Description

The integrated amplifier that has been further refined on the basis of the E-210 and developed as an amplifier with a higher degree of perfection.

The power amplifier uses a high-performance audio power transistor with excellent characteristics such as linearity and switching current amplification factor. This element is configured with a parallel push-pull design and mounted on a large heat sink for efficient heat dissipation.
In addition, the operation | movement versus heat utilization | adopts the power MOS FET with negative characteristic since the driver stage, the power transistor with positive characteristic and a thermal inclination are canceled, and stable operation is guaranteed.

The E-211 adopts the current feedback type amplifier circuit which returns an output signal in the form of current.
The principle of this circuit is to lower the impedance of the input terminal, which is the feedback side, detect the current, and convert the current to IV (current-voltage) with a transformer impedance amplifier to create an output signal. Therefore, since the impedance of the feedback input side is low, it is difficult for rotation to occur. fase and it is almost not necessary to ensure the fase.
As a result, various characteristics can be significantly improved with a small amount of NFB, so dynamic characteristics such as rising are excellent and a natural energy response is achieved.

The relay logic control system that electronically controls a relay is adopted because a straight signal path is formed in the shortest way.
The sealed relay for the communications industry is adopted as the relay used for this purpose, and the contact utilizes the low contact resistance and high durability through the gold bonding and double crossover method.

Tone control of the additional type active filter system used for a graphic equalizer is carried out in the tone control.
In this system, the original flat signal passes straight through and, if necessary, another characteristic is created and, by adding or subtracting from the flat signal, a more advantageous structure in terms of sound quality is obtained than conventional pitch control.

A power transformer with a large power capacity of about 400 VA is used in the power section.
Additionally, two 22.000 microF things are carried in the aluminum electrolytic capacitor that converts the pulsating current passing through the rectifier into direct current.

Direct reading peak power meter with logarithmic compression output is carried.

The balance input is carried over.

Equipped with speaker terminals that can support thick speaker cables.
You can switch and use two systems or bi-wiring is possible.

A remote control is included that can change volume and input.

Equipped with an optional card slot, it can be expanded with a card that supports the AAB (Accuphase Analog Bus) standard.
