What will you need?

  • Catchbox Plus system with microphones
  • Media device with analog audio output
  • Video-conferencing computer (USB Audio 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.
  • Active loudspeakers - use appropriate cables to connect your active loudspeakers to “3-PIN L” (Left) and 3-PIN R” (Right) outputs. If necessary, use Catchbox XLR-3PIN Output Adapters (purchased separately).
  • Media device - use appropriate cable to connect your media device to the 3-PIN FLEX 1 port (balanced audio). If necessary, use Catchbox XLR-3PIN Input Adapters (purchased separately).

Note: for stereo audio applications you can use two inputs by repeating the above step with FLEX 2 port.

 

  • Alternatively you can connect your media device to the AUX IN input port (3.5mm stereo connector).
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 FLEX ports to operate as inputs

GLOBAL SETTINGS → SYSTEM → FLEX MODE → INPUT

  • Configure FLEX 1 port to MEDIA MODE

OUT → FLEX → FLEX 1 → CHANNEL SETTINGS → MEDIA MODE

Note: It is recommended to route the media signals to bypass the Automixer (MEDIA MODE). If your external device is a microphone, it is recommended to route it via the Automixer (MICROPHONE MODE).

  • Configure audio mix for video-conference on USB OUT

OUT → MIXOUT → USB OUT → CHANNEL SETTINGS → MIX CONFIGURATION → 

  • MIC  1–4 ENABLED
  • FLEX IN 1 ENABLED

or

  • AUX IN ENABLED
    NB! Set all other signals to DISABLED.

NB! Set all other signals to DISABLED.

  • Configure audio mix for loudspeakers on MIXOUT 3-PIN

OUT → MIXOUT → 3-PIN → CHANNEL SETTINGS → MIX CONFIGURATION → 

  • MIC 1–4
  • USB-IN ENABLED
  • FLEX IN 1 ENABLED

or

  • AUX IN ENABLED

NB! Set all other signals to DISABLED.

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).
