What will you need?
- Catchbox Plus system with Networking Module
- DANTE audio network infrastructure
- Video-conferencing computer (USB Audio connection to Hub DSP)
- Ceiling array and loudspeakers (DANTE connection to Hub DSP)
Step-by-step instructions
1. 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.
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.
- Network cable - connect Catchbox Hub DSP’s network port to your DANTE network
Note on the Power - in case PoE is enabled - it is primary power supply for the 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 DANTE IN 1 port to MICROPHONE MODE
IN → DANTE → DANTE 1 → CHANNEL SETTINGS → MICROPHONE MODE
- Configure audio mix for video-conference on USB OUT
OUT → MIXOUT → USB OUT → CHANNEL SETTINGS → MIX CONFIGURATION → MIC1–4 ENABLED, DANTE IN CH 1 ENABLED
NB! Set all other signals to DISABLED.
- Configure audio mix for loudspeakers on MIXOUT 3-PIN
Note: Even MIXOUT 3-PIN output is not used, this configuration step is necessary for Feedback Suppression algorithm to be applied on Dante outputs.
OUT → MIXOUT → 3-PIN → CHANNEL SETTINGS → MIX CONFIGURATION → MIC 1–4, USB-IN ENABLED
NB! Set all other signals to DISABLED.
- Configure audio mix for ceiling array’s AEC reference signal on DANTE_OUT 1
OUT → DANTE → CH1 → CHANNEL SETTINGS → MIX CONFIGURATION → USB_IN → ENABLED
NB! Set all other signals to DISABLED.
- Clone 3-PIN audio mix for Dante-enabled loudspeakers on DANTE_OUT 2 and 3
OUT → DANTE → CH2 → CHANNEL SETTINGS → CHANNEL CLONING “ENABLED”, CLONING SOURCE → “3PIN LEFT”
OUT → DANTE → CH3 → CHANNEL SETTINGS → CHANNEL CLONING “ENABLED”, CLONING SOURCE → “3PIN RIGHT”
- You can find Catchbox Hub DSP’s network settings in
GLOBAL SETTINGS → NETWORK
- Route Catchbox Transmitter CH1 to the ceiling microphone's input AEC reference channel
- Route the ceiling microphone's Transmitter channel to Catchbox Receiver CH1
- Route Catchbox Transmitter CH2 to your Left loudspeaker
- Route Catchbox Transmitter CH3 to your Right loudspeaker
- 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).
