The Marantz SC-1000 is a stereo control console designed for high-purity signal transmission. It features a simple and straightforward configuration with a focus on maintaining the integrity of audio signals. The amplifier operates in a fully push-pull pure Class A DC unit, which enhances its performance characteristics. The unit includes a reinforced power supply section, equivalently designed to a power amplifier, and utilizes eight independent power supplies with six shunt regulators to achieve 0 power source impedance. Additionally, the equalizer circuit features an NF-CR type that ensures excellent dynamic range and transient response, contributing to a stable ultra-low output impedance. The SC-1000 is equipped with a balanced output terminal alongside the pin jack, and the volume control utilizes an L/R independent variable high precision conductive system, eliminating the need for balance control. Tone control is handled via a push switch type, minimizing sound quality degradation. The unit provides two independent outputs: Flat Out and Tone Out. High-precision oxygen-free copper wiring is used throughout, implemented with a crimping method that avoids connectors, which are typically a source of sound quality deterioration. The overall design prioritizes carefully selected components to deliver superior sound performance.
