Passive Stereo Audio Isolation
The APC ISO-202 is a passive stereo audio isolator designed for compatible mixers, amplifiers and audio equipment. It helps reduce ground-loop hum and some unwanted interference between connected devices without requiring an external power supply. Results depend on the equipment, wiring and source of the noise; it cannot guarantee removal of every type of audio noise.
Balanced and Unbalanced Connections
The unit supports balanced and unbalanced signal paths through XLR, RCA, 6.35 mm TRS and 3.5 mm stereo connections. This flexible connector layout can be used for signal isolation and balanced/unbalanced conversion in compatible audio systems.
