- Number of open microphones adjustable
- Control algorithm adjusts gain automatically
- Auto mixing parameters adjustable
- Up to 5 units can be linked for operation with 20 wireless microphones, link cables included
- User-friendly menu operation via bright LCD
- Last used microphone stays activated (switchable)
- Adjustable priority circuit for each microphone
- Automatic frequency scan (AFS) finds interface-free channels
- Lock function avoids accidental changing of settings
- Line input e.g. for multimedia applications from PC, laptop, MP3 players
- Balanced and unbalanced line outputs for PA or recording applications
- Rack installation, 1 U
- License-free and approved in large parts of the EU (please check Duplex Gap on a country-by-country basis)
