What Legends are made of..... We’ll never forget the impact the introduction of the Marantz Model 7 and Model 9 had on the industry more than 40 years ago. These models fused original circuit design with rational thinking and aesthetic appeal. Not only did these models help establish the Marantz name and brand in the audio world, but also influenced the direction that audio evolution has taken ever since. Today, the Model 7 and Model 9 remain an industry standard and have secured a place in the analog era.
PAGE 3
Stereo Control Amplifier SC-7S1 The concept: channel separation for super wide range & dynamic audio We think it’s of the utmost importance to extend high frequency response as well as channel separation so you can hear the true meaning of “Super Audio.” This is why we have designed the input and output circuitry, volume control section, and power supply circuits according to this philosophy. The result: an astonishing channel separation of over 100dB at 20kHz.
PAGE 4
SC-7S1 MA-9S1 Multi-channel audio has come of age and Super Audio sets the standard. We have produced the SC-7S1, a new control amplifier inspired by the legendary Model 7, which long reigned supreme as the ultimate performer in its class. The capabilities of the SC-7S1 are inherited from one of the original components of audio perfection. The pure blue indicator is faithful to the tradition of the legendary Marantz brand.
