includes a glass faceplate, which helps in maintaining aesthetic integrity over time, preventing the common degradation associated with metal faceplates. The amplifier is equipped with blue glowing meters, an array of controls for channel gain adjustments, meter range selections, and a POWER GUARD system that provides visual feedback on power output status. It also has stereo and mono mode switching allowing peak performance of around 250-300W in mono. The design allows for integration with newer McIntosh components due to consistent design language. The MC2125 is appreciated for its straightforward operation, allowing fine-tuning through multiple controls, yet it maintains a classic vintage look that appeals to enthusiasts. Examples in good condition exhibit minimal wear, especially in chrome areas, which are susceptible to rust if improperly stored.
