audio-technica ATW-R1100J Audio-Technica Wireless Receiver, for SYSTEM10 series I am selling this because I have been using the company's stompbox-type receiver soon after purchase, and this receiver has not been used much. I paired it with a transmitter and checked the sound output, confirming that it works properly. The genuine adapter is included. It is also undamaged, so I think you can still use it for a long time.
