This is a set including the Line6 Relay G30 transmitter (bodypack), receiver, genuine AC adapter for the receiver (9V, center negative), and a 60cm cable (CLASSIC PRO). The transmitter's battery cover fits relatively snugly. The receiver shows some age-related dirt, but the exterior isn't overly sticky. However, the bodypack's belt clip is missing. Also, for external power use, a small hole has been made in the battery compartment for wiring (see photo 9). Communication and sound output have been confirmed on each channel. Four AA batteries for the transmitter are also included. Thank you. - Brand: LINE 6 - Model: RELAY G30 - Type: Digital Wireless System - Frequency Band: 2.4GHz - Number of Channels: 6 - Included Accessories: AC adapter, 60cm shielded cable, 4 AA batteries - Maximum Distance: 30 feet (approx. 9 meters) Thank you for viewing.
