<p>The three-dimensional sound reproduction system comprises a multichannel signal source (1) and sound reproduction channels. Each sound reproduction channel comprises a low-frequency amplifier (2, 7) and loudspeakers (3, 8), these being connected in series, a probe device (4, 8), an automatic signal characteristics regulator (5, 10) and a communications link (6, 11). The output of the probe device (4, 9) is connected via the communications link (6, 11) to the first input of the automatic signal characteristics regulator (5, 10) whose second input is connected to the output of the signal source (1), whilst the output is connected to the input of the low-frequency amplifier (2, 7).</p> |
