I am in Istanbul at the moment. A friend of mine gave me this what appears to be a two channel stereo microphone preamplifier made by Siemens. There is no production ID label on it, so all of my google searches did not return any info. Would anybody know anything about this?
It has two transformer coupled microphone input channels. Gain control for both channel is through 10 position stepped switches. Master volume is a single potentiometer. Bass and treble controls uses dual concentric potentiometers. I have not yet worked out what the push button switches do other than the one on the right which is for checking the battery level.
It is powered by both internal battery and external 9V DC power supply. It is a solid state equipment and has very high built quality. I am taking it with me (to Glasgow) to first work out how it works and then modify the inputs/outputs with XLRs for pro-use.
