Description
 
The Integrated Amplifier which adopted Acoustone in addition to a LEF circuit original with CEC, or IGM volume control.

AMP5300 has pure Class-A amplifier composition as which one transistor adopted the single ended circuit which processes all the music signals.
Moreover, in order to improve the fault that an output is low, at the low efficiency of Class-A amplifier, the LEF (Load Effect Free) circuit original with CEC is carried. A feebleminded rate and the drive capability over the speaker of low impedance are improved by this LEF circuit.
Furthermore, the automatic bias regulating function is carried and the hardware requirement stabilized more is secured.

It consists of only one voltage magnification stage and one current amplification stage, and since good magnification of the linearity stabilized by the LEF circuit is possible, it has perfect unreturned composition.
The full balance circuit is adopted as circuitry. Furthermore, the channel separation is improved by processing a music signal on either side in the circuit divided into two layers.

In order to reduce the loss at the time of volume control, newly developed IGM (Intelligent Gain Management) is adopted, the gain itself is controlled, and volume is adjusted.
The signal loss generated when an incoming signal goes via a mechanical volume resistance machine or CMOS type volume by this was suppressed, and a noise and distorted play sound which is not are realized.

The newly developed vibration suppression material "Acoustone" is adopted as a sole plate, and unnecessary resonance is suppressed qualitatively [ of a compound ] by several kinds of "ceramics" and "resin."
Moreover, in order to harness the characteristic of this Acoustone, the spike made from a brass is adopted as the leg of AMP5300.

The input terminal also carries two XLR terminals in everything but three usual RCA terminals.

Spring-loaded is adopted as a speaker output terminal.

Wireless remote control is attached.
