It also accepts line-level audio signals from other audio sources, making it highly versatile for DIY wireless builds.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can multiple XL-MKF units operate in the same room without interference?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. Each unit pair uses digital encryption with assignable User IDs. Even if two pairs share the same UHF frequency band, setting different User IDs prevents any crosstalk between them — a major advantage over traditional FM-based wireless systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What batteries does the transmitter module require, and are they included?\u003c\/h4\u003e\n\u003cp\u003eA: The transmitter module uses AAA batteries, which are \u003cstrong\u003enot included\u003c\/strong\u003e. The receiver module features a built-in rechargeable lithium battery that charges via USB — this battery is included.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How noticeable is the 5 ms audio delay during karaoke or live performance use?\u003c\/h4\u003e\n\u003cp\u003eA: A 5 ms delay is virtually imperceptible to the human ear (the threshold for noticeable delay is typically above 20–30 ms). This makes the XL-MKF module well-suited for real-time singing, live vocals, and performance applications where audio-video sync is important.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the LCD display required for the module to function?\u003c\/h4\u003e\n\u003cp\u003eA: No. The LCD display on the transmitter is an optional convenience feature that shows the active channel and battery level.
