The Radial Twin-Iso is a balanced two-channel, line-level isolator that has been specifically developed for professional touring systems as a means to eliminate hum and buzz caused by ground loops when interfacing various equipment such as two consoles, remote towers and drive racks.
Central to the unit is the use of Jensen audio transformers. These assure the very best signal transfer without distortion caused by saturation or phase shift. All connections are balanced XLR following the AES standard with pin-1 ground and pin-2 hot.
To add versatility, a polarity reverse switch is provided for each channel to ensure absolute phase is maintained throughout the audio signal path.
