Hi,

Thanks for Your reply. Actually i'm not sure what is that module. I became an owner of two of that modules by accident, and now i try to figure out what is that.

On front there is "PMT" sign, 3-pos. switch "1%, OPER., 100%, three potentiometers titled "CALIBRATE" 100%, 1% and "0-ADJUST" and -20dB switch.

On the back there is one 23-pin connector ( http://www.gearslutz.com/board/attachmen ts/geekslutz-forum/262670d1321217149-neu mann-tev-equalizer-module-imag0402.jpg )

Label:
"Neumann (logo) Typ PTM 930. 01 Nr. A 121"

Inside here are two toroidal transformers, six opamps (MC1741SCP1) an two other IC's

PCB is signed"PTM 31747-100-A01 30H4"

That's all I can tell about it.
