Like you can se here on this copypast from http://www.hardwarebook.info/DIN_Audio
The output from the taperecorder pin 3 & 5 goes to the input pin 3 & 5 on the amplifier.
and when recording output from the amplifier pin 1 & 4 goes to the input pin 1 & 4 on the taperecorder.
But you have 2 amplifiers that means that the output from the amplifier (BM7000) pin 1 & 4, goes to the input pin 3 & 5 on theother amplifier (BS9000).
