The difficulty is carried out of the sound system design and commissioning 2, there is one and two types of sound layered in one of the music center, and it's all part of the circuit (including the record player) in a shell, this kind of structure is generally used for low-end hi-fi In layered component systems, depending on the grade of the machine divided by the number of layers is not the same component systems in more stratified: phonograph layer, CD player layer, layer tuner, dual card tape decks level, tone control layer, a layer of the main amplifier. In less hierarchical component systems, the record player, CD player sub-layer, the other for one. miniaturization, digitization, professional, film is the home audio inevitable trend.
