Turntables output at phono level NOT line level so make sure your settings are correct to engage the phono pre-amp in the desk for the lower signal level.
Looking at the rear panel of the SA, the only way you can use the EQ is to hook the tape rec out to the EQ inputs, then the EQ outputs to the tape inputs. Then select tape monitor at the SA and your EQ will be working for you.
I wouldn't recommend it, as the microphone input is a low level signal, whereas the output of your Behringer is a much higher level signal. You would have to attenuate the signal from the Behringer before connecting it to the microphone input.
