This is a used Voxx SingTrix Voice Effects Processor Karaoke 136-5503 . It has been tested for power and some of the functions as shown in the photos. When you click the hot button on the microphone it does turn the processor hit button on and off. The microphone wire screen is coming off on one side.

***I am not sure if it is the original ac adapter for the unit***. What you see in the photos is what you will be receiving. Should you have any questions or would like more photos please let me know. There are scratches and scuffs so, please review the photos for any wear and tear. Thank you!
