The Pioneer Exclusive M7 is a high-performance monaural power amplifier designed to deliver exceptional sound quality. It is engineered with the latest technology to ensure Class A operation, eliminating crossover and switching distortion. The amplifier features a distinct separation of voltage and current amplification circuits, enhancing drive capabilities at low loads while minimizing distortion. Its voltage amplification stage utilizes a hybrid IC with an aluminum substrate for high-precision amplification through negative feedback (NFB). The power amplification stage employs a 5-stage Darlington configuration with parallel arrangements to achieve excellent power linearity. The layout design also prioritizes the separation of voltage and power stages, reducing interference and preserving sound integrity. The amplifier is equipped with both RCA and balanced input terminals, a large-capacity toroidal transformer for stable power delivery, and a protective circuit that bypasses the relay to maintain sound quality. The chassis is robustly constructed to resist deformation and vibration, featuring thick aluminum material and a floating mount for the transformer. Each unit is meticulously hand-crafted and tested for sound quality, with rigorous selection of components. Specifications include a rated output of 480W (2Ω), 240W (4Ω), and 120W (8Ω), frequency response from 5Hz to 100kHz (+0 -1dB), a damping factor of 100 (8Ω), and an SN ratio of 120dB. The amplifier requires a power supply voltage of AC100V, 50Hz/60Hz, with a power consumption of 440W. The overall dimensions are 460mm in width, 220mm in height, and 441mm in depth, weighing 47.0kg.
