FIELD: multi-channel acoustic systems. ^ SUBSTANCE: in accordance to the invention, back acoustic blocks are positioned in front of the listener, and multi-channel amplifier is additionally provided with a block for analog phase processing of sound signals which are received at inputs of back acoustic blocks, where output signal of left channel of sound signal analog phase processing block represents a signal which is the total of input signal of left back channel and inverted input signal of right back channel with changed level, and output signal of right channel of sound signal analog phase processing block represents a signal which is a total of input signal of right back channel and inverted input signal of left back channel with changed level. ^ EFFECT: creation of spatial sound, similar to volumetric sound of five-channel acoustic systems. ^ 1 dwg |
