Arrangement for the transmission of audio signals

摘要

An arrangement for the transmission of audio signals, comprising a delay line (1) provided with 5, 7 or 9 tappings situated at equal time intervals along the delay line. The tappings are each connected to a common adding circuit (16) via an amplitude control device (9 to 13). The ratios between the amplitudes of the output signals of the amplitude control devices, viewed from one end of the delay line (1) to the other end are 1:2n:2n2:-2n:1 for five tappings, 1:2n:2n2:n3-n:-2n2:2n:-1 for seven tappings, and 1:2n:2n2:n3-n:1/4(n4-1)-2n2:-(n3-n):2n2:-2n:1 for nine tappings. This yields an arrangement having a flat frequency response from the input (2) to the output (15). The invention also relates to a plurality of delay lines (for example 31 to 35) connected in series and to a reverberation unit provided with such a transmission arrangement.
