Topic: RME Babyface Pro FS + Mechlabor STM 310

Need help adjusting the output level from the XLR outputs for tape recording. My Mechlabor STM 310 analog tape recorder is set to +6 dBu, and the card works only in +4 and +19 dBu output modes. In what position should the level control in TotalMix be positioned so as not to overload the tape?
