XD-V55 gives you the flexibility to choose from four superb microphone models, so you can be confident you've got the right microphone sound to match your voice - and your performance. The included handheld transmitter features a premium capsule with cardioid pattern to reduce the risk of feedback. The signal from XD-V55 is so clear and strong that it sounds and performs like a wired microphone.

Ensuring peace of mind and the most reliable performance, the XD-V55 operates in the 2.4GHz band, which is free from interference due to TV broadcast, cell phone towers and other transmitting devices. Encoded DCL (Digital Channel Lock) technology prevents reception of any audio interference from other 2.4 GHz devices and ensures signal integrity. Road-ready and with 12 channels of 24-bit, 10Hz-20kHz, compander-free performance, XD-V55 provides unmatched full range audio clarity, one-step set-up and license-free operation worldwide.
