Claims

[Claims for Utility Model Registration] A recording head having a plurality of recording tracks in the opening of a cassette-type endless tape and a playback head having a plurality of playback tracks corresponding to the tracks. The audio signal recorded on the endless tape by the track is played back from the playback track corresponding to the recording track of the playback head, and the playback signal is transmitted through the amplifier and any recording track other than the above recording track of the recording head. Then, the same recording and playback as described above is repeated between a plurality of recording/playback tracks 1, and 'from a plurality of playback signals played back from each playback track of the playback head. An echo device characterized in that a plurality of types of audio signals with an echo effect can be obtained by selecting any one or more reproduction signals by a signal selection means and mixing them with the audio signal.
