An integrated amplifier that has been refined to a higher degree of perfection while maintaining the technology and quality of the E-200 series.
The output element employs a multi-emitter type high-power audio power transistor with excellent characteristics such as high-frequency characteristics, current amplification factor linearity, and switching characteristics.
This element is configured with parallel push-pull to achieve low impedance, and is fixed on a heat sink to perform effective heat dissipation processing.
The current feedback type amplification circuit which returns an output signal in the form of current is adopted as a power amplifier part.
This circuit lowers the impedance of the input terminal which is a feedback side, detects current, and carries out I-V conversion of the current with a transformer impedance amplifier, and is making the output signal. Since the impedance of the feedback input part is extremely low, phase rotation hardly occurs and there is almost no need for phase compensation.
As a result, various characteristics can be greatly improved with a small amount of NFB, and a natural energy response with excellent dynamic characteristics such as rising is realized.
The logic relay control system is adopted in order to constitute the shortest straight signal course.
The sealed type relay for communication industry is adopted as the relay used by this system, and low contact resistance and high durability are realized by making a contact a gold-plating and a crossbar twin system.
The addition type active filter system is adopted as a tone control.
In this method, the original flat signal passes straight, another characteristic is made if necessary, and the sound quality is adjusted by adjusting the flat signal.
The speaker terminal of two lines is carried and a speaker change and a bi-wiring connection are possible.
In order to monitor output electric power, the logarithmic compression type analog type peak power meter is carried.
The power supply section is equipped with a large power transformer of about 400VA. In addition, two large capacitors of 22,000μF are mounted on the aluminum electrolytic capacitor for filters.
The insulator made from high carbon cast iron is adopted.
A remote commander that allows volume adjustment and input switching is included.
Equipped with an option board input slot, it is possible to add digital input or analog disk input.
