Applications
PI-XX 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-XX at the input of your amplifier to eliminate ground loop hum and buzz.
PI-XX in the studio
Recording and broadcast studios require a noise-free signal transfer while delivering the most accurate sound possible. The Iso•Max PI-XX eliminates ground loops and lowers RF without introducing distortion, phase shift or artifact.
