CEC AMP3300

Commentary

This is an integrated amplifier developed using the know-how obtained in the development of the high-end model AMP71.

The amplifier circuit is a pure class A amplifier using a single-ended circuit in which one transistor processes all music signals.
Conventional class-A amplifiers have disadvantages such as low efficiency, extremely low output, and high temperature during operation. However, the AMP3300 incorporates a LEF (Load Effect Free) circuit to achieve both high-efficiency high power and pure class-A amplification.

By installing a LEF circuit unique to CEC, stable amplification with good linearity is realized. This basically eliminates the NFB loop and realizes a straight and shortest signal path with only one voltage amplification stage and one current amplification stage.
It is also equipped with an automatic bias adjustment function to enable stable signal processing.

A fully balanced circuit design is adopted to achieve high speed and low distortion.
Unbalanced inputs are also balanced inside the amplifier.

The separation is improved by processing the left and right music signals on a two divided into two layers.

Newly developed IGM (Inteligent Gain Management) is management).
The center volume controls the volume by controlling the gain itself, thereby eliminating mechanical volume resistors, attenuators, and CMOS-type volume.

Wireless remote control is included.

There are 2 color variations of black and gold.
