UHF Wireless Mic Transceiver Module 24Bit HD Audio LCD | Elubor

UHF High-Fidelity Wireless Microphone Transceiver Module (XL-MKF)

Elevate your karaoke nights, live performances, and DIY speaker builds with the Elubor XL-MKF UHF Wireless Audio Transceiver Module. Engineered for audiophiles and makers alike, this compact transmitter/receiver pair delivers 24-bit / 48 kHz studio-grade digital audio over a secure UHF wireless link — no cables, no compromise.

Made in Mainland China.

Why Choose the XL-MKF?

• True High-Fidelity Audio – Uses an advanced ∑Δ A/D and D/A processing pipeline with DQPSK digital modulation. No compression, no pre-emphasis/de-emphasis — the original character of your sound is preserved, rivaling the clarity of a wired connection.
• Ultra-Low Latency – Only 5 ms transmission delay, making it ideal for real-time karaoke, live vocals, and wireless speaker applications where sync matters.
• Digitally Encrypted Transmission – Each unit pair can be assigned a unique User ID, eliminating crosstalk even when multiple units share the same frequency. RF interference only affects range — never introduces audio noise.
• Dual Frequency Bands – Easily switch between 750–759 MHz and 760–769 MHz (default) with a single button press.
• LCD Display on Transmitter – Clearly shows the active channel and remaining battery level at a glance. (LCD is optional and does not affect core wireless functionality.)
• Rechargeable Receiver – The receiver module charges via USB and includes a built-in lithium battery. LED indicators show connection status and charge level.
• Universal Dynamic Mic & Line Input – Compatible with any dynamic microphone or audio line-level signal wired directly to the transmission module's input interface.
• CE Certified – Meets European conformity standards for electromagnetic compatibility and safety.

Key Specifications

What's in the Box

• 1× Transmitter module with LCD display (AAA batteries not included)
• 1× Receiver module (lithium battery included)

How to Use

Transmitter Controls

1. Power On: Long-press the button to start.
2. Switch Frequency: Single press to toggle between the two UHF bands.
3. Power Off: Long-press the button to shut down.

Code Matching (Pairing)

1. Hold the transmitter button while powering on. Keep it held until the LCD shows a flashing horizontal line.
2. Power on the receiver — its LED will flash once, then stay solid, confirming a successful pair.
3. Release the button; press once more to wake the display. The receiver LED confirms the active connection.

Restore Default ID

With the transmitter off, press and hold the button. When the flashing horizontal line appears, release, then immediately press the button three times. Wait briefly — when the pilot indicator displays, the factory ID has been restored.

Wiring Guide

• Dynamic Microphone: Connect mic wires directly to the transmitter module's input — positive to M+, ground/shield to M−.
• Line-Level Audio Signal: Wire the audio source directly to the input interface using the same M+/M− terminals on the module's back panel.

Perfect For

• DIY karaoke microphone builds
• Custom wireless speaker systems
• Stage and DJ audio setups
• Maker/electronics projects requiring wireless audio

Frequently Asked Questions

Q: Is the XL-MKF UHF wireless module compatible with any dynamic microphone?

A: Yes — the XL-MKF transmitter module accepts any standard dynamic microphone via its M+/M− input terminals. It also accepts line-level audio signals from other audio sources, making it highly versatile for DIY wireless builds.

Q: Can multiple XL-MKF units operate in the same room without interference?

A: 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.

Q: What batteries does the transmitter module require, and are they included?

A: The transmitter module uses AAA batteries, which are not included. The receiver module features a built-in rechargeable lithium battery that charges via USB — this battery is included.

Q: How noticeable is the 5 ms audio delay during karaoke or live performance use?

A: 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.

Q: Is the LCD display required for the module to function?

A: No. The LCD display on the transmitter is an optional convenience feature that shows the active channel and battery level. The core wireless audio transmission functions fully without it.
