Relative Volume of Mics Explained

Relative Volume of Mics is a control that allows you to adjust the volume of all active microphones at once, without changing their individual balance. 

Where on the Hub can you find this?

Relative Volume is found in the OUT (Output) section for each specific output port, as it allows you to customize the mic level for each destination separately:

For RCA
 OUT -> MIXOUT -> RCA -> Output Settings -> Relative Volume of Mics

For 3-PIN
OUT -> MIXOUT -> 3-PIN -> Output Settings -> Relative Volume of Mics

Why would you need it?

It simplifies management. Instead of going back to the IN section and adjusting the Gain for each of the mics individually, you can perform one single adjustment that preserves your careful leveling. It acts as a final sanity check for your voice levels before they hit the speakers or the recording.

This feature controls only the Catchbox Plus microphones and any external inputs that have been specifically categorized as microphones in the Hub settings.

• Quick Global Adjustments: While you would typically use Output Gain for a general volume change (turning everything up or down), Relative Volume is useful if you only want to adjust the mic group for one specific destination while leaving media levels unchanged.
• Balancing Voice vs. Media: This is the primary reason this setting exists. If you are playing background music and the presenters’ voices are being drowned out, you can increase the Relative Volume to make the voices stand out clearly over the media.

Factory/Default setting

Default: 0dB.
At 0dB, the Hub passes the microphone signals through at their original levels. You can adjust this range from -20dB to 0dB to fine-tune your group mix.

Tip from Engineering

📣 While this might seem similar to Output Gain, it’s actually smarter. Output Gain turns everything up or down (including your computer audio/music), whereas Relative Volume only touches the microphones.
