This is the stereo microphone bar "23510" from K&M (Kaiser & Müller). It is an angle-adjustable type that allows you to attach two microphones to one microphone stand. It is 21.5 cm long and has a 3/8 inch screw thread. I bought it, but I never had a chance to use it. It has been stored without being used in practice. Please check the photos for the condition. There may be very minor scuffs from storage, but overall it is in clean condition. Everything shown in the photos is included. Recommended for those looking for a stereo recording setup or a setup with two microphones. Please check the screw thread size and other specifications to ensure compatibility with your equipment before purchasing.
