Ensure all Catchbox mics are paired with the Hub.** In most cases, the mics are pre-paired before shipping. However, if pairing is required, follow the instructions in this [Knowledge Base article](https://help.catchbox.com/knowledge/how-to-pair-catchbox-mics-with-the-hub?hsLang=en).  **2. Connect the cables** - **USB** - connect Catchbox Hub DSP to your video conferencing computer using the included USB-C cable. It’ll provide power to the Hub DSP and send two-way audio to the computer. - **Active loudspeakers** - use appropriate cables to connect your active loudspeakers to Catchbox Hub DSP outputs “3-PIN L” (Left) and 3-PIN R” (Right). If necessary, use Catchbox XLR-3PIN Output Adapters (purchased separately). **3. Configure your Catchbox Hub DSP**  - Set Hub DSP to operate in “Speakerpone mode”. It’ll set USB audio to be recognized as both “Microphone” and “Loudspeaker” on the video conferencing computer. `GLOBAL SETTINGS → SYSTEM → USB DEVICE MODE → SPEAKERPHONE` - Configure audio mix for video-conference on USB OUT (MIXOUT) `OUT → MIXOUT → USB OUT → CHANNEL SETTINGS → MIX CONFIGURATION → MIC1–4, ENABLED``` NB! Disable all other signals. - Configure audio mix for loudspeakers on 3-PIN (MIXOUT) `OUT → MIXOUT → 3-PIN → CHANNEL SETTINGS → MIX CONFIGURATION → MIC1–4, USB-IN ENABLED` NB! Disable all other signals. **4. Configure your video conferencing computer** - In the computer's audio settings select “Catchbox Hub DSP” as a source of "Microphone" and “Loudspeaker” (depending on the OS). - In the video conferencing platform’s audio settings  select “Catchbox Hub DSP” as a source of "Microphone" and “Loudspeaker” (depending on the platform). - Enable all Video Conferencing platform processing. ### **Wiring and mix diagram** **![video + Loudspeakers](https://help.catchbox.com/hs-fs/hubfs/video%20+%20Loudspeakers.jpg?width=670&height=501&name=video%20+%20Loudspeakers.jpg)**   - [Catchbox Plus System](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#main-content) - [Overview](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#overview) - [Hub DSP receiver](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#hub-dsp-receiver) - [Hub features](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#hub-features) - [Stick Mic](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#stick-mic) - [Clip Mic](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#clip-mic) - [Cube Mic](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#cube-mic) - [System Firmware](https://help.catchbox.com/knowledge/catchbox-plus-system?hsLang=en#system-firmware) - [Product Setup](https://help.catchbox.com/knowledge/product-setup?hsLang=en#main-content) - [Product Setup](https://help.catchbox.com/knowledge/product-setup?hsLang=en#product-setup) - [Product Setup for Integrations](https://help.catchbox.com/knowledge/product-setup?hsLang=en#product-setup-for-integrations) - [How-to's](https://help.catchbox.com/knowledge/product-setup?hsLang=en#how-tos) - [Product Features](https://help.catchbox.com/knowledge/product-setup?hsLang=en#product-features) - [DECT Radio Protocol](https://help.catchbox.com/knowledge/product-setup?hsLang=en#dect-radio-protocol) - [Ordering & Shipping](https://help.catchbox.com/knowledge/ordering-shipping?hsLang=en#main-content) - [How to Order Plus System](https://help.catchbox.com/knowledge/ordering-shipping?hsLang=en#how-to-order-plus-system) - [Shipping](https://help.catchbox.com/knowledge/ordering-shipping?hsLang=en#shipping) - [Billing](https://help.catchbox.com/knowledge/ordering-shipping?hsLang=en#billing) - [Warranty & Returns](https://help.catchbox.com/knowledge/ordering-shipping?hsLang=en#warranty-returns) - [Microphone Customization](https://help.catchbox.com/knowledge/microphone-customization?hsLang=en) - [Troubleshooting](https://help.catchbox.com/knowledge/troubleshooting?hsLang=en#main-content) - [Technical Troubleshooting](https://help.catchbox.com/knowledge/troubleshooting?hsLang=en#technical-troubleshooting) - [Audio Quality Issues](https://help.catchbox.com/knowledge/troubleshooting?hsLang=en#audio-quality-issues) - [Mic Troubleshooting](https://help.catchbox.com/knowledge/troubleshooting?hsLang=en#mic-troubleshooting) - [Materials](https://help.catchbox.com/knowledge/materials?hsLang=en) - [Remote Control & Monitoring](https://help.catchbox.com/knowledge/remote-control-monitoring?hsLang=en) - [Beltpack Module](https://help.catchbox.com/knowledge/beltpack-module?hsLang=en) - [Discontinued](https://help.catchbox.com/knowledge/discontinued?hsLang=en#main-content) - [Catchbox Legacy Plus](https://help.catchbox.com/knowledge/discontinued?hsLang=en#catchbox-legacy-plus) - [Catchbox Mod](https://help.catchbox.com/knowledge/discontinued?hsLang=en#catchbox-mod) Copyright © 2026, Catchbox SIA
