Magnetotherapeutic apparatus for generating acoustically modulating electromagnetic field contains the digital player, two individual electroacoustic emitters with regulator of output voltage from player, and electronic unit with two circuits controlled by the same player. The first circuit contains the preamplifier with the connector for the individual electroacoustic emitters, output amplifier and dynamic head for group listening of phonograms. The second circuit contains the preamplifier, the amplifier and electric adapter for increasing voltage and output of the electric signal from amplifier with the connector for the inducer of the electromagnetic field. Both circuits have two poser supplies. The first power supply produces bidirectional voltage of ±5 V supplied to preamplifiers. The second power supply produces bidirectional voltage of ±15 V supplied to amplifiers. The power supplies are connected to the source of alternate current. |
