About the MA6900

The McIntosh MA6900 is a two-channel solid-state integrated amplifier produced from 2001 to 2012, known for its robust power output of 200 watts per channel into 2, 4, or 8 ohms and its high-fidelity sound quality. It features a 5-band analog equalizer allowing ±12 dB adjustment at 50 Hz, 150 Hz, 500 Hz, 1.5 kHz, and 10 kHz, enhancing tonal control. The amplifier includes multiple inputs: 1 balanced (XLR) input, 5 unbalanced inputs, MM and MC phono inputs, and variable inputs and outputs. It incorporates McIntosh's proprietary Power Guard circuit to prevent clipping and protect speakers, along with thermal sensors, turn-on delay, and direct-current speaker protection for reliability and safety. The frequency response is 20 Hz to 20 kHz with a total harmonic distortion of 0.005%, signal-to-noise ratios up to 110 dB, and a damping factor over 40. The unit weighs approximately 33.8 kg and measures 444.5 mm wide, 181 mm high, and 419 mm deep. It is highly regarded for its powerful, warm sound signature, though it is less detailed compared to newer models. The MA6900 is no longer manufactured but remains a respected classic in McIntosh's lineup.
