SoundStation2W: Specifications of the Auxillary Audio Port

Signal levels are the same for the auxillary jack ( )on the SoundStation2W Base, "AC" refers to frequencies between 200Hz and 3kHz. The following all refers to the REC signal unless otherwise stated:
  • Output: the AC impedance is < 5000ohms.
  • The signal has a DC impedance of 36K to +15V. Because of this, we recommend that connections to REC be AC-coupled, and that any external capacitor polarity take account of this +15V bias.
  • Path Gain, Output: 340 mV RMS (-7 dBm) at Tip/Ring produces 400 mV RMS (-5.7 dBm) nominal at AUX I/O.
  • For reference, saturation on the phone line is 0 dBm, and maximum sustained signal generally allowable is about -9 dBm (which is very loud).
