C.E.C. AMP3300R

Pure Class A Single-Ended Amp
The AMP3300R is a Class A amp that features an extremely pure single-ended circuit with each one single transistor for the non-inverting and inverting lines, that handles all music signal processing. Earlier Class A amps were inefficient, had extremely low output and generate considerable heat when operating, but the AMP3300R uses a load effect free (LEF) circuit to successfully combine high-efficiency power with high-quality pure Class A amplification. The primary technology of the LEF is to avoid various sources of nonlinearities.
CEC's Original LEF Circuit
The AMP3300R features CEC's unique load effect free (LEF) circuit to avoid completely all factors that result in deterioration of sound quality. The LEF circuit makes possible pleasing and detailed playback as well as a high efficiency. The AMP5300R can be used to drive low-efficiency, low-impedance speakers with margin to spare. Every amplifier should be a perfect voltage source in theory, while the current into the speaker is likely out of phase in relation to the voltage. The phase relation varies with the frequency and is even dynamically moving. NFB amplifiers are sensitive to this matter, specifically to the dynamic changes. The LEF's current control stage is not linked to the signal voltage, and just checks the current requirement that depends on the speaker load without "knowing" about the phase relation to the voltage. This "phase independent operation" is an important reason for the obvious drive ability as well as sound quality. The AMP3300R also has an automatic bias adjust function for stable signal processing.
Fully Balanced Signal Processing Circuit
The AMP3300R adopts a full-balanced circuit design to achieve extremely high-speed and low-distortion signal transmission. Unbalanced inputs are converted to balanced in the very first stage of the amplifier with no deterioration of sound quality, resulting in a fully balanced output signal that drives the speakers. In addition, the left and right signals are processed in circuits divided into two layers to ensure channel separation and a high-level stereo image.
IGM Volume Control
The newly developed Intelligent Gain Management (IGM) system is used to minimize signal loss during volume adjustment. Sound volume is adjusted by controlling the gain itself with a knob on the front panel. The input signal is not degraded by any mechanical volume resistor or CMOS device. As a result of this, lowest noise, low distortion and highest dynamic performance has been achieved.
No-Feedback Structure
The AMP3300R has an LEF circuit that makes possible extremely stable and realistic amplification, and since a NFB loop is fundamentally ununnecessary in the signal path, the shortest-possible, truly straight signal route is achieved. The AMP3300R is a completely fedback-free power amp in the signal path that can express all data perfectly with a single voltage amplification and a single current amplification.
Numerous Input and Output terminals
The AMP3300R has four conventional RCA input terminals (unbalanced) and one XLR input terminal (balanced), enabling it to connect to high-quality products with balanced outputs such as CEC's CD3300R. In addition, the AMP3300R can be connected to a recording device, such as tape recorder as well as active sub-woofer. The speaker outputs are spring-loaded terminals that are simple to connect the cables, but not come loose easily.
