The B.M.C. Audio AMP M2 Mono Power Amplifier delivers 200 watts into 8 Ohms and 380 watts into 4 Ohms with a frequency response of 1Hz to 200kHz at 1 watt. It features a fully regulated power supply with a massive 2-kW toroidal transformer and balanced current capacitors for background silence and rock-solid stability. The amplifier incorporates B.M.C.'s exclusive Load Effect Free (LEF) technology, which separates speaker current demand from voltage demand to relieve the Class-A transistor, enhancing signal purity and efficiency. Digital Intelligent Gain Management (DIGM) allows precise volume and balance control in 1-decibel increments via B.M.C.'s DAC 1, eliminating the need for a preamp and reducing noise. Current Injection (CI) technology further improves signal purity by processing the input current up to the loudspeaker output voltage, replacing gain stages with the original signal. The AMP M2 has a modular, robust aluminum chassis with high-quality components, large front panel controls, and a power meter. Connectivity includes balanced XLR and XLR-CI inputs, unbalanced RCA inputs, gold-plated binding posts for speaker outputs, and an AC power connection. It weighs approximately 40 kg (88 pounds) and is designed for distortion-free, dynamic, and transparent musical reproduction with excellent channel separation when used in pairs. The AMP M2 runs cooler and quieter than traditional Class A designs and maintains consistent dynamics without compression or feedback distortion.
