APDD-500 B (Acoustic device of distant act) is a compact and easy-to-transport acoustic system of notification of distant radius of action. APDD-500 B provides the transfer of clear, intelligible speech. Narrow-directed beam allows to reach the distance up to 2000 m. Widened frequency diapason provides strict transfer of words and intonation.
