The Toshiba SC-410 is a quadrophonic auxiliary amplifier that was manufactured between 1972 and 1976 in Japan. Designed to enhance existing stereo systems by providing amplification for rear speakers, it features a wooden and metallic silver finish. The device has a power consumption of 40 W (maximum) and comes with dimensions of 314 x 307 x 119 mm, weighing 2 kg. The original price was approximately 648 DM. The SC-410 includes multiple inputs: its 2-channel inputs handle signals of 300 mV with a resistance of 60 kOhm, while the 4-channel aux inputs accept 300 mV with a resistance of 120 kOhm, and various tape monitor configurations. Outputs include 2-/4-channel tape recording options and pre-out capabilities. In terms of performance, it delivers continuous power of 2x 15 W for 8 Ohm rear speakers, with dynamic power reaching up to 40 W for 4 Ohm speakers. Total harmonic distortion is maintained at 0.8%, and it boasts a frequency response from 20 Hz to 30 kHz. The device features two separate decoder circuits, allowing for the reproduction of both regular matrix and SQ quadrophonic sound sources. Additionally, input voltages are switchable between low, mid, and high settings.
