How To Change Frequency On Wireless Microphone

How To Change Frequency On Wireless Microphone

Changing the frequency on a wireless microphone depends on the type of system you’re using (UHF, 2.4GHz, or VHF). Here’s a step-by-step guide for different scenarios:

1. UHF Wireless Microphones (Professional Systems)

Steps:

1. Check Compatibility

   • Ensure your mic and receiver are on the same frequency band (e.g., 470–698 MHz).

2. Access the Menu

   • On the receiver, press the Menu/Settings button.

   • Navigate to Frequency or Channel Selection.

3. Select a New Frequency

   • Choose an unused frequency (use a frequency scanner if available).

   • Avoid TV broadcast frequencies (in some countries, UHF channels 38+ are safe).

4. Sync the Transmitter (Mic)

   • On the mic’s body/pack, select the same frequency.

   • Some systems auto-sync when you press “Sync” on the receiver.

2. 2.4GHz Wireless Microphones

Steps:

1. Pairing Mode

   • Turn on the receiver and transmitter.

   • Press the Pair/Sync button on both devices (LED will blink).

2. Auto Frequency Selection

   • Most 2.4GHz systems auto-select the best frequency to avoid Wi-Fi interference.

   • Some allow manual selection via an app (e.g., Shure MOTIV).

3. VHF Wireless Microphones (Older Systems)

*(e.g., Audio-Technica System 10 VHF)*

1. Physical Switches/Dials

   • Adjust the frequency dial on the mic and receiver to match.

   • Avoid crowded VHF bands (e.g., 174–216 MHz).

4. IR Sync Systems

(e.g., Sony UWP-D)

1. IR Sync Port

   • Point the mic’s IR port at the receiver.

   • Press Sync on the receiver to transfer the frequency.

5. Troubleshooting Tips

• Interference? Use a frequency scanner .

• No Sound? Ensure both devices are on the same group/channel.

• Legal Frequencies: Check local regulations (e.g., FCC in the USA, Ofcom in the UK).
