LINE 6 XD-V55 wireless microphone system, balanced output, AC power. The hinge on the microphone's battery cover is broken, so the cover comes off (see photo 6), but it can be reattached, and there are no issues with use if the battery case is in place. There are no problems with power, communication, or sound output. The microphone's On/Off switch is a little difficult to press. However, because the battery cover is detached, I've priced it a bit lower than the market rate (?). Thank you. - Brand: LINE 6 - Microphone Type: Wireless Microphone - Receiver Model: XD-V55 - Output Terminals: Balanced Output, Unbalanced Output - Included Accessories: AC Adapter - Number of Antennas: 2 - Power Supply: AC Power (Genuine) Thank you for viewing.
