Choirflex Quick Start
1 - Install VUI
- Download the latest version of VUI on a computer connected to your Dante™ network.
2 - Connect and Power Up
- Mount the Choirflex unit in a rack, connect power, and connect the Network 1 port to your Dante™ network.
- Power the unit up by pressing the front panel power button. The unit will automatically receive an IP address (if you have a DHCP server on your network), or it will select a self-assigned address.
3 - Connect VUI to Choirflex
-
In the VUI software, navigate to the Processors tab and search for Choirflex under the Discovered list. If Choirflex does not appear, check your preferred network interface.
-
Click the Discovered icon to connect.
4 - Route Dante™ Audio
Dante™ Controller is used to patch audio in and out of Choirflex.
- Inputs 1 and 2 are the Choir inputs. Patch from an unprocessed stereo mix bus containing only your choir mics.
Start with only a high-pass filter at 60-80 Hz on each choir mic input. Do not route this mix bus, or the choir mics themselves to the main mix output feeding your loudspeakers!
-
Inputs 3 and 4 are the Reference inputs. Route a signal from the mixing console that matches the feed sent to your loudspeaker system (e.g., the main LR mix, etc.).
-
Outputs 1 and 2 are the Choir return outputs. Patch this signal back to a stereo input channel on the console that is mixed to the main mix output feeding your loudspeakers.
5 - Verify Levels and Console Settings
- Set the Liveness control to full (clockwise).
- Play back audio through the system at a normal volume as used during a performance.
- Verify that all 6 meters on VUI (choir input, reference and choir output) are reading at similar levels. Adjust your feeds from the console as necessary.
- Slowly bring up the return channel faders to allow the processor to adapt to the room.
- Continue adjusting levels up and down as necessary, letting feedback slightly ring out through the system.
6 - Mixing
- During soundcheck, constantly monitor input gains from the choir mics and choir return channels. Adjust as necessary.
- Once Choirflex has optimized it's processing, and levels are within the normal range throughout, you will only need to adjust the choir level on the return channels.
- You may use selective equalization on the choir return channels for taste and tonality. We do not recommend applying any equalization on the choir mic channels themselves beyond the simple high-pass filter.
