This product has been confirmed to be in working order. Everything shown in the images is included. *This item was sold in Japan as the Amcron D-75A, but it is a US specification model and remains at 120V. The D series is a compact power amplifier with high reproducibility. Its natural sound quality without any sense of discomfort makes it ideal for nearfield monitors and headphone systems in recording, broadcasting, and various production studios. Distortion is kept extremely low, and the wide dynamic range supports digital formats. The harmonic distortion and intermodulation distortion are kept extremely low, achieving an excellent dynamic transfer function. The AB+B class circuit is adopted to achieve high output efficiency while suppressing crossover distortion. The excellent damping factor of over 400 accurately controls the movement of the speakers. Protection circuits are installed against output shorts and opens, load mismatches, excessive input, and high-frequency overloads. Protection circuits are installed against output shorts and opens, load mismatches, excessive input, and high-frequency overloads. The compact EIA 1U chassis reduces installation space. A headphone jack is provided on the front panel. A 31-step click-stop level control is mounted on the front panel. It is equipped with an IOC (Input/Output Comparator) indicator that detects distortion of 0.05% or more, and a SIGNAL indicator that detects the presence of an output signal. 6010208 A31
