Digital wireless system featuring natural sound quality and easy setup. - Model Name: Relay G50 - Type: Digital Wireless System - Tone Characteristics: Compact and natural sound quality - Operability: One-step setup - Frequency Band: 12 channels - Accessories: DC-1 power adapter, cable, antenna, transmitter holder Thank you for viewing. I am selling this because I switched to a different system and no longer use it, although I used it for live performances. The fixing bracket on the back of the transmitter is missing. Instead, an ESP transmitter holder is included. The reason for this is that the lid wasn't very secure, and because it uses batteries, the power would sometimes cut out due to impact. This holder securely fixes the battery lid. The receiver has tape on it because it was fixed to a board. The cable included is an Oyaide screw-type cable. I replaced the standard cable because it would sometimes have poor contact due to vibration, causing the sound to cut out. The standard cable is not included. I used this set for live performances. I think it's ready to use immediately. It will be shipped in the original box.
