PHN 9698 24 ABSTRACT: An arrangement for the transmission of audio signals, comprising a delay line provided with tappings situated at equal time intervals along the delay line. The tappings are each connected to a common adding cir- cuit via an amplitude control device. The ratios be- tween the amplitudes of the output signals of the ampli- tude control devices, viewed from one end of the delay line to the other end are 1 : 2n : 2n2 : -2n : 1 for five tapping, 1 : 2n : 2n2 : n3 - n : -2n2 : 2n : -1 for seven tappings, and 1 : 2n : 2n2 : n3 - n : 1/4 (n4 -1) - 2n : -(n3 - n) : 2n2 : -2n : 1 for nine tappings. This yields an arrangement having a flat frequency res- ponse from the input to the output. The invention also relates to a plurality of delay lines which are connected in series with each other. The invention also relates to a reverberation unit provided with an arrangement in accordance with the invention.
