7The 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 meating 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.

7Fully balanced control amp with

an linear volume control

The SC-7S2 is a full balanced, two-channel control amp providing the channel separation you need for Super Audio. Based on our own high quality four-gang active volume control we have developed an even better linear control volume that reduces gang errors from 0 to 100dB, ±0.5dB. By adding an additional HDAM SA (Hyper Dynamic Amplifier Module), we improved the Common Mode Reject Ratio (CMRR) dramatically, attaining an incredible ultra-wide frequency band of 150kHz and succeeded in producing the perfect control amplifier for Super Audio CD.

7HDAM SA

The feedback impedance of the Current Feedback circuit was reduced to its minimum to make it faster. We developed a new Hyper Dynamic Amplifier Modules (HDAM), a separeted module operating as a buffer for the amplifier. The SC-7S2 has four HDAM SA on each input-output buffer and another four units on the V/I converter.

7Choke input system

In the power supply section, the choke input topology was adopted to drastically reduce rectifier harmonic noise. This system is especially suitable for a control amplifier in which very small signal amplification occurs.

7Floating control bus system

We make it possible to synchronously drive two or more control amps by using a floating control bus system connected to as many as 6 sets of control amplifiers. We also enable you to trim levels using the remote control, making it easy to set up the optimal sound field on a multi-channel configuration. The highest achievable stereo performance can be accomplished when a system configured with two sets of SC-7S2 and four sets of MA-9S2 are connected in a bi-amped mode.

You will experience superb sound with unbelievable channel separation.
