Thank you for viewing the product page. SOUND PURE Wireless Microphone 8011II ② Transmitters (Microphones 8011II x 2), receiver, antenna, power adapter, box included, mounting hardware, and other accessories are complete. Purchased as a used, excellent condition item in April 2025. Used less than once every two months. There is another set of items in similar condition, for a total of four channels. For those who purchase both sets, I will include a separately sold bracket to mount two receivers in a 1U rack, and four microphone holders. Please note: In principle, cancellations due to the customer's circumstances are not accepted. I strive to respond to questions as quickly and accurately as possible. Please make your purchase after you are fully satisfied. Thank you very much.
