RELAY G10S, an 11-channel wireless system. - Model: RELAY G10S - Included: 9V DC power adapter - Wireless transmitter: RELAY G10TⅡ - Number of channels: 11 Thank you for viewing. I am selling this because I no longer use it. I purchased it about two years ago. I used it for about a year, and haven't used it since, so it's in good condition. I will ship it with the original box. I will also include the cable in the fourth picture if you need it. Thank you.
