Applications

DIN-LI 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 DIN-LI at the input of your amplifier to instantly eliminate ground loop hum and buzz.

DIN-LI Isolating subs
The use of sub woofers in a PA system has become common in most touring setups. Use the DIN-LI to isolate the sub-woofer amplifier racks to eliminate ground loops without affecting the audio signal path. The DIN-LI is able to withstand tremendous signal levels without distortion.

DIN-LI in the studio
Recording and broadcast studios require a noise-free signal transfer while delivering the most accurate sound possible. The Iso•Max DIN-LI eliminates ground loops and lowers RF without introducing distortion, phase shift or artifact.
