DUALFEX PRO EX2200
4. AUDIO CONNECTIONS AND INSTALLATION
As standard, the BEHRINGER DUALFEX PRO is installed with electronically servo-balanced inputs. The
circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free
operation, even at high operating levels. Externally induced mains hum etc. will be effectively suppressed.
The audio inputs on the BEHRINGER DUALFEX PRO are balanced. If possible, connect the unit to other
devices in a balanced configuration to allow for maximum interference immunity.
