SK 2000 pin configuration

Microphones

Pin 3 of the lemo is both the audio input at microphone level and the bias voltage for the microphone.

For most Sennheiser microphones (e.g. MKE2, HSP2, HS2, etc.) this requires the red wire to be soldered to pin 3 of the lemo and both the blue and the screen wires to be soldered to pin 1 and 2 of the lemo. 

For some Sennheiser microphones (e.g. ME2, ME4, ME3, etc.) this requires the centre wire (white or yellow) to be soldered to pin 3 of the lemo and the screen of the wire to be soldered to pin 1 and 2 of the lemo. 

To connect a standard dynamic microphone with a 3 pin XLR connector, you will need to make a special lead:

  • XLR pins 1&3 connected to lemo pins 1 and 2.
  • XLR pin 2 connected via an electrolytic capacitor to pin 3 of the lemo.
  • The capacitor should be around 10uF 10V. The positive terminal must be connected at the lemo end.

Instruments

For guitars, the tip of the guitar jack should go to pin 2 of the lemo. 

The sleeve of the guitar jack should go to pins 1 and 3 of the lemo.

Line Input

For an unbalanced line connect the signal to pin 2 of the lemo and the ground to pins 1 and 3 of the lemo. 

For a balanced line, connect the hot signal (XLR pin 2) to the pin 2 of the lemo. Connect the cold signal (XLR pin 3) and the ground (XLR pin 1) to both pin 1 and 3 of the lemo.
