Description
 
The Integrated Amplifier which carries a LEF circuit original with CEC, and IGM volume control.

The LEF (Load Effect Free) circuit has pure Class-A amplifier structure which adopted the single ended circuit which processes a signal only in one voltage magnification stage and one current amplification stage. Good magnification of the linearity stabilized by this LEF circuit was attained, the NFB loop became unnecessary, and the shortest straight signal course is realized.
Moreover, the automatic bias regulating function is carried and stable signal processing which is not influenced by change of power supply voltage is realized.

In order to make the loss at the time of volume control into the minimum, newly developed IGM (Intelligent Gain Management) is carried.
In IGM, the gain itself is controlled with a central volume element, volume is adjusted, and since the inputted music signal does not go via a volume resistance machine, an Attenuator, and CMOS type volume, it is reducing a noise and distortion sharply.

The full balance circuit is adopted as circuitry.
Moreover, the mutual intervention is suppressed by processing a music signal on either side in the circuit divided into two layers.

The input terminal carries one balanced type XLR terminal in everything but four usual imbalanced type RCA terminals.

The banana plug and Y lug could also be connected to the speaker output terminal, and the terminal with a tunic in which consideration was carried out also to the safe side is adopted as it.

Power-source Kabul has adopted the attachment-and-detachment type.

Two kinds of variations, black and silver, occur.

Wireless remote control is attached.
