Applications
PO-2XX with a PA system
Eliminating noise in a PA system can sometimes take hours of trouble shooting, particularly when the mixer, amplifiers and speakers are distanced apart. Simply connect the PO-2XX at the output of your mixer to instantly eliminate hum and buzz caused by ground loops.
Isolating one console from the other
Whether you are isolating two consoles in a festival or experiencing noise when connecting to a drive rack, the PO-2XX is easily inserted into the signal chain to break the ground loop and eliminate noise as it easily handles huge bass transients without distortion.
