Product description
MAA 402 amplifier has been successfully implemented with great care. The use of over-sized toroidal transformers with associated bipolar transistors that allow to provide exceptional purity of sounds. This type of infrastructure gives an exceptionally natural softness that faithfully captures the music in the smallest detail. Low noise resistors and capacitors used guarantee the highest sound fidelity.
Functionality
The stereo amplifier is used to amplify the source signal, eg from a CD player, streaming player, radio tuner. We distinguish between integrated and split amplifiers.
The most popular devices are integrated amplifiers, which consist of two main elements: a preamplifier with volume control and power amplifiers. An additional common element in the integrated amplifier is the phono preamplifier, which allows you to connect the turntable directly.
In the last few years, an increasing number of producers have also installed digital-to-analogue converters (DACs) with digital optical and coaxial inputs, and often with USB type B inputs for PC-Audio.
A special variation of integrated amplifiers are integrated stereo systems, in which the producer adds to the amplifier the sound source in the form of a CD player, stream / network player or radio tuner.
Split amplifiers are devices with a physically separated preamplifier and power amplifier. This allows for a much larger selection of configuration options. There is a possibility to choose preamplifiers and power amplifiers from different manufacturers, which is critical for the final sound of a stereo system.
Separate preamplifiers and power amplifiers are usually much more advanced and refined constructions compared to integrated amplifiers - hence more expensive. As it has already been mentioned - the possibility of free combining of various preamplifiers and power amplifiers, which can not be afforded by the owners of classic integrated amplifiers, can not be overestimated.
