Applications
PI-2XX with a PA system
Eliminating noise in a PA system can take hours of trouble shooting, particularly when the mixer, amplifiers and speakers are distanced apart. Connect the PI-2XX at the input of your amplifier to eliminate ground loop hum and buzz.
PI-2XX in the studio
Recording and broadcast studios require a noise-free signal transfer while delivering the most accurate sound possible. The Iso-Max PI-2XX eliminates ground loops and lowers RF without introducing distortion, phase shift or artifact.
Isolating one console from another
Whether you are isolating two consoles in a festival or experiencing noise when connecting to a drive rack, the PI-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.
