Thank you for viewing. DPA DAD6033 Micro Dot to Audio-Technica adapter. I introduced it about 10 years ago. I am selling it due to a system change. I used it with Audio-Technica's ATW-T93 and ATW-T930. Please note that it seems some Audio-Technica transmitters are not compatible. I cleaned it before listing. I attached a microphone and confirmed that it works without any problems. There is slight deterioration on the outer box. It seems this model has been discontinued as it has been updated with a new model. A new one costs nearly ¥20,000. I plan to list multiple items, so please feel free to consult with me about purchasing multiple items together. I will ship via Nekopos.
