Radio Frequency (RF) Power Explained

💡 Radio Frequency (RF) Power is a setting that controls the strength of the wireless signal transmitted from your microphones to the Hub receiver. Adjusting this ensures a stable connection even if there are physical obstacles or long distances between the Hub and mics.

Where on the Hub can you find this?

Global Settings -> RF (Radio Frequency) -> RF Power

What is it for and why?

RF Power is like the volume of the wireless signal (not the audio itself). It’s designed to overcome physical obstacles or distance. Increasing the power helps the signal pass through walls or reach across larger halls.

Important: Increasing RF Power does not increase the volume of the microphones. It only makes the wireless signal louder so it can travel further or through walls.

❗Watch out for Interference. If you have multiple Hubs in nearby rooms, don’t set them all to maximum RF power. If they all shout at once, they’ll cause Radio Interference with each other, which can actually make the signal quality worse for everyone. Only increase the power if you actually experience signal drops.

Factory/Default setting

Level 3 (Three Bars/Blocks). 

The default setting is optimized for standard room sizes and works perfectly for the vast majority of setups.

When and why would you need to adjust it?

Consider increasing it if:

Construction Interference
Your room has thick walls or structures that create blind spots where the signal drops.

​​Hidden Hub Setups
Your Hub is tucked away in a separate technical room or equipment closet, but the microphones are being used in the auditorium next door.

Signal Drops
You notice the audio crackling or dropping out when a presenter moves to a specific corner of the room.

When is it Useful?

Large Auditoriums: When the distance between the presenter and the Hub is very large. Remember that Hub wireless range is 100m / 330ft. 

Challenging Layouts: When you need the signal to remain stable even if the presenter moves behind a pillar or a wall.

🔦 Simple Analogy 

The Shouting analogy

Imagine two people talking across a room. The default setting is a normal speaking voice. If one person moves to the next room, they need to shout (increase RF Power) to be heard.
