SATRI CIRCUIT

OVERCOMING THE LIMITS


The SATRI Circuit,

represents a total solution for overcoming limitations of conventional circuits.

Amplifiers that play recorded sound existed since the Edison’s “Phonograph”.

Such amplifying technology is already in our everyday lives, and the so called high-end audio is still produced based on the same technology.

However, those made with the conventional amplifying technology possess several limits in playing back the sound source exactly, which is the fundamental function of the audio.

In order to overcome such limits, the SATRI Circuit was developed by Bakoon Products through several decades of research and development.

The SATRI Circuit initially began with the current input & current output amplifying circuit in late 1980s. Through continuous developments, the development range has been broadened, and the SATRI Circuit now includes the overall circuit design methods to achieve the desired precision of audio circuits.

It is of utmost importance for high-end audio products to reproduce music as precise and as close to the natural, live musical performances. This is Bakoon Products’ one uncompromising goal, for which we have dedicated decades of experience and effort to.

SATRI Circuit Concept

Let us explain the basic concept of the SATRI Circuit using the SATRI-IC. (Figure A)

Conventional amplifiers have high input impedance and low output impedance. This is mainly because it is more convenient to control the voltage signals in the circuit. However, the SATRI Circuit is completely opposite that the input impedance input of the SATRI Circuit is close to 0 Ohms, and the output impedance is above 100 M Ohms. With such behavior, the SATRI Circuit strictly works with the current signals of the circuit.

Conventional Amplifier Circuit

As can be seen above in the formula (Figure B), the input voltage signal (Ein) is converted to the input current signal (Iin) by the input resistor (R). As the input impedance of the SATRI-IC is close to 0 Ohms, the voltage signal is converted preciously into the current signal.

Then the input current signal (Iin) goes into the SATRI-IC, from which the output impedance of the signal is converted to above 100 M Ohms, while the current signal itself remains the same. As the output impedance is very high now, the output current signal goes into the output resistor (RL) without any loss. By this output resistor (RL), the current signal is converted back to the voltage signal.

Summing up this procedure, the SATRI Circuit’s formula of the overall gain level can be just simplified to RL / R, meaning that the amplification involves two resistors only. As a result, the circuit is now perfectly linear without uses of any other complicated unnecessary circuits, which would only distort and introduce more noise source in the circuit.

Because of such simple and smart design, the SATRI Circuit yields superiority over any other available conventional designs, and this also explains why Bakoon Products produces the most precise and natural sounding products.
