<p>The proposed spatial sound reproduction system comprises a signal source (1), a unit (2) for regulating amplitude-frequency characteristics, a low-frequency amplifier (3), a loudspeaker (4) connected in series, and a controllable attenuator (5) and a sounding device (6). The following components are also included: a device (7) for the automatic regulation of amplitude-frequency characteristics connected to the sounding device (6), and a switch (9) configured in such a way that it can disconnect the device (2) from the source (1) and amplifier (3) and connect the latter components to the device (7).</p> |
