In addition, if certain Fredenstein modules are used, like F600A, F601A, F602, F603A/B, F604, and
the F607, all operating parameters of theses modules are displayed as well.
Universal power supply: accepting mains voltages from 90V AC to 240V AC, 50 to 60 Hz.
Increased output currents: 6.4A or 640 mA per slot and +48V DC 0.3A
Auxiliary Audio Inputs and Outputs
Built-in Audio Routing: Modules can be daisy-chained by simply using the menu driven user
interface on the LCD.
Compressor buss linking: Compressor modules can be linked simply using the menu driven user
interface on the LCD as well.
Multilayer back-plane: Increased signal integrity and lower noise floor.
Ground-lift switching: In case of ground loops, the audio ground and the protective ground can be
disconnected. Please use only if absolutely necessary.
