The thesis deals with design of analog echo (delay) effect. It focuses on an effect, where the delay is realised by moving magnetic tape. Mechanic parts are taken from the Grundig ZK 120 tape recorder. Unlike previously developed effects of this type, the design is enriched with stereo expansion. Thesis contains design of circuits for recording and reading from magnetic tape, as well as measurements of impedance and transmission characteristics. The design emphasizes ease of use with other audio devices. The device was constructed and its features were measured.
