The AMP3800 is a refined model based on the entry-class AMP3300R control power amplifier, widely popular for its cost-effectiveness. The AMP3800 features greatly improved functionality with its large-sized display and simple, user-friendly interface. Though it is still an affordable entry-class model, the AMP3800 has been refined with premium design elements, featuring vastly improved materials for its chassis and parts.
The AMP3800 is a class-A single-ended amplifier featuring LEF (Load Effect Free) circuitry, CEC’s proprietary technology which uses only one voltage amplifier stage and one current amplifier stage, omitting
the negative feedback circuit component which often results in sound signal distortions. LEF circuitry thus allows freedom from transistor characteristics, enabling straight and high quality audio reproduction. Furthermore, the AMP3800 features Intelligent Gain Management (IGM) , a volume control system that adjusts the amplifier gain itself, completely eliminating signal loss by mechanical volume adjustment and achieving low noise and low distortion.
The AMP3800 achieves 64W+64W(8Ω) output power. With a large toroidal transformer placed in the center, its entire circuitry is symmetrical and fully balanced from input to output (power supply excluded). The left and right signals are processed through independent, dedicated circuitries to improve channel separation and to achieve high-quality stereo imaging
The AMP3800 features four normal RCA input connections and one balanced XLR input connection. Combined with a CD player featuring
a balanced output, such as CEC’s CD3800, the AMP3800 enables high quality music reproduction. The REC OUT terminal can be connected to a recording device, as well as active sub-woofers, etc.
Miscellaneous Features
A high-efficiency heatsink placed in the middle of the back panel controls the internal heat and enables stable operation.
The AMP3800 also features a large display whitch indicates the status of the amplifier, such as input selection, and a simple and easy-to-use rotary selector switch.
