Jensen PI-2XX Stereo Audio Isolator Interface - 2 Channel XLR
The Model PI-2XX is designed to provide over 90dB of common mode isolation at 60Hz and to help eliminate R.F. interference and Hum from radio and television stations. Transformer isolation allows maximum interconnection flexibility, since both sources and loads may be either balanced or unbalanced. PI-1XX is a single channel Isolator.
