New Feature Overview
Four Balanced Inputs (FLEX IN) for External Audio Devices (Available Only on New Hubs)
Four Dante® Inputs (DANTE IN) for External Audio Devices
In-Room and Video Conferencing Processing – Added Controls
Output Mixer Matrix - New Features
Audio Level and Gain Control
- Input Gain Control (+/- 20dB in 5dB steps) added to all input channels (except USB IN)
- Mics (Cube, Clip, Stick), AUX IN, FLEX IN, DANTE IN
- Output Gain Control (+/- 20dB in 5dB steps) added to all output channels (except USB OUT)
- MIXOUT (RCA, 3-PIN), FLEX OUT, DANTE OUT
- USB OUT output level increased compared to previous product versions
Four Balanced Inputs (FLEX IN) for External Audio Devices (Available Only on New Hubs)
- FLEX balanced audio ports (previously called DIRECT) can now be configured as inputs or outputs via the user interface:
GLOBAL SETTINGS -> SYSTEM -> FLEX MODE
- Each FLEX IN signal can be separately routed:
- Through the Automixer (MICROPHONE input mode)
- Bypassing the Automixer (MEDIA input mode)
IN -> FLEX -> CHANNEL SETTINGS -> INPUT MODE -> MICROPHONE/MEDIA
Four Dante® Inputs (DANTE IN) for External Audio Devices
- 4x4 Dante (4 input and 4 output channels) available at all times
(Only for Hub DSPs with Networking Module)
- Each DANTE IN signal can be separately routed:
- Through the Automixer (MICROPHONE input mode)
- Bypassing the Automixer (MEDIA input mode)
IN -> DANTE -> CHANNEL SETTINGS -> INPUT MODE -> MICROPHONE/MEDIA
💡 What do the FLEX and DANTE inputs features enable?
Mixing and processing of external audio devices (e.g., microphones or media players) by the Hub DSP, eliminating the need for separate audio DSP hardware.
Mixing up to 8 Catchbox mics on a single output by daisy-chaining two Hub DSPs.
In-Room and Video Conferencing Processing – Added Controls
- Feedback suppression (in-room path)
- Improved algorithm (reduced false triggering)
- New Enable/Disable toggle added:
MIXOUT -> 3-PIN and RCA -> CHANNEL SETTINGS
- AutoLevel (video call path)
- Improved algorithm
- Sensitivity level adjustment added:
USB OUT -> CHANNEL SETTINGS
Output Mixer Matrix - New Features
- CLONING function added for FLEX and DANTE outputs. Enables routing of MIXOUT output mixes (RCA, 3-PIN, USB) to FLEX OUT and DANTE OUT:
OUT -> FLEX/DANTE -> CLONING - USB IN and AUX IN are now available for routing to DANTE outputs
💡 Why is "cloning" needed?
Allows audio mixes from both In-Room (with Feedback Suppression) and Video Conferencing (with AutoLevel) paths to be sent to FLEX OUT and DANTE OUT outputs.
System Tools and Settings
- Restore system to default settings:
GLOBAL SETTINGS -> SYSTEM - Power-saving toggle for Catchbox mics (Cube, Clip, Stick). Firmware update to v2.1 or later necessary.
IN -> CUBE/CLIP/STICK -> CHANNEL SETTINGS - Mixout 3-pin MIC/LINE output signal toggle:
MIXOUT -> 3-PIN -> CHANNEL SETTINGS - Transmitter Firmware version is now visible in the Catchbox Hub DSP user-interface:
IN -> CUBE/CLIP/STICK -> CHANNEL SETTINGS - QR code link to Knowledge Base added to the Hub DSP user-interface
- AES256 Encryption Key is renewed each time a Catchbox mic (Cube, Clip, Stick) is paired to a Hub
- Various user interface updates implemented
Additional API Functions
- Read-only mode
- Automixer weight adjustments
- High-Pass Filter (HPF) threshold settings for Mics, FLEX, and DANTE
