I am about to purchase two SM81 microphones and would like to know if they are available in matched pairs. I have been unable to find a part number for such. Perhaps the SM81 design does not require matched pairs and I am looking for something that does not exist.
The SM81 is not available in a matched pair set. The quality of the microphone is such that you can purchase two SM81's at random and know that they will be the equivalent of a matched set.
