AMP5300
Commentary

In addition to CEC's unique LEF circuit and IGM volume control, this pre-main amplifier uses Acoustone.

The AMP5300 is a pure A-class amplifier with a single-ended circuit in which one transistor processes all music signals.
In order to improve the low efficiency and low output of class A amplifiers, CEC-specific LEF (Load Effect Free) circuit is incorporated to improve the driving capability for low efficiency and low impedance speakers.
In addition, it has an automatic bias adjustment function to ensure a more stable operating environment.

It is composed of only one voltage amplification stage and one current amplification stage, and the LEF circuit enables stable amplification with good linearity, so it is a complete non-feedback configuration.
The full-balanced circuit design realizes high-speed, low-distortion transmission, and channel separation is improved by processing the left and right music signals in a two layer circuit.

The newly developed Intelligent Gain Management (IGM) gain management (IGM) is used to control the gain itself to adjust the volume.
This reduces the signal loss that occurs when the input signal passes through a mechanical volume resistor or CMOS-type volume, and realizes playback sound without noise or distortion.

A newly developed damping material Acoustone is used for the bottom plate, and unwanted resonance is suppressed by a synthetic material composed of several kinds of ceramics and resins.
Also, in order to take advantage of the characteristics of this Acoustone, the AMP5300 uses brass spikes on the legs.

In addition to the usual RCA Route 3, two XLR terminals are installed as input terminals.

A spring type is used for the speaker output terminal.

Wireless remote control is included.
