This adapter screws into either an EC-SMK bracket, an Aviom MT-1 bracket or directly to the bottom of an Elite Core PMA or Hear Back mixer and attaches to either a microphone stand or an orchestral music stand. Use with the EC-SMK to mount a PM-16 below a music stand desk, or on the primary upright of a boom stand. Also can be used to hold an acoustic guitar mic while attached to a regular microphone stand.
