marantz SC-6/SM-6 (1979) | ESOTEC Series

 

The Esotec SC-6 inherits all the qualities that established the reputation of the famous Marantz "Model 7" as well as the philosophy that traditionally inspired the design of monitor amplifiers: to offer full listening control possibilities for any musical source. The SC-6 has been equipped with a high-quality preamplifier for moving coil cartridges, a cartridge load selector, independent right and left tone controls, etc. Developed according to the most sophisticated Marantz Hi-Fi criteria, it offers only the best: very low transient intermodulation (TIM) construction, direct-coupled design, all push-pull circuits, and above all, the pursuit of the lowest distortion rate and the highest signal-to-noise ratio. The results of laboratory and listening tests were conclusive: THD less than 0.005%, TIM less than 0.003%, and signal-to-noise ratio greater than 86 dB. The SM-6 can be switch to work in Class A or Class AB operation. The action of a class A amplifier generates a significant amount of heat. The transistors must be kept at normal temperature. Consequently, the heat dissipation required to protect the power amplifier must be very efficient. For the SM-6, a new thermodynamic process developed for NASA, the "heat pipe," was used (a system one hundred times more efficient than the traditional process). Power output: 2x30W in Class A and 2x120W in Class AB. Designed in U.S.A. - Produced in Japan. Original sale price in Germany: SC-6 2000 DM, SM-6 3000 DM.
