Brand: KENWOOD
Model: KA-3300D
Year: 1987
The KA-3300D Digital Integrated Amplifier was introduced by Kenwood in 1987. As response to the growing popularity of CD, the KA-3300D features a built-in D/A converter that will accept Digital signal from a CD player via a optical or coaxial cable. The D/A converter section consists of a 4x oversampling digital filter, left and right independent ladder network type D/A converters, and a 7th-order Butterworth FDNR type discrete low-pass filter. Additionally, in order to support digital sources that use different sampling frequencies, it has a built-in PLL data demodulator that automatically switches the clock (synchronization) frequency between 32kHz, 44.1kHz, and 48kHz. The amplifier section uses a Dynamic Linear Drive (DLD) circuit. This circuit employs two amplifiers, a low-power amplifier and a high-power amplifier. This allows a far better control of loudspeaker load fluctuations. The amplifier also features a New VIG (Voltage Interface Gate) circuit that interfaces the amplifier section and the power supply section. In addition, by keeping the voltage between the base and emitter of the power transistor constant, the VIG circuit suppresses the phenomenon in which fluctuation components generated by the power stage of the amplifier affect the pre-driver stage and driver stage. This allows for smoother signal transfer between the driver stage and the driver stage, enabling purer signal amplification.
