Brand: Marantz

The Marantz ST400 is a high-end audiophile integrated amplifier that was introduced by the Japanese manufacturer in the late 1970s. It features a unique differential circuit design, which separates the signal path into two identical channels with opposite polarity, improving noise reduction and signal purity. The ST400 also employs Marantz's EMI (Electromagnetic Interference) shielding technology to minimize electromagnetic noise and interference from external sources. It has a power output of 35 watts per channel into 8 ohms or 50 watts per channel into 4 ohms, and supports both moving magnet and moving coil phono cartridges. The ST400's high-quality components and advanced technologies make it a sought-after amplifier among audiophiles and music lovers who value sound quality and performance.Technical Specifications:- Power output: 35 watts per channel into 8 ohms; 50 watts per channel into 4 ohms- Frequency response: 20 Hz to 20 kHz (+0.2 dB), 20 Hz to 100 kHz (-3 dB)- Input sensitivity: Moving magnet phono cartridges: 3.5 mV; Moving coil phono cartridges: 0.4 mV (100 ohms); Linear inputs: 200 mV- Input impedance: Moving magnet phono cartridges: 47 kohms; Moving coil phono cartridges: 100 ohms; Linear inputs: 47 kohms- Signal-to-noise ratio: More than 80 dB (phono) and 65 dB (line inputs)- Total harmonic distortion: Less than 0.2% (35 watts/8 ohms)- Damping factor: More than 150- Channel separation: More than 75 dB (1 kHz)- Inputs: Two phono (MM or MC), four line-level (one direct, one fixed level)- Outputs: Preamp output (fixed-level)- Topology: Differential circuit design- Construction: Point-to-point wiring, shielded chassis, EMI shielding technologyDimensions:- Width: 435 mm (17.1")- Height: 154 mm (6.1")- Depth: 375 mm (14.7")- Weight: 17 kg (37.4 lbs)
